General fabric and switch arrangement

  1. There are two distinct fabrics - fc0* and fc1* - each composed of three interlinked QLogic SANbox 5600 switches.
  2. Each switch has 16 1/2/4-Gb/s fibre channel ports to which clients (servers and disc arrays) are connected, and 4 10-Gb/s XPAK switch interlink ports.
  3. The switch interlinks are arranged as follows:

  4. For multipath redundancy, each client (i.e. each server and disc array) should be connected to both fabrics.

Notes:

  1. Machines marked with a '†' are currently fitted with a single fibre port only; they cannot be set up for multipathing.
  2. 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."
