I believe you are having a cabled hard drive system. If you need to use PERC controller on this system you need to use a PERC controller and use correct cable for the controller. Both PERC 6 and PERC 7 is supported on T310. Based on PERC controller you are going to order you need to use appropriate cable Cable for PERC 6 Cable for PERC 7
