© 2010 IBM Corporation IBM Confidential 12 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 Duplicate Your Data across nodes NETWORK RAID P4000 relies on redundant hardware resources to provide data protection Ex: P drives per node HW RAID 10, 5, 6 Two HP P4000 Nodes are two HP Servers This is NOT a dual storage controller !!! This is 2 nodes each a SPOF Two HP P4000 Node are two HP Servers with SAN/iQ software This is NOT a dual storage controller !!! Network RAID software is used to create another copy of data (2x space) This is 2 nodes with high availability

© 2010 IBM Corporation IBM Confidential 13 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: Disk model: 2 sets 5+1 RAID 6 8 Disk model: 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 Mirror data with Network RAID Across nodes HARDWARE RAID 10, 5, 6

© 2010 IBM Corporation IBM Confidential 16 HP P4000s 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 P SAN/iQ Storage Node Synchronous Mirroring

© 2010 IBM Corporation IBM Confidential 17 Overcoming A SPOF But At A Price P4000 touts mirroring as a strength… because they must –P4000 doesnt provide disk access between servers –P4000 doesnt 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 P SAN/IQ Storage Node Synchronous Mirroring

© 2010 IBM Corporation IBM Confidential 18 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 cant communicate with the outside world then storage must shut down and local apps crash P SAN/IQ Storage Node Synchronous Mirroring

© 2010 IBM Corporation IBM Confidential 19 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 P SAN/IQ Storage Node Synchronous Mirroring P SAN/IQ Storage Node P SAN/IQ Storage Node P SAN/IQ Storage Node

© 2010 IBM Corporation IBM Confidential 21 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 NETWORK RAID 5 & RAID 6 SAN/iQ Cluster A E C F P2P2 B P1P1 D K P4P4 J L P3P3 I G H Network RAID 5 SAN/iQ Cluster A G C H P2P2 B P2P2 O M N P P3P3 P3P3 I J D E P1P1 F P4P4 P4P4 K L P1P1 Network RAID 6 NEW
