Solaris Operating System - Get Solaris 10
I haven't looked at Solaris in a while, but apparently, it's free.
Snaggin' it now for VM goodness. Anyone fiddle with it?
Solaris 10 has been free for a looong time I have a boxed copy that they will send you if you ask. I run it in a VM sometimes, not a bad OS. Obviously I haven't tried it in a datacenter environment though.
