Below is the part number of the cable needed to connect 8X2.5 backplane to H700 on R710. You need 2 numbers of this cable
I'm having a difficult time figuring out which cables I need for the 8bay 2.5" (MX827) backplane with PERC H700 integrated (HCR2Y) for a R710. I wish there was a place to look this all up    Thanks!
What cables for MX827 backplane PERC H700 HCR2Y?
