THANKS for all your suggestions so far...
So is there a performance difference between using the RAID card in VMDirectPath configuration vs physical RDM passthrough?
I need the lowest possible latency, but I just cannot get the disks (when RAID PCI is running on VM guest with VMDirectPath) to show in Disk Management if they are larger than 2 TB.
I even tried building a fresh VM guest running Win7 x64, newest VM version etc.
I may try the RDM thing now as a test, but will they be able to passthrough more than 2 TB to the guest?
