George, Herr Doktor Rauechle may have answered my question regarding why not GE in the SAN: nwfusion.com Third, Desmond wasn't satisfied that Gigabit Ethernet's 1.5K-byte packet size is a problem in the SAN. Such a small packet size induces a large processor load because of the fact that the processor has to service so many more interrupts. (Every time a packet is received from the network an interrupt is sent to the processor. Obviously a 1.5K-byte packet stream interrupts the processor roughly 85,000 times more often than a Fibre Channel 128M-byte packet stream.) That leaves less processor bandwidth available for other applications. One workaround would be to use 2 K-byte frames and implement sequencing, but the resulting GE SAN would be incompatible with the GE LAN, voiding the benefits of standardization. Sounds good to me. Much more to learn. Greg
