RE: Time for new core switches

RE: Time for new core switches
Haven't used Enterasys for a long time but one thing I really liked about them was that each line in the config was numbered.

Re: Time for new core switches
I have the same set of switches here and they have been rock solid for over 7 years. I plan on moving forward next year and have been looking at HP and Force10.

Looking at my options, what speeds are you now using for your core switches: 1 GB, 10, 100? I can tell you about our needs, but your needs may be entirely different. There's no generic answer to this one. But as food for thought: We're 100 meg to most desktops. 1 gig to servers, between switches, and to heavy users like IT and CAD people. Link aggregation (2 x 1 gig) between two switches in the server room. That meets our needs for now. For new construction, I'm having them run CAT6A between switches, to allow for 10 gig in the future. But I'm only running 1 gig on it presently. I don't think we will need more than that in the foreseeable future. I do have several SANS that are connected to the core. SANs, or disk I/O of any kind, are one of the things that benefits the most from higher speed links. Since such uses are often in one server room, very high speed links are also a lot more practical. (As opposed to a whole building, where both distance and old wiring often hinder speeds = 1 gig). I haven't run any port stats yet but I will. You should start there. :-) What about port size? Each of these switches has 24 ports. I could continue with smaller switches or look for a few switches with many ports. This depends mostly on the total port count you need. If you only need, say, 50 to 100 ports, a modular chassis may well be overkill. Stacking smaller switches gives you some fault-tolerance: If you loose an entire switch, you can move critical stuff to the remaining switches and drop less important nodes. Or keep an entire spare switch on-hand. On the downside, stacking smaller switches may make management harder, as now you have to deal with several entities rather than one big chassis. It may also limit your bandwidth: Most modular chassis platforms offer more backplane bandwidth than you can get using interconnect cables on stacked switches. Chassis may also be more space and power efficient. I recall seeing a Foundry core switch a few years ago and I think it had a few hundred ports. There are switch platforms that support 1000 ports in a single chassis. It's all about what you need. -- Ben ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/ ~ --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to listmana...@lyris.sunbeltsoftware.com with the body: unsubscribe ntsysadmin
