Between MMS and TechEd there have been a lot of announcements on the virtualization and cloud computing front. First, over on the Virtualization Team Blog, Jeff provided the announcement and details around some new capabilities coming in Hyper-V with Windows Server 2008 R2:
64 logical processor support. A 4x improvement over Hyper-V R1 and means that Hyper-V can take advantage of larger scale-up systems with greater amount of compute resources.
Support for up to 384 Concurrently Running Virtual Machines & 512 Virtual Processors PER SERVER. We are increasing the maximum number of concurrently running virtual machines to 384 per server and the maximum number of virtual processors to 512 for the highest virtual machine density on the market.
Processor Compatibility. Processor compatibility allows you to move a virtual machine up and down multiple processor generations from the same vendor. This does not mean you can live migrate between Intel and AMD nodes, just between different generations from the same vendor.
Not to be outdone, the VMM team announced a bunch of new features that will be in their Release Candidate coming out in a few weeks:
Combined, these new features from both teams enable some key scenarios at both the entry level and high end of the spectrum. One of the major advantages of our stack is that it is very approachable from an entry level since it leverages so much of what your administrators already know and beginning with Microsoft Hyper-V Server 2008 R2 SKU, will be available with all of the high end features (Clustering, Live Migration, etc) for free. Within a couple hours a Windows admin can become proficient with the basics of Hyper-V and be up and running (for free!). Within a few days at most, the ability to implement basic clustering, HA, and Quick/Live migration can be achieved. At the high end, very advanced architectures can be implemented including VMM, OpsMgr, deep SAN integration, etc. This is where our technical guidance, solution accelerators, and service offerings come into play.
To see an example both of how this stack is being leveraged by commercial providers as well as an example use case for enterprises wishing to use the cloud as reserve capacity, check out the video below demoing a future version of VMM and how it will integrate private and public cloud capacity seamlessly:
