I had this question after viewing
Upgrade RAID Controller card on Dell PowerEdge 2900.
I got a 2900 from a school I work at. I'm still a student myself. I heard the h700 would work and I blindly bought one so I could use my 3TB drives in the 2900. but there are two connectors that connect to original raid card that seem to come from the HDD bay, but the new raid card doesn't have those connectors, I'm lost as to how this is gonna work. any hints?
