Dual-controller SBOD Connection
1. In the configuration below, CH4 and CH5 are manually configured as
drive expansion channels. CH2 and CH3 can also be used for drive loop
extension.
2. The expansion ports are then connected to the dual-controller version of
F16F-J4000-R SBODs. These channels form a drive-side dual-loop
across the expansion enclosures.
3. Each enclosure should be assigned with a unique enclosure ID using the
DIP switches on the rear panel.
4. The onboard hub is "enabled" on the CH4 and CH5 channels. If the
onboard hub is disabled, you will need FC switches for fault-tolerant
links to expansion enclosures.
