PCI-e Cables
PCI-e cabling is required to connect the SSG-136R-N32JBF to the server node's host interface
card(s). The chassis has four x16 external PCI-e 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 3-9).
The following diagrams show three potential configurations for the SSG-136R-N32JBF: A
single server with multiple interface cards and dual x8 PCI-e cables, four servers with dual
x8 PCI-e cables, and eight servers with single x8 PCI-e cables.
