Virtualizing 4 Servers
Posted on 2012-03-13
So two of our four servers are depreciating and I'm considering virtualizing them (one is the Domain Controller).
In fact, I'm considering virtualizing all of our servers to one powerhouse machine that I have 2 x3440 2.53 4phys/8logical CPUs (so 8 physical, 16 Logical cores), 32GB of RAM and 12 146GB 15K SAS Drives.
Server 1: DC/Fileserver/Backup Exec/AV Manager
Server 2: 1 instance of SQL (hit by 5 users max) <- grossly under utilized
Server 3: Exchange 2010 (50 mailboxes, mid use, all under 5GB, most under 1GB),
Server 4: BES (getting rid of BES), Lync (for chat only), WSUS, System Center Essentials
Would this be worth virtualizing to a few different instances of of server:
vServer 1: DC
vServer 2: Fileserver/Backup Exec, AV Manager
vServer 3: Exchange
vServer 4: Lync
vServer 5: WSUS/SCE
Should I use a SAN or a NAS to divide up the load on the 12 15K SAS Drives?
Should I do this at all?
