I'm designing an office LAN that has 4 floors and a comms room. I require 200 x 1Gbps PoE ports per floor with 10Gbps fibre connections back to the core located in the comms room.
I'm thinking of using Cisco 2960X 48 port stack switches with 10Gb SFP+ uplinks on each floor and a 2 x 3850 in switch stack in the core, the 3850s will each have 4 x 10GB modules and dual PSUs. Each 2960 stack will then uplink to the core using 2 x 10Gbps links.
Is the 3850 suitable for this size of deployment? I have looked at using two 4500 switches in the core but its a lot more costly even with a single chassis and dual SUPs.
The 4 port 10Gig modules are designed to be the uplink ports for the 3850 switches and not the aggregation point. Your design can work but most likely you run to so some sort of performance issues.
If the cost is an issue for you not to invest in better fiber switches like the 4500-x, than why even use 10Gigs as uplinks. I suggest you get 2 "WS-C3850-12S-S" switches and use one gig fiber as your uplinks. Also think of 10Gig optics cost vs 1Gig optics. 10Gig optics are at least 2x more expensive.
I highly recommend going with the 2960-X and 3850 for the latest models and meeting your required port density and fiber connections. Earlier replies has a point as well, we need to better understand your requirements (to see if this is a suitable deployment.
The Cisco 3850 supports converged wired and wireless network (integrated controller), which is a good investment for sizing your wireless network.
Let me know if you have additional concerns or e-mail (firstname.lastname@example.org) me directly. Kind regards.
