    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： The host interface module is configured to receive a plurality of I/O request which includes an associated priority; create an I/O request queue for each associated priority; define a threshold value for the queue length for each of the plurality of I/O request queues; and determine if the queue length for one of the plurality of the I/O request queue corresponding to the associated priority is less than the defined threshold value for the queue length for the one of the plurality of the I/O request queues. If the queue length of the one of the plurality of I/O request queues is more than the defined threshold value for the queue then the host interface module is further configured to rejecting the I/O request and sending a queue full message; wherein the threshold value for the queue length is based on the processing rate of the I/O requests in the plurality of the I/O request queues.

    摘要： The invention relates to management of a plurality of I/O requests in a storage system. The host interface module is configured to receive a plurality of I/O request which includes an associated priority; create an I/O request queue for each associated priority; define a threshold value for the queue length for each of the plurality of I/O request queues; and determine if the queue length for one of the plurality of the I/O request queue corresponding to the associated priority is less than the defined threshold value for the queue length for the one of the plurality of the I/O request queues. If the queue length of the one of the plurality of I/O request queues is more than the defined threshold value for the queue then the host interface module is further configured to rejecting the I/O request and sending a queue full message; wherein the threshold value for the queue length is based on the processing rate of the I/O requests in the plurality of the I/O request queues.

    摘要： Methods to provide workload performance control are described herein. Performance statistics for a plurality of workloads are obtained for a second time interval, which includes a plurality of first time intervals. The performance statistics is based on monitored data (220) obtained at each of the plurality of first time intervals. From the plurality of workloads, at least one workload having an anomaly in resource allocation is identified using the performance statistics. Resources, to at least mitigate the anomaly are associated with the at least one workload.

    摘要： Under the present invention, a small cache is used for the selective buffering of devices of a heterogeneous striping group (i.e., striping group made of devices with unequal capacities) to match the load on each device to its capacity. The inventive caching algorithm utilizes a device map, or disk map, and applies a cache distribution factor for each device of a group to determined how to selectively buffer blocks read from different devices of a striping group; thereby placing different loads on the different devices of a striping group in accordance with their capacities.

    摘要： A method and system for improving load balancing in a file server is disclosed. The method includes determining the existence of an overload condition on a storage device, the storage device having a plurality of retrieval streams accessing at least one file thereon; selecting a first retrieval stream reading a file; replicating a portion of said file being read by said first retrieval stream onto a second storage device; and reading the replicated portion of said file on said second storage device with a retrieval stream capable of accessing the replicated portion of said file. The method and system enables the dynamic replication of data objects to respond to fluctuating user demand. The method and system is particularly useful in file servers such as multimedia servers delivering continuously in real time large multimedia files such as movies.
