Abstract: A computing device includes processing units and a shared processor cache. Each cache line is associated with a different plurality of accounting bits, including a unit bit associated with each processing unit. An operation by a particular processing unit on a particular cache line is identified. If the operation is a read consumed by that processing unit, and when a unit bit for that processing unit in the accounting bits associated with the particular cache line is not set, at least the value portion of the particular cache line is stored or referenced in the trace, and the particular unit bit is set. If the operation is a write, each unit bit in the accounting bits associated with the cache line that are associated with any processing unit other than the particular processing unit is cleared, and the particular unit bit associated with the particular processing unit is set.

An example method comprises receiving a plurality of bytes and determining a particular endianness format of the plurality of bytes. The method can include, responsive to determining the particular endianness format is a first endianness format, reordering bits of each byte of the plurality of bytes on a bytewise basis, storing the reordered plurality of bytes in an array of memory cells, and adjusting a shift direction associated with performing a number of operations on the plurality of bytes stored in the array. The method can include, responsive to determining the particular endianness format is a second endianness format, storing the plurality of bytes in the array without reordering bits of the plurality of bytes.

Abstract: A remote agent for providing backup services to applications includes a persistent storage and a backup manager. The persistent storage stores backup policies for the applications. The backup manager identifies an application of the applications for providing the backup services; generates an application backup template based on a backup policy of the backup policies for the application; sends the generated application backup template to a production host that hosts the application; and makes a determination that the backup policy has been triggered. In response to the determination, the backup manager initiates a native data extraction from the application using the application backup template to obtain a native data dump; stores the native data dump in backup storage; and indexes the stored native data dump as a backup.

Abstract: A memory controller includes: an interface configured to operably communicate with a host device; a temperature detecting circuit configured to operably detect an ambient temperature, wherein when the ambient temperature is beyond a predetermined temperature range, the temperature detecting circuit generates a control signal; and a processing circuit coupled to the interface and the temperature detecting circuit, for selecting one of a plurality of data program schemes to program data into a first storage block of a flash memory according to the control signal.

Abstract: In a half-compressed RAID 1 system a first copy of a data set is maintained in an uncompressed state and a second copy of the data set is maintained in a compressed state, where corresponding compressed and uncompressed blocks are stored on different physical devices. The result is RAID 1 reliability with storage space consumption similar to RAID 5-3+1. Compression striping in which the compressed and uncompressed data is distributed across two or more storage devices can be used to reduce data access response time. Further, delayed compression can be used to reduce the time required to perform WRITE ops. Compression may also be performed based on resource availability or storage tier hierarchy.

Abstract: The present disclosure includes apparatuses and methods related to shifting data. An example apparatus comprises a cache coupled to an array of memory cells and a controller. The controller is configured to perform a first operation beginning at a first address to transfer data from the array of memory cells to the cache, and perform a second operation concurrently with the first operation, the second operation beginning at a second address.

Abstract: A space allocator in a file management system maintains and uses one or more offsets and a stored value of the largest space skipped on previous scans to increase the efficiency of scans for available space in a file system space map. When the space allocator determines a current allocation request is greater than the largest space skipped in the previous scan, a last allocated offset can be used to begin scanning to reduce the portion of the map to scan in order to find available space. When the space allocator determines the current allocation request is less than or equal to the largest space skipped in the previous scan, a first available offset can be used to begin scanning for an appropriate unused space.

Some implementations of the system may include a storage media, and a storage controller executable by a processor that may include an interface processor, a controller logic, and a media processor configured to communicate with an application and the storage media to perform aspects of the method.

Abstract: A processor can determine that a set of the memory cells is controlled by signals from a first portal. The processor can determine a function of a second portal in a relationship between the first portal and the second portal. The processor can cause, in response to a determination that the function of the second portal is a specific function, a memory control circuitry to be configured so that a subset, of the set, is controlled also by signals from the second portal. The processor can determine a function of a third portal in a relationship between the first portal and the third portal. The processor can cause, in response to a determination that the function of the third portal is the specific function, the memory control circuitry to be configured so that the subset, of the set, is controlled also by signals from the third portal.

Abstract: An apparatus is configured to generate a current snapshot set for a consistency group comprising a plurality of storage volumes subject to replication from a source storage system to a target storage system, and to schedule a differential scan of the current snapshot set relative to a previous snapshot set generated for the consistency group. For each of one or more snapshot trees maintained for the consistency group, a determination is made as to whether or not a first node corresponding to the previous snapshot set is an ancestor of a second node corresponding to the current snapshot set, and a manner in which an instance of the differential scan is performed for the snapshot tree is altered responsive to a result of the determination.

The persistent storage stores data associated with a portion of the virtual machines. The backup storage client provides access to second data associated with a second portion of the virtual machines stored in a backup storage. The production agent identifies an instant access request for a virtual machine and, in response to identifying the instant access request, generates instant access virtual machine data in the backup storage using a portion of the second data associated with the virtual machine; locally mounts the generated instant access virtual machine data; locally instantiates the virtual machine using the instant access virtual machine data; and executes the instantiated virtual machine using the instant access virtual machine data.

Abstract: In some examples, a system dynamically adjusts a proportion of incoming data blocks for which respective fingerprints are added to a fingerprint index, where the fingerprint index correlates fingerprints for data blocks to storage location indicators for the data blocks. The system inputs, into a buffer, fingerprint index delta updates for the incoming data blocks according to the dynamically adjusted proportion, and updates the fingerprint index based on the fingerprint index delta updates input into the buffer. The system retrieves, in response to a fingerprint of an incoming data block, a collection of block entries from a block location index that stores information for data blocks in temporal order, and deduplicates the incoming data blocks using the collection of block entries from the block location index.

Abstract: Example apparatus and methods control a data storage system to store data in a self-describing logical data storage capsule using a logical cylindrical recording format. Example apparatus and methods assign a searchable, globally unique identifier to the capsule and associate the globally unique identifier with a user. The logical data storage capsule is migrated from a first data storage medium to a second data storage medium without translating or reformatting the data storage capsule. The data storage capsule contains information describing to a data storage device how to migrate the capsule without translating or reformatting the data storage capsule. Example apparatus and methods dynamically select an error correction approach for storing data in the data storage capsule, de-duplicate, and encrypt the data storage capsule. The data storage capsule may be local, or may be part of a cloud-based storage system.

Abstract: A protection module for an electronic circuit prevents unintended write operations by a master module to functional registers of a protected module. The protection module includes soft lock bits (SLBs) that indicate whether corresponding functional registers are locked and control logic that supports (i) a page select (PS) control parameter that indicates whether access by the master module is to the functional registers or the SLBs and (ii) a mode select (MS) control parameter that indicates whether access by the master module to the functional registers is in a normal access mode, in which each written-to functional register is left unlocked, or an auto-lock access mode, in which each just-written-to functional register is automatically locked by setting the corresponding SLB. The functional registers and the SLBs share addresses that can fit within a single address space that includes the control parameters.
