摘要： An apparatus, system, and method are disclosed for cache synchronization within a multi-tier system having multiple client-server relationships. The apparatus includes a pre-synchronization module, a locking module, and a synchronization module. The pre-synchronization module receives a pre-synchronization call from an upstream node coupled to a first downstream node. The locking module locks a first cache coupled to the first downstream node in response to a synchronization call from the upstream node. The synchronization module synchronizes source data on the upstream node with cached data on the first cache. The apparatus also may include a post-synchronization module to perform any necessary cleanup activities. Advantageously, the apparatus, system, and method reduce the likelihood of a system deadlock due to premature locking of the first downstream cache, which prevents a subsequent downstream cache from synchronizing with the first cache.

摘要： A method, apparatus and program storage device for providing failover for continuous or near-continuous availability in an N-way logical shared-nothing cluster system is disclosed. Cluster application data space partitions are assigned to each node in the cluster and each node's or server software's internal architecture is partitioned in accordance with the application data partitions assigned to the node. Cluster-integrity protection is performed. A failover and recovery protocol is performed based upon the assigned partitions and the partitioned and bound internal architecture. Containment of the impact of failure is provided such that most of the application data space partitions are not impacted. Affected partition sets are failed over fast and in constant time and so actual load on the surviving nodes does not affect failover duration. When shared storage is not provided, synchronous log replication may be used to facilitate failover and log-based recovery.

摘要： The acquisition of a lock among nodes of a divided cluster is disclosed. A method is performable by each of at least one node of the cluster. A node waits for a delay corresponding to its identifier. The node asserts intent to acquire the lock by writing its identifier to X and Y variables where another node has failed to acquire the lock. The node waits for another node to acquire the lock where the other node has written to X, and proceeds where Y remains equal to its own identifier. The node waits for another node to acquire the lock where the other node has written to a Z variable, and writes its own identifier to Z and proceeds where the other node has failed. The node writes a value to Y indicating that it is acquiring the lock, and maintains acquisition by periodically writing to Z.

摘要： A method and system for resetting a network device. Specifically, in one embodiment, a method is disclosed for upgrading and/or reloading software for a network device with minimal disruption. The method begins by separating operations associated with layer two of an International Standardization Organization Open Systems Interconnect (ISO/OSI) reference model from other layers in the ISO/OSI reference model in a network device. Then, the software operations in layer two of the network device are reset. The software operations are reset while maintaining continuity for a communication session between the network device and other network devices coupled together through a network. Thereafter, for minimal disruption, execution of the software operations is recovered at layer two before continuity of the communication session s terminated.

摘要： In an embodiment, a system and method which monitors a signaling plane for error events among one or more network nodes in a converged network. The system and method classifies and calculates, based on user defined parameters, a threshold value or percentage of error events which occur within a desired amount of time and automatically triggers an alert in the network that a potential network connectivity problem exists in the transport plane. In an embodiment, the trigger automatically initiates troubleshooting procedures to solve the network connectivity problem.

摘要： A hierarchical packaging model of self-describing plugin modules and packages of plugin modules. Identifiers are assigned to each package of plugin modules in a hierarchical relationship so that adjacently identified packages are backward compatible. The package identifiers are maintained internally to the package. Similarly, identifying data of a plugin module is maintained internally within the namespace of the respective module. Interdependency of plugin modules is determined by comparison of data maintained in the namespace of each module.

摘要： An apparatus, system, and method are provided for verified fencing of a rogue node within a cluster. The apparatus may include an identification module, a shutdown module, and a confirmation module. The identification module detects a cluster partition and identifies a rogue node with a cluster. The shutdown module sends a shutdown message to the rogue node using a message repository shared by the rogue node and the cluster. The shutdown message may optionally permit the rogue node to preserve latent I/O data prior to shutting down. The confirmation module receives a shutdown ACK from the rogue node 206. Preferably, the shutdown ACK is sent just prior to the rogue node actually shutting down.
