US Patent 7571344: Ensuring data integrity in network memory
US 7571344 ยท granted 2009-08-04
Abstract
A first appliance for ensuring data integrity in network memory is disclosed. The first appliance includes a processor and a communications interface that communicates over a communication network with a second appliance of the network memory. The processor determines whether reconciliation between a first peer state information in the first appliance and a second peer state information in the second appliance is needed. The first peer state information and the second peer state information track the status of data in the network memory. The processor determines an action to reconcile the first peer state information with the second peer state information based on a positive determination that the reconciliation is needed. The processor then performs the action to reconcile the first peer state information with the second peer state information.
