This use of the back-end channel for all storage controller to storage device N-way connectivity as well as controller to controller N-way connectivity eliminates the need for a dedicated inter-controller interface for such N-way connectivity and eliminates the over-utilization of a front-end (e.g., network) communication path for providing N-way connectivity in the storage system.

A technique for modifying an input/output (I/O) connection type between a client and a server includes determining, by the client, when at least partial storage access control for the client is to be migrated from a first virtualized I/O server to a second virtualized I/O server. An I/O connection type, from among multiple available I/O connection types available between the client and the second virtualized I/O server, is then selected by the client when the at least partial storage access control for the client is to be migrated. The selected I/O connection type is then communicated, by the client, to the second virtualized I/O server, which is configured to facilitate storage access for the client using the selected I/O connection type.

A method and tangible medium embodying code for allocating resource units of an allocatable resource among a plurality of clients in a computer is described. In the method, resource units are initially distributed among the clients by assigning to each of the clients a nominal share of the allocatable resource. For each client, a current allocation of resource units is determined. A metric is evaluated for each client, the metric being a function both of the nominal share and a usage-based factor, the usage-based factor being a function of a measure of resource units that the client is actively using and a measure of resource units that the client is not actively using. A resource unit can be reclaimed from a client when the metric for that client meets a predetermined criterion.

The management computer calculates an excess storage capacity based on a pool usage status for the pool. The management computer specifies a pool application for the pool and the condition for the pool application based on the pool application information and the application condition information. The management computer judges whether the specified condition is satisfied even in the case in which a storage area having a storage capacity equivalent to or less than the calculated excess storage capacity is deleted from the pool. In the case in which the result of the judgment is positive, the management computer defines a capacity equivalent to or less than the excess storage capacity as an unused capacity.

A method for deleting a relation between a source and a target in a multi-target architecture is described. The multi-target architecture includes a source and multiple space-efficient (SE) targets mapped thereto. In one embodiment, such a method includes initially identifying a relation for deletion from the multi-target architecture. A space-efficient (SE) target associated with the relation is then identified. A mapping structure maps data in logical tracks of the SE target to physical tracks of a repository. The method then identifies a sibling SE target that inherits data from the SE target. Once the SE target and the sibling SE target are identified, the method modifies the mapping structure to map the data in the physical tracks of the repository to the logical tracks of the sibling SE target. The relation is then deleted between the source and the SE target.

Methods and apparatus are disclosed for virtualizable, forward-compatible hardware-software interfaces. Embodiments may be used in a driver whether it is a physical driver or a virtual driver. Commands are queued from the driver and fetched to the device. An actions table is accessed to determine if drivers are permitted to perform commands. Events are queued for the drivers responsive to commands. If drivers are not permitted to perform a command, device firmware may forward the command to a privileged driver to perform the required command. If a driver is only permitted to perform a command with assistance the command is forwarded for corrections and execution. If a command is to be dropped, a completion event may be queued as if the command had executed. Drivers may have no indication of which actions were taken. The actions table may be changed for hardware/software modifications or dynamically according to configuration changes.

Disclosed herein are systems, methods, and non-transitory computer-readable storage media for efficiently storing information. For example, lower-quality copies of files can be stored locally, and higher-quality, original versions of files can be stored on the Internet. Storing a lower-quality or lower-resolution version of a file locally can reduce local storage requirements. The higher-quality, or higher resolution, original version of a file can be retrieved from the cloud if the locally stored version is not of sufficient quality for a particular use. However, the lower-quality copy may be of sufficient quality for most usages.

For forming an initial bitmap from deduplicated data on virtual volumes, discrete blocks are sorted according to frequency of occurrence to form a revised bitmap to first include a plurality of most common discrete blocks. A physical volume map is created from the revised bitmap. An initial virtual volume of the virtual volumes contained on a corresponding original physical volume is reviewed to determine whether moving the initial virtual volume to a different physical volume reduces the total number of data blocks in the physical volume map. The initial virtual volume is deleted from its corresponding original physical volume and added to the different original physical volume to create a revised physical volume map including revised physical volumes. The revised physical volume is written to the target set of physical media using the revised physical volume map.

A technique for transferring data in a digital signal processing system is described. In one example, the digital signal processing system comprises a number of fixed function accelerators, each connected to a memory access controller and each configured to read data from a memory device, perform one or more operations on the data, and write data to the memory device. To avoid hardwiring the fixed function accelerators together, and to provide a configurable digital signal processing system, a multi-threaded processor controls the transfer of data between the fixed function accelerators and the memory. Each processor thread is allocated to a memory access channel, and the threads are configured to detect an occurrence of an event and, responsive to this, control the memory access controller to enable a selected fixed function accelerator to read data from or write data to the memory device via its memory access channel.

Still further, the encoded data can be generated by any of multiple different erasure coding algorithms, where again storage of the encoded data is not restricted to a single group of drives based on the erasure algorithm being utilized to encode the data. In another embodiment, the encoded data can be “stacked” (aligned) on select drives to reduce the number of head seeks required to access the data.

The preliminary number of clusters is generated based on shortest distances between the sets of data objects, each cluster comprising one or more sets of data objects and each set of data objects comprising one or more chunks of data. A chosen cluster is identified from a set of clusters by identifying a cluster having a greatest number of common chunks within as few sets of data objects. Responsive to an export-size of the chosen cluster failing to exceed the available storage capacity of the removable storage system, the chosen cluster is exported to the removable storage system.
