I have a Dell Poweredge 2950 in production which currently has an MD3000 attached to it using the 2 available "Left Riser Board" card slots for redundancy. I would like to add an additional Perc 6/E pcie card to the system in the available "Central Riser Board" pcie slot. However, I read something that even though the available slot is physically x8 it only works as an x4. If that is the case then I'm not sure the pcie x8 Perc 6/E will work. Is my information incorrect? Anyone using the pcie "Central Riser Board" slot? Thanks.
