Hi guys,
I finally got a chance to try and play with Vmware Virtual Volumes (VVOL) today (available in vsphere/vcenter 6.0) and discovered that the UCS doesn't seem to support it.
I have a Nimble storage array (think SmartStack) that is running the software required for VVOL support (2.3.4).
We enabled everything on the array but then ran into an issue where the hosts couldn't connect to the VVOL volume.
It turns out that there needs to be an additional capability present on the HBA. It is called second level lun ID (SLLID).
None of the VIC adapters seem to support this feature with the drivers I have. I checked the release notes and found nothing.
Is there a target date when this feature will be added to the VIC drivers? I assume that it will be added considering the large number of customers running vmware on UCS (Flexpod, Vblock, Smartstack).
Vmware KB on the issue.

Output from my UCS that shows there are no capabilities listed.
