摘要： System, method and computer program for maintaining cache coherency amongst a plurality of caching storage controllers operating in unison supplying data in response to requests from one or more host computers. The method comprises the steps of defining a reservation data structure to maintain reserved, partial, and full ownership status of data extents that are part of the logical unit or storage volume, and using the reservation data structure to verify that a new update to the data is allowed.

摘要： The present invention is a method for implementing a storage system. The storage system may include a disk array having a disk drive pair which includes a solid-state disk drive and a hard disk drive. The method may include the step of copying a data subset of a data set from the hard disk drive to a spare solid-state disk drive during a solid-state disk drive rebuild process. The data subset includes a first amount of data and the data set includes a second amount of data, where the first amount of data is less than the second amount of data. The method may further include the step of receiving a read request from a host server requesting the data subset. The method further includes the step of directing the read command to the spare solid-state disk drive.

摘要： A system and method for communication amongst a device and multiple controllers. A controller may use a direct communication path to the device or may route the communication to another controller that has a faster communication path to the device. Such a system and method is particularly useful when the device takes a long time to switch from a communication path with the second controller to a communication path with the first controller.

摘要： A system and method for indicating the service status of serviceable elements of a subassembly stores the service status in a memory using a host controller. When the subassembly is removed from the host controller, the memory may be accessed using a second circuit and separate power supply, and indicators may be illuminated to indicate the service status of the elements.

摘要： A tiered data storage system having a cache employs a tiering management subsystem to analyze data access patterns over time, and a cache management subsystem to monitor individual input/output operations and replicate data in the cache. The tiering management subsystem determines a distribution of data between tiers and determines what data should be cached while the cache management subsystem moves data into the cache. The tiered data storage system may analyze individual input/output operations to determine if data should be consolidated from multiple regions in one or more data storage tiers into a single region.

摘要： A storage system is configured to determine a redundancy group configuration for a plurality of storage drives by grouping storage drives with a similar performance group designation together. When a storage drive is inserted, the storage system tests the performance of the storage drive. The storage drive may comprise a serial ATA (advanced technology attachment) (SATA) hard drive and/or a solid state drive. The storage system stores the result in a database. The storage system assigns the storage drive a performance group designation based on the result and groups the storage drive into a redundancy group. The storage system then displays the redundancy group configuration for the plurality of storage drives so that a storage administrator may configure the redundancy groupings of the storage drives of the storage system based on the redundancy group configuration displayed.

摘要： A system may include multi-tenant electronic storage for hosting a plurality of applications having heterogeneous Input/Output (I/O) characteristics, relative importance levels, and Service-Level Objectives (SLOs). The system may also include a management interface for managing the multi-tenant electronic storage, where the management interface is configured to receive a storage resource arbitration policy based on at least one of a workload type, an SLO, or a priority for an application. The system may further include control programming configured to receive an association of a particular I/O stream with a particular application generating the I/O stream, where the association of the I/O stream with the application was determined by analyzing at least one I/O characteristic of the I/O stream, and determine at least one of a cache size or a caching policy for the application based on the association of the I/O stream with the application and the storage resource arbitration policy.
