   oops, i forgot SAN and NAS. It helps if you can spell SANsurfer
or HBAnyware (these are names of GUI manager programs that
are used to configure Host Bus Adapters, usually PCI expansion
cards that allow communication via fibre cables to a fibre switch
onto a "fabric"--fibre cables going to storage arrays). NAS is
an ethernet, not fabric, equivalent.

   I also forgot to emphasize the networking angle. Start with the
network commands in the /bin directory.
   Ask lots of questions, hopefully to the list.
