A major VMFS enhancement within vSphere 5.1 is the ability to support 32 hosts that can now share a read-only file/concurrent host lock.
This may not seem like a major enhancement, but it is.
Prior to vSphere 5.1, the maximum number of hosts which could share a read-only file on a VMFS filesystem was 8. This was a limiting factor for VDI deployments using VMware View, configured to deploy Virtual machines in linked clone mode as the maximum number of hosts which could share the same desktop base disk files was also 8, thus limiting us to a 8 node cluster.
In vSphere 5.1 the maximum number of hosts that can share a read-only file/concurrent host locks to 32. This will only apply to hosts running vSphere 5.1 and higher on VMFS-5. This will in turn improve the resources made available to View and vCloud Director when using fast provisioning.
Other improvements are support for 16Gbps Fibre and booting from Software FCoE
