How to configure an SMB file share for Azure based HPC compute nodes

For the last few weeks, I have been working with one of our major ISV applications to enable it to “cloud burst” from an on-premises HPC cluster to Azure compute nodes.  One of the key capabilities introduced with Service Pack 1 (SP1) for Windows Server 2008 R2 is the ability to provision compute nodes on…

Use of a differencing VHD can cause the Windows Azure VM Role to not start

If the parent VHD size is already at the maximum limit, then using a child differencing disk will cause the VM Role to not start.  I don’t have any official confirmation, but my assumption is that the use of the differencing disk is causing the “effective” disk size to exceed the upper limit. Recently, I…

More fun with Certificates

I ran across another problem while trying to upload another VHD to Azure. I had decided to upgrade my HPC head node to Service Pack 3 (the Release Candidate is available on http://connect.microsoft.com/hpc) and when I tried to spin up the Azure VMRole compute nodes based on the VHD that I had uploaded previously, I…

Lessons learned while uploading a VHD to Windows Azure

Recently, while attempting to upload a VHD to Windows Azure, I encountered a few perplexing road blocks.  Because it took significant research as well as trial and error to determine a work around, I’m posting my findings so that others can avoid those roadblocks. I set out to deploy a Windows Azure VM node in Windows HPC…
