Server pool for clustered system
First Claim
1. A computer system, comprising:
- a plurality of interdependent processors for operating a common set of applications, each interdependent processor executing an independent operating system image without sharing file system state information, each interdependent processor having a network access card with a first network connection and a second network connection;
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
a director coupled to both the first and second active backplanes, the director being adapted to recognize a service request from one of the plurality of interdependent processors as being associated with a pool of servers, the service request including an indicator pointing to the pool of servers.

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.

13. A method for operating a computer system, comprising:
-
executing an independent operating system image without sharing file system state information by each processor in a group of interdependent processors, each interdependent processor having a network access card with a first network connection and a second network connection;
transferring data on either a first active backplane coupled to each first network connection of each processor or 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
recognizing a service request from one of the plurality of interdependent processors as being associated with a pool of servers, the service request including an indicator pointing to the pool of servers. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
