One of the features not being talked about too much in Windows Server 2008 R2 Hyper-V is the ability to add new storage.  What does this mean?  It means you can add new virtual hard disks (VHD’s) to a VM while it is running.   It does not mean you can resize a VHD while the VM [...]

W2008 R2 Hyper-V Memory More Efficient

November 27, 2009 // 1 Comment

I’m seeing the real world results of this.  We’re getting a little bit more out of the gigabytes of RAM that is in each of our hosts with Windows Server 2008 R2 Hyper-V instead of its predecessor, even with our hardware which does not have the very latest processor. One of the main players [...]

Unlike VMware’s VMFS, we can extend a Cluster Shared Volume (CSV) without doing trickery that compromises performance.  And has has been documented by Hans Vredevoort (clustering MVP) it is very scalable. How do you resize or expand a CSV?  It’s a pretty simple process: Use your [...]

Virtualisation: The Undersold Truth

November 27, 2009 // 0 Comments

Ease of administration. To a sys admin, those 3 words mean a lot.  To a decision maker like a CIO or a CFO (often one and the same) they mean nothing. It’s rare enough that I find myself working with physical boxes these days.  Most everyone is looking for a virtualised service which is [...]

W2008 R2 Hyper-V Network Speed Comparisons

November 26, 2009 // 1 Comment

Hans Vredevoort asked what sort of network speed comparisons I was getting with Windows Server 2008 R2 Hyper-V.  With W2008 R2 Hyper-V you get new features like Jumbo Frames and VMQ (Virtual Machine Queue) but these are reliant on hardware support.  Hans is running HP G6 ProLiant servers so he [...]
