摘要： The present invention relates to managing I/O requests in a storage system. By dynamically changing the scheduling parameters to achieve optimal turn around time for I/O requests pending for processing at a component in the storage system. The scheduling parameters are changed based on a feedback mechanism. The turn around time of the I/O request are calculated as the ratio of I/O request processing rate and the average number of I/O requests in the component.

摘要： Dynamic discovery of active peer applications and information related thereof in a network is described. In one embodiment of the present invention, the discovery and information related to peer applications is maintained by a plurality of network device peers. This information is supplemented by device or peer application failure information, which is identified through point-to-point communication initiated by a failure to receive a multicast packet from a particular network peer application.

摘要： Systems and methods for path selection for application commands are described. To this end, information associated with at least one application command that were processed at least one port of a target device is received. For a subsequent application command, a set of ports of the target device is determined. In one implementation, the set of ports is determined based on information associated with the subsequent application command. Once the set of ports is determined, the subsequent application command is directed to a port selected from the set of ports.

摘要： A high availability DAS system uses a solid state cache to provide near active-active performance in a DAS duster, while retaining the implementation simplicity of active-passive or dual active system. Each node in the duster may include a solid state cache that stores hot I/O in an active-active mode, which allows the data to be read from or written to the underlying dual-active or active/passive DAS RAID system only when access to the “hot Region” cools down or in the case of Cache Miss. The hot I/O data includes hot read data that accumulated dynamically regardless of ownership of the drives where the hot read data is permanently stored. The hot I/O data also includes hot write data that is mirrored across the solid state cache memories to avoid potential dirty write data conflicts and also to provide High Availability in case of server failures.
