What’s new in vSphere 5.1 part 6 September 25, 2012Posted by vbry21 in Uncategorized.

As a Hyper-V trainer and a VMware trainer I look at both products, and one of the nice features of Hyper-V in Windows Server 2012 is the live migration without shared storage, and this led to many questions about “Why don’t VMware have that?” As I’d signed my NDA with VMware I simply said, that at the moment we can’t do this, but now with VMware vSphere 5.1, I can say we do.
Enhanced vMotion enables a VM to change its datastore and host simultaneously, even if the two hosts don’t have any shared storage in common.
Another way of looking at this functionality is supporting VMotion without shared storage. To use this enhanced functionality the hosts must be connected to the same VMware vCenter and be part of the same datacentre object. Also the hosts must be on the same layer-2 network.
This vMotion enhancement ensures, zero downtime migration, no dependency on shared storage, and lower operating cost as a SAN is no longer required (but I’d still have one, I really like High Availability).
