All such questions are a bit dated; I'm hoping things have changed in the past year.

What do you guys use to serve a DRS cluster with vSphere 5.1/5.5?

SCSI-3 persistent reservation support would be definitely needed, VAAI is a nice-to-have.

I've seen that LIO should be able to do it; they do list VAAI as something merged into the kernel (3.14 maybe?), but that won't be available easily on Ubuntu for the time being.

What are your experiences?

The target block devices are already highly available: they are RADOS block devices exported from a ceph cluster.

Not many options. Are you sure you need VAAI? If not, QuantaStor and Zetavault are VMware HCL-supported commercial solutions based on Ubuntu. NexentaStor supports VAAI for block and NFS storage.

Reasons you may not see VAAI support for raw Linux installations:

  • Most people seeking solutions with VMware certification and VAAI primitives support typically don't roll-their-own storage.
  • Developing a proper HA clustered storage solution for VMware under Linux isn't easy. There really aren't that many production-quality offerings out there. The demand may not be there either.
