A short note to clarify something that has come up a number of times in recent weeks here at VMware. There have been a number of discussions about whether or not we support NFS over IPv6 on vSphere 5.x, and again, on whether or not we support the VAAI-NAS primitives in the same context.
VAAI is an API for offloading tasks to the storage array, but for offloading tasks to NAS arrays, storage vendors need to create their own plugins for the ESXi hosts to achieve this. You can learn more about VAAI-NAS by clicking here. So what about IPv6 support and NFS? And VAAI-NAS?
I was in a conversation with one of my pals over at Tintri last week (Fintan), and he observed some strange behaviour when provisioning VMs from a catalog in vCloud Director (vCD). When he disabled Fast Provisioning, he expected that provisioning further VMs from the catalog would still be offloaded via the VAAI-NAS plugin. All the ESXi hosts have the VAAI-NAS plugin from Tintri installed. However, it seems that the provisioning/cloning operation was not being offloaded to the array, and the ESXi hosts resources were being used for the operation instead. Deployments of VMs from the catalogs were taking minutes rather than seconds. What was going on?
During VMworld 2012 in San Francisco, I had a chance to catch up once again with the team from Tintri. My first introduction to Tintri was at last year’s VMworld, where they received runner-up in the ‘Hardware for Virtualization’ category by TechTarget for best of VMworld 2011. Well this year they went one better, and won the Best of VMworld 2012 Gold award in Hardware for Virtualization. And for good reason. Let’s see the enhancements to the Tintri platform over the last 12 months have brought.
VAAI NAS introduced the ability to create LazyZeroedThick & EagerZeroedThick disks on NFS datastores. Without VAAI NAS, one can only create thin VMDKs on NFS datastores. For those of you who are using VAAI NAS plugins, there is an important note in the 5.0U1 release notes that you should be aware of.
ESXi cannot distinguish between thick provision lazy zeroed and thick provision eager zeroed virtual disks on NFS datastores with Hardware Acceleration support
I’d met Virsto Software at previous VMworld conferences, but never had a chance to have a meaningful discussion regarding their products and solutions. On a recent trip to the US, I had the pleasure of meeting with Eric Burgener at the Virsto offices in Sunnyvale. He kindly took the time to give me an overview of their Virsto for vSphere 1.5 product.
I recently had the pleasure of chatting with Jesse St. Laurent, Product Director at a new storage startup called SimpliVity. SimpliVity finally exited stealth mode today, but has been around since the end of 2009, with development starting in earnest in 2010.
The name of the hardware storage appliance which SimpliVity have just announced is the OmniCube. Having asked Jesse to describe the features of the appliance, he listed the following:
EMC Isilon are providing even further vSphere integration features in their upcoming ‘Mavericks’ release of their OneFS operating system. This is great to see. The integration is in the area of vSphere APIs, both for Array Integration (VAAI) & Storage Awareness (VASA).
