SANbox-8 Fibre Channel Switch
5-22 Multi-Chassis Fabrics 59008-03 Rev. A Installer’s/User’s Manual
Figure 5-5 SANbox-8 Multistage with Four CC Chassis
Figure 5-5 shows a Multistage Switch built from SANbox-8 chassis. Each of the
eight IO/T chassis has one T_Port connection (the minimum) to each of the four
CC chassis. This provides 400 MBytes of bandwidth between each IO/T chassis
and failover in case T_Ports or CC chassis fail. Each IO/T chassis distributes the
available T_Port access among its user ports. In this case there is a T_Port for each
user port. If a T_Port or CC chassis fails, the chassis re-assigns the user port from
the failed path to another T_Port/CC that is good.
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 four user ports remaining on each IO/T chassis. All user ports may be F,
FL, SL, or TL_Ports.
If you used a SANbox-16 as a Cross-Connect, you could expand this configuration
to 16 IO/T chassis.
