Solaris 11 GA was released November 2011, i.e. (11/11) and has no problem
booting from the various RAIDZ types. And, a ZFS rpool is all it will
I'm not sure if this is a big deal or not. Maybe a bigger deal for the SOHO end

Solaris 11 GA runs only on T-series or M-series boxes. All those nice, but
aging, Ultra III and Ultra IV boxes had support dropped out from under them.
Solaris 11 Express - for my personal use - All the new Solaris 11 goodies and
