[Sunhelp] RAID and other Disk questions

[Magnus Abrante]

Depends on how much storage you want.

If we look at Sun hardware, we have the A1000, A3000, A3500 and the 
newest family member; T3.. See also http://www.sun.com/storage/ .

About stress tests; not to sure, but i think you want to stress test
the application running on them, there are a few of those programs,
even if i can't remember their name right now.
