5). For MSA 2040 Hard Disk Drive (HDD) results, 146 GB 15K SAS drives were used in a dual controller
configuration of 16 vdisks consisting of twelve disks per vdisk, 1.6 TB volumes, and 4 volumes per host. 4
hosts directly attached to the HP MSA 2040 array were used in this test configuration (results cannot be
expected with a single host).
NOTE:
MSA 2040 tests with 1GbE iSCSI used 8 hosts directly attached to the HP MSA 2040 array.
6). For MSA 2040 Solid State Drives (SSD) results, 200 GB Enterprise Mainstream SSDs were used in a dual
controller configuration of 4 vdisks consisting of two disks per vdisk, 200 GB volumes, and 1 volume per
host. 4 hosts directly attached to the HP MSA 2040 array were used in this test configuration (results cannot
be expected with a single host).
NOTE: MSA 2040 tests with 1GbE iSCSI used 8 hosts directly attached to the HP MSA 2040 array.
7). Sequential tests results were achieved with 256K block sizes and random tests were based on 8K block
sizes.
NOTE:
For sequential workloads with a queue depth greater than 1, each sequential stream is targeted to
operate on a separate LBA range. Other types of sequential workloads that target specific LBA ranges may
achieve higher results
8). All SAS results were measured using 6Gb SAS Host Bus Adapters.
9). All Fibre Channel results were measured using 16Gb FC Host Bus Adapters. All SAS results were
measured using 6Gb SAS Host Bus Adapters. All 10GbE iSCSI results were measured using 10GbE iSCSI Host
Bus Adapters. All 1GbE iSCSI results were measured using 1GbE network interface controllers (NICs).
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 HP MSA 2040 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 MSA 2040 controller(s).
The 500 watt power supply is designed to operate over the input range of -40VDC to -75VDC.

(Will accept one or two MSA 2040 SAN or MSA 2040 SAS controllers and can
accommodate up to twenty four 2.5-in (SFF) drives)
