PCI-E Cables
PCI-E cabling is required to connect the SSG-136R-NR32JBF to the server node's host
interface card(s). The chassis has four external PCI-E x16 ports, which can be split to eight
x8 ports to support up to eight hosts.
Connect the PCI-E cable from the server node's host interface card (P/N AOC-SLG3-4X4P)
to the first set of ports*. For each host, the top cable from the interface card (port A) must be
plugged into port A on the system, and the bottom cable from the interface card (port B) must
be plugged into port B on the system. To support additional hosts, connect PCI-E cables to
the subsequent ports. If using only two hosts, connect each host to a different PCI-E switch
for improved performance (see Figure 3-5).
The following diagrams show three potential configurations for the SSG-136R-NR32JBF: A
single server with multiple interface cards and dual PCI-E x8 cables, four servers with dual
PCI-E x8 cables, and eight servers with single PCI-E x8 cables.
