Note
A Fibre Channel switch is required only if there will be
more devices (client computer or VTraks) connecting to
the SAN than available Fibre Channel ports on the head
unit. A dual controller A-Class unit has 8 Fibre Channel
ports, a single controller unit has 4 Fibre Channel ports.
The Fibre Channel data path minimum requirements are:

Each VTrak A3800 controller is equipped with four 8Gb Fibre Channel ports. The controllers function as an
Active/Active redundant pair in regards to the Fibre Channel data paths, therefore I/O performance to the SAN
increases as more ports are used.
