Data Center Network Components
The terms front-end network and back-end network define the devices that comprise the
infrastructure of the data center and their general role. The front-end network is the IP routing and
switching environment. It provides client-to-server, server-to-server, and server-to-storage network
connectivity. The back-end network supports the SAN fabric and connectivity between servers and
other storage devices such as storage arrays and tape drives.
