Switches

I am building an advanced network in a big building which will be used by desktop/printers and backend thin servers, which requires high-available network and consume high bandwidth all this thru categorie 6 cables (RJ-45).

The idea is to build different path with optical fibers and to connect each part of the building with it's own optical fiber to the server room (where we run Microsoft company network servers, SAN, backup, and external access) using a 10/100/1000 switch and optical fiber for long distance.

So I though about using switches which have at least :

48 ports 10/100/1000 (auto negociation)
4 ports 10 gE

for now I will not use many features but with time I could create some trunk, and use some advanced *routing* (switching) features.

As the budget is also not unlimited, I thought about buying :

Edge switch :
§ HP ProCurve 2900-48G J9050A [url]

with X2 extension HP ProCurve 10-GbE X2-SC SR Optic J8436A [url]

Core switch :
§ HP ProCurve 6400cl J8433A [url]

As I am studying any network vendor (but not such as 3com, netgear, dlink, linksys), but more such as HP, Extreme, Cisco, Foundry I am opended to your model ideas for me needs!
