i want to build a data centre with switches i`ve got on the shelf.
for the access and distribution layer the different 2900 and 3500 models will do fine.
the data centre consists of:
1 cabinet containing a dell blade m1000e cassis incl. redundant cisco fibre switchmodules, 1 emc clarion 4 tb SAN ,with 2 fibre san switches.
1 cabinet containing a couple of hp dl320,360,580 servers.
2 cabinets containing Bull database servers
if i take the 3750e as a standard for all the different layers this will work efficiently?
For your small environment, Yes.
over time the other switches will be updated i can have 1 in stock for direct hardware replacement.
That's actually a pretty good idea.
So, the bulk of the money is going towards the server infrastructure but in order for the servers to communicate they need a robust switching topology.
I recommend getting a pair of 3750-E - stack them for redundancy - they will function as a collapse core/access-switch for this environment.
You are planning to build a DataCenter with End Of Life equipment? I don't think that's a good idea.
In addition to that, all the switches you've listed are targeted for the access layer, not for the Core of the network.
