摘要： A primary active manager can manage a first copy of a database in a first computer system cluster according to a set of management rules that provide for an active copy and one or more passive copies of the database at a given time. The primary active manager can also manage a second copy of the database in a second computer system cluster according to the rules. The rules can allow the first copy of the database or the second copy of the database to be the active copy if one or more criterion in the rules is met for that active copy. The first copy can be designated as the active copy and the second copy can be designated as a passive copy. A failure of the first copy can be detected, and in response, the second copy can be automatically designated as the active copy.

摘要： A method which includes receiving a request to perform encapsulating security payload (ESP) processing for data exchanged between a node and an other node over a secure network connection established via an Internet Protocol security (IPsec) security association. Information associated with the IPsec security association is obtained based on the request. The information indicates a prepend data unit size for an initialization vector, a generated data unit size for the initialization vector and an append data unit size for the initialization vector. A composition of each initialization vector included with encrypted data exchanged between the node and the other node based, at least in part, on the prepend, generated and append data unit size for the initialization vector is then determined.

摘要： In one embodiment, the present disclosure provides a method capable of processing a variety of different operations. A method according to one embodiment may include loading configuration data from a shared memory unit into a hardware configuration register, the hardware configuration register located within circuitry included within a hardware accelerator unit. The method may also include issuing a command set from a microengine to the hardware accelerator unit having the circuitry. The method may additionally include receiving the command set at the circuitry from the microengine, the command set configured to allow for the processing of a variety of different operations. The method may further include processing an appropriate operation based upon the configuration data loaded into the hardware configuration register. Of course, many alternatives, variations and modifications are possible without departing from this embodiment.

摘要： High availability architecture that employs a mid-tier proxy server to route client communications to active data store instances in response to failover and switchover. The proxy server includes an active manager client that interfaces to an active manager in each of the backend servers. State information and configuration information are maintained separately and according to semantics consistent with needs of corresponding data, the configuration information changing less frequently and more available, the state information changing more frequently and less available. The active manager indicates to the proxy server which of the data storage instances is the currently the active instance. In the event that the currently active instance is inactive, the proxy server selects a different backend server that currently hosts the active data store instance. Client communications are then routed to the different backend server with minimal or no interruption to the client.

摘要： A computer cluster can be divided into a plurality of failure scopes and a voting constraint can be enforced. The voting constraint can allow a portion of the cluster to provide the service if a majority of health votes from cluster members is obtained by that portion. A loss of connectivity between a first failure scope, which has a majority of cluster members in the cluster, and one or more other failure scopes in the cluster can be detected. The loss of connectivity can be such that the first failure scope does not have connectivity to a member in any other failure scope in the cluster. In response to detecting the loss of connectivity, a split brain situation in the cluster can be automatically protected against by preventing the first failure scope from providing the service.

摘要： The present disclosure provides a method for generating RAID syndromes. In one embodiment the method may include loading a first data byte of a first disk block and a first data byte of a second disk block from a storage device to an arithmetic logic unit. The method may further include XORing the first data byte of the first disk block and the first data byte of the second disk block to generate a first result and storing the first result in a results buffer. The method may also include iteratively repeating, loading intermediate data bytes corresponding to the first disk block and intermediate data bytes corresponding to the second disk block from the storage device to the arithmetic logic unit. The method may additionally include XORing the intermediate data bytes corresponding to the first disk block and the intermediate data bytes corresponding to the second disk block to generate intermediate results and generating a RAID syndrome based on, at least in part, the intermediate results. Of course, many alternatives, variations and modifications are possible without departing from this embodiment.
