Multistage Topology

Multistage Examples

Figures 5-3through 5-5are examples of Multistage topology using SANbox-16 Switch chassis.

Figure 5-3 SANbox-16 Multistage with one T_Port link from each IO/T chassis

Figure 5-3shows a Multistage Switch built from SANbox-16 chassis. One T_Port on each IO/T chassis (the minimum) connects to the CC chassis. This provides 100 MBytes of bandwidth between each IO/T chassis and no failover in case a T_Port fails. Note that any IO/T chassis can communicate with any other IO/T chassis with just three chassis hops (counting the source and destination chassis.

There are 15 user ports remaining on each IO/T chassis. All user ports may be F, FL, SL, or TL_Ports.
