Mix and Match Hardware
You can use any hardware configuration ifEach component has a Windows Server 2008 / R2 logo
Servers, Storage, HBAs, MPIO, etc…It passes Validate
It’s that simple!Connect your Windows Server 2008 / R2 logo’d hardwarePass every test in Validate
It is now supported!If you make a change, just run Validate again
