We use windows, not linux(unix), so take that into account.
All of our servers have 8 GB of memory. I think that is at the low end
of what Legato wants, but every time I run performance monitor, it
always tells me that I have at least 5GB free, even during the heaviest
backup periods. I've always wanted to add more memory, just to see
what it would do, but have never had the money...
We have 3 networker servers, plus some storage nodes, and backup about
500 clients..
Our biggest bottleneck is the NIC. We do some dedicated storage nodes,
for direct backup to tape, but sometimes that machines can't push the
drives to their fullest. We are working towards 10Gig, but haven't made
it that far - yet.

Subject: [Networker] How much memory on a server
We are in the process of upgrading our backup hardware. We have an
existing IBM 3650 that we will repurpose as our backup server. It
currently has 2 GB of RAM which we think is not enough. How much memory
is appropriate?
Background: We are currently running NetWorker V7.5.1 and backup around
3 TB per week. Weekend full backups are in the neighborhood of 2-2.5
TB. The new library will have 3 LTO-4 drives (probably upgraded to
LTO-5 eventually) connected with fibre channel and the new server will
have a 10 GB network connection. When we were looking at the big dedup
project last spring the consultant suggested we have 24 GB of memory in
the server but that seems like overkill as we won't be doing backup to
disk or dedup at this time.
Any advice will be appreciated.
Thanks, Dave
