Daler, Thanks for the Byte link. A good overview of what is available and some of the biases against FC. I would highly recommend it to everyone investing in FC. Some of the concerns about integration with legacy systems seem to ignore Ancor solutions. For example this excerpt: "Another big problem with Fibre Channel is its lack of integration with legacy storage devices and networks, notes Kon Leong, president of GigaLabs, which is a manufacturer of Ethernet switches. For instance, there is no Fibre Channel-to-Ethernet bridge, and you need a SCSI-to-Fibre Channel bridge to use current SCSI devices on a Fibre Channel network." Seems to ignore this Ancor solution: ancor.com But then again, Gigalabs is currently trying to promote their own switched SCSI solution. George D.

Daler, I found these quotes from the Byte article interesting. My comments follow each quote. "Switching offers more fault tolerance (because switches can isolate malfunctioning devices) and higher performance." I think this is what we have been saying for a long time. <g> "There's nothing else that can handle the combination of storage and network as well as Fibre Channel," says Friedmann. "We are hearing a lot about Gigabit Ethernet. But it doesn't talk directly to storage, and it's half the speed of Fibre Channel. More important, Ethernet is about four times the processor load." I think this is what we have been saying for a long time. <g> "Another big problem with Fibre Channel is its lack of integration with legacy storage devices and networks, notes Kon Leong, president of GigaLabs, which is a manufacturer of Ethernet switches. For instance, there is no Fibre Channel-to-Ethernet bridge, and you need a SCSI-to-Fibre Channel bridge to use current SCSI devices on a Fibre Channel network." I have been after Ancor for a long time to do this. <g> "Furthermore, three years from now, Ethernet chips and Fibre Channel chips will cost about the same for comparable speeds, predicts Ed Frymoyer, president of EMF Associates (Half Moon Bay, CA), a consultancy specializing in Fibre Channel. On a cost-per-Mbps basis, Fibre Channel is already less expensive than Gigabit Ethernet today, he adds. Frymoyer also says that he expects three Fibre Channel-to-Ethernet bridges within a year." Maybe Ancor will have one of these bridges. "Another option for high-speed clustering is ServerNet, from Tandem/Compaq, a full-duplex 40-Mbps interconnect optimized for clustering." This is the first time I have seen the speed of ServerNet quoted. It is not nearly as fast as I would have guessed. Craig
