which is connected to a management station. The management station is then
connected out-of-band, via an Ethernet network, back to the second fibre channel
I/O path.
Note: Do not connect the DS4800 Storage Subsystem Ethernet ports to a public
network or public subnet. It is strongly recommended that you create a
private network between the DS4800 Storage Subsystem and the
management station.
Fibre channel connections
The storage subsystem fibre channel connection consists of up to four host
fibre-channel loops and a redundant drive fibre-channel loop. The host fibre-channel
loops provide the fibre path for host attachment. They can consist of fibre-channel
