Windows 8 Server official name announced
During the first of two keynote addresses by Brad Anderson at MMS 2012, Windows Server 8 will be henceforth known as Windows Server 2012. Jeff Woolsey gave a brief but informative demo of some of the virtualization and cloud related features of the OS.
Can't wait to get home and try the latest beta!
One of the most compelling features of Windows Server 2012, as it relates to virtualization, is the idea that there is no resource usage tax, as is the case in certain other hypervisors.
For example, you can assign up to 1 terabyte (yes, terabyte) of RAM to a virtual machine, with no extra coast.
What about disk size? Up to 64 TB per volume. Again, at no extra cost.
Virtual processors? I saw one demonstrated that had 32 virtual processors. Guess how much extra Microsoft charges you for those extra vprocs? Nothing, nada, zilch.
One place HyperV has been lagging is in its migration capabilities. With WS2012, you can now perform live migrations of not just the VM, but the storage as well. Not good enough? They've got one more trick up their sleeve: "Shared Nothing" migrations.
"Shared Nothing" migrations will allow you to migrate a virtual machine between clusters, or even datacenters, where there is no shared infrastructure. All you need is network connectivity. No more having to to perform a V2V (or do the remove from/add to inventory trick) to move a machine to a different cluster.
Network virtualization is another big point. This will be a huge feature for multi-tenant hosts. In a nutshell, this allows you to have isolated network segments within your HyperV environment, in which you can even duplicate IP addressing, with no issues. Think isolated VLANs; it's the closest analogy that I can think of. But with the added bonus of being able to move or extend them at will to another cluster or private cloud. Very cool stuff!
