    Abstract: 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.

    Abstract: 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.

    Abstract: A method for providing online raid migration without non-volatile memory employs reconstruction of the RAID drives. In this manner, the method of the present invention protects online migration of data from power failure with little or no performance loss so that data can be recovered if power fails while migration is in progress, and migration may be resumed without the use of non-volatile memory.

    Abstract: 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.
