Steve,
If you're running with HP systems I can tell you right now Sun can't come
close to competing with them in regards to I/O architecture and performance.
Each of the 10 PCI slots on the back of the N Class server is it's own bus,
while there are only 4 buses in total for a 280r.
If your master server is going to just be a master server and not a media
server then it doesn't need to be that beefy. A 280r would do the trick as
a master server in your environment. I would then take the N Class server
and make it the media server and discard the R class servers. The N Class
server will blow away just about any sun server when it comes to I/O and
that is what you need for an effective media server. Just put 2 drives per
slot and you'll be set.
Are you having performance problems right now? If so, chances are it's
because of the R class servers. As near as I can tell they're only entry
class servers, probably not designed to do what you need them to do as media
servers. More details would help...
Ultimately you'd want to calculate how much data you back up in a given time
period and based on bus speed and available bandwidth calculate if your
media server(s) can handle it.

Subject: [Veritas-bu] New Veritas installation sizing
Hi,
I have been tasked with replacing the Veritas solution on site but cannot
find any information on sizing with regards to the master and media servers.
Currently I have one master server (HP N class) and two media servers (HP R
Class) controlling 19 DLT8000 drives in a StorageTek L700 tape library.
I was thinking of replacing these servers with three Sun V280R servers but
am unsure as to how to spec them up, number of processes, memory, storage
capacity etc.
We are backing up approximately 300 servers within a 10 hour backup window
which are a mixture of UNIX (mainly Solaris) and Windows machines with a
couple of Linux servers for good measure. I would be grateful if anyone out
there had any suggestions as to best spec to achieve decent performance.
Regards,
Steve.
