Hc2995,  The part number for the H330 controller is 4Y5H1. you wouldn't likely need the cable (part P9VFY) withyou not exceeding 6 hdds. Let me know if this helps, or if you have any other questions or concerns. 
Hello,  I currently have a T330 with the PERC s130 and need to add 2 more hard drives for a total of 6. As far as I can tell the S130 is not capable for adding more than 4 drives so I wanted to know what the part number for the PERC H330 would be? Do I need any thing else besides the H330 card? The server is already equipped with back plane and hots swap SATA drives.  Thank you!  Regards, Howard
T330 replace PERC S130 with H330
