You don't need another PERC H700 to connect to extenal HDD ecnclosure but rather PCI-E SAS HBA Adapter card. You may use P/N D687J. PERC H700 is only used for internal hard drives and not external storage.
I have a PERC H700 Integrated RAID controller in my R610 server and i am not using the SAS B Cable that is currently connected the the card. SAS Cable A is in use for the RAID 10 I have set up for my OS. I bought a SAS to 4X SATA splitter cable to connect in place of SAS Cable B is so i can attach an external 5 bay HDD enclosure via eSATA. The problem i'm running into is I can't figure out a way for the server or the PERC card to recognize the connection to the HDD enclosure. It does notice the SAS Cable B is disconnected but won't acknowledge the splitter cable or anything connected to it. Is there a way to set this second connector up to be it's own dedicated port or enable it somehow similar to a SATA port on a mother board. Any help would be great. Thank you.
