When it comes time that you need 10G, there may/will be other fun options, and your needs may be totally different anyway. In the meantime, using a 4900M chassis with twin-gig ports seems like a waste. > What the 3750Gs - I would pick the "G" over the E/10GB until you need 10 > GB ... the price will have dropped by then - > is an clustered switch stack that you can run redundant etherchannels to ; > one link to one 3750, one link to the other. If you can still get 3560G/3750Gs. (Well, you can, used/refurb. I have a stack of 3560Gs I'll sell you!) > Save your money until you need [ unless you are going to run 10GB to 10GB > links where a single client to server connection will exceed 1 GB you can > just as easily port channel a bunch of 1 GB links and get almost the same > effect. Agreed. It doesn't sound like you need 10G. If you don't care about microsecond latency and don't have a lot of gig-connected servers screaming at each other at wire speed (in which case you might end up in a situation where two full-bore streams map onto the same gig port), etherchannel will do you fine. You could probably use a pair of 3560Gs for your core and get away with it, without having to spend any real money. I wouldn't actually stack the cores - too easy for one to take out the other via the stack cable... but that's a personal preference. The other issue is that cat4948s/4900Ms are in short supply nationwide, at least according to my supplier (and a quick look at ebay) - they appear to be going like hotcakes. I actually had to wait a couple weeks for the 4900M I just ordered, and I'm getting offers on my 4948Es that are WAY higher than you'd think for used equipment. (On the other hand, if you need to go with Cisco and want something with < 15usec switching latency, your choices are fairly limited - cat4k or Nexus - and one of those is a lot cheaper than the other...) If you _need_ to buy now once and for all, then you've got a problem. But if you don't, don't. _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
