The second session for today is the Hyper-V 2006 R2 SP1 Dynamic Memory Allocation session by Ben Armstrong. This is actually really cool technology that will allow Hyper-V to allocate RAM dynamically to virtual machines as it’s needed. What this means to us is that we can configure a VM to use say 2GB of RAM, but it will only use that 2GB of RAM when it really needs it. Similar to the CPU allocation that we have now, this feature really gives us the chance to add more virtualisation instances to a given host than ever before. Very cool technology indeed. Most of the time, this technology is only available in the Enterprise versions of Windows Server, the good news is that this will be available on ALL versions of Windows Server 2008 R2 and HyperV Server 2008 R2 once Service Pack 1 is released and applied to those systems.
