摘要： An apparatus, system, and method are provided for causing a failed node in a cluster to transfer its outstanding transaction queue to one or more surviving nodes. The heartbeat of the various cluster nodes is used to monitor the nodes within the cluster as the heartbeat is a dedicated link between the cluster nodes. If a failure is detected anywhere within the cluster node (such as a network section, hardware failure, storage device, or interconnections) then a failover procedure will be initiated. The failover procedure includes transferring the transaction queue from the failed node to one or more other nodes within the cluster so that the transactions can be serviced, preferably before a time out period, so that clients are not prompted to re-request the transaction.

摘要： A system and method for failure recovery and failure management in a cluster network is disclosed. Following a failure of a storage enclosure or a communication link failure between storage enclosures, each server node of the network determines whether the server node can access the drives of each logical unit owned by the server node. If the server node cannot access a set of drives of the logical that include an operational set of data, an alternate server node is queried to determine if the alternate server node can access the a set of drives of the logical unit that include an operational set of data.

摘要： A protective circuit compares at least two different signals and asserts a control node toward respective logic states accordingly. At least one of the signals is derived from a voltage on a power rail within a computer or other device. A switching element passes or isolates an enable signal based on the logic state of the control node, enabling or preventing operation of a power supply, accordingly. Central processing units (CPUs) or other elements are protected against electrically caused damage in the event that a fault is detected by the protective circuit.

摘要： A system and method is disclosed for failure recovery and communications in a shared storage system. The shared storage system includes at least two host nodes, each of which includes two ports. Each of the ports of each of the nodes is coupled to input ports of a storage enclosure. The input ports of the storage enclosures are in turn coupled to one another to form communications links between each of the host nodes. When the communications links between the host nodes fail, the host nodes are able to pass configuration information to each other by saving configuration information to a central location in a shared storage, such as a dedicated location in one of the storage drives of the storage enclosure that is directly coupled to both host nodes. The host nodes are able to force their peer nodes to read configuration changes before accessing possibly corrupted data from a previous configuration.

摘要： A system and method for recovering from a server failure in a computer network, wherein the network contains several stand-alone, non-clustered, servers, and a cluster, wherein a clustered server also serves as the spare server, is disclosed. This cluster will have one standby recovery group for each non-clustered server in the computer network. Each recovery group contains the IP address and network name of the associated stand-alone server. The cluster monitors the health of the stand-alone servers, preferably through the use of a heartbeat mechanism. If the cluster detects a failure, it will reassign the LUNs owned by the failing server to the cluster. After the cluster has reassigned the LUNs, it will activate the recovery group containing the IP address and network name of the failing server. Subsequently, the cluster will assume the identity of the failing server and serve its users, until the failing server is repaired or replaced.
摘要翻译：一种用于从计算机网络中的服务器故障中恢复的系统和方法，其中所述网络包含若干独立的，非集群的服务器，以及其中集群服务器还用作备用服务器的集群。该群集将为计算机网络中的每个非群集服务器设置一个备用恢复组。每个恢复组包含相关联的独立服务器的IP地址和网络名称。集群监视独立服务器的运行状况，最好通过使用心跳机制。如果集群检测到故障，它将将故障服务器拥有的LUN重新分配给集群。集群重新分配LUN后，将激活包含故障服务器的IP地址和网络名称的恢复组。随后，集群将承担故障服务器的身份，并为其用户提供服务，直到发生故障的服务器被修复或更换。
