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 designed to give a conservative reference
point for comparisons.

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.
