Chassis and adapters

The I/O modules are installed in I/O bays in the rear of the Flex System Chassis, as shown in the following
figure. I/O modules are typically installed in pairs because ports on the I/O adapters that are installed in the
compute nodes are routed to two I/O bays for redundancy and performance.
Figure 3. Location of the I/O bays in the Flex System Chassis
The SI4091 interconnect modules can be installed in bays 1, 2, 3, and 4 of the Flex System chassis. A
supported adapter must be installed in the corresponding slot of the compute node. Although an adapter can
use up to four ports to connect to the respective I/O module bay, the SI4091 can use only one of the four ports.
In compute nodes that have an integrated dual-port 10 GbE network interface controller (NIC), NIC ports are
routed to bays 1 and 2 with a specialized periscope connector (the adapter card is not required). However, the
periscope connector can be replaced with the adapter when needed. In such a case, integrated NIC is
disabled.
The following table shows compatibility information for the SI4091 and Flex System chassis.
