We use a solaris 2.6 on E3000 machine for our master - also runs an ORacle
database. ONly a few clients though - 3 sun, 7 NT machines. We also have a
slave media server running on NT 4 (single CPU). We have not really done any
testing but have noticed no issue with horsepower. Both master and media
server have separate Sun L400 tape libraries (exabyte 220 in Sun clothing) -
not sure how helpful his has been - just an overview of our set up.

NBU has two classes of servers, a master server and a media server. NBU
will have a single master that holds all of the catalog information. A
media server is any machine with tape drives attached. A master can also be
a media server. The master server doesn't usually require the same hp as a
media server, but you do want enough space to allow the catalogs to grow.
My rule of thunb is make the NBU filesystem on the master equal to the
capacity of one of your backup tapes. i.e. DLT7000 about 35 gigs. You cvan
always make it less and grow it if you need to, though.
The media servers require roughly 128M of ram per datastream that is backing
up. i.e. if you have 8 tape drives, make it at least 1G of ram. CPU should
be less critical.
