For what it's worth, I configured a T5220 this week with a 6 disk, three
mirror zpool. (three top level mirror vdevs...).
Used only internal disks...
When pushing to disk, I was seeing bursts of 70 odd MB/s per spindle,
with all 6 spindles making the 70MB/s, so 350MB/s ish.
Read performance
We¹re looking at building out sever ZFS servers, and are considering an x86
platform vs a Sun 5520 as the base platform. Any comments from the floor on
comparative performance as a ZFS server? We¹d be using the LSI 3801
controllers in either case.
