Some questions on VMware support -

1) The QuantaStor Key features page at shows support for ESX/ESXi. Which version(s) is (are) supported?
2) Does Quantastor support VAAI? Which ones?
3) Are there any vCenter plugins from QuantaStor?
4) The VMware compatibility Guide at does not yet show QuantaStor or OSNexus. Is there a plan to obtain an official compatibility stamp from VMware

Hi Gopi,
All versions of VMware ESX/ESXi 4+ are supported but we don't yet have support for VAAI or vCenter plugins. Those are on the roadmap. We are also planning to get an official compatibility stamp from VMware. We use the same open-source SCST driver stack that is used by some storage companies that have taken their hardware through the VMware cert process so it should go fairly quickly.

Any advance on official compatibility with VMWare. That stamp is important to our clients.

Hi Paddy,
We're making good progress on it, we'll have an update on the forum here within the next couple weeks with more detailed progress.

When you go through the testing process could you get certified for NFS shares also?

While not certified yet, I've used QuantaStor /w ZFS & NFS very successfully has a virtual SAN using passed through LSI controllers and a large JBOD unit with my ESXi 5.x servers.

Almost a month has gone by since the "couple of weeks" post by Steve, just wondering where you are in the process?

Hello Chris W,

I believe we have an open e-mail thread regarding this topic with your Team.

We will send you a reply via that thread.

Thank You,

OSNEXUS Support.

Chris, Paul,
Quick update here; OSNEXUS is now a VMware Elite partner and are working through iSCSI certification with VMware 5.1 first. This will be followed with VMware 5.5 cert testing and additional protocol coverage (NFS/FC).

Any update on VAAI?

Hello Alton,

The full VAAI feature set support is on our roadmap and we plan to have it available for release in a few months.

Thank You,
Chris Golden

I heard that some of the VAAI primitives are now supported. If this is correct, which ones and which version of QS has this support?

All but the server side copy operation. We're working on adding some hooks into the SCST driver so that we can integrate that command with Storage Volume snapshot/clone and other operations within QuantaStor.
