How are the clusters networked?
Every server in the cluster is interlinked with others via a Custer Fabric Switch. Under the constant control of Cluster Controller, CFS acts as a local gatekeeper making sure that no single server unfairly hogs the access capacity. Each CFS switch has two dedicated 100Mbit/sec uplinks into the Customer Attach Switches, which in turn connect via dedicated Gigabit links to the core switching infrastructure.
