Long-Distance vMotion: Part 2

This is a rapidly changing field and there have been new updates. Please see Long-Distance vMotion: Updates for the latest changes.

This is the second part in a multi-part series on the topic of Long-Distance vMotion. Part 1 introduced us to disaster recovery as practiced today and laid the foundation to build upon.

When building out Long Distance vMotion (LDVM), we still need to focus on the same components we focused upon building out disaster recovery. We will take the leap from our recovery time taking 5 minutes to a continuous non-disruptive operation. We’ll need to change our network from two different subnets in two different datacenters, to one stretched subnet. We’ll need to take our mirrored storage and create what I call a single shared storage image. Last, we’ll get rid of Site Recovery Manager (SRM) and replace it with a VMware vSphere split cluster.
