I'm prepping for migrating our existing SBS 2003 domain onto new hardware & OS (SBS 2008 or SBS 7 if it releases in a reasonable timeframe). I'd like to run the new SBS server on Hyper-V to make future hardware upgrades easier, reduce disaster recovery times, and to reduce my box count (linux/web servers, etc).
We currently have:
Dell PE 2900 II dual core Xeon 2.0GHZ (can't recall model...conroe or wolfdale).
2x160 7200rpm SATA in RAID 1 (OS & Exchange)
3.500 7200rpm SATA in RAID 5
PERC 5i controller
Usage: Exchange, WSUS, Symantec Endpoint Server, heavy file sharing. 35 computers, 30 users. Things seem to bog down during peak work hours. We run 1GB ethernet, and I've been told the issue is our RAID performance and low RAM.
I'm looking for recommendations on what/how to spec the new server. In particular, what should I do about hard drives & RAID arrays? Since the server will be virtualized, is there any point to a RAID 1 + RAID 5 setup? Should I run one larger RAID 5? A RAID 10 with partitions?
One option I thought of would be to virtualize both servers (SBS Premium offers 1 SBS license + 1 standard) on different volumes (ie I can put the VM file for the SBS server on the host machines RAID 1 volume and the standard server on a RAID 5 or 10) but I don't know if that would really make any sense!
As you can probably guess, I'm a bit confused, and this is only 1 of the hats I wear. This is what I'm thinking of for a new server:
Dell R510 or 710 Quad core (single processor)
6-12 10k or 15k SAS hard drives. (more drives if I go with the cheaper 146GB drives, or less if I use 300 or 600GB drives)
Don't know what to do about RAID!
I will check back religiously and provided any additional requested information asap.
