zpool get cachefile _pool_name_ if it says default, I think it will actually be the value you'd see if you look at grep ZPOOL_CACHE /usr/include/sys/fs/zfs.h which should work out to /etc/zfs/zpool.cache (on Solaris - maybe /boot/zfs/zpool.cache on FreeBSD and/or MacOS?) It'd be better if you had root mirrored, and raidz or raidz2 (or a concatenation of mirrors, if you need max write performance) for the rest. Best I leave it to someone that knows what the installer can support along those lines to suggest a particular layout strategy.
