1 Master and 2 Media Servers each running Windows 2003 and NBU
5.1 MP4. Each server drives 2 x Quantum SDLT 220 Drives, which are
capable of 11MB/s.
=20
Strictly speaking about our backend network (non-routed, used
for backups only) each media and master server has a fiber 1000-T
connection to a non-routed switch.

I'm working here on improving the backup rates on many
of our servers and I'd like to ask everyone what has worked best for
them? We've got a gigabit back end running to most of our critical"
servers and dedicated Master and Media Servers running our SDLTs and
ATL. At this point, we think we need to focus on software settings and
network performance. I've increased the buffer the client uses for data
writes to 128KB which has shown marginal improvement, what other
settings has everyone else found success with?
