Many of us have delayed installing Windows Server 2008 R2 SP1 on HP ProLiant Servers until guidance from HP became available. While writing my blogpost Preparing for upgrading your Hyper-V R2 cluster to SP1 about two months ago I was unable to find any details. Searching for an updated BladeSystem Matrix Compatibility guide, I stumbled upon the long expected HP Integration Note: Implementing Microsoft Server 2008 R2 Service Pack 1 on HP ProLiant and Integrity servers.

The long wait is over. Microsoft promised Windows Server 2008 R2 SP1 before the end of Q1 2011 and RTM is now formally announced:
Technet/MSDN availability on February 16th
Public availability on February 22nd
Service Pack 1 includes many security updates as well as a bunch of hotfixes which made installing Hyper-V a task that had to be done carefully. With everything included this will save a lot of time.
SP1 also enables enhanced support for how Failover Clustering works with storage that is not visible for all cluster nodes. In SP1, improvements have been made to the Cluster Validation and multiple Failover Cluster Manager wizards to allow workloads to use disks that are shared between a subset of cluster nodes.
There are already many blogs explaining the two most important new features for Hyper-V:
Specifically for Hyper-V it is now possible to control whether NUMA spanning is allowed. If a VM uses memory from more than one NUMA node, performance will suffer. Hyper-V will try to minimize spanning but if there is no other way it will use memory from more than 1 NUMA node. If you want to avoid this at all times just switch off NUMA spanning in the Hyper-V settings of the Hyper-V server. Of course this is more likely to occur with guests that demand a lot of memory. Now that we have dynamic memory it is also more likely that memory is used from multiple NUMA nodes.
J.C. Hornbeck has collected a number of sources on SP1 improvements:
System Center Virtual Machine Manager 2008 R2 SP1 will follow in 30 days after SP1 RTM. So expect it before the end of April 2011
I will not repeat all this but show SP1 in a few pictures:
As from today the release candidate for SCVMM 2008 R2 SP1 is available from Microsoft Connect.
This version supports managing Hyper-V hosts with the new SP1 functionality: Dynamic Memory and RemoteFX.
Hopefully you can still find the SCVMM 2008 R2 SP1 RC section, because moments after I started downloading the package I could not find the dashboard entry for the product in Microsoft Connect

Just got news that SP1 Release Candidate is ready for download:
Today, Microsoft has made available a Release Candidate (RC) for Service Pack 1 for Windows Server 2008 R2 and Windows 7. SP1 includes both a roll-up of operating system updates and several new capabilities for Windows Server.
Microsoft RemoteFX introduces a new set of remote user experience capabilities that enable a media-rich user environment for virtual and session-based desktops. RemoteFX can be deployed to a range of thick and thin client devices, enabling cost-effective, local-like access to graphics-intensive applications. RemoteFX also supports a broad array of USB peripherals to improve the productivity of users of virtual desktops.
SP1 also includes Dynamic Memory, which enables servers running Hyper-V for server virtualization, to be more efficient in the use of memory. Dynamic Memory pools and distributes memory among the virtual machines running on a physical host, enabling higher consolidation ratios, increasing server utilization rates, and providing more flexible workload management. Furthermore, memory is dynamically added based on the demands of the current workloads and without service interruption.
Expect to see Service Pack 1 released in its final form during first quarter 2011 and whether you’re virtualizing servers or desktops, take a few minutes to learn more about Service Pack 1 here. You needn’t wait for SP1, however – you can join those already enjoying the benefits of Windows Server 2008 R2 by deploying today.
The official beta of Windows Server 2008 R2 (and W7) SP1 is now available:
So if you want to test Dynamic Memory and RemoteFX for superb graphical user experience in a virtual machine, here is your chance.
As Ben Armstrong pointed out in his blog that the full choice of supported operating systems will be available with the official version of SP1:
Supported with beta:
Additional support with final version of SP1:
