I've seen very good performance on streaming large files to ZFS
on a T2000. We have been looking at using the T2000 as a disk
storage unit for backups. I've been able to push over 500MB/s to
the disks. Setup is EMC Clariion CX3 with 84 500GB SATA drives
connected w/ 4Gbps all the way to the disk shelves. The 84
drives are presented as raw luns to the T2000 -- no HW RAID
enabled on the Clariion. The problem we've seen comes when
enabling compression, as that is single threaded per zpool.
Enabling compression drops our throughput to 12-15MB/s per pool.
This is bugid: 6460622, the fix is apparently set to be put back
into Nevada fairly soon.
This was just putback and will be in snv_59.
enjoy your unconstrained compressed I/O,

Awesome, thank you.
I almost hate to ask, but... Is there any way to track when the
fix will make its way back into Solaris 10 via update4(?) or a patch?
we're gonna try and squeeze it into s10u4, no guarantees just yet
though. If it makes it, i'll update the list...
