I am trying to build switch redudndany for my server farm. I have Rack mount servers and blade servers that will be connecting to the switch. The Nics on the servers are teamed and there is redundant switch modules from the blades. I am looking into 2 48-ports 3750G switches to build a stack. I have 2 Cisco 2800 GB routers . I will be connecting to 2 different service providers to redundancy.
What is the best design.
