I've got a similar setup running here - with the Nexenta VM set to auto-start, you have to wait a bit for the VM to startup until the NFS datastores become available, but the actual mount operation from the ESXi side is automatic. I suppose that if you played with the startup delays between virtual machines you could get everything to start unattended once you know how long it takes for the NFS stores to become available. Combined with send/recv to another box it's an affordable disaster recovery solution. And to squeeze every bit of performance out of the configuration, you can use VMDirectPath to present the HBA to your storage VM (just remember to add another card to boot ESXi or store a VMFS volume for vmx and swap files.
