摘要： Storage requests are divided into high-priority requests generally requiring low response time and low-priority requests generally requiring high throughput. The high-priority requests are further divided into several priorities reflecting different classes of service. The low-priority requests are placed on a low-priority request queue where they are executed in a throughput-optimizing order generally different from their arrival order. For each high-priority request, if there are not more than a predetermined number n (e.g., 1) outstanding requests for execution by the disk drive of greater priority, then the request is placed on a high-priority request queue where it is generally executed ahead of requests on the low-priority request queue. If there are more than n such greater-priority requests outstanding, then the high-priority request is placed on the low priority request queue and included in the throughput optimization along with the low-priority requests. The number of priority levels for the high priority requests may be two or more, and in one illustrated embodiment is equal to three.

摘要： This invention is a system and method for preparing workload data that may be accessed in a data storage environment and then replayed for testing or other reasons. The invention has the capability to prepare a trace of I/Os to a data storage system for an extended period of time for replaying these I/Os back to that or another system. Variables may also be manipulated through a preparation process and is particularly useful for customizing benchmarking tests, or consolidation, or trouble-shooting, or capacity planning.

摘要： Described is storage system and method for reducing power consumption. The storage system has first and second physical disks configured to provide mirroring. The first physical disk is placed into a power-saving mode of operation, while the second physical disk is in an active mode of operation responding to read and write requests. The first physical disk transitions from the power-saving mode of operation to an active mode of operation for destaging writes pending from cache to the first physical disk, while the second physical disk responds to read and write requests. The second physical disk transitions from the active mode of operation to the power-saving mode of operation, while the first physical disk responds to read and write requests.

摘要： A mixed queue method for managing storage requests directed includes a low-priority request queue on which all low-priority requests are placed and where they are subject to throughput optimization by re-ordering. When a high-priority request limit has not been reached, high-priority requests are placed on a high-priority request queue where they are executed in a pre-emptive manner with respect to the queued low-priority requests, thus experiencing reduced access time. When the high-priority request limit has been reached, the high-priority requests are placed on the low-priority request queue, such that the high-priority requests are included in the throughput optimization along with the low-priority requests on the request queue. Starvation of the low-priority requests is avoided, and the overall throughput of the disk drive is maintained at a relatively high level. The high-priority request limit can be realized in several ways, such as by monitoring the number of outstanding high-priority requests or the rate at which high-priority requests are issued to the disk drive.
