  • Probe system for replication monitoring
    Patent number: 8886603
    Abstract: A ProbeSystem for one or more Replicas is disclosed. For each replica, the Probe System includes a ProbeHead that updates a Head field in a Target Record pertaining to the Replica and a ProbeEcho that updates an Echo field in the TargetRecord. The Head field includes a time stamp and an epoch value. The Echo field includes a latency value and an epoch value. The fields are such that, during reporting, the ProbeHead can analyze the TargetRecord for the replica to determine the latency between one or more paths between the Replica and other Replicas. The ProbeSystem has a peer-to-peer shared nothing architecture and applies to a large class of high-replica, distributed and high-scale cloud storage systems and services.

  • Method and system for work load balancing
    Patent number: 8661136
    Abstract: Method, system, and programs for balancing work load in a distributed system. A plurality of multi-dimensional load metrics are received from a plurality of resource units in the distributed system. Based on the received plurality of multi-dimensional load metrics and a global statistical load model, a load deviance for each resource unit is computed. The plurality of resource units in the distributed system are then ranked based on the load deviance of each resource unit. At least one load balancing action is further determined based on the ranked resource units and at least one load balancing policy.
