Microsoft on Monday said Hyper-V's oft-delayed Live Migration feature will be part of Windows Server 2008 R2 when it's released in 2010. While that might seem like a long time for Microsoft to add a feature that VMware has had since 2004, solution providers aren't concerned that Live Migration isn't part of the software giant's virtualization portfolio.
"Live Migration is not important to us at all at this point," said Rand Morimoto, president of Convergent Computing, an Oakland, Calif.-based solution provider and Microsoft Gold partner. "With what Microsoft offers out of the box today, I'm not sure whether we have a need for Live Migration."
Live migration, an enterprise-class feature included in the VMware and Xen-based virtualization platforms, makes it possible to move running virtual machines from one system to another system. Microsoft says a feature in Hyper-V called Quick Migration, which is almost as fast as live migration, can perform virtual machine migrations in just six seconds.
Jaymes Davis, virtualization practice manager at Entisys, a Concord, Calif.-based solution provider, says Quick Migration is sufficient for both planned and unplanned scenarios.
"I may experience an outage because I need to move a virtual machine, but because I have load balancing, I won't suffer any downtime as long as I have a cluster-aware application," Davis said.
"Live Migration is a great thing to have, and in Windows Server 2008 R2, it'll definitely be something the product needs," said Davis. "But right now, Quick Migration will suffice for companies' need to stabilize on a virtualization platform that saves them money and increases their business agility."
Morimoto notes that solution providers have other methods for ensuring high availability and disaster recovery for line of business applications, including leveraging the capabilities built into the apps themselves.
