I pulled the drives on the server to see what was in there, under the settings - component consol page it says the maximum storage is 7957GB. When visually inspecting the drives, the server has two WD 2TB KDISK-2000-L drives, one 4TB HGST drive, and one WD Purple 6TB Surveillance drive. The two 2TB and one 4TB drives are Kaleidescape certified drives, the WD Purple is not. Could someone explain what I am looking at here please? Perhaps a RAID explanation on this setup too please?
