OmniPort Integrated Hub Interconnection
The integrated hub capabilities of the Patent pending OmniPort Fibre Channel I/O port
allows for simple cascading of multiple Fibre Channel devices. Standard duplex HSSDC
copper and SC Duplex fibre optic cabling is supported. Three modes of operation
include integrated hub, redundant point to point and redundant arbitrated loop (JBOD
connection).

Redundant Arbitrated Loop (RAID/JBOD connection)
With redundant connections from the VMFC-2X00 to the RAID/JBOD, the OmniPort
automatically switches to the alternate loop when the current loop fails. The alternate
loop is looped back to the disk array. The OmniPort will park on the last known good
loop and only switch upon failure detection. Redundant connections improve the MTBF
of the system.
