Abstract

A computer system includes a plurality of interdependent processors for operating a common set of applications. Each interdependent processor executes an independent operating system image without sharing file system state information. Each interdependent processor has a network access card with a first network connection and a second network connection. The computer system includes a first active backplane coupled to each first network connection of each processor; a second active backplane coupled to each second network connection of each processor, the second active backplane operating in lieu of the first active backplane in case of a fail-over; and one or more directors coupled to the first and second active backplanes, each of the one or more directors load-balancing requests directed at a plurality of servers.
