Abstract: Systems and methods for tier management in memory-tiering environments. In some embodiments, a method includes accessing, by a first process, a first page of the first process in a first tier of a non-uniform memory access memory; and locking, by a first thread, the first page against demotion. The first thread may be a tier-management thread of the first process, and the locking of the first page may be based on a service level of the first process.

Abstract: A storage device, and a method for operating a storage device. In some embodiments, the storage device includes storage media, and the method includes: determining, by the storage device, that the storage device is in a first fault state from which recovery is possible by power cycling the storage device or by formatting the storage media; determining, by the storage device, that the storage device is in a second fault state from which partial recovery is possible by operating the storage device with reduced performance, with reduced capacity, or in a read-only mode; and operating the storage device with reduced performance, with reduced capacity, or in the read-only mode.

Abstract: A method may include receiving, at a computational device, a command, accessing, based on the command, using a programming interface, a kernel of an operating system operating on a computational circuit of the computational device, and performing, by the operating system, an operation based on the accessing. The accessing may include writing to one or more buckets using the programming interface. The one or more buckets may include one or more files. The accessing may include reading from one or more buckets using the programming interface. The method may further include performing, based on the accessing, a function call using the kernel. The receiving the command may include receiving, by a protocol, the command. The protocol may include a storage protocol. The storage protocol may include Nonvolatile Memory Express (NVMe). The receiving the command may include receiving, by command logic at the computational device, the command.

Abstract: A method includes receiving, at a controller of a computational storage (CS) device, a request to allocate computational storage to an application of a host device. The request includes a resource set ID associated with the application. The method further includes identifying a memory range within a memory region of the CS device. The method further includes storing, in a data structure associated with the resource set ID, an association between a memory range identifier (ID) of the memory range, the memory region, and an offset within the memory region. The method further includes sending the memory range ID to the host device.

Abstract: A storage device is disclosed. A first storage media may store data. The first storage media may be of a first storage type, and may be organized into at least two blocks. A second storage media may also store data. The second storage media may be of a second storage type different from the first type, and may also be organized into at least two blocks. A controller may manage reading data from and writing data to the first storage media and the second storage media. Metadata storage may store device-based log data for errors in the storage device. The drive-based log data for errors may include a unified log data for the first storage media and the second storage media. An identification circuit may identify a suspect block in the at least two blocks in the first storage media and the second storage media, responsive to the unified log data. Parameters for the first storage media and the second storage media may be derived from a unified parameter in the unified log data in proportion to the number of write operations and the number of read operations to each storage media, relative to the number of write operations and the number of read operations of the storage device.
