Nice post, Gus! Is McData's market share in the Directors because of their expertise in FICON? What do you see as the strengths and weakness' of the Q-Logic/Inrange Directors and the McData Directors? You have a great deal of technical knowledge. I would be curious to get your perspective.

Joe

Gus,

You are a godsend, a saint, and a scholar. Your sins, however, are between you and your soul
(not that I've noticed any [sins, that is]).

I think that the general trend towards all IP networks is pretty clear. What is not clear, IMO, especially among the plethora of nitwit pundits, is that so-called "native IP" will always have throuhgput constraints relative to IP's "native" transport.

IP runs faster on faster wires. IP over optical Sonet pushes 10Gbs at OC-192.
IP over FC will move at FC speeds as they develop.
IP protocol engines over InfiniBand will scream.

SCSI over IP will never exceed the max SCSI drive throughput of the industry estimated top of 320MBs. What good is a fast pipe for a slow trickle? Both SCSI over IP and EtherStorage are strictly bargain basement Brand-X solutions and cannot play in the HA low latency mission critical high end of storage networks. IBM and Agilent's announced new 2Gbs FC disk controllers bespeaks a time when faster FC drives will replace slower SCSI drives in the enterprise.

When I think of iSCSI, iScream at the unmitigated crapola being foisted upon the investing public.

Thanks for your unstinting efforts to clear away some of the stink.

Douglas
