The PowerEdge 2800 allowed a "daughtercard" to be added to the back plane and it be split into "2" separate back planes with separate RAID configurations. Does the 2900 support this type of configuration with SAS / SATA drives in the 1x8 backplane?

We would like to add 4 750GB SATA Drives to the existing RAID 5, 3 SAS drives in the system as a separate container
