While reading through the documentation for the HP Storage Works 2000 MSA, I found the following performance numbers cited in the quickspecs for both the FC and SAS versions. The 2000fc version cited performance numbers for the fc (Fiber Channel), sa (SAS) and i (iSCSI) models. The 2000sa version only cites SAS results. The MSA 2000 Technical Cookbook also cites performance results.
The results cited in the FC model cannot be correct, unless the SAS and iSCSI models were completely botched, and as far as I am aware of, it has been a really long time since HP/Compaq last botched a design this badly.
I am inclined to think that the results cited in the FC section are incorrect, and may inadvertently be used by HP sales rep to recommend the FC version. Of course, for Data Warehouse applications, I would still recommend the direct-attach MSA-60 and skip the SAN.

| Performance | Performance numbers are
a guideline as established by tests using RAW I/O in an Operating System
Agnostic test lab environment. A total of 96 72GB 15K SAS drives were used
in a dual controller configuration of eight 12 Disk vdisks, eight 806 GB
volumes, and two volumes per host. Four hosts directly attached to the
MSA2000fc G2 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. Number and type of applications, drive type, operating system used, and the number of hosts will affect overall performance. |
