EVA3000 and MA8000 IOPS

[Cass Witkowski]

We did some testing with HSG80s and EVA3000.

The HSG80s had 32 9 GB 15K rpm disks each one was a set up as a JBOD with no cache enabled. (no read, no writeback and no read-ahead). We used TESTDEV on OpenVMS system. We did random 1KB reads on the disks. The maxium we could get through the HSG80 pair was about 4,700s I/O per second. Since this was with cache turned off this was I/Os from the disks.

On the EVA we had 48 36 GB disks which we created 32 vraid 0 disk of 9 GB in size. We ran the test and got over 30,000 I/Os per second. Again cache was disabled.

On a MSA1000 we did a similar test and saw about 10,000 I/Os per second

YMMV
