Cisco core switching sizing and design recommendations

Last Modified: 2012-05-10
I'm trying to get design guidance for appropriately sizing core switches for new customer deployments.  I want someone go through the thought process and math involved in finding the "best fit" recommendation for a new core, based on industry "best practices."  

Let's use the following customer requirements as an example:

- Single campus with 500 total hosts (300 PC's, 200 of them connected through IP phones)
- Gigabit Ethernet access switches, spread across 5 access-closets (100 devices per closet)
- Dual fiber optic (MMF) connectivity between the closets and the core

We're going to go with a redundant core design, and the options are:

- Dual Catalyst 6506's
- Dual Catalyst 4506's
- 3750-X stack

(Please disregard the VSS capability of the 6500's - I want design and sizing guidance based only on port density, bandwidth requirements and oversubscription best practices.)

Explain the process of choosing the appropriate solution, as well as the recommended supervisor if choosing a chassis-based solution.

Thank you!
