We are interested in your 6037R-E1R16N, does the raid card support all 16 hard drives or does it require another raid adapter? What cable/connectors does it use for the raid card?
For this case, yes, the cable is already included:
CBL-0421L 1 55CM IPASS TO IPASS PBF. 26AWG
In the system.
And this is the only cable you need for all 16 HDD, to connect to the RAID card in system. You don’t need extra RAID card for it.
