Rose = PowerHA support

POWER8 and POWER7 servers (rack/tower) are considered in this documentation. Blade Center and PureFlex adapters are not included. PCIe Gen1/Gen2 Power System slot insights

- Gen 1 slots are provided in the #5802/5803/5873/5877 12X I/O drawers - Gen 1 slots are provided in POWER6 servers

The information in this spread sheet is provided "as is". Though the authors have made a best effort to provide an accurate and complete listing of PCIe adapters available on IBM Power Systems, the user should also use other tools such as configurators, other documentation or IBM web sites to confirm specific points of importance to you.

This document will be stored as a tech doc and it is the authors' intent to refresh it over time. Therefore if you are using a version stored on your PC, please occasionally check to see if a newer version is available.

OS levels shown in this spread sheet are minimum versions and revisions required by the adapter. Technology Level, Technology Refresh, Service Pack PTF, machine code level, etc. requirements can be found at the following URL:https://www-912.ibm.com/e_dir/eServerPrereq.nsf

- Gen3 slots are provided in the POWER8 system units. They are either x8 or x16 slots. There are two x16 slots per socket and the remaining slots are x8. x16 slots have additional physical connections compared to x8 slots which allow twice the bandwidth (assuming there are adpaters with corresponding x16 capabilities). x8 and x4 and x1 cards can physically fit in x16 or x8 slots. 7-11-6-9 is a good thing to memorize for POWER8 Scale-out servers. A 4U 1-socket server has 7 PCIe slots. A 4U 2-socket server has 11 PCIe slots. A 2U 1-socket server has 6 PCIe slots. A 2U 2-socket server has 9 PCIe slots.

- Gen2 slots are provided in the Power 710/720/730/740/770/780 "C" model system units and in the Power 710/720/730/740/750/760 770/780 "D" model system units. Their machine type model numbers are 8231-E1C (710), 8202-E4C (720), 8231-E2C (730), 8205-E6C (740), 9117-MMC (770), 9179-MHC (780) and 8231-E1D (710), 8202-E4D (720), 8231-E2D (730), 8205-E6D (740), 8408-E8D (750), 9109-RMD (760), 9117-MMD (770), 9179-MHD (780)- Optional Gen2 slots are provided via the PCIe Riser Card (Gen2), FC = #5685, on the Power 720 and Power 740.

- Gen 1 slots are provided in the initially introduced Power 710/720/730/740/750/755/770/780 system units. Their machine type model numbers are 8231-E2B (710), 8202-E4B (720), 8231-E2B (730), 8205-E6B (740), 8233-E8B (750), 8236-E8C (755), 9117-MMB (770), 9179-MHB (780)- Optional Gen1 slots are provided via the PCIe Riser Card (Gen2), FC = #5610, on the Power 720 and Power 740.

.FH/LP Power Systems slot insights

LP slots are found in the Power 710/730 and in the optional 720/740 PCIe Riser card (#5610/5685) and in the PowerLinux 7R1/7R2FH slots are found in the Power 720/740/750/755/760/770/780 and in POWER6 servers and in the #5802/5803/5873/5877 I/O drawers

All Gen1 adapters are supported in any Gen2 slot (subject to any specific server rules, OS/firmware support, physical size card & slot)

Blind Swap Cassettes (BSC) for PCIe adaptersPower 770/780 system unit, the POWER7+ 750/760 have Gen4 BSCOther POWER7/POWER7+ system units do not have BSC

The 12X-attached I/O drawers #5802/5877/5803/5873 have Gen3 BSC

AIX users can use the lscfg command to determine an existing adapter's CCIN (Customer Card ID Number). IBM i users can use the STRSST command to determine an existing adapter's CCIN

Order the right form factor (size) adapter for the PCI slot in which it will be placed. No ordering/shipping structure has been announced by IBM Power Systems to order a conversion. So even though many of the PCIe adapters could be converted by changing the tail stock at the end of adapter to be taller (full high) or shorter (low profile), no way to do so has been announced. If demand for such a capability emerges, a method to satisfy it will be considered. Note that tailstocks are unique to each adapter.

Most Gen2 cards are supported only in Gen2 or Gen3 slots. The #5913 and ESA3 large cache SAS adapters and the #5899/5260 4-port 1Gb Ethernet are exceptions to this generalization. Also #EC27/EC28/EC29/EC30 have some limited Gen1 slot support.

"Down generation": If you place a Gen2 card in a Gen1 slot it will physically fit and may even work. But these adapters weren't fully tested in Gen1 slots and thus there is no support statement for this usage. Also be VERY careful of performance expectations of a high bandwidth Gen2 card in a Gen1 slot. For example, a 4-port 8Gb Fibre Channel adapter has about 2X the potential bandwidth than a Gen1 slot can provide.

Most Gen3 cards are supported only in Gen2 or Gen3 slots. The #EJ0L large cache SAS adapters and #EJ0J/EJ0M SAS adapters are exceptions to this generalization. The same caveat about putting unsupported adapters in a "down generation" PCIe slot Gen1 or

Feb 2013 note: The POWER7+ 710/720/730/740 are at a higher firmware level than the previous POWER7 710/720/730/740. Though the "C" model 710/720/730/740 have Gen2 slots, the new Gen2 adapters EN0A/B/H/J are not be tested/supported back on the "C" models. All Gen2 adapters supported on the "C" models are also supported on the "D" models. There is currently no plan to introduce higher firmware levels to the Power 710/720/730/740 "C" models.

CCIN can be used to find an ordering feature code of an installed adapter. The ordering feature code is used to find the feature code name, price, description, etc

(Ethernet Cables (twinax) for Power Copper SFP+ ports are active cables. Passive cables not tested/supported. Feat codes #EN01, #EN02 or #EN03 (1m, 3m, 5m) are tested/supported. Note these twinax cables are NOT CX4 or 10 GBASE-T or AS/400 5250 twinax. Transceivers are located at each end of the #EN01/02/03 cables and are shipped with each cable..

Active cables will work in all cases. Passive has potential risk of not working in some cases, but is lower cost. To simplify/confusion/error/support/debug issues, Power Systems specifically designates active cabling as the only support SFP+ copper twinax cable option. Use passive at your own risk and realize it is an unsupported and untested configuration from Power Systems perspective.

These cables are the same as for 8 Gb Fibre Channel cabling, but the distance considerations are not as tight. Power Systems Optical SFP+ ports include a transceiver in the PCIe adapter or Integrated Multifunction Card..

QDR cables for the #5283 and #5285 adapters which have been tested and are supported are the Copper 1m, 3m, 5m (#3287, #3288, and 3289) and Optical 10m, 30m (#3290, #3293). Both the copper and optical cables come with the QSFP+ transceivers permanently attached at each end. The adapters just have an empty QSFP+ cage

The 4-port Async adapter (#5277 and #5285) has one physical port on the card, but comes with a short fan-out cable which has 4 EIA-232 ports. The fan-out cable does not have its own feature code.

The 2-port Async adapter (#5289 and #5290 has two physical ports on the card which are RJ45 connectors. Feature code #3930 cables are to convert from an RJ45 connector to a 9-pin (DB9) Dshell connector. These converter cables are fairly generic and can be found at many electrical stores. This same #3930 is used on the Power 710/720/730/740 system unit to convert the serial/system ports to a DB9 connector. Order one converter cable for each of the two ports you plan on using

SAS adapter cable commentsThe InfoCenter generally has very good information about cabling SAS adapters

AE or YE cables attach to tape drivesAA cables connect between two PCIe2/PCIe3 SAS adapters with write cache

PCIe Gen1 adapters have a wider connector called "Mini-SAS". PCIe Gen2 adapters need either a HD (High Density) Mini-SAS connector or an HD Narrow Mini-SAS connector , PCIe Gen3 adapters need a HD Narrow Mini-SAS connector.

YO cables - the "tail" or "bottom of the y" connects to the adapter SAS port. The two connectors on the "top of the y" connect to an I/O drawer to provide redundant paths into the SAS expanders.

X cables -- the two "bottoms of the x" connect to two diiferent adapters' ports. The two "tops of the x" connect to an I/O drawer. This provides redundant paths into the SAS expanders and into redundant SAS adapters.

The new Gen3 SAS adapters have four SAS ports which are VERY close together and require a more narrow Mini-SAS HD connector. "Narrow" cable feature codes equivalent to the PCIe Gen2 SAS adapter cables in terms of length and electircal characterisitcs are announced with the PCIe Gen3 SAS adapters. The Narrow cables can be used on the PCIe Gen2 SAS adapters. The earlier "fatter" Mini--SAS HD cables are NOT supported on the new PCIe Gen3 SAS adapters since the connectors would jam together and potentially damage the ports on the back of the PCIe Gen3 card.

I/O Performance Limits Estimator Tool

Strongly suggest reading all the intro material before trying to use the tables

Table of content Overview/purpose of the tool Using /interpreting / adjusting sizing factors Sizing factors for Integrated I/O, 12-X drawers, Ultra Drawer, 4X IB GX adapter The tables Optionally read: sharing bandwidth by PCIe slots

OVERVIEW / PURPOSE OF THE TOOL

This tool is intended as a rough rule of thumb to determine when you are approaching the IO limits of a system or IO drawer.

These sizing factors are actually rough Gb/s values. So a sizing value of 8 equates to 8Gb/s.

HOWEVER there are many variables and even more combinations of these variables which can impact the actual resulting performance in a real environment. Thus always apply common sense and remember this is designed to be a quick and simple approach ... a rough sizer. This is not a heavy-weight tool full of precise measurements and interactions. Keep in mind the key planning performance words, "it depends" and "your mileage may vary".

You will be using the "Sizing Factor" for each PCIe adapter. These are found in the "PCIe Adapter" worksheet/tab of this spreadsheet. Look for the light blue columns.

For example, feature code #5769 (10Gb 1-port Ethernet adapter) it has a sizing factor of 5 to 10. If high utilization, use "10" for the value. If low usage, use a "5". Or pick a number "6" or "7" or "8" or "9" if you think it is somewhere in between.

Or another example, feature code #5735 (8Gb 2-port Fibre Channel Adapter) has a sizing factor of 16 assuming both ports are being used. But if only one port is used, then use an "8".

Totaling all the sizing factors for all the adapters will give you a good idea if you are coming close to a performance limit for your I/O. You will be looking at an overall system performance limit as well as "subsystem limits" or "subtotal". Subsystem limits are maximums per an individual GX bus, system unit, I/O drawer, PCIe Riser Card, etc. The maximum Gb/s for each subtotal/subsystem and the overall POWER7 system are found further down on this worksheet.

NOTE1: these values do NOT translate directly into MB/s numbers. This tool builds on the observation that most adapters are rarely run at 100% utilization in real client application environments. Thus to help avoid over configuring for most shops, the tool assigns max performance factors that are 70-75% of the the maximum throughput technically/theoretically possible.

NOTE2: If you are correlating these bandwidth maximums to the bandwidth values provided in marketing presentations and in the facts/features document, observe that there is a difference. The marketing materials are correct, but use peak bandwidth and assume full duplex connections. This sizing tool takes a more conservative approach which probably represents more typical usage by real clients. It assumes simplex connections and sustained workloads in its maximums.

For example. For simplicity, marketing materials provide a single performance value of 20Gb/s for GX adapters/slots. The details behind this are that a GX adapter or 12X Hub specifications are: BURST = 10 GB/s simplex & 20 GB/s duplex SUSTAINED = 5 GB/s DMA simplex & 8 GB/s duplex.

This tool uses Gb (bit) vs GB (byte) because there is a lot of variability between different protocols/adapters and how their GB ratings translate into Gb and vice versa.

Comments/insights on how to use, interpret and/or adjust sizing factors

So SAS adapter rough guides

#ESA1 / ESA2 runs only SSD so use 28 per adapter unless lightly loaded or unless not that many SSD. Pairs are optional.

~~ #2053 / 2054 / 2055 runs only SSD so use a 6 if all four SSD are present. These adapters are not paired (but can be mirrored).

Remember to ask those common sense questions. "Are these adapters being run at the same time?" For example if you have an 8G FC port that only goes to a tape that only runs one night a week when other adapters are not busy, you probably do not need to count it at all in the performance analysis. Or another good question, "Do you have redundant adapters or ports which are there only in case the primary adapter/port fails?" If you do, then you can probably ignore the redundant adapter/ports.

For Fibre Channel and for Ethernet ports, simplex line rates are assumed, not duplex. Based on observations over the years this is a good simplification. Many client workloads aren't hitting the point where these adapters' duplex capability is a factor in calculating throughput. If your environment is a real exception and you know you have a really heavy workload using duplex, then add another 20-25% to the sizing factor.

The actual real data rates in most applications are typically less than the line rate. This is especially true for 10Gb Ethernet where many applications run the adapter at less than 50% of line rates. If you know this is true for you, cut the sizing factor in half (think of it as a 5Gb Ethernet adapter)

Similarly, if you have an 8Gb or 16Gb Fibre Channel adapter and it is attached to a 4Gb switch, then treat it like a 4Gb adapter (cut the 8Gb sizing factor in half). Likewise if you have a 16Gb FC adapter on an 8Gb switch, treat it lke an 8Gb adapter.

For Fibre Channel over Ethernet Adapters (FCoE or CNAs) Treat these adapters based on the mix of work done. If using one port for Fibre Channel only, treat it just like the 8Gb Fibre Channel adapter port above. If using a port solely for NIC traffic, treat it like a 10Gb Ethernet port above. If a port has mixed FC and Ethernet workloads, assign a sizing factor based on the mix.

SAS Adapters Don't be surprised by SAS adapters max throughput numbers. A 2-port, 6Gb adapter is not 2 x 6 = 12Gb/s multiplication. You are over looking the insight that each port/connector is a "x4" connection. Four paths per connection yielding a 2 x 6 x 4 = 48Gb/s outcome. It's bigger than a 2-port 8Gb Fibre Channel card ( 2 x 8 = 16), but then you could go into duplex mode for FC and 2 x 16 = 32 ... so much closer to 48 of the SAS 2-port. Also remember most SAS adapters run in pairs so that makes the comparison more challenging. "It all depends".

Usually there are a lot of SAS ports for connectivity and the per port workload is lighter. And remember there can be a huge, huge difference between SSD and HDD.

Also note there is a big difference in typical workload whether there is a lot of data / database workload and something easy like AIX/Linux boot drives. Boot drives are a very light load.

Transaction workloads focus on IOPS (I/O Operations Per Second) and have lower data rates. Reduce the SAS sizing factor if HDD is running transaction workload. You would probably reduce the sizing factor even if SSD running transactions workloads, but SSD are so fast you might leave the value higher even if transaction workload. Alternatively, if you are doing data mining or engineering scientific, or handling large video files where there are large block transfers, then Gb/s are high and use the larger sizing factor for the SAS controller.

~~ #5901 / 5278 is a 6 if running lots of drives with large data blocks or is a 1 if just supporting boot drives. If configured as a pair, or as dual adapters, each adapter has that same sizing factor. So a sizing factor for a pair could be up to 12. Paris are optional.

~~ #5805 / 5903 is an 8 if running lots of drives with large data blocks (especially SSDs) or a 1 if just doing boot drives. These adapters always work as pairs, and each of the pair has this sizing factor. The total sizing factor for a pair could thus be up to 16 with large block workloads.

~~ #5913 or #ESA3 is a 30 if running lots of SSDs or a 16 if running lots of HDDs. These adapters always work as pairs, and each of the pair has this sizing factor. The total sizing factor for a pair could thus be up to 60 with lots of SSD.

note that "lots" of SSD can vary whether you are running the newer 387GB SSD which are faster and have higher throughput than the 177GB SSD.

Sizing factors for Integrated I/O, 12-X attached I/O drawers, EXP30 Ultra Drawer and 4X IB adapter

Integrated IO Controllers

12X- attached I/O Drawers with PCIe slots #5802/5877 and #5803/5873

#5685 PCIe Gen2 Riser Card in Power 720/740 ("B" or "C" models)This 4-slot expansion option plugs into the GX++ slot. It's max throughput is 60 Gb/s#5610 PCIe Gen1 Riser Card in Power 720/740 ("B" model only)This 4-slot expansion option plugs into the GX++ slot. It's max throughput is 40 Gb/s

NOTE: the table below assumes #5685 is used …. If #5610 is used, subtract 20 Gb/s from the system max and the riser card

Gen2/Gen1 note: The tool below ignores differences in Gen2 PCIe adapters in Gen1 PC slots. You will have to keep this in mind if using a #5913 or #ESA1 (SAS adapters) and assume a max of 15 vs 30. (remember IOPS is not usually related to bandwidth limitations.) Most of the time Gen2 adapters are only supported in Gen2 slots, so it is not commonly a consideration.

The 710 through 780 have integrated controllers for running HDD/SSD, DVD, tape, USB ports. The "B" models have IVE/HEA which are 10Gb or 1Gb Ethernet. You need to include these in the calculations. You might ignore the DVD and USB as they are generally very small numbers whose peaks (if any) happen at off hours. Likewise the 1Gb Ethernet is small. But If you have integrated 10G E or the Dual RAID SAS options you need to include them in the calculations. Treat the integrated 10Gb Ethernet adapter like a PCIe 10Gb Ethernet adapter with the same number of 10Gb ports.

For a rough guide for the for the integrated Dual RAID controllers: You may be up to a 10 for the integrated pair (not 10 each). The 10 would be if you have some SSD or a lot of HDDs doing large block I/O. Remember that you can attach an #5887 EXP24S to the SAS port on the back of the server and then this same pair of integrated SAS controllers is handling another 24 SAS bays. Increase the sizing factor closer to 10 if running lots of drives -- especially if using large block I/O.

If you are NOT using the "dual" integrated SAS adapter option and using a "single" integrated SAS adapter, use the same performance factor as a #5901 / 5278 SAS adapter with a performance sizing factor or 1-6. For the Power 770/780 you can have two of these single adapters, each with their own sizing factor. If a Power 710/720/730/740/750/755 you would have just one adapter with one sizing factor.

This tool focuses on the total bandwidth available to you. These I/O drawers attach to GX++ Adapters and it is that GX adapter which sets the maximum bandwidth available to all the adapters in that drawer. If you have two I/O drawers on that same GX++ adapter, the two drawers share that same total bandwidth of the GX++ adapter. Having two vs one #5802/5877 provides some redundancy and obviously provides more slots, but does NOT increase max bandwidth. Note that each #5803/5873 is logically two drawers and for higher bandwidth you would cable the drawer to two GX++ adapters.

For this estimator tool, one GX+ bus will support 40 Gb/s and a GX++ bus will support 60 Gb/s. (see Note2 above) GX+/++ buses can "internal" or they can be "external". External GX buses are accessed through a GX slot. All of the external GX slots are GX++ on POWER7 servers except for the first GX slot on the Power 750.

Note that some servers share a bus for internal as well as for GX slots. Thus you'll see below times when the total bandwidth is less than the sum of the parts.

Note the Power 750 has two different GX adapters. The #5609 is GX+ (40Gb) and #5616 is GX++ (60Gb). If a #5609 is placed in the second GX++ slot, the bandwidth is restricted to 40Gb/s.

The Tables

1- Look up the sizing factor for each of the adapters. Make sure you know in which PCI slot the adapter(s) will be used.

3- For the subgroups which have internal I/O, also add the sizing factor(s) for the internal I/O

For Power 710/730 … "B" models

The #EDR1 EXP30 Ultra Drawer attaches to a GX++ PCIe adapter placed in the GX slot of a "D" model 710/720/730/740/750/760/770/780 or a "C" model 770/780. .The #5888 EXP30 Ultra Drawer attaches to a GX++ PCIe adapter placed in the GX slot of a "C" model 710/720/730/740. Inside the Ultra Drawer are two very high performance SAS controllers, more powerful than the #5913/#EAS3. So assume a sizing factor value of 60 for this drawer if a lot of busy SSD. Note each SAS controller has a PCIe cable connecting it to the GX++ PCIe adapter, but the cables can be plugged into different GX++ PCIe adapters. Thus assume a sizing factor of 30 for each cable plugged into the GX slot.The GX++ PCIe adapters are the #EJ03 and #EJ0H.and #1914 #EJ03 plugs into a 720/740. #EJ0H plugs into a 710/730. #1914 plugs into a 750/760/770/780.

This specialized adapter is used only on the Power 710/730 "B" model 8231-E2B to connect to a 4x Infiniband switch in server clustering environments. (On 710/730 "C" models with PCIe Gen2 slots, the QDR PCIe adapter is used instead of this DDR option.) The adapter supports up to a max of 30Gb/s. Actual usage is HIGHLY dependent upon the clustering application. Use a sizing factor of 2 - 30 depending on the applications. A modest percentage of servers user this GX++ adapter.

How to use the tables below: (see also the example just below Power 710/730 B models and the example just below Power 720/740 C models.)

2- Add the maximum sizing factor of each adapter in that subgroup of PCIe slots represented by a separate column in the tables below. Do this for all subgroups which your server will be using.

4- Compare each subgroup's sizing factor total to the subtotal maximum. 4a- If the sizing factor total is less than the subtotal maximum, you easily have adequate bandwidth. 4b- If the total sizing factor total is larger than the subtotal of the column, take action. Review the sizing factors and adjust downward as appropriate. Compare the revised sizing factor total to subgroup maximum. If still too high, take action such as moving adapters out of that subgroup.

5- . Then add the subgroups together and compare to the total bandwidth available for the server. If the adapters within a subgroup have a larger total sizing factor than the subgroup maximum, use the smaller value. 5a- If your total of subgroups is less than or equal to the system total, you should have adequate bandwidth. 5b- If your total of subgroups exceeds the system total, see if additional sizing factor adjustments would be helpful and compare again. If the system total is still exceeded, take appropriate action or make sure expectations have been set with the client.

Important insight: This tool focuses on aggregate bandwidth with subtotals. The "subtotals" or "subsystem limits" are important. Though individual Gen1 or individual Gen2 PCIe slots are the same, groups of Gen1 PCIe slots or groups of Gen2 PCIe slots sometimes share bandwidth. Bandwidth can also be shared with other internal I/O. The table below lays out the subtotals and the total. If you exceed the bandwidth of a subtotal, for example a GX slot, that means you have a bottleneck which will limit max throughput of the adapters located in that group of PCI slots.

Example: Power 730 B model. (See the table just above this row.) In the system unit (internal four slots) you have two 2-port 8Gb Fibre Channel adapters (sizing factor 16) and one 4-port 1Gb Ethernet adapter (sizing factor 0.4-4). (One of the PCIe slots is empty). You have three 177GB SSD in the six SAS bays run by the integrated SAS adapter (sizing factor up to 10) and you have a 2-port 10Gb Ethernet IVE/HEA (sizing factor 10-20 ). In this example the GX slots are not being used. You get the sizing factors from the "PCIe Adapter" worksheet/tab for the PCIe adapters and from the text above for the integrated I/O. B152

Example: Power 730 B model continued. Totaling the max sizing factors for these components yield 16+16+4+0+10+20 = 66. (16+16+4+0 = PCIe slots and 10+20 = internal.) 66 is larger than the 40 Gb/s max bandwidth available as shown in column C of the 710/730 B Model table above. So you need to review these number to see if a lower more realistic sizing factor value should be used instead of the 16+16+4+0+10+20 maximums. If after the review and assignment of lower sizing factors you are still above 40Gb/s, you need to move some I/O to the 2nd GX slot in an I/O drawer. Or you could switch to a 730 C model and gain a lot of bandwidth.

Totaling the max sizing factors for thes internal components yield 8+20+20+0.2+0+4+10 = 62.2 (PCIe slots = 8+20+20+0.2+4 and internal = 10.) 62.2 is larger than the 60 Gb/s max bandwidth available for these internal slots so you need to need to analyze the sizing factors to determine if they actually use less bandwidth. Let's assume you do so and the revised total is less than 60 ... which we'll call "Adjusted 62.2". example continued below

Next look at the GX slot size factors of 6+6 = 12. 12 is less than 60 so you are ok on this subtotal. Finally since on the Power 720, there is an overlap of bandwidth between the 1st GX slot and internal slots add all these sizing factors together. "Adjusted 62.2" + 12 is less than 100Gb/s so you fit in the system maximum as well as both subtotal maximums. Your configuration's bandwidth requirements should be ok.

As shown in the tables above, not all PCIe slots are equal. Individually they are equal, but depending on the server or depending on the I/O drawer, some slots share bandwidth with other slots or I/O. The following sentences summarize the tables above for the servers' PCIe slots.

Power 795 has no PCI slots in the system unit -- everything attached through GX++ slots

PCIe Riser Card#5610 which can be placed in the 720/740 "B" system unit …. All PCIe slots (Gen1) are equal#5685 which can be placed in the 720/740 "B or C" or "D" system unit …. All PCIe slots (Gen2) are equal

12X-attached PCIe I/O drawers: #5802/5877 (19-inch rack) and #5803/5873 (for 795/595)

Power 750/760 "D" model system units --- All PCIe slots are NOT equal. Individual slots are equal, but slots 1-4 are on one bus and slots 5-6 are on a separate bus which shares bandwidth with internal controllers

Power 770/780 "B" and "C" and "D" model system units --- All PCIe slots are NOT equal. Individual slots are equal, but slots 1-4 are on one bus and slots 5-6 are on a separate bus which shares bandwidth with internal controllers

The bandwidth available to a one or more I/O drawers on a 12X loop is obviously the same as the GX slot to which they are attached. Thus for this rough sizing tool's perspective, it usually doesn't make sense to to worry about individual PCIe slots within the I/O drawer. Most of the time trying to optimize PCIe card placement within an I/O drawer for most client workloads won't make that much difference. However, for those people who are focused on the details, the following information is shared. See Info Center for more detail.

#5802/5877 when only one drawer per GX adapter (one per 12X loop). A drawer has 10 PCIe Gen1 slots and two connections to the GX adapter in the server. The ten PCIe slots are in 3 subgroups; Slots 1,2,3 and Slots 4,5,6 and Slots 7,8,9,10. Slots 1,2,3 and Slots 4,5,6 each have a separate connection to the GX adapter. Slots 7,8,9,10 first connect to the Slot 1,2,3 subgroup and share the bandwidth of the Slot 1,2,3 connection to the GX adapter. Thus there may be a slight advantage in putting the highest bandwidth adapters in Slot 4,5,6 and also in putting the adapters with the least latency requirements in Slots 1,2,3 or 4,5,6. HOWEVER, most of the time this will not make much (if any) noticeable difference to the client assuming your total bandwidth need is reasonable.

#5802/5877 when two drawers per GX adapter (two per 12X loop). Each drawer will have a connection to the GX adapter. All three PCIe subgroups in a drawer share that one connection. Depending on the cabling used either Slots 1,2,3 or Slots 4,5,6 will be the "closest" to that connection upstream to the GX adapter. The other two PCIe subgroups will connect through the "closer" PCIe subgroup. HOWEVER, most of the time where the PCIe adapter is placed in the drawer will not make much (if any) noticeable difference to the client. The fact two drawers share the total GX adapter bandwidth can make a difference. So where I/O bandwidth is a consideration, try to use just one I/O drawer per loop. Generally try to balance the bandwidth needs across the to I/O drawers.

#5803/5873 have 20 PCIe slots. Think of this drawer as logically two 10 PCIe drawers inside one drawer. You can attach each half of a drawer to a GX adapter or you can attach both halves of a drawer to single GX adapter. Each of the two logical drawers each are identical to a #5802/5877 described above.

For the extremely analytical reader … Each #5802/5877/5803/5873 PCIe slot subgroup is on its own PCIe 8x PHB. Specifications for this PHB are: BURST = 2 GB/s simplex & 4 GB/s duplex SUSTAINED = 1.6 GB/s simplex & 2.2 GB/s duplex. Most of the time, this level of granular detail is not useful in client configuration sizings.

Sizing factors for Integrated I/O, 12-X drawers, Ultra Drawer, 4X IB GX adapter

This tool is intended as a rough rule of thumb to determine when you are approaching the IO limits of a system or IO drawer.

HOWEVER there are many variables and even more combinations of these variables which can impact the actual resulting performance in a real environment. Thus always apply common sense and remember this is designed to be a quick and simple approach ... a rough sizer. This is not a heavy-weight tool full of precise measurements and interactions. Keep in mind the key planning performance words, "it depends" and "your

You will be using the "Sizing Factor" for each PCIe adapter. These are found in the "PCIe Adapter" worksheet/tab of this spreadsheet. Look for

For example, feature code #5769 (10Gb 1-port Ethernet adapter) it has a sizing factor of 5 to 10. If high utilization, use "10" for the value. If low usage, use a "5". Or pick a number "6" or "7" or "8" or "9" if you think it is somewhere in between.

Or another example, feature code #5735 (8Gb 2-port Fibre Channel Adapter) has a sizing factor of 16 assuming both ports are being used. But if

Totaling all the sizing factors for all the adapters will give you a good idea if you are coming close to a performance limit for your I/O. You will be looking at an overall system performance limit as well as "subsystem limits" or "subtotal". Subsystem limits are maximums per an individual GX bus, system unit, I/O drawer, PCIe Riser Card, etc. The maximum Gb/s for each subtotal/subsystem and the overall POWER7 system are found

: these values do NOT translate directly into MB/s numbers. This tool builds on the observation that most adapters are rarely run at 100% utilization in real client application environments. Thus to help avoid over configuring for most shops, the tool assigns max performance factors that

: If you are correlating these bandwidth maximums to the bandwidth values provided in marketing presentations and in the facts/features document, observe that there is a difference. The marketing materials are correct, but use peak bandwidth and assume full duplex connections. This sizing tool takes a more conservative approach which probably represents more typical usage by real clients. It assumes simplex connections

For example. For simplicity, marketing materials provide a single performance value of 20Gb/s for GX adapters/slots. The details behind this are that a GX adapter or 12X Hub specifications are: BURST = 10 GB/s simplex & 20 GB/s duplex SUSTAINED = 5 GB/s DMA simplex & 8

This tool uses Gb (bit) vs GB (byte) because there is a lot of variability between different protocols/adapters and how their GB ratings translate into

#ESA1 / ESA2 runs only SSD so use 28 per adapter unless lightly loaded or unless not that many SSD. Pairs are optional.

~~ #2053 / 2054 / 2055 runs only SSD so use a 6 if all four SSD are present. These adapters are not paired (but can be mirrored).

Remember to ask those common sense questions. "Are these adapters being run at the same time?" For example if you have an 8G FC port that only goes to a tape that only runs one night a week when other adapters are not busy, you probably do not need to count it at all in the performance analysis. Or another good question, "Do you have redundant adapters or ports which are there only in case the primary adapter/port

ports, simplex line rates are assumed, not duplex. Based on observations over the years this is a good simplification. Many client workloads aren't hitting the point where these adapters' duplex capability is a factor in calculating throughput. If your environment is a real exception and you know you have a really heavy workload using duplex, then add another 20-25% to the sizing factor.

The actual real data rates in most applications are typically less than the line rate. This is especially true for 10Gb Ethernet where many applications run the adapter at less than 50% of line rates. If you know this is true for you, cut the sizing factor in half (think of it as a 5Gb Ethernet

Similarly, if you have an 8Gb or 16Gb Fibre Channel adapter and it is attached to a 4Gb switch, then treat it like a 4Gb adapter (cut the 8Gb sizing factor in half). Likewise if you have a 16Gb FC adapter on an 8Gb switch, treat it lke an 8Gb adapter.

Treat these adapters based on the mix of work done. If using one port for Fibre Channel only, treat it just like the 8Gb Fibre Channel adapter port above. If using a port solely for NIC traffic, treat it like a 10Gb Ethernet port above. If a port has mixed FC and Ethernet workloads, assign a sizing factor based on the mix.

Don't be surprised by SAS adapters max throughput numbers. A 2-port, 6Gb adapter is not 2 x 6 = 12Gb/s multiplication. You are over looking the insight that each port/connector is a "x4" connection. Four paths per connection yielding a 2 x 6 x 4 = 48Gb/s outcome. It's bigger than a 2-port 8Gb Fibre Channel card ( 2 x 8 = 16), but then you could go into duplex mode for FC and 2 x 16 = 32 ... so much closer to 48 of the SAS 2-port. Also remember most SAS adapters run in pairs so that makes the comparison more challenging. "It all depends".

Usually there are a lot of SAS ports for connectivity and the per port workload is lighter. And remember there can be a huge, huge difference

Also note there is a big difference in typical workload whether there is a lot of data / database workload and something easy like AIX/Linux boot

Transaction workloads focus on IOPS (I/O Operations Per Second) and have lower data rates. Reduce the SAS sizing factor if HDD is running transaction workload. You would probably reduce the sizing factor even if SSD running transactions workloads, but SSD are so fast you might leave the value higher even if transaction workload. Alternatively, if you are doing data mining or engineering scientific, or handling large video files where there are large block transfers, then Gb/s are high and use the larger sizing factor for the SAS controller.

~~ #5901 / 5278 is a 6 if running lots of drives with large data blocks or is a 1 if just supporting boot drives. If configured as a pair, or as dual adapters, each adapter has that same sizing factor. So a sizing factor for a pair could be up to 12. Paris are optional.

~~ #5805 / 5903 is an 8 if running lots of drives with large data blocks (especially SSDs) or a 1 if just doing boot drives. These adapters always work as pairs, and each of the pair has this sizing factor. The total sizing factor for a pair could thus be up to 16 with large block workloads.

~~ #5913 or #ESA3 is a 30 if running lots of SSDs or a 16 if running lots of HDDs. These adapters always work as pairs, and each of the pair has this sizing factor. The total sizing factor for a pair could thus be up to 60 with lots of SSD.

note that "lots" of SSD can vary whether you are running the newer 387GB SSD which are faster and have higher throughput than the 177GB SSD.

Sizing factors for Integrated I/O, 12-X attached I/O drawers, EXP30 Ultra Drawer and 4X IB adapter

NOTE: the table below assumes #5685 is used …. If #5610 is used, subtract 20 Gb/s from the system max and the riser card

The tool below ignores differences in Gen2 PCIe adapters in Gen1 PC slots. You will have to keep this in mind if using a #5913 or #ESA1 (SAS adapters) and assume a max of 15 vs 30. (remember IOPS is not usually related to bandwidth limitations.) Most of the time Gen2

The 710 through 780 have integrated controllers for running HDD/SSD, DVD, tape, USB ports. The "B" models have IVE/HEA which are 10Gb or 1Gb Ethernet. You need to include these in the calculations. You might ignore the DVD and USB as they are generally very small numbers whose peaks (if any) happen at off hours. Likewise the 1Gb Ethernet is small. But If you have integrated 10G E or the Dual RAID SAS options you need to include them in the calculations. Treat the integrated 10Gb Ethernet adapter like a PCIe 10Gb Ethernet adapter with the same number of 10Gb

For a rough guide for the for the integrated Dual RAID controllers: You may be up to a 10 for the integrated pair (not 10 each). The 10 would be if you have some SSD or a lot of HDDs doing large block I/O. Remember that you can attach an #5887 EXP24S to the SAS port on the back of the server and then this same pair of integrated SAS controllers is handling another 24 SAS bays. Increase the sizing factor closer to 10 if running lots

If you are NOT using the "dual" integrated SAS adapter option and using a "single" integrated SAS adapter, use the same performance factor as a #5901 / 5278 SAS adapter with a performance sizing factor or 1-6. For the Power 770/780 you can have two of these single adapters, each with their own sizing factor. If a Power 710/720/730/740/750/755 you would have just one adapter with one sizing factor.

This tool focuses on the total bandwidth available to you. These I/O drawers attach to GX++ Adapters and it is that GX adapter which sets the maximum bandwidth available to all the adapters in that drawer. If you have two I/O drawers on that same GX++ adapter, the two drawers share that same total bandwidth of the GX++ adapter. Having two vs one #5802/5877 provides some redundancy and obviously provides more slots, but does NOT increase max bandwidth. Note that each #5803/5873 is logically two drawers and for higher bandwidth you would cable the drawer to

For this estimator tool, one GX+ bus will support 40 Gb/s and a GX++ bus will support 60 Gb/s. (see Note2 above) GX+/++ buses can "internal" or they can be "external". External GX buses are accessed through a GX slot. All of the external GX slots are GX++ on POWER7 servers except for

Note that some servers share a bus for internal as well as for GX slots. Thus you'll see below times when the total bandwidth is less than the sum

Note the Power 750 has two different GX adapters. The #5609 is GX+ (40Gb) and #5616 is GX++ (60Gb). If a #5609 is placed in the second GX+

1- Look up the sizing factor for each of the adapters. Make sure you know in which PCI slot the adapter(s) will be used.

3- For the subgroups which have internal I/O, also add the sizing factor(s) for the internal I/O

The #EDR1 EXP30 Ultra Drawer attaches to a GX++ PCIe adapter placed in the GX slot of a "D" model 710/720/730/740/750/760/770/780 or a "C" model 770/780. .The #5888 EXP30 Ultra Drawer attaches to a GX++ PCIe adapter placed in the GX slot of a "C" model 710/720/730/740. Inside the Ultra Drawer are two very high performance SAS controllers, more powerful than the #5913/#EAS3. So assume a sizing factor value of 60 for this drawer if a lot of busy SSD. Note each SAS controller has a PCIe cable connecting it to the GX++ PCIe adapter, but the cables can be plugged into different GX++ PCIe adapters. Thus assume a sizing factor of 30 for each cable plugged into the GX slot.The GX++ PCIe adapters are the #EJ03 and #EJ0H.and #1914 #EJ03 plugs into a 720/740. #EJ0H plugs into a 710/730. #1914

This specialized adapter is used only on the Power 710/730 "B" model 8231-E2B to connect to a 4x Infiniband switch in server clustering environments. (On 710/730 "C" models with PCIe Gen2 slots, the QDR PCIe adapter is used instead of this DDR option.) The adapter supports up to a max of 30Gb/s. Actual usage is HIGHLY dependent upon the clustering application. Use a sizing factor of 2 - 30 depending on the

(see also the example just below Power 710/730 B models and the example just below Power 720/740 C

2- Add the maximum sizing factor of each adapter in that subgroup of PCIe slots represented by a separate column in the tables

4- Compare each subgroup's sizing factor total to the subtotal maximum. 4a- If the sizing factor total is less than the subtotal maximum, you easily have adequate bandwidth. 4b- If the total sizing factor total is larger than the subtotal of the column, take action. Review the sizing factors and adjust downward as appropriate. Compare the revised sizing factor total to subgroup maximum.

5- . Then add the subgroups together and compare to the total bandwidth available for the server. If the adapters within a subgroup have a larger total sizing factor than the subgroup maximum, use the smaller value. 5a- If your total of subgroups is less than or equal to the system total, you should have adequate bandwidth. 5b- If your total of subgroups exceeds the system total, see if additional sizing factor adjustments would be helpful and compare again. If the system total is still exceeded, take appropriate action

This tool focuses on aggregate bandwidth with subtotals. The "subtotals" or "subsystem limits" are important. Though individual Gen1 or individual Gen2 PCIe slots are the same, groups of Gen1 PCIe slots or groups of Gen2 PCIe slots sometimes share bandwidth. Bandwidth can also be shared with other internal I/O. The table below lays out the subtotals and the total. If you exceed the bandwidth of a subtotal, for example a GX slot, that means you have a bottleneck which will limit max throughput of the adapters located in that group of PCI slots.

#EJ0H is for #5888 EXP30 Ultra SSD I/O Drawer attach

(See the table just above this row.) In the system unit (internal four slots) you have two 2-port 8Gb Fibre Channel adapters (sizing factor 16) and one 4-port 1Gb Ethernet adapter (sizing factor 0.4-4). (One of the PCIe slots is empty). You have three 177GB SSD in the six SAS bays run by the integrated SAS adapter (sizing factor up to 10) and you have a 2-port 10Gb Ethernet IVE/HEA (sizing factor 10-20 ). In this example the GX slots are not being used. You get the sizing factors from the "PCIe Adapter" worksheet/tab for the PCIe adapters and from the text above for

Example: Power 730 B model continued. Totaling the max sizing factors for these components yield 16+16+4+0+10+20 = 66. (16+16+4+0 = PCIe slots and 10+20 = internal.) 66 is larger than the 40 Gb/s max bandwidth available as shown in column C of the 710/730 B Model table above. So you need to review these number to see if a lower more realistic sizing factor value should be used instead of the 16+16+4+0+10+20 maximums. If after the review and assignment of lower sizing factors you are still above 40Gb/s, you need to move some I/O to the 2nd GX slot in an I/O drawer. Or you could switch to a 730 C model and gain a lot of bandwidth.

In the system unit (internal six slots) you have one 2-port 4Gb Fibre Channel adapter (sizing factor 8) and two 2-port 10Gb FCoE adapters (sizing factor 20 each) and a Async/comm card (sizing factor 0.1-0.2) and one required 4-port 1Gb Ethernet adapter in the C7 slot (sizing factor 0.4-4). (One of the PCIe slots is empty). You have four HDD in the six SAS bays run by the integrated SAS adapters (sizing factor up to 10 - probably less here with HDD). You have two PCIe RAID SAS adapters in a PCIe Riser Card each with four SSD (sizing factor 6 each). Totaling the max sizing factors for thes internal components yield 8+20+20+0.2+0+4+10 = 62.2 (PCIe slots = 8+20+20+0.2+4 and internal = 10.) 62.2 is larger than the 60 Gb/s max bandwidth available for these internal slots so you need to need to analyze the sizing factors to determine if they actually use less bandwidth. Let's assume you do so and

example continued below

Next look at the GX slot size factors of 6+6 = 12. 12 is less than 60 so you are ok on this subtotal. Finally since on the Power 720, there is an overlap of bandwidth between the 1st GX slot and internal slots add all these sizing factors together. "Adjusted 62.2" + 12 is less than 100Gb/s so you fit in the system maximum as well as both subtotal maximums. Your configuration's bandwidth requirements should be ok.

For the extremely analytical reader … Each #5802/5877/5803/5873 PCIe slot subgroup is on its own PCIe 8x PHB. Specifications for this PHB are: BURST = 2 GB/s simplex & 4 GB/s duplex SUSTAINED = 1.6 GB/s simplex & 2.2 GB/s duplex. Most of the time, this level of

Power Systems obtains many PCIe adapters from nonIBM suppliers which leverage technology already created by the PCIe supplier. Sometimes IBM works extensively with PCIe supplier on special functions/capabilities to interface into Power Systems and to comply with standards/structures/interfaces established by Power Systems. Sometimes it is a more modest amount of changes which are made to fit into the Power Systems infrastructure. Very rarely is an adapter brought out by IBM Power Systems with no changes from what the supplier offers generically.

For AIX, IBM i, and VIOS ... For adapters ordered as a Power System feature code, it is IBM who ships the underlying drivers and and it is IBM who provides support of the hardware/software combination. IBM development may work with the PCIe supplier and leverage base supplier driver logic, but IBM is the single point of contact for all support issues from a client perspective. If the problem appears to be related to the PCIe adapter hardware design or manufacturing or by underlying supplier-provided driver logic, IBM support and/or development engineers will work with the adapter supplier if needed.

For Linux... For adapters ordered as a Power System feature code, the drivers used are the generally available, open source drivers for Linux. IBM works with Linux distributors and adapter vendors to help ensure testing of the hardware/software has been done. Support of the hardware/software combination is provided by the organization selected/contracted by the client. That organization could be groups like SUSE, Red Hat, IBM or even client self-supported.

Given the above, usually knowing the specific adapter supplier is of no interest to a client However, occassionlly it is useful to know who IBM worked with to provide PCIe adapters for Power Systems, especially in a Linux enviornment where a user is doing something unusual.
