New virtualisation / Win 2008 R2 setup
Have been lurking here for a bit but took the plunge and decided to register as I'm looking for some advice. Before I start I should mention I don't actually work in the Education sector ( I used to), I work for a charity now. I'm also not sure what forum this should be in, so a mod might want to move it.
I currently have the following setup:
Approx 60 users with approx 40 PCs (all running Win XP)
1 Win 2003 DC (Dell 2900 2Ghz 4Gb RAM) This pretty much runs everything, DNS, File and Print (using DFS), Exchange 2003 (80 users over both sites).
Approx 20 users with approx 10 PCs (running Win XP)
This has only recently opened and is currently connected to Site A via VPN over an ADSL connection.
It has a temporary PC running Win 2003 R2 acting as a local DC, along with File server (using DFS) and print server.
I'm planning to have a 20Mb connection between sites, for use with VOIP, video conferencing, general network connection.
I'm looking to be able to run Site B as a Disaster Recovery site, so if anything was to happen to the server at site A it doesn't have as big an impact on everyone as it would currently. I'd also like to upgrade to Win 2008 R2 and Exchange 2010 ( and further down the line Windows 7)
My plans are something like the following:
- Purchase a new server for Site A and install Win 2008 R2, setup multiple Virtual Machines on it e.g.
VM1 - DC (also keep a physical server as a DC, possible a HP ML115 which I have)
VM2 - Exchange 2010 (not sure if standard or enterprise, but may make use of the Unified Comms stuff)
VM3 - File server (DFS), print server, WSUS, Antivirus
VM4 - inhouse database accessed via IIS, which will probably move from Access to SQLserver
- Purchase a new server for Site B with Win 2008 R2
VM1 - DC
VM2 - File server (DFS), eventually setting up branch cache
Other VMs - ???
What would be the best way of being able to switch over to running Exchange from Site B incase something happened server at Site A. Could I setup DPM 2007 or 2010 in Site A to backup the VMs and then also setup DPM in Site B, with Site B backing up the VMs from the DPM in Site A
This way in an emergency I would just need to setup a VM on site B with the image of the Exchange VM from Site A ? Would this work ?
I had thought about the possibility of getting 2 servers for site A with shared storage to store the VMs, to add extra redundancy, but budgets might prohibit this. The Sun 7000 series SANs get recommended here but might well be too expensive. Also not sure how to replicate the data to Site B.
Had also thought about possible using a HP Lefthand multi-site Virtual SAN. Again costs might prohibit this.
I have been thinking of going with Hyper-V for the VMs due to the fact that as a charity we can get cheap Microsoft products.
I have approx £13k ish of a budget for this, any thoughts on my plans, recommendations on hardware etc.
