it's equivalent to the 4500 series... but the hp had a bigger fabric & lower latency... plus a butt-load more configurability/options ew, 4500 series yuck ... SEE! hp > cisco for that type of switch. http://www.internetworkpro.org/wiki/Criticism_of_the_Catalyst_4500 <--- suck the 4500 DO suck... this I know... but for the size/module ness/etc... the HP procurve 4100 series kicked it's ass. Eimsr: what kind of interfaces are you using? anyhow... I am using it for 12-vlans... gigabit to servers and each site... and 10/100 for some LAN connections. ah, you should use 3750E's for that BSDaemon^|work2... I would have... but the 3750E's didn't have as big of a fabric. too much "daisy-chaining" umm whats the fabric on the HP procurve? 8gbps cool. 3750s are 128Gbps with a 32Gbps Stackwise+ ring. fibber. hahaha riiight
