Minimizing the burdens of moving to Windows Server 2008 R2

Hi Arieh,
My suggestion would be to first consider using Windows Server 2008 R2 with the new Cluster Shared Volume (CSV) feature. This would greatly increase your ability to host multiple VMs on the nodes on your cluster. In addition, it will allow you to use the new Live Migration feature of Hyper-V R2, and will lower your total downtime used for migration and maintenance.

Maximizing the number of VMs on a server?

Very nice post, Kevin. If I may, I would just like to remind Joseph that he can use Pass Through Disks for high I/O applications hosted on VMs, such as SQL and Exchange Mailbox servers. That will allow the VM to work against the disk in a manner that is very much the same speed and performance of a non VM machine.

32-bit software on 64-bit system?

Hi Michael,
As Andrew said, the Windows 7 XM-mode (XMP) under Virtual PC can help you run most legacy applications. However, it does require that you use a virtualization-capable CPU (Intel-VT or AMD-V), plus have enough memory to run the virtual machine. So as long as your host machine is powerful enough, you're ok.

Adopting Windows Server 2008 R2 – without copying GBs of zeroes?

Daniel,
I already gave a similar answer here on the site. I suggest that you take a look at www.VMUtil.com.
They have 2 cool (and free) tools that can help you alleviate SCVMM pain.One of them is VHDCopy.exe.
If you have a 60GB VHD file with 40GB free, VHD copy will avoid reading the 40GB and send it across the network. By default, it will also not write the 40GB. With the /Secure option, it will write 40GBs of zeros, but the read and the xmission of the 40Gbs is still avoided.

Scaling web and database services – without going dark?

I would strongly suggest looking at a reverse proxy solution that will effectively increase your ability to serve static (and in some cases, non-static) content from the webservers. I've seen solutions like ISA 2006 do wonders to performance.
