Example redundant array of independent disks (RAID) storage systems and methods provide rebuild of logical data groups. Storage devices are configured as a storage array for storing logical data groups distributed among the storage devices. The logical data groups are written in a configuration of RAID stripes in the storage devices. A failed storage device may be rebuilt using the RAID stripes and completed rebuilds of logical blocks may be tracked during the device rebuild process. A logical group rebuild status may be determined by comparing the completed rebuilds of logical blocks to a logical group map. The logical group rebuild status for each logical data group may be provided as complete in response to all logical blocks in the logical data group having been rebuilt. In the event the array rebuild fails, the logical groups that did complete rebuild may be brought online as a partially completed rebuild to prevent the loss of the entire array.

Methods and systems may provide for detecting a manual addition of first content to an interactive display and defining a content boundary around the first content. Additionally, a first automatic rescaling of the first content within the content boundary may be conducted in response to one or more of a manual modification of the first content or a trigger related to a characteristic of the first content. In one example, a manual reposition request is detected with respect to the first content, the first content is moved to a new position on the interactive display based on the reposition request, and a second automatic rescaling of the first content is conducted based on a state of second content that is adjacent to the new position.

Scaling content on touch-based systems

Example tiered storage systems, storage devices, and methods provide tier configuration by peer storage devices. Each tiered storage device is configured to communicate with a plurality of peer storage devices with storage device identifiers. The storage devices may query each other for performance characteristics and/or self-assigned performance tiers and organize the storage devices into a tier configuration. Each storage device, a storage controller, another system, and/or some combination may store metadata that describes the tier configuration. The tier configuration may then be used to route host data commands among the plurality of peer storage devices.

Embodiments of the present invention disclose a method, computer program product, and system for utilizing a block storage device as Dynamic Random-Access Memory (DRAM) space, wherein a computer includes at least one DRAM module and at least one block storage device interfaced to the computer using a double data rate (DDR) interface. During boot up, the computer configures DRAM and block storage devices of the computer for utilization as DRAM or block storage. Then the computer determines that more DRAM space is required. Responsive to determining that more DRAM space is required, the computer transforms a block storage device into DRAM space. Once the computer determines that the transformed block storage device that is being used for DRAM space is no longer needed to be used as DRAM space, the computer transforms the block storage device back to block storage space.

Flexible utilization of block storage in a computing system

Example peer storage systems, storage devices, and methods provide peer data recovery across a peer communication channel. Peer storage devices establish peer communication channels that communicate data among the peer storage devices. A storage device may identify storage media segments from their storage medium for recovery of failed data units. A peer storage device may be identified that contains recovery data for the failed data units. The recovery data may be received over the peer communication channel and the storage media segments may be recovered using the recovery data.

Storage systems with peer data recovery

Example storage systems, storage devices, and methods provide secure transfer of data between peer storage devices using protection information. Data operation commands may be received that use a protection information data block format for transferring a target data block between peer storage devices. A local data operation may operate on the target data block in a first storage device and compare at least one protection information tag value to a first data check value. At least one destination verification protection information tag value and the target data block may be transferred to a second storage device through a peer communication channel. The destination verification protection information tag value may be compared to a destination data block protection information tag value by the second storage device. The second storage device may then execute a data operation on the target data block. Protection information tag values may include guard tag values, reference tag values, and application tag values managed by the peer storage devices.

Example redundant array of independent disks (RAID) storage systems and methods provide rebuild of logical data groups in priority order. Storage devices are configured as a storage array for storing logical data groups distributed among the storage devices. The logical data groups are written in a configuration of RAID stripes in the storage devices. A logical group index includes a logical group map for each logical data group and identifies corresponding logical blocks. When a storage device fails, the rebuild queue is ordered based on the priority of the logical data groups and rebuild to the replacement storage device is completed in the priority order.

Example peer storage systems, storage devices, and methods provide peer operation state indicators for managing peer-to-peer operations. Peer storage devices establish peer communication channels that communicate data among the peer storage devices that bypasses the storage control plane for managing the peer storage devices. The peer storage devices identify peer operations that communicate data through the peer communication channels and generate a peer operation state during the operating period of the peer operations. The peer storage devices activate a state indicator configured to indicate the peer operation state. The state indicator may be used to prevent a storage controller or other entity with access to the storage device, including administrative personnel, from performing an operation that may corrupt data or truncate a media operation involving peer-to-peer communications.

Embodiments include method, systems and computer program products for aligning visual content to search term queries. In some embodiments, one or more search terms may be received. A plurality of results may be obtained using the one or more search terms on metadata associated with preprocessed visual media. A subset of frames may be selected for each of the plurality of results. A search results set may be generated by optimizing the subset of frames for each of the plurality of results. The search results set may be transmitted.

Aligning visual content to search term queries

When rebuilding a RAID (Redundant Array of Independent Disks) array in which a drive has failed, if another RAID array contains a mirror copy of the of the rebuilding RAID array content, this mirroring RAID array can be used to more rapidly rebuild the RAID array with the failed drive. Data requests to the rebuilding RAID array can be redirected to the mirroring RAID array; data can be transferred from the mirroring RAID array; or a combination of these can be used to finish rebuilding more quickly. When transferring data to the rebuilding array from the mirroring array, the transfer can be performed as a direct memory access (DMA) process independently of the RAID module of either array.

RAID array rebuild assist from external array copy

Example peer storage systems, storage devices, and methods provide data scrub using a peer communication channel. Peer storage devices establish peer communication channels that communicate data among the peer storage devices. A storage device may identify data segments from their storage medium for a data scrub process. A peer storage device may be identified that contains corresponding data segments to the data segment being scrubbed. A corresponding lock command may be sent over the peer communication channel to lock the corresponding data segments during the data scrub process. A data scrub error report may be generated from the data scrub process. If an error is discovered during the data scrub process the storage device may use the peer communication channel to retrieve recovery data from peer storage devices to rebuild the data segment with the error.

Storage systems with peer data scrub

Example tiered storage systems, storage devices, and methods provide tier configuration for routing of data commands by peer storage devices. Each tiered storage device is configured to communicate with a plurality of peer storage devices with storage device identifiers. Each storage device is assigned to a performance tier in a tier configuration that determines which host data tier should be stored in the storage media of the storage device, the local performance tier for the storage device. If the local performance tier of the storage device does not match the host data tier for a data command or stored data element when the storage device determines the host data tier, the storage device selectively forwards the host data to another peer storage device with the performance tier that matches the host data tier. The storage device may periodically review the data it contains to evaluate whether stored data elements still match the criteria for the local performance tier and forward data elements that do not to a peer storage device with the appropriate performance tier.
