Gaaah, no idea what happened to that. It looked ok in preview, but it seems
the message board is adding odd characters to my text. Trying again:
RAID-Z2
Disks per setSetsWrite PerformanceRead PerformanceRead IOPS
46...1...44...1...
There are *lots* of options for configuring a Thumper, what you choose really
depends on the kind of performance you want. I found these sites incredibly
helpful in working out what was best for us:

That's a handy feature. I've added a couple of such comparisons:

We're deploying a new Thumper w/750GB drives, and did space vs performance

Also filebench:

You'll see the most difference between 5x9 and 9x5 in small random reads:

Depending on needs for space vs. performance, I'd probably pixk eithr
5*9 or 9*5, with 1 hot spare.

The server come with Solaris install on two disk. That's mean I've got 46

When I look the defautl configuration of the zpool
zpool create -f zpool1 raidz c0t0d0 c1t0d0 c4t0d0 c6t0d0 c7t0d0
zpool add -f zpool1 raidz c0t1d0 c1t1d0 c4t1d
