Key Messages to Keep in Mind – The Devil is in the Detail !

Vendor marketing materials and presentations sound great– Such material is high level by definition– It is designed to highlight a product's strengths– Claims of advanced design, high availability, superior performance, low cost, are common

BUT

Potentially significant system differences despite similar names: – Virtualization – Clustering – Tiering – Storage Pooling – Copy Services– Consistency Groups

Some system differences will be visible to customers

Customers need to understand “delivered” capability

There is no Industry Standard for Feature and Function Names

P4000 Storage Nodes are HP Servers

P4000 uses HP Servers as Storage Nodes – Two basic HP Server choices – P4300 or P4500– Nothing is modified on HP Servers

• Redundant fans • Redundant power supplies • Redundant NICs cards• Hardware RAID for disks

– Dual RAID controller w/battery-backed 1GB cache

P4000 Offering Packaging– One P4300 or P4500 package = Two Nodes – Hence P4300 has 2 x 8 disk drives = 16 disks

• Scales from 16 to 256 drives– Hence P4500 has 2 x 12 disk drives = 24 disks

• Scales from 24 to 384 drives – Optional one node P4300 or P4500 expansion– Refreshes occur with new server releases

P4000 uses latest HP ProLiant Technology


IBM Confidential

Why does HP P4000 Become so Expensive!!

One HP P4000 Node is a single HP Server

This is NOT a dual storage controller !!!

This single node

is a SPOF

HW RAID 10, 5, 6

HW RAID 10, 5, 6

HW RAID 10, 5, 6

HW RAID 10, 5, 6

Duplicate Your Data across nodesNETWORK

RAID

P4000 relies on redundant hardware resources to provide data protection

Ex: P4300 8-drives per node

HW RAID 10, 5, 6

Two HP P4000 Nodes are two HP Servers


This is 2 nodes

each a SPOF

Two HP P4000 Node are two HP Servers with SAN/iQ

software


Network RAID software is used to create another copy

of data (2x space)

This is 2 nodes with high availability


IBM Confidential

High Cost of Data Protection – Must use two RAID Levels!

Internal Hardware RAID only protects HDD failures

To provide High Availability customer MUST mirror (Network RAID) multiple copies of data across a cluster of storage nodes

ASSOCIATED Network RAID overhead also reduces usable bandwidth

Spares required in each node

Hardware RAID for disks can be selected during initial setup of a node and cannot be changed once the node is added to a cluster

HENCE increasing costs and lowering usable capacity dramatically

Available Internal Hardware RAID levels

• RAID 5

− 8 Disk model: 7+1 − 12 Disk model: 2 sets 5+1

• RAID 6

− 8 Disk model: 6+2 − 12 Disk model: 2 sets 4+2

• RAID 10

− 8 Disk model: 4 drives striped and mirrored to 4 drives

− 12 Disk model: 6 drives striped and mirrored to 6 drives

HP P4000’s Network RAID Definition

How Network RAID works:

– Creates redundant copies of data blocks

– That resides on different storage nodes

– Can specify up to four (4) copies of data

– Recommended/default –2-way network RAID

Sell 2x copies of data as Disaster Recovery Solution

P4000 + SAN/iQ P4000 + SAN/iQ

SynchronousMirroring


IBM Confidential

Overcoming A SPOF But At A Price

P4000 touts mirroring as a strength… because they must

– P4000 doesn’t provide disk access between servers

– P4000 doesn’t provide internal info between servers

– A minimum of 2 systems are required for redundancy

– Volumes (LUNs) are only seen by local Storage Node

Data availability beyond hardware RAID … because they must

– Network RAID = redundant copies of data (2x) i.e. mirroring

– Option to do 1, 2, 3 or 4 redundant copies

Requires approx 2X the disks of competing systems to try to equal their performance & availability

P4000 + SAN/IQ P4000 + SAN/IQ


SynchronousMirroring


IBM Confidential

Beware Of Campus-wide SAN Argument

P4000 encourages customers to divide their storage between buildings

They tout BC/DR… because it appears to play to their strength

The problem is; if the comm-link is down, or a building is down, or a controller is having a firmware upgrade, then a single controller failure can corrupt parts of all live volumes

If a building can’t communicate with the outside world then storage must shut down and local apps crash

P4000 + SAN/IQ P4000 + SAN/IQ

Mirroring


IBM Confidential

Campus SAN Costs Can Soar Best practices require doubling the hardware for performance to avoid local reads

over the WAN

P4000 encourages 4-way replication - This way if the connections between buildings go down there is no single point of failure

This makes a P4000 solution tremendously expensive

Conclusion: Individual Prices look low vs Real World Business Requirements


IBM Confidential

Network RAID 5

Delivers approximately 60% utilization of raw disk capacity

Requires at least 4 nodes in a cluster

Recommended for use with mostly read, sequential applications such as file shares and archives

Network RAID 6 Delivers approximately 55% utilization of raw disk capacity

Requires at least 6 nodes in a cluster

Recommended for use with mostly read, sequential applications such as file shares and archives on larger P4000 clusters

HP BEST Practices: HP STILL RECOMMENDS NETWORK RAID 10!!

Network RAID 10 is the default protection level as it has the best balance of performance and protection and it is recommended for use with any applications

Only Network RAID 10, 10+1, and 10+2 provide protection from site failures in a multi-site SAN configuration

HP P4000 Take-Always

Use latest Industry Standard Components – server hardwareUse latest Industry Standard Components – server hardware– Low-cost entry point– Virtualization & Storage Pooling– Thin Provisioning & Snapshot– Disaster Recovery is included– All-inclusive bundled software

Network RAID is positioned as a selling advantage, is greatly flawed

Requires approximately 2X the assets of competing storage in order to even try to equal performance and availability

If TCO is important, & remote mirroring isn’t required, then P4000 is not for you

P4000 requires more; drives, labor, and expertise to meet business needs
