<p>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 (146) coupled to each first network connection of each processor; a second active backplane (148) coupled to each second network connection of each processor, the second active backplane (148) operating in lieu of the first active backplane (146) 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 (150 and 152).</p> |
