Expected performance of EVA4400 FATA drives

[Murray Itkin]

We are currently standing up a EVA4400 with 24 1TB FATA drives, as a single group, then split into a four LUNs.

What would you guys(or gals) think we should expect in sequential write performance?

BTW the hosts have 4 8Gb fibre links to the SAN, so the bottle neck will be either the EVA controllers or most likely the FATA disks.

Hi Murray,

1TB can max write 68 IO/Sec. For 24 drives , you would expect to get approx 800 IOPS for Raid1, 400 for Raid5 and 250 for Raid6

That's on the worst case of 100% random writes.

On sequential write you can get 120 MB/s in RAID 1 and 192 MB/s on RAID 5 and 6.
