Cisco Network Design

I am going to be designing a network around 200 users, 4 vSphere hosts with about 200 VM's total. I have a $25k budget. PoE is required for 3 x 48 ports.

I was thinking..

CORE = 2960XR-I 24x
DIST/ACCESS = 2960X-LP 48x (PoE) x 3
ACCESS/TOR = 2960X-L 48x x 2

Any suggestions?

200 users, I would just use a collapse core design and combine your distribution and core layer using a switch stack.

Also, why does your dist layer have more ports than your access layer. There is no such thing as an distribution/access layer.

For the core layer, you may need a switch that can do layer 3 routing, such as the 3750.  And this network is small enough, that you may not need a distribution layer.

Thank you.  What about stacking? Should I stack the switches?  Would it make sense to purchase SFP+ 10G modules for the uplinks, or should I just stick with SFP 1G and use etherchannel?

I'm concerned that 2Gbps is going to be a bottle neck if a bunch of servers/users are transferring data. Is 10G overkill for this?

If the access layer switches are going to be daisy chained, then you should definitely use stacking.  If the access layer switches can each have their own link back to the distribution or core switch, then I do that, rather than stack them.  10 Gbps links are the norm for server and SAN connections.  1 Gbps is usually sufficient for standard user connections.

 One of the main issues with network wires is that you never have enough.  You run plenty and plan for the worst case but you still end up needing more.  What many people do not realize is with 10BaseT and 100BaseT (but not 1000BaseT) networks you …
