We currently have a stack of 5 3750s which operate as combined core and distribution switches (for the building where our data center is located). The breakdown is 2 WS-C3750G-24TS and 3 WS-C3750-48TS. This gives us 212 ports, of which roughly 140 are currently in use.
We've received approval to upgrade some of our network hardware. The basic plan is to replace this stack, and push those switches out to branch locations to replace some EOL models (2950, 3524).
We're anticipating the need for increased bandwidth in the coming year, due to implementation of a SAN array, as well as a blade chassis (with integrated Cisco 3020s, of course :)).
Should I be looking at a chassis, or possibly going to something like the 3750E series and sticking with the stack config?
