Thank you both for your response.
I am currently in the planning phase of updating our SAN (PS6100 ver6.0.6) and our Vmware Environment (5.0). My plan is to first update the SAN to 7.0.2 then update Vmware to 5.5. But according to Dell Compatibility Guide the SAN firmware 7.0.2 is not compatible with Vmware 5.0. Has anyone update their SAN to this version and are currently running Vmware 5.0?? Just trying to see if there is going to be an issues. I am planning on spacing out the update over a couple of weeks. Any advice would be appreciated in the matter.  Thanks Conny
