Fibre Channel SAN – No Single Point of Failure

An FC SAN with no single point of failure (NSPF) requires:

• An FC HBA card in each host PC or server

• An SFP transceiver for each connected FC port on the subsystem

• Two SFF-8088 4X to SFF-8088 4X SAS external cables for each JBOD unit

• Two FC switches

• A network switch

Data Path

To establish the data path:

1. Connect an FC cable between an FC data port on the left RAID controller

and one of the FC switches.

See page 32, Figure 15.

2. Connect an FC cable between an FC data port on the left RAID controller

and the other FC switch.

3. Connect an FC cable between an FC data port on the right RAID controller

and one of the FC switches.

4. Connect an FC cable between an FC data port on the right RAID controller

and the other FC switch.

5. Connect FC cables between one of the FC switches and the FC HBA cards

in both of the host PCs or servers.

6. Connect FC cables between the other FC switch and the FC HBA cards in

both of the host PCs or servers.

If you have multiple VTrak subsystems, repeat steps 1 through 6 as required.
