This article focuses on datacenter consolidation architecture. Datacenter consolidation and Web-centric computing's goals of reducing the growth and cost of servers put new demands on networks. Network managers can no longer view consolidation as a "server" and "application" group problem. Additionally, end users are always seeking faster response time and demanding the network solve the problem. It is unacceptable for the network manager to deflect blame by pinning the problem on the application rather than the network. For performance or availability reasons, applications no longer could reside on just one server; large enterprise applications and the new Web applications required multiple servers. The proxy function is the key that allows the AFE to lessen the burden on the server. It an AFE is going to provide advanced security, offload the server and accelerate the application, it is going to have to get more involved with the TCP connection. Server offload means that not every request is actually going to make it to the server.
