Windows Server 2008 R2 SP1
On behalf of the Windows Server and Cloud teams at Microsoft, I’m pleased that today we released Service Pack 1 for Windows Server 2008 R2 and Windows 7 – adding two new virtualization capabilities: RemoteFX and Dynamic Memory. To learn more about RemoteFX, take a look at Michael’s Kleef’s blog posted today. I’ll cover Dynamic Memory and a few other updates you’ll want to understand.
Dynamic Memory and Virtual Desktop Infrastructure
· What is Dynamic Memory? What problems does it solve?
· Is Dynamic Memory good for Servers and VDI?
· How does it compare to VMware’s Overcommit?
· How does Dynamic Memory work?
A: Here are the links to a six part series titled Dynamic Memory Coming To Hyper-V and an article detailing 40% greater virtual machine density with DM.
Part 1: Dynamic Memory announcement. This blog announces the new Hyper-V Dynamic Memory in Hyper-V R2 SP1. It also discussed the explicit requirements that we received from our customers. https://blogs.technet.com/virtualization/archive/2010/03/18/dynamic-memory-coming-to-hyper-v.aspx
Part 2: Capacity Planning from a Memory Standpoint. This blog discusses the difficulties behind the deceptively simple question, “how much memory does this workload require?” Examines what issues our customers face with regard to memory capacity planning and why. https://blogs.technet.com/virtualization/archive/2010/03/25/dynamic-memory-coming-to-hyper-v-part-2.aspx
Part 3: Page Sharing. A deep dive into the importance of the TLB, large memory pages, how page sharing works, SuperFetch and more. If you’re looking for the reasons why we haven’t invested in Page Sharing this is the blog. https://blogs.technet.com/virtualization/archive/2010/04/07/dynamic-memory-coming-to-hyper-v-part-3.aspx
Part 4: Page Sharing Follow-Up. Questions answered about Page Sharing and ASLR and other factors to its efficacy. https://blogs.technet.com/b/virtualization/archive/2010/04/21/dynamic-memory-coming-to-hyper-v-part-4.aspx
Part 5: Second Level Paging. What it is, why you really want to avoid this in a virtualized environment and the performance impact it can have. https://blogs.technet.com/b/virtualization/archive/2010/05/20/dynamic-memory-coming-to-hyper-v-part-5.aspx
Part 6: Hyper-V Dynamic Memory. What it is, what each of the per virtual machine settings do in depth and how this all ties together with our customer requirements. https://blogs.technet.com/b/virtualization/archive/2010/07/12/dynamic-memory-coming-to-hyper-v-part-6.aspx
Hyper-V Dynamic Memory Density. An in depth test of Hyper-V Dynamic Memory easily achieving 40% greater density. https://blogs.technet.com/b/virtualization/archive/2010/11/08/hyper-v-dynamic-memory-test-for-vdi-density.aspx
RemoteFX
RemoteFX is an exciting technology that lets you virtualize the Graphical Processing Unit (GPU) on the server side and deliver next-generation rich media and 3D user experiences for VDI. RemoteFX is also enabling new low cost ultra-thin client devices to enter the market. Together, these technologies will drive down the end-point cost and reduce endpoint power consumption to as little as a few watts.
Customers have already been successful with Dynamic Memory and RemoteFX, in early adopter deployments.
