I have a T-series box with 4 internal drives and would like to deploy ZFS with availability and performance in mind.... ;) What would some recommended configurations be? Example: use internal RAID controller to mirror boot drives, and ZFS the other 2? Can I create one pool with the 3 or 4 drives, install Solaris, and use this pool for other apps? Also, what happens if a drive fails?
Peter Tribble's approach is nice, but old fashioned. By partitioning the first two drives, you can arrange to have a small zfs-boot mirrored pool on the first two drives, and then create a second pool as two mirror pairs, or four drives in a raidz to support your data. The root pool needs to be large enough to deal with whatever you plan to throw at it, such as multiple boot environments via live upgrade and backout patches. It will steal a bit of space from the other drives but this is not usually much cost given today's large drives.
You can use zfs for all of this. It is not necessary to use something antique like SVM.
The other approach (already suggested by someone else) is to figure out how to add another device just for the root pool.
