Abstract: Technologies are described herein for implementing a space-efficient internal energy storage apparatus in a data storage device or other electronic device have a metallic or otherwise electrically-conductive housing or case structure. The energy storage apparatus comprises an interior surface of the metallic housing, a conductive layer disposed parallel to the interior surface of the metallic housing, and a separator disposed between the interior surface and the conductive layer. The metallic housing is configured to act as a first electrode of the energy storage apparatus and the conductive layer is configured to act as an opposing electrode to the first electrode.

Abstract: Method and apparatus for managing data in a data storage device configured as a storage compute appliance. In some embodiments, the data storage device has a controller circuit and a non-volatile memory (NVM) with an overall data storage capacity. A processor authenticates each of a plurality of authorized users of the NVM via data exchanges between a host device and the processor without reference to an external authentication authority device. Upon authentication, each authorized user is allocated a separate portion of the overall data storage capacity of the NVM using an allocation model. The size of at least one of the separate portions is subsequently adjusted based on an access history of the NVM. The storage device may be a key-value storage device so that a separate set of key values is provided to each authorized user to identify data blocks stored to and retrieved from the NVM.

Abstract: A memory controller manages memory access operations through a flash memory interface of a memory array of a solid-state storage device connected to a host. The memory controller executes a first memory access operation in the memory array. The first memory access operation has a first priority. The memory controller detects a suspending memory access operation available for execution in the memory array and having a higher priority than the first priority. The detection operation distinguishes between suspending memory access operations and non-suspending memory access operations. The memory controller suspends execution of the first memory access operation in the memory array and executes one or more memory access operations having higher priorities than the first priority and being available for execution in the memory array. The memory controller resumes the execution of the first memory access operation in the memory array.

Abstract: Method and apparatus for managing data in a data storage device configured as a storage compute appliance. In some embodiments, the data storage device has a non-volatile memory (NVM) and a controller circuit. The NVM stores a plurality of data sets encrypted by at least one encryption key. The controller circuit performs a storage compute appliance process by locally decrypting the plurality of data sets in a local memory of the data storage device, generating summary results data from the decrypted data sets, and transferring the summary results data across the host interface to an authorized user without a corresponding transfer of any portion of the decrypted data sets across the host interface.

Abstract: Systems and methods presented herein provide for data storage for a plurality of host systems. In one embodiment, a storage system comprises a storage unit, and a controller. The controller is operable to process a write I/O request from a first of the host systems, to determine an identity of the first host system from the write I/O request, to encrypt data of the write I/O request based on the identity of the first host system, to locate a storage space allocated to the first host system in the storage unit, to determine that a size of the data of the write I/O request requires more storage space than currently allocated to the first host system, to increase the storage space allocated to the first host system by the size of the data of the write I/O request, and to write the encrypted data to the storage unit.
