I have an ESXI 5.1 server based on the Gigabyte GA-Z77N-WIFI motherboard. What i want to do is to combine this and my NAS, which currently consists of 5x 2TB drives formatted as NTFS, with the view of adding more drives in the future.
My plan is to add a HighPoint Rocket 2720SGL SATA controller to the free PCI Express slot in my ESXI server, then pass that through to a Windows based Virtual Machine.
From what I gather it shouldn't really matter if ESXI has drivers or not for the HighPoint Rocket 2720SGL. All i want to do is use it in a dedicated Windows Virtual Machine. So basically passthrough to the Windows VM, install the drivers in Windows, then windows will see any drives i add to the HighPoint Rocket 2720SGL.
The end result would be my Windows VM has native access to any drives connected to the HighPoint Rocket 2720SGL and ESXI can use any drives connected to the motherboards SATA ports for datastores, as its doing now.
Basically i'm just looking to confirm I can do what I think i can before purchasing the HighPoint Rocket 2720SGL. I'm not bothered about raid as i keep my own backups on separate external drives.
