Ed,

Thanks for the great information.

"Seems like the chicken will come home to roost in a positive way for SUN as this theme was pounded home by alot of Speakers as well as SSB reps. SUN turnkey solution the equivilent of a SAN in a box."

I hope everyone there saw the slide Ancor has in their presentation of two 64 port switches labeled "SAN A" and "SAN B" compared with the equivalent SANs made from 20 - 16 port switches.

"10Gig Ethernet was pooh poohed by storage vendors as more smoke then fire and again years away from working out problems to make storage viable on GE which took FC that long to work out."

The other practical issue with GE that Dr. R. reminded me of the other day was the usuable bandwidth. We know that both Ancor and Brocade SANs can probably run at a bandwidth of 80 Mb/s. It is doubtful that 1Gbps GE can run at the speed on the LAN (my guess is about 60 -70% of that figure). The move to SANs is in part to unload the LAN side and the push to 10Gbps seems fueled by the fact that they need it on the LAN side more than anything else, especially as the bandwidth in the WAN increases tremendously.

Are there any engineers out there with data on high performance 1.5 Gbps GE? What is the maximal sustained data rate you can expect?
