A hub for a fiber channel arbitrated loop is disclosed. The hub comprises
a switching device including a matrix of switches connected by a
plurality of signal lines, each signal line being electrically connected
to at least one switch. The hub is operable to selectively connect and
disconnect one signal line from at least one other signal line, at least
some of the signal lines being operatively connectable to respective
devices comprising the fiber-channel arbitrated loop. The switching
device is operatively configurable to selectively open and close the
switches to arrange the devices on the fiber-channel arbitrated loop.
