How long's a piece of string?
I can tell you what my production systems look like: there's a small (24G or
so) partition on s0, some swap, and then the rest of the space on s7.
Then mirror the first 2 disks slice 0 using SVM (this configuration was devised
before ZFS boot) for the OS; mirror slice 0 on the other two disks for an
alternate root for Live Upgrade.
Then create a couple of mirror vdevs using the remaining space.
So SVM looks like:
d10 -m d11 d12 1
d11 1 1 c1t2d0s0
d12 1 1 c1t3d0s0
d0 -m d1 d2 1
d1 1 1 c1t0d0s0
d2 1 1 c1t1d0s0
and ZFS looks like:
NAME STATE READ WRITE CKSUM
storage ONLINE 0 0 0
mirror ONLINE 0 0 0
c1t0d0s7 ONLINE 0 0 0
c1t1d0s7 ONLINE 0 0 0
mirror ONLINE 0 0 0
c1t2d0s7 ONLINE 0 0 0
c1t3d0s7 ONLINE 0 0 0

Swap it for a new one ;-)
(somewhat more complex with the dual layout as I described it).
