We are trying to configure an RS2BL080.
Motherboard - S5520HC
Chassis - SC5600LX
Four drive expander backplane
Six drive expander backplane
RAID level - 50
My question is what is the best practice to connect the cables from the RAID controller to the expander backplanes? Do I connect one cable to JT6 Ports 0-3 on the controller then the four SAS connectors two to each expander backplane or should I use one separate cable for each individual expander backplane? Example: JT6 Port 0-3 on the controller then two SAS connectors to the six drive expander backplane and a second cable to JT7 ports 4-7 on the controller and two SAS connectors the the four drive expander backplane. I hope this makes sense. Any help would be appreciated.
It makes no difference. You have eight ports available on the RS2BL080. Four ports from each SFF-8087 connector. The expander backplanes each have two ports. Whether you connect each two expander ports to one SFF-8087 or two, you'll still be using four ports for both expander backplanes. One thing to consider, using a single cable would clean up the installation by not having four unused cables to contend with.
