Re: oracle on VM or non-VM ?!!

My company, House of Brick technologies specializes in virtualizing oracle. I am not a licensing expert, I specialize in Oracle, and moving from physical to virtual.
I can say that rac works just fine on VMware, but with VMware HA, the need for RAC is much reduced.

Most companies determine that VMware HA is sufficient for their needs, though we have moved several from rac on physical to rac on virtual.

The performance difference between oracle on physical and Oracle on Virtual Machines is basically nonexistent. There is a certain amount of tuning that needs to be done to optimize performance on physical machines, but once tuned the difference in performance is non-existent.

We have been around for about 20 years, so we have a lot of experience in this area.
