Talking about virtualization and DR

It should be clear to most of us by now that server virtualization changes the disaster recovery game dramatically. Rather than having to maintain a server at your DR site for each server in your production environment, you can replicate physical, and/or virtual, servers from your production site to virtual servers at your DR site, reducing the cost of protecting production systems or increasing the number of servers you can protect.

The fly in the ointment has been that the virtual server environment at your DR site would have to handle your production loads in the event of a disaster, so you couldn’t stack too many virtual servers on a single host. SunGard’s new business continuity services for VMware addresses this problem by using different virtual server hosts during normal operations and during a disaster.

Check out this article talking about virtualization in terms of disaster recovery, an issue that I know a lot of people are talking about. Which route to take, whether to use the functionality within the hypervisor or use another layered product, what you use will depend on your business requirements.
