Sample cabling for the first controller enclosure:
Two SFP I/O cables connect Controller 0A and two more connect Controller 0B to the left I/O switch.
l
Two SFP replication cables connect Controller 0A and two more connect Controller 0B to the center replication switch.

Sample cabling for the second controller enclosure:
Two SFP I/O cables connect Controller 0A and two more connect Controller 0B to the right I/O switch.
l
Two SFP replication cables connect Controller 0A and two more connect Controller 0B to the center replication switch.

To make this as clear as possible, depictions are of a simplified version of four-port controller, where green cables show
replication traffic and blue cables show I/O traffic.
Figure 47 Sample of three switches for co-located controller enclosures, multiple host servers
Co-located replication with single switch and server
In cases where you use a single switch connected to a single host server that is logically functioning as multiple servers, an
example of optimal cabling dedicates a pair of cables connected to each controller for I/O traffic and the other pair connected
to each controller for replication traffic.
Sample cabling for the first controller enclosure:
Two SFP I/O cables connect Controller 0A and two more connect Controller 0B to the switch.
