Family Information

HP StorageWorks P2000 G3 Modular Smart Array Systems

LUNs

The HP StorageWorks 2000 family of arrays supports 512 LUNs (total volumes in a dual controller

 

system) and LUN sizes up to 16 TB. The array supports expansion and deletion of any LUN.

RAID 0, 1, 3, 5, 6, 10,

In addition to the usual RAID levels, the P2000 G3 features several important additional levels.

50

RAID 6 is the highest level of RAID protection. It allocates two sets of parity data across drives and

 

allows simultaneous write operations. It can withstand two simultaneous drive failures without

 

downtime or data loss. RAID 10 is mirroring and striping without parity. It is the most popular of the

 

multiple RAID levels, allowing large arrays with high performance in most cases and superior fault

 

tolerance. RAID 50 combines the block striping and parity of RAID 5 with the straight block striping

 

of RAID 0, yielding higher performance than RAID 5 through the addition of RAID 0, particularly

 

during writes.

 

 

 

 

 

 

Performance

Performance numbers are a guideline as established by tests using RAW I/O in an Operating

 

System Agnostic test lab environment. 144 GB 15K SAS drives were used in a dual controller

 

configuration of 12 vdisks consisting of twelve disks per vdisk, 1.6 TB volumes, and 3 volumes per

 

host. 4 hosts directly attached to the P2000 G3 array were used in this test configuration (results

 

cannot be expected with a single host). Results were achieved in Sequential Writes with 256K

 

blocks; all random tests were based on 8K block sizes.

 

 

 

 

NOTE: Number and type of applications, drive type and number of drives, operating system used,

 

and the number of hosts will affect overall performance. This table is provided strictly as a test-lab

 

comparison. Note: These numbers reflect a full array configuration with the maximum number of

 

front-end ports, disks, and controllers. The test results shown for the P2000 G3 are preliminary and

 

designed to give a reference point for comparisons. They will be reposted shortly when finalized.

DC-power chassis

HP is making the two models of controller-less chassis available with direct current (DC) power

 

supplies. They each have the two empty bays where users can insert one or two P2000 G3

 

controller(s). In addition, the P2000 chassis with LFF drive bay can have P2000 3.5-inch I/O

 

modules inserted to create a LFF DC-power JBOD.

 

 

 

 

The 500 watt power supply is designed to operate over the input range of -40VDC to -75VDC.
