Err...
Entry level is: "16-core processor running at 1.65GHz with 16GB of memory and a single 300GB disk"
A single disk? Not a mirror? Oodles of processor power, oodles of RAM, Solaris, but only one disk to run it from? Surely no disk (boot from SAN) and dual disk for mirroring would have been more sensible options otherwise why bother with a rock solid OS when it's not running on redundant disks?
