8247-21L, 8247-22L, 8247-42L, 8284-21A, 8284-22A, 8286-41A, or
8286-42A
This configuration uses the base function disk drive backplane.
The base function storage configuration includes:
v One PCIe3 x8 SAS RAID internal adapter 6 Gb, with RAID 0,10,5,6
v One base function disk drive backplane that supports 12x SFF (2.5") bays
v One Slimline DVD bay
v Two mini SAS HD cables
Example: Base function disk drive backplane for 5148-21L, 8247-21L, 8247-22L,
8284-21A, or 8284-22A
