Hi, Let me understand your enquiry, you're going to replace PERC6i with H700 and connect the backplane to H700 via cable N170M and M246M? Whilst, backplane W814D is not originally installed in your server before? If all above is yes, then you're on the right path with both SAS cables. But don't forget backplane power cable, XT622. SFF-8087 cables are generally SAS cables, but the connectors must be a 'right angle' connectors, else it will not fit into the chassis. [IMAGE]  
I'm looking to replace the PERC 6/i that in my PowerEdge R710, with a 3.5" SAS backplane (W814D). I've looked around and found that N170M and M246M should both be compatible. But looking at it it looks like it could work with any SFF-8087 cable. Is this the case?
What cables are compatible with PERC H700 and PowerEdge R710?
