Possible Icl Configurations; Qsfp Cable Connections For Two San768B-2 - IBM System Storage SAN384B-2 Installation, Service And User Manual

Possible ICL configurations

Figure 47 illustrates one possible QSFP cable configuration between two
SAN384B-2 or SAN768B-2 chassis. Each of two cores in one chassis should be
interconnected with each of two cores in the second chassis. This provides for
inter-chassis link (ICL) trunking between chassis, ensuring redundancy. Parallel
connections between core blades are recommended.

SAN384B-2 and SAN768B-2 chassis can be connected in a core/edge configuration.
Figure 48 on page 97 shows two core and four edge chassis. Although only
SAN768B-2 chassis are shown in the figure, the chassis can be any combination of
SAN384B-2 and SAN768B-2. The cabling scheme should follow the parallel
example shown in the Figure 47. Each line in the Figure 48 on page 97 actually
represents four cables running between the chassis.
