If you have vSphere 5.0/5.1 and have waited to upgrade to 5.5, at least in part because you have some Isilon NFS datastores, you wait is over.
In case you missed it, an updated vSphere VAAI plugin for use with Isilon storage (NFS) was released recently.
I downloaded the updated plugin from EMC’s Support Site. Looking at the release notes, OneFS 7.1.0 is the minimum version of OneFS supported.
The installation process is the same as a previous post (Configuring the EMC Isilon NAS VAAI Plugin for vSphere 5.0/5.1).
In my lab, tried it out on a OneFS 7.2.0 virtual cluster… After a host reboot, I see VAAI is supported.
I know that EMC and VMware worked together for a while to validate this package, and I’m glad to see it has been released.
