摘要： An apparatus and associated methodology contemplating a data storage system having a group of processor-controlled intelligent storage elements (ISEs). Each ISE in the group individually includes storage resources and a network interface. The storage resources of all the ISEs in the group collectively define a field of storage (FoS). A portion of the FoS is addressable by a remote device or by another ISE via the respective ISE's network interface. An ISE FoS structure (ISEFoS) is individually stored in nonvolatile memory within each of the ISEs in the group. Each ISEFoS contains parametric data pertaining to every ISE in the group. Orchestration logic executed by one of the ISEs of the group (a recipient ISE), in response to the recipient ISE receiving a storage management operation request via the network interface, queries the recipient ISE's ISEFoS in order to optimally determine which ISE in the group to use in executing the storage management operation request.

摘要： Method and apparatus for managing data in a multi-device data storage array. In accordance with various embodiments, a storage array of independent data storage devices are arranged to form a fast pool and a slow pool of said devices. A controller is adapted to migrate a distributed data set stored across a first plurality of said devices in the slow pool to a second plurality of said devices in the fast pool. The migration is carried out responsive to a return on investment (ROI) determination by the controller that an estimated cost of said migration will be outweighed by an overall improved data transfer capacity of the storage array over a predetermined minimum payback period of time. In some embodiments, the fast pool is formed from a plurality of solid-state drives (SSDs) and the slow pool is formed from a plurality of hard disc drives (HDD).

摘要： A method, apparatus and program storage device for providing intelligent rebuild order selection is a storage array is disclosed. The interrelationship of the data on the drives to be rebuilt and the remaining drives in the system is examined. A relative score for a rebuild record to be rebuilt is based upon the manner in which the RAID data is placed on the other drives. The rebuild record with the highest relative risk is identified as the rebuild record to be rebuilt next.

摘要： A method, apparatus and program storage device for dynamically resizing mirrored virtual disks in a RAID storage system is disclosed. Mirrored virtual disks are expanded by creating the amount of storage necessary by providing RAIDs on each subsystem that is associated with each of the components of the mirror set, attaching the RAIDs to the specific Virtual Disks for each of the mirror devices, and specifying the Virtual Disk size and mapping this directly to all components via the source Vdisk of the mirror set. To decrease the size of mirrored virtual disks the process is reversed, with the inclusion of the optional requirement that some raids will need to be truncated to provide exact shrink values without sacrificing storage space.

摘要： A method and system for data storage provides a digital fast-write storage device, a plurality of digital slow-write storage devices, and a controller. The digital fast-write storage device might be a solid state drive. The digital slow-write storage devices might be conventional rotational media drives. Typically, read operations are directed to the fast-write storage device. The slow-write storage devices provide redundancy by mirroring the contents of the high-speed storage device. Data on the slow-write storage devices is organized in stripes, allowing data to be written in parallel. The number of slow-write storage devices can be chosen to compensate for the speed differential on write operations. In some embodiments, the controller will represent the storage system as a virtual disk drive.
