Patent ID: 7120821

Claim:
A system where a cluster of servers constitute a multiplicity of cluster nodes which are all connected to each other to service multiple PC users via a public network comprising: (a) shared storage means virtually providing a disk resource (Quorum) of stored data, said means being seen as a single quorum repository of a Microsoft Cluster Service Program; (b) local quorum disk resource means which are positioned in each node of said cluster of servers and which operate as a single quorum; (c) means to automatically synchronize the remaining nodes of the cluster when a node is disconnected or inoperative including: (c1) means to reorganize said cluster nodes when the operable node count falls below 50% of the total node count; (d) means to convert said multiplicity of cluster nodes into a single node with its own local quorum disk resource including: (d1) means to sense a network outage which severs said cluster into two partitions; (d2) means to enable the remaining group holding the majority of nodes to continue in operable activity; (d3) means to automatically take off-line the non-majority group of nodes; (e) means to troubleshoot said single node to find the cause of its inoperability, said means including: (e1) means to test the activation signal common to each mode; (e2) means to test the storage capability of each node; (e3) means to test the remote processing capability of each node.
