Re: Help required MSI P55-GD80 will to pay
For $100 you can pick up on Intel Pro 1000 GT and perhaps a Dell Perc 5i. You'll have something that will work without changes and you'll know that the drivers are good.
Most on board RAID controllers are software based and performance with ESXi will be very poor even if someone gets a driver working properly. If you need RAID then you'll want to go hardware RAID.
