Hyper-V RTM

From Microsoft TechNet:

The next generation hypervisor-based server virtualization technology for Windows Server 2008 is here. Windows Server 2008 Hyper-V is now released to manufacturing (RTM) and is available for deployment into production environments. You can download the Hyper-V role update here.

With Hyper-V you can consolidate workloads of underutilized server machines onto a smaller number of fully utilized machines. Fewer physical machines can lead to reduced costs through lower hardware, energy, and management overhead. The thin microkernel hypervisor architecture with integrated management tools allows you to manage both physical and virtual resources. Hyper-V easily plugs into your IT infrastructure to leverage your existing patching, provisioning, management, support tools, and processes.

At Billhighway, we’re been evaluating Virtualization software for some time now, including previous versions of Microsoft’s Virtual Server 2005 (& R2), and Virtual PC, as well as VMWare, Parallels & BootCamp.  Each has strengths and weaknesses, but overall if you haven’t yet begun evaluating virtualization software there’s never been a better time.

Over the past year, we’ve successfully consolidated about 25 servers onto 3 physical servers, most recently with Hyper-V.  Our latest deployment features a Dell PowerEdge R905 and boasts 4 quad core procs (16 cpu total) with 8 – 2.5″ 10K SAS hard drives and 16GB of memory.  Its a beefy server that is currently running about 15 virtual servers with utilization at a mere 15%.  That said, our implementations of virtualization targets application servers, whereas we do alot of backend processing in a GRID-computing fashion, so workloads are fairly optimized, which make them ideal candidates for virtualization.

If you’ve deployed RC0/1 the upgrade path is pretty straightforward, if you were working with beta’s prior, you’ll need to install the update and re-deploy your virtual machines.  Integration components will also have to be updated.
