HP has published a technical whitepaper focusing on the performance characterization of the disk sub-system for HP StorageWorks P4500 21.6TB SAS Multi-site SAN Solution (HP P4500 SAN), addressing questions a customer may have about deploying Microsoft’s Hyper-V R2 virtual machines (VMs) on HP ProLiant BL490c G6 Virtualization Blades (ProLiant BL490c G6) with HP P4500 iSCSI [...]

HP MPIO Full Featured DSM for HP EVA now supports Cluster Shared Volumes
In an HP Storage Works EVA Best Practices document published in February 2010, we were advised not to use the HP MPIO DSM with Cluster Shared Volumes, but as an alternative to use Microsoft Native MPIO only. This was unfortunate because the HP MPIO Full Featured DSM allows for better visibility and control of the [...]
Conditions when DPM cannot backup a Hyper-V VM
We recently saw a situation where a running VM could not be backed up by Data Protection Manager.
Here is why:
If at least one of the following conditions is true
The Hyper-V integration components for volume snapshot copy disabled for the VM
Dynamic disks configured inside of the VM
Non-NTFS based partitions inside the VM
Changed shadow storage assignments [...]
My Cluster MVP award has been renewed for 2010
This afternoon I got the great news. I received confirmation of my second Microsoft MVP Cluster Award. It is always very stimulating knowing that people @ Microsoft and in the community out there appreciate my Hyper-V / Cluster technical contributions on my blog and on Twitter. It has been really worth it. Being an MVP [...]
Update hotfix list Hyper-V R2
I came across a new Hyper-V R2 hotfix on the list related to Intel Westmere processors (Nehalem EP/W5580).
“This issue occurs because Intel Westmere processors have a new Virtual Machine Control Block (VMCB) caching feature. This feature is added to provide a virtualization assistance to increase the hypervisor performance. Because this feature was introduced after Windows [...]
Hyper-V updates & hotfix list
Some time ago I asked MS to split the list for Hyper-V updates in R1 and R2. Well … they did and thanks a lot!

Azure is running future version of Hyper-V
VMware is targeting MS for not using Hyper-V for their virtualization platform. Well in fact they are not using Hyper-V current version but Hyper-V vnext (possibly even vnext R2) version. Hyper-V R2 already benefited from the experiences with Azure Hypervisor and the upcoming Hyper-V or even the next service pack will benefit in an identical [...]
Azure V2V seems inevitable
In my November blog I talked about moving virtual machines to the cloud. More evidence of an upcoming Infrastructure as a Service (IaaS) can be found on MSDN, which describes virtual machine sizing, ranging from 1-core (Small) to 8-core (ExtraLarge) virtual machines with memory up to 15GB of memory and 2TB of disk space.

Hyper-V Best Practices Analyzer is not yet available for Windows Server 2008 R2
[Update January 28, 2010: Mike Sterling from Microsoft informed me that the article was erroneously published. There is still some work to be done internally before it can be made available]
Microsoft has a reputation of writing good best practices analyzers. Some of the newer ones are integrated in the Server Manager of Windows Server 2008 [...]
HP offers virtualization smart bundles with Hyper-V
After VMware joined forces with Cisco en EMC (VCE) in vBlock, it is not difficult to see that HP is hugging Microsoft giving Hyper-V and System Center a lot of extra attention. On the other side of the fence we see Microsoft, Citrix and HP (MCH) forming an opposing, let’s call it vPower, alternative. It [...]
Moving a Hyper-V virtual machine to Azure
Although not fully embracing the capability and scalability of the cloud, Ray Ozzie, chief software architect from Microsoft, talked about the ability to move a virtual machine to the cloud. I heard about it on Twitter and went on to look for the source. Apparently it was talked about during the PDC which is held [...]
Fix for accidentally deleting a VHD with Virtual Machine Manager 2008 R2
Thanks to a tweet from @MSManageability, I finally know how to prevent losing a VHD with VMM2008 R2. If you choose to delete a VHD from an existing VM it actually deletes it.
J. C Hornbeck pointed me to a hotfix (KB976246) which addresses this problem.
See his blog: http://blogs.technet.com/scvmm/archive/2009/11/16/kb976246-removing-a-vhd-from-a-virtual-machine-in-vmm-2008-r2-deletes-the-file-on-the-hyper-v-server-without-warning.aspx
