George, <<<Is there any reason why the ATM switches here couldn't be replaced with FC switches or a switched fabric? It would greatly increase the FC Lan diameter, and some of these devices support 80 channels over a single fibre ( 2 fibres for duplex ). This would mean you could mux all the channels from 2, 64 port non-blocking fabrics (64 channels muxed) over a single fibre to an equal number of FC ports at the other end. The advantages are two-fold, greatly increased distances (up to 150 km instead of the FC limit of 10 km) and savings on fiber - 2 opposed to 128. That would have to be balanced against the cost of the multiplexer.>>> Didn't check in until today, sorry. After examining the slide, my impression is that FC switches could indeed replace ATM switches if the distance between end points(i.e. Token devices, FDDI devices, etc.) to the 'ATM' layer(i.e. ATM switches) are within the distance limit of FC. In addition, the distance between the the 'ATM' layer and the 'SONET' layer has to be within the FC distance limit. I would say it's highly unlikely for the time being while all attensions are given to SAN. FC IMO is not acitively pursuing the WAN issue yet. KJ
