KB Fibre Channel
General fabric and switch arrangement
- There are two distinct fabrics, each composed of one (only!) QLogic SANbox 5800 switch.
- Each switch has 20 2/4/8-Gb/s fibre channel ports to which clients (servers and disc arrays) are connected, and 4 10-Gb/s XPAK switch interlink ports. None of the interlinks are currently used.
- For optimal multipath redundancy, each client server and disc array should be connected to both fabrics.

- Machines marked with a '†' are currently fitted with a single fibre port only; they cannot be set up for multipathing.
- neilb: "Where I've added a port ie p[012], the number is as indicated on the hardware. Note that some hardware is indexed from 0 and others from 1, eg the Dell servers label them port 1 and port 2, but the Evo's and Nexsan boxes label them host 0 and host1."
- 'NC' means that the named machine has been cabled to the switch port, but the cable is not currently connected at the machine end. This should only happen if/when a machine has been physically removed for maintenance of some kind.
