Another new function is vMotion support without shared storage. This is a feature that Microsoft's Hyper-V has, and it was important for VMware to provide a similar function. This allows VMs to be migrated between hosts and nonshared storage at the same time. Thus, it's possible for a running VM to be moved from one host's local storage to another host's local storage, or from one data store to another.
On a related note, vSphere 5.1 also includes VM replication, wherein a VM can be replicated from one host to another -- say, from a primary site to a recovery site from within the host itself. This was previously available in VMware's Site Recovery Manager, but is now part of the main vSphere package.
Other additions include support for truly massive VMs with up to 64 vCPUs and 1TB of RAM per VM.
I'll be digging deeper into this new release. The initial impressions are good, but there's a lot of change in vSphere 5.1, and it may be a while before we all come to grips with the new look and feel and features -- and before the many transformations that VMware has set in motion are complete.
A summary view of a single distributed switch. Among the new features of the vswitch are a health check, configuration backup and restore, automatic rollback and recovery, and LACP support.
