For most purposes I continue to spec simple 100baseT for server<-->switch connects, 10baseT for normal clients, and quad-100baseT etherchannel for the occasional really badass server (e.g. a NetApp). > I don't have a 10gig-E system, but I wonder about going there when > I can't even get gig-E to work efficiently. Well, that's you --- and me too. But that's sure not most customers. Even some folks whose expertise I generally respect have completely bought into gig-E, and try to apply it for host connects, without attempting to measure whether the host is capable of saturating even 100BaseT with their traffic. > If vendors want to sell 10gig-E they should be concerned about > exactly this point. Not true, no more than the belief that if vendors wanna be able to charge more for GHz CPUs, they must have sufficiently balanced systems so those CPUs really get work done faster than the previous generation. Turns out they don't; the vast majority, that manufacturers care about, that determine the success or failure of a product or marketing strategy, those masses don't care about measured performance, they care about bigger numbers and proud boasts.

I disagree once again. Joe Enterprise buys whatever the last salescritter to buy him lunch-with-drinks tells him to buy. No other explanation for all those "SANS" they're inflicting upon themselves, poor boobs. Maybe Joe dot-com will be forced to get a little smarter if his Wall St. bank stays cagey, but I wouldn't bet on that outcome; I figure it won't be long before the dotcoms once again have far, far more money than clue to use it, and so buy whatever sounds gaudiest. - -Bennett -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.0 (GNU/Linux) Comment: For info see http://www.gnupg.org iD8DBQE5TlIZL6KAps40sTYRAledAJ9YVq5w3IviRuqbm3c72WmRV1ENRwCeO6yf jfcowHOYE+59VUqxpYF18lg= =UL3s -----END PGP SIGNATURE-----
