VAAI-NAS, vCloud Director and Cloning Offload Strangeness

tintriI 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?

vCloud Director 5.1 & Storage Profiles

In my 10 part series of posts on the new vSphere 5.1 Storage Features, I called out in part 3 that there was now even greater interoperability between features like Profile Driven Storage and vCloud Director. The purpose of this blog is to highlight this particular interoperability in even more detail.

The requested operation will exceed the VDC’s storage quota

vSphere 5.1 introduced a number of vCloud Director (vCD) interoperability features from a storage perspective, namely ability to take VM snapshots from within the vCD UI, interoperability with Storage Profiles and interoperability with Storage DRS. Admittedly, its been a while since I played with vCD and I am a little rusty, but I wanted to see how well these storage features worked with vCD 5.1. I’ll follow-up with some future posts on how this all integrates, but this first post is just to highlight an issue I ran into in my haste to get the environment up and running.
