Best way to connect servers to 3Com switch stack
Posted on 2006-11-01
I am putting six 3Com 4200G 24port 10/100/1000 switches into a cusomters site in a few weeks. They will be connected in a stack using gigabit stacking modules in the dual-personality port bays. I understand they should be connected in a daisy chain with a link from the top of the stack to the bottom.
I guess my first question is what are the implications of having switches in a stack like this from a bandwidth point of view? I mean you've got 24 devices on one switch but only one cable linking to the next switch. And in a stack of six a packet may have to travel through up to two other switches before arriving at the destination switch. Do the links not create a serious bottle neck? If so, would there be a significant benefit to using say three 48 port switches in this case, so all switches are effectively 'adjacent'. I'm just looking for some general information and observations on this point, it's a question I've had in my mind for quite a while.
The main question was abot connecting servers etc. to this stack, though I feel if the above question is answered I can answer this myself. My thinking here is if the links between switches DO create a serious bottle next then maybe it would make sense to connect say server1 to switch1, server2 to switch2, server3 to switch3, InternetRouter1 to switch4. That way one particular link isn't going to be saturated because it has all the servers and outbound routes on it.
Hopefully it's clear what I'm asking here.
