Abstract: A method, non-transitory computer readable medium, and device that assists with managing storage in a distributed deduplication system includes receiving an object to be stored from a client computing device. The received object is divided into a plurality of fragments. A plaintext hash value and a ciphertext hash value is determined for each of the plurality of fragments, wherein each of the plurality of fragments is renamed with the corresponding determined ciphertext hash value. Each of the renamed plurality of fragments are stored in a plurality of storage repositories.

Abstract: The disclosed technology relates to verifying and validating a received executable function to be executed on a function as a service platform (FaaS), by applying one or more verification and validation techniques prior to runtime. The verified and validated executable function is temporarily stored. The temporarily stored verified and validated executable function is executed on the FaaS platform at the runtime.

Abstract: Methods, non-transitory machine readable media, and computing devices that accelerate storage operations are disclosed. With this technology, computational storage devices are assigned by a NIC processor of a computational network interface controller (NIC) to storage locations corresponding to respective partitions of an n-dimensional space. One of the storage locations to which a data location in the n-dimensional space maps is then identified by the NIC processor. The data location is determined based on a hash for data associated with a received storage operation. The NIC processor subsequently communicates via a system bus with a storage processor of one of the computational storage device to service the storage operation. The storage processor is coupled directly to flash media of the one of the computational storage device that is assigned to the one of the storage locations and maintains a key/value store comprising the data.

Abstract: A system can apply file placement rules to dynamically place files and directories within file system views backed by objects in an object storage system. After detection of an update to a first file system view that causes an update of an object in a storage grid, an object manager begins evaluation of file placement rules against metadata of the object. For each file placement rule that is triggered, the object manager determines identifies gateways that export the first file system view. The object manager then instructs the gateways to update their representations of the first file system view. The disclosed embodiments may be able to scale to managing hundreds of billions of files spanning thousands of file system views, especially in the presence of disconnected operation.

Abstract: A storage system includes data storage devices, bus conductors, and mobile reader/writer devices. Each of the storage devices is positioned between insulators, is at one of a plurality of locations on one of one or more shelf assemblies, and comprises a processor coupled to a memory and an interface device. One of the bus conductors is adjacent each of the insulators. Each of the reader/writer devices includes a transport apparatus, a processor and a memory. The transport apparatus is configured to move one of the reader/writer devices to one or more of the locations when engaged. The processor is coupled to the transport apparatus and the memory and is configured to execute machine executable code to: engage the transport apparatus to position one of the reader/writer devices to one of the locations in response to a received operation; couple power to one of the storage devices; and execute the operation.

Abstract: Technology is disclosed for a data storage architecture for providing enhanced storage resiliency for a data object. The data storage architecture can be implemented in a single-tier configuration and/or a multi-tier configuration. In the single-tier configuration, a data object is encoded, e.g., based on an erasure coding method, to generate many data fragments, which are stored across many storage devices. In the multi-tier configuration, a data object is encoded, e.g., based on an erasure coding method, to generate many data segments, which are sent to one or more tiers of storage nodes. Each of the storage nodes further encodes the data segment to generate many data fragments representing the data segment, which are stored across many storage devices associated with the storage node. The I/O operations for rebuilding the data in case of device failures is spread across many storage devices, which minimizes the wear of a given storage device.

Abstract: In at least one embodiment, a method of operating a multiple-data-storage-devices enclosure is disclosed. The method includes: receiving a first read request from a first requester device for a first requested data fragment; identifying a first target data storage device storing the first requested data fragment based at least partly on the first read request; activating, independently of receiving the first read request, only a subset of data storage devices in the enclosure, wherein the subset includes the first target data storage device; retrieving, based at least partly on the first read request and in response to activating the subset, the first requested data fragment from the first target data storage device; and transmitting the first requested data fragment to the first requester device.

Abstract: A service level objective (SLO) subsystem that includes an SLO engine in a network storage system that allows new degrees of freedom to be added to the SLO subsystem, without requiring any modification of an associated SLO engine or the system's existing SLOs, and without requiring the SLO engine to have any a priori knowledge of the new degrees of freedom. In certain embodiments, the system has a modular design which includes the SLO engine and one or more SLO modules that interface with the SLO engine. Each SLO module corresponds to a different degree of freedom. Each SLO module evaluates SLO compliance and determines what specific action(s) within its corresponding degree of freedom should be taken to comply with an SLO.
