By now everyone has heard about the new Quick Storage Migration feature coming in System Center Virtual Machine Manager 2008 R2. I think it’s funny to watch Microsoft Virtualization change their tune as they slowly copy the advanced features of VMware vSphere with each new release of Hyper-V. Recall how last year, a Microsoft supporter from Kroll Factual Data declared VMotion (live migration) a “cool gimmick” that is unsafe for a production environment.
Today I’d like to point out an article from ZDNet that continues the tradition with the upcoming Quick Storage Migration feature in R2:
Unlike VMWare’s storage migration feature, Storage vMotion, Microsoft has chosen not to use a “Live” storage migration approach with their Quick Storage Migration, which suspends VM activity for several minutes while the VMs are being moved, after which the VMs are resumed from suspend. Microsoft insists that this is to ensure referential integrity of the data being moved, and that the majority of large enterprise customers which they worked with to integrate this feature did not do storage migration during production hours.
Unbelievable. Interesting use of the word “chosen.”
I’ll be sure to link back to this blog post when Hyper-V 2013 comes out and Microsoft finally has Live Storage Migration. Stay tuned!
But seriously — are you using Storage VMotion to move production virtual machines?
