data or management.

There is also a serial port console you can hook (we use
cyclades terminal servers)  and a RLM remote management
port that uses a LAN (we have a physicially seperate management
LAN).  the RLM is very cool, you can do remote power on/off,
lots of out-of-band control and console redirection.

if you have a cluster, you need a minimum of two disk FC ports.
one for the primary, and one for the failover partner.

Depending on performance needs and the number of shelves,
you may want to use more FC for disk shelves.

If you need more ports, install some x2050 FC adapters in
the PCI cage for the disks, and use the on-board for
the initiator ports.

also, depending on the speed of your tape drives, and
how many, one should be plenty to feed tape devices for
backup.
