We're planning to upgrade our current network to Microsoft server 2008 with Windows 7 clients. Currently we have two SBS2k3 servers and 8 XP clients.
My plan so far is this:
We might buy a SonicWall TZ100 and connect our two internet modems to it, so we create a redundant connection to the internet. The SonicWall will be connected to our Cisco switch.
Our two physical servers are also connected to the Cisco switch, each in one of the two (1Gbps)ports. All Windows 7 clients are connected to the other ports (100Mbps) on the switch.
On the servers we install Microsoft Hyper-V R2.
So far the plan.
What I want is to run three virtual pc's (one with data, one with exchange, antivirus, antispam and one as application server) with Microsoft Server 2008 Enterprise R2 (we allready have the license through the Microsoft-MAPS program) on the servers. The two physical servers are needed both for load-balancing and (more important) redundancy. We require minimum downtime.
We do not have the budget to buy a SAN solution and store the virtual pc's on it. Therefor I need some other (far cheaper) solution. I found some information on the internet about software to create a mirrored volume on multiple servers. However I did not manage to find an affordable solution that supports live migration with the hardware/software mentioned above. It seems that a NAS is not supported (yet?) with live-migration.
A topic on a random forum I ran into by google-ing (I forgot the url) mentioned a software solution offered by Norton that would suit our needs. That would be great, since I can obtain internal-use licenses of Norton. However on their website I can't find a product that seems to do what I need.
Can someone please point me in the right direction? Ofcourse comments on the whole plan are welcome as well! Since our current network has some serious problems, help with this plan asap would be very appreciated.
Thank you in advance.
