We ended up putting a couple extra SATA disks in to hold the OS, and decided to
forgo the L2ARC for now, so the SSDs are only for the ZIL, and mirrored for
fault tolerance:
zpool create data raidz c0t4d0 c0t5d0 c0t6d0 c0t7d0 log mirror c2d1 c3d1
# zpool status data
pool: data
state: ONLINE
scrub: none requested
config:
NAME STATE READ WRITE CKSUM
data ONLINE 0 0 0
raidz1 ONLINE 0 0 0
c0t4d0 ONLINE 0 0 0
c0t5d0 ONLINE 0 0 0
c0t6d0 ONLINE 0 0 0
c0t7d0 ONLINE 0 0 0
logs ONLINE 0 0 0
mirror ONLINE 0 0 0
c2d1 ONLINE 0 0 0
c3d1 ONLINE 0 0 0
We'll be beating on this for a few days and then we'll have a better idea how it
works.
