Figure 3-6 Connecting the two x440s together in a 16-way configuration
The two x440s are connected through the scalability port on each SMP
Expansion Module and require the installation of four 3.5 m Remote I/O cables
(part number 31P6102) to complete the configuration.
Key points relating to SMP Expansion Module cabling:
The SMP Expansion Module ports cannot currently be used as high-speed
interconnects for clustering purposes.
The connections do not offer redundancy. If a connection is lost, the server
will shut down or restart depending on your system’s configuration.
Tip: These four additional cables are the same as the ones used to connect
the RXE-100 Remote Expansion Enclosure.
