HP Midrange EVA - Strengths

Easy to manage (when everything is working correctly)

Supports 4Gb/s host ports

iSCSI option (through Gateway)

NAS option (through Gateway)

Support wide assortment of Operating Systems

One drive enclosure used for three drive types

Solid State Drives – 72 GB (min of 6, max of 8)



HP Midrange EVA - Weaknesses

Limited flexibility and tuning due to current virtualization scheme

Management software required (separately priced)

Hardware packaging

– Expansion units hold maximum of 12 drives

– No SATA support for EVA

Lacks real world performance

– Will not submit SPC-1 benchmarks (IOPS) for EVA8x00 series

– IBM DS5000 delivers nearly 4x the SPC-2 (MB/s) of the EVA8x00

Very difficult to achieve HA configurations without big money

– Redundancy at drive enclosure level is difficult to achieve



HP MSA2000



Competing Against HPQ’s MSA2000

Basic System & Strengths MSA2000fc (fibre channel) & MSA2000i (iSCSI) SAS/SATA (intermixing within drive enclosure) Up to 48 drives (option for up to 99 drives for fc based

controller) 1GB Cache per controller RAID 0, 1, 3, 5, 6, 10, 50 Greater than 2TB LUNs Optional

– Snapshots (8 standard, upsell to 64 per system)– Clones

Should exceed performance of previous MSA systems

MSA2000i starting ~ $4,999; MSA2000fc ~ $5,999 (probably 1 controller w/o drives)

Install base of MSA systems = 120,000 per 451 group 3-4-08

Weaknesses Different Drive carriers than

HP’s SAS servers Does not yet support 1TB SATA

drives Does not share storage

management platform with EVA No UNIX support but HP-UX No SPC- or SPC-2 benchmarks SW warranty 90 days only



DS3000 vs HP low end offerings



Areas to focus on with HP

Software pricing

– Understand the terms and pricing for on-going support

Why no industry standard benchmarks?

– Only paper on the web is an internal test of SAS/SATA drives

Why no Solaris or AIX support?

Why is warranty different for SAS versus SATA drives?



What To Anticipate From HP Heterogeneous storage virtualization

– HP has announced the introduction of Heterogenous Virtualization for 2009

– Will enable them to virtualize multiple EVAs in one system

– Will enable them to virtualize competing systems

• Combat this ability with proven success of SVC

Constant pressure regarding the EVA’s ease-of-use

– Combat this by discussing their numerous restrictions

– Combat this by pointing out their difficulties when things aren’t running perfectly on the EVA

Statements that the EVA has tremendous disk utilization via their internal virtualization process

– Combat this with EMC’s capacity documentation along with pointing out the inefficiencies of HP’s internal virtualization process



Top 3 Takeaways For HP

IBM, not HP, has management that is easy to use but more importantly is also full-featured. IBM systems allow easy capacity upgrades and easy maintenance

IBM DS5000 storage, unlike HP EVA storage, provides maximum amounts of useable capacity. HP EVA’s much like NetApp FAS systems have poor useable capacity.

IBM, not HP, provides balanced levels of storage scaling & performance making them the best storage systems for corporate data-consolidation programs

CLARiiON architectural limitations

What happens in case of a failure in one of the first five disks?

1. All write-caching disabled

2. The system goes into slow motion

3. Hot spare build up, worsens performance

4. The failed drive must be replaced

5. The failed drive must be fully rebuilt



EMC Adopts IBM’s ‘Flat’ Pricing Model

CLARiiON CX4 software pricing has been greatly simplified to make the new CLARiiON series more sales-friendly. All the software titles are priced using a consistent, single-price-per-array model.

Due to the elimination of the Navisphere enterprise tier, Navisphere Analyzer is now sold stand-alone with a single price per array.

Note: RecoverPoint/SE CRR, CLR, and CDP products are limited to a specific amount of replicated capacity, either within the same array or between two CLARiiON arrays—one at each site.

– EMC/Dell – 8TB License

– EMC – 4TB, 8TB or 16TB License

EMC CLARiiON CX4 Software Ordering Information and Configuration GuidelinesJuly 17, 2008



EMC’s CX4 Value Propositions

Take cost out of the business without sacrificing performance and scalability by consolidating twice the workload in a single system—optimizing storage capacity—and by protecting investments – DS5000 performance is superior in limited benchmarks

The CLARiiON CX4 series’ power-saving technologies help manage energy consumption and consolidate data storage. – DS5000 benchmarks reflect greater storage efficiency SPC-1 and SPC-2, therefore less energy. Intermix capability in enclosures yields redundancy with half the enclosures

CLARiiON CX4 systems provide industry-leading availability and protection by combining CLARiiON’s proven Five 9s availability with built-in support for concurrent local and remote (CLR) replication – DS5000 does suffer from Clarion issues of Write Cache Disablement and back end loss due to device failures (Known Clarion problems)

CLARiiON’s unique hardware and software capabilities and integration with VMware extends the value of virtualized server environments – VMWare is vendor neutral and IBM has strongly promoted VMWare. DS3000 AND DS5000 support VMWare

Dell/EMC AX4



Dell / EMC AX4

AX4 Strengths FC and iSCSI versions available Single or dual controllers Supports Windows, Linux, and VMWare Can be controlled by Navisphere rather than just

Navisphere Express Support for up to 64 hosts and 60 drives (SAS or SATA)

AX4 Weaknesses Dell has slashed prices recently, but still over

$9000 for base unit Does not support:

► SAS drives without additional licensing► Expansion Units without additional licensing► more than 10 hosts without additional

licensing► More than 16 total Snapshots, no more than

1 per LUN► array-based clones



DS3000 Competitive Attack Points against Dell/EMC

IBM Product Capability Dell/EMC

DS3000 offers both SAS and SATA drivesAX4 offers both SAS and SATA drives – requires additional licenses to support SAS drives ($$$)

SAS, iSCSI and FC host attachmentsiSCSI and FC only (no SAS host attachment)

DS3000 can scale up to 48 drives

AX4 scales up to 60 drives

AX4 requires additional licenses to connect to more than 10 hosts.

DS3000 performance is publishedNo 3rd party performance benchmarks available for AX4

2U packaging UPS required (additional 1U)

Attractively priced – 3 year warranty Check the warranty – is it the same?



Areas to focus on with EMC

Software pricing

– Understand the terms and pricing for on-going support

Remote mirroring

– What is the cost in terms of host performance?

– What happens to multi-pathing support?

How many drives are needed?

– Do you really need 60 drives?

– Will the processors deliver scalable performance?

Why no industry standard benchmarks?

– Only paper on the web is an internal test of SAS/SATA drives

Is VMware part of your future?



DS3000 vs Dell low end Storage



DS3000 vs EMC offerings



Competing Against EMC Assure Factual / Actual Comparisons

– Again: Review SPC Benchmarks with your customer • Focus your customer on EMC’s lack of public benchmark participation

– Provide reference accounts from the Customer Reference DB.– Encourage your customer to thoroughly check all references from all vendors

Back to Basics: meet customer’s business needs with a total solution– Bundle with Server and Tape when the customer’s requirements dictate

• “When IBM bundles storage with servers, you lose” .. From EMC salesbook – Clothe hardware with software and services – Combine with SVC wherever possible– Team with Solution Providers (ISPs)– Finance with IGF– Sell TCO advantages

• Do a 3-5yr TCO analysis comparison: uncover the hidden EMC re-occurring costs

Show IBM’s products as committed to SMIS open standards, and together with SVC will provide the customer with both device and vendor independence



Top 3 Takeaways For EMC

IBM, not EMC, is the only vendor who has publicly proven the ability of their storage systems to handle high-performance VMware mixed workloads

IBM, not EMC, provides balanced levels of storage scaling & performance making them the best storage systems for corporate data-consolidation programs

IBM, unlike EMC, supports all facets of a solution:

– Low-cost heterogeneous storage virtualization

– High-performance storage

– Global service & support

– Tape systems

– Software

– Servers



Final Thoughts:Selling Against Mid-Range/Entry Competition



Selling against Competition

DS3K/4K/5K technical leadership– SPC-1 and SPC-2

benchmarks to demonstrate the IBM performance advantage

– SAN-wide virtualization– Dedicated storage ASIC– Dedicated data cache

DS3K/4K/5K TCO advantages– 1 year / 3 year warranty on HW and SW Storage

Manager included•Competitors charge for on-going SW support!!!

– Multi-path capabilities included– Maximizes useable capacity– Customer installation and Set-up

DS3K/4K/5K flexibilities– DACstore data-in-place update– Ease of Configuration

Dynamic features



The Mid-Range Disk Marketplace is driven by:

– Price Sensitivity: All things being equal, they want to buy disk “on the cheap”

– Performance: They are as demanding as enterprise class customers that their applications get the best performance possible. The mid-range marketplace is where the major portion of the industry’s data explosion is happening.

– Reliability: Same as Performance. Their critical applications can not take a hit

– Interoperability with existing I/T environment:. The Mid-Range customer desires not to turn over his inventory with any degree of frequency as he adds capacity to match the explosive demand for data.

– Latest Features: Just about all the product features that mainframe customers have become accustomed to, is now needed by their mid-range counterparts

– Support and Service: They have become dependent on the vendors today. We must not let them down.

Mid-Range

These are the major purchase criteria for products in the Mid-Range



DS4000/DS5000 Attributes (20% of Criteria):

– Lower TCO• DACStore • DS5000 Storage Manager • Dynamic features

– Validated with Brocade (McData), and Cisco SANs

– Fastest performance, 4Gb FCP on select models

Mid-Range

IBM DS4000 / DS5000 meets the Mid-Market Purchase Criteria

Vendor / Wrapper Attributes (80% of criteria):

– IBM Service Alert “call-home”

– Implementation services

– Training and Education (on-site and off-site)

– IBM offers “one stop shopping” for complete solutions (servers + storage + software + services + financing)

– System Storage Proven™ certification program

– IBM is the leader in storage virtualization

– Integration with IBM servers and software

• Integrated Backup for Devices (IBD)

– Access to IBM and LSI Logic experts



You can position HP EVA vs DS5000 as follows:

– HP has not published any public benchmarks. What are they hiding?

• IBM performance is measured, not just an estimate

– 8400 requires HP to install, setup. IBM DS5000 is customer setup. Which indicates simplicity?

– Software pricing – what is free, what is billable, are there on-going costs?

Mid-Range

Use The IBM Competitive Strengths Against Competition’s Weakness



You can position EMC CX4-Series vs DS5000 as follows:

– EMC refuses to participate in any public benchmarks. What are they hiding?

– CX4 models are slower than similar DS5000 systems, especially for larger configurations

– CX4 software is priced just like the DS5000 (flat priced software)

Mid-Range




You can position DS3000 vs. HP MSA as follows:

► Consistent warranty terms – not focused at the part level

► Performance benchmarks – IBM participates

HP Claims for EVA Storage Systems

Ease of management

Intuitive user interface

High performance, high capacity and high availability

Solution saves time, space and management costs



EVAs Aren’t Easy To Manage If Anything Goes Awry

Automatic isn’t always automatic

– If the storage system contains disk drives of different capacities, the SSSU procedures used do not guarantee that disk drives of the same capacity will be exclusively added to the same disk group. If you need to restore an array configuration that contains disks of different sizes and types, you must manually recreate these disk groups. The controller software and the utility’s CAPTURE CONFIGURATION command are not designed to automatically restore this type of configuration.

• EMC performed capacity examinations to demonstrate the tremendous disparity between useable capacity in various storage systems

• EMC examined themselves, HP EVA and NetApp FAS systems

• IBM DS4000/DS5000 were not examined

• Observing EMC’s approach it is clear IBM systems would meet or beat the useable capacity of EMC CLARiiON systems

EVA Availability Is Subject To The Rule Of 8

A Virtual Disk Pool (VDP) can be as large as the entire storage system but cannot be any smaller than 8 drives in size

– Best Practices say “Should only have 1 VDP”

– If FC & FATA disks are used there must be at least two VDPs

– If databases are involved there must be multiple VDPs• To put Log Files into their own group you must create an 8-drive pool &

use 2 disks

Redundant Storage Sets (RSS) can be as small as 6 drives & as large as 11 drives but they always try to “lock in” at 8 drives

To achieve redundancy at the enclosure level, under RAID 5, an EVA must have 8 drive enclosures.

– An enclosure failure with fewer than eight drive trays will likely result in complete loss of data availability



EVAs Are Tricky To Configure

HP limits what customers can do themselves

– “Installation of the Enterprise Virtual Array should be done only by an HP authorized representative.”


There is nothing wrong with this, but it is evidence that

EVAs are not the super easy systems they are often

claimed to be

HP Recommends Only One Drive Type & Capacity

HP recommends using the same drive type (the same capacity) within a disk group because virtualization allocates space proportionate to the highest capacity drive within the group.

– FATA drives are designed for lower duty cycle applications such as near on-line data replication for back-up. These drives should not be used as a replacement for EVA's high performance, standard duty cycle, Fibre Channel drives. Doing so could shorten the life of the drive.

– A minimum of eight FATA drives are required in a configuration.

– Solid State Drives must be in a separate disk group




Maintaining HA In EVAs Requires A Lot Of Attention

Adding disk drives is not a simple matter like it is with DS5000

– Guidelines for adding disk drives

• When adding new disk drives to the storage system, you should ensure that the disk drives are installed in the correct positions to maintain availability (Rule of Eight coming into play)

• The disk drives should be distributed evenly across the disk enclosures. The number of disks a given type in each enclosure should not differ by more than one. For example, no enclosure should have two disks until all the other enclosures have at least one.

• Disk drives should be installed in vertical columns within the disk enclosures. Add drives in multiples of eight, completely filling columns if possible. Disk groups are more robust with the same number of disk drives in each enclosure.

What We Might Say About CX4 Value Proposition #1

Take cost out of the business without sacrificing performance and scalability by consolidating twice the workload in a single system—optimizing storage capacity—and by protecting investments.

This is everyone’s intention. The real question is whether they can achieve the objective with their new CX4 hardware and software. The DS5000 series clearly demonstrates the ability to handle massive workloads. Public benchmarks have taken guessing out of the equation and replaced it with fact.

– DS5000 series have demonstrated the ability to deliver balanced performance (IOPS & MB/s) for use in consolidating mixed workloads like Exchange, Oracle, SAP, SQL, VMware and others.

– DS5000 does more…with less. A better TCO with a faster ROI




The CLARiiON CX4 series’ power-saving technologies help manage energy consumption and consolidate data storage.

Once again this is the objective that everyone is attempting to deliver. EMC has produced some nice tools but an examination of their systems help indicate they will likely cost their users more money in energy costs than systems from IBM

– IBM has greater storage efficiency (drive/controller performance)

• Proven with SPC-1 (IOPS) and SPC-2 (MB/s) results

• Doing more with fewer storage assets = lower energy use

– IBM allows drive intermixing within enclosures, thus enabling fully redundant configurations with ½ the enclosures

– IBM carries this same green message to servers for a total solution




CLARiiON CX4 systems provide industry-leading availability and protection by combining CLARiiON’s proven Five 9s availability with built-in support for concurrent local and remote (CLR) replication.

This is clearly a strong thrust in EMC’s message and should be considered by anyone seeking maximum protection. However, this is the same message carried by IBM, HDS, HP and others. At this level of competition everyone is declaring Five 9s of availability and careful implementations will deliver that.

– DS5000 does not suffer from issues like…

• “Write Cache Disablement” due to a failed drive in the first enclosure

• “Write Cache Disablement” due to a failed power supply

• Loss of back-end due to unexpected loss of a FC loop




CLARiiON’s unique hardware and software capabilities and integration with VMware extends the value of virtualized server environments.

VMware is the EMC buzzword. There are many users who have yet to implement VMware, but there are numerous users who have. This is an area of increasing importance and one in which IBM has assumed a leadership position.

– IBM is, and has been, one of the largest promoters of VMware.

– IBM DS3000, DS4000 & now DS5000 are supported by VMware

– IBM recently won a 2500 unit order based around VMware support

– IBM Enhanced Remote Mirroring with Site Recovery Manager solution

CLARiiON CX4s Still Can’t Intermix Drives

CX4 drive enclosures support the following 4Gb/s drives:

SATA drives can’t be mixed with FC drives, because of issues with rotational vibration.

New 7,200 rpm SATA drives can be placed in the same drive enclosure with older 7k SATA drives,

5,400 rpm SATA drives can’t be mixed with 7k SATA drives.

Some Things About EMC’s RAID 6 To Remember

• Requires FLARE 26• Based on EVENODD algorithm• EMC claims it does not require recursive computations

Limitations: RAID group expansion (adding new disks to an existing RAID group) is

not supported. RAID group defragmentation is not supported. CLARiiON performance testing done with CX3-80 & FC disk drives EMC reports rebuild time for RAID 6 ~ 10% longer than for RAID 5 EMC reports that “RAID 6 has a disadvantage to RAID 5 and RAID 1/0 for

small, random writes and system write bandwidth performance, but other I/O profiles are not affected as significantly.

Besides “small random writes” (IOPS) & “system write bandwidth” (MB/s)… What else is there?
