Proc by to neslo? je to jen otazka patricneho HW. Na SUNu s trochou
dobre vule rozbehate Sun SOC/Sbus a SOC+ (SOCAL) a o nich
(vytazek z kernelsourcetree/drivers/fc4/fc.c):

 * There are two kinds of Fibre Channel adapters used in Linux.
 * the adapter is "smart" and does all FC bookkeeping by itself
 * just presents a standard SCSI interface to the operating
 * (that's e.g. the case with Qlogic FC cards), or leaves most of the
 * bookkeeping to the OS (e.g. soc, socal). Drivers for the former
 * will look like normal SCSI drivers (with the exception of max_id will
 * usually 127), the latter on the other side allows SCSI, IP over FC
and other 
 * protocols. This driver tree is for the latter

Ma to asi 1Gb.... Staci? :-)
