Im gonna answer the questions the best i can (lousy memory )
Well its a pretty simple setup really... i have 15 servers of different types, SQL, exchange, file servers. All of them attached to the network currently via 100Mbit network adapters, All of the servers will be replaced this winter, for newer models with Gbe. The servers themselves are attached to a Procurve 4108GL switch, with a backplane of about 36GBit.
Well basically its like this:
2 file server, around 600.000 documents, and different other types of files= 170GB
6 SQL servers, the biggest at 40GB database, all in all 65 GB database.
6 citrix servers, wich i just need to be able to Disaster recover= 30GB
1 exchange, with a priv.edb of around 10Gigs, and a pub.edb of around 1gig.
and 2 servers doing different oddjobs= 10 gigs
We have IDR, accelerator, agents on all our servers and ofcause SQL and exchange on the respective servers
Alltho we generally atm. make backup of a flat dump file, and the logs, because of speed issues with making backup from the databases themselves. Our primary database server dumps to a internal DAS 3 times a day, but i only need to make one backup of it once a day.
That was sort of also my idea sooner or later, im going to test the speed my backupserver gives me(it runs some printing jobs too but thats it) at first, and then im gonna make a trial copy on the storage server, to see what that gives me. I can see the benefit of removing the backup task from our "production" servers.
But time will tell.
