Well, one of my amanda clients does two dumps in parallel over 100BaseT at >=3MB/s dumper rate (each) every single night. Does that count? :-) 2*3MB/s -> 48 Mbit/s. Minimum. They average more like 3.5MB/s each. As long as the packet size is reasonable, any competently implemented 10BaseT or 100BaseT link can gracefully handle sustained payload peaks up to 90% of wire speed, no problem. I plan on 50% wire speed utilization for my 11pm-5am backup period, and I consider that very conservative. 1000BaseT is different, at least with stock interoperable HW and SW; the 1500-byte packet size limits you to something like 50-65% of wire speed. You need semi-proprietary, not-completely interoperable jumbo packet HW and SW to go faster. > As always, your mileage may vary ... Yup! -- Jay Lessert [EMAIL PROTECTED] Accelerant Networks Inc.
