Core switch / Link aggregation
I'm having a bit of an issue here.
Our core switch is just a gigabit 3Com switch, that when it was purchased was good enough to do the the job it was needed for, but now the head of IT has changed his course 4 times in 5 years and the pupils are now editing videos for the course. This means that up to 52 kids could be accessing the same video and editing it at the same time, which slows the network down. We have a 1Gbs link from the fileserver to the core switch, a 1gbs link to the switch that the client PC's are on then a 100mbs link to the client PC's.
I'm thinking of purchasing a decent core switch, something that isn't £250, that we can manage properly. Now ths is where i'm just guessing, so please tell me if i'm wrong, I have been reading about link aggregation, or teaming which ever you want to call it, and was thinking of doing the following.
having our fileserver with 4 nics and team them up to make a 4gbs nic, then team the ports on a switch that our servers connect to to mirror this. Then connecting the server switch to our core switch with a team of at least 4Gbs. I was then thinking of purchasing 2 new 48 port switches for our 2 IT suites and teaming either 2 or 4 ports together and connecting them to the core switch.
So if i'm right it will be like this,
Server -4Gbs- Switch -4Gbs- Core -either 2Gbs or 4Gbs- ICT Suite switch
Does this sound like a plan to help speed things up? Is it possible and will it work?
Also, can anyone recommend some decent switches that I can use for this if it will work? We are running 3Com at the moment, but if all goes well I may be replacing all the switches we have, but the ICT suites are the most important at the moment.
