Systems, apparatuses and methods may provide for technology that detects a first failure in a first storage server, wherein the first storage server is connected to a first non-volatile memory (NVM) via a switch, selects a second storage server that is connected to the first NVM via the switch, wherein the first storage server and the second storage server are in a storage cluster, and configures the second storage server to host first data resident on the first NVM, wherein configuring the second storage server to host the first data bypasses a cluster-wide rebalance of the storage cluster.

The embodiments described herein describe technologies for non-volatile memory persistence in a multi-tiered memory system including two or more memory technologies for volatile memory and non-volatile memory.

A memory module may include a first memory module comprising a plurality of first memory devices each having an extra memory region, a second memory module comprising a plurality of second memory devices each having an extra memory region, and a control logic suitable for writing/reading data to/from the first memory devices, wherein the control logic writes/reads target data to be transferred to/from a third memory device having an error among the first memory devices, to/from the extra memory regions of the second memory devices.

A method for execution by a distributed storage network begins by receiving a request to transfer a copy of a set of encoded data slices from at least some associated virtual storage vaults to a destination virtual storage vault and continues by determining whether the destination storage unit supports a source virtual storage vault of the at least some source virtual storage vaults. When the destination storage unit supports the source virtual storage vault the method continues by determining a sub-set of encoded data slices of the set of encoded data slices for transfer and finally, by facilitating sending the sub-set of encoded data slices to the destination storage unit.

The described embodiments set forth techniques for preserving clone relationships between files at a computing device. In particular, the techniques involve identifying clone relationships between files in conjunction with performing operations on the files where it can be beneficial to preserve the clone relationships. The operations can include, for example, preserving clone relationships between files that are being copied from a source storage device (that supports file cloning) to a destination storage device that supports file cloning. Additionally, the operations can include preserving clone relationships when backing up and restoring files between a source storage device (that supports file cloning) and a destination storage device that does not support file cloning. In this manner, the various benefits afforded by the clone relationships between files can be retained even as the files are propagated to destination storage devices that may or may not support file cloning.

The present disclosure provides a method and a system of verifying access by a multi-core interconnect to an L2 cache in order to solve problems of delays and difficulties in locating errors and generating check expectation results. A consistency transmission monitoring circuitry detects, in real time, interactions among a multi-core interconnects system, all single-core processors, an L2 cache and a primary memory, and sends collected transmission information to an L2 cache expectation generator and a check circuitry. The L2 cache expectation generator obtains information from a global memory precise control circuitry according to a multi-core consistency protocol and generates an expected result. The check circuitry is responsible for comparing the expected result with an actual result, thus implementing determination of multi-core interconnect's access accuracy to the L2 cache without delay.

An individual data unit for enhancing the security of a user data record is provided that includes a processor and a memory configured to store data. The individual data unit is associated with a network and the memory is in communication with the processor. The memory has instructions stored thereon which, when read and executed by the processor cause the individual data unit to perform basic operations only. The basic operations include communicating securely with computing devices, computer systems, and a central user data server. Moreover, the basic operations include receiving a user data record, storing the user data record, retrieving the user data record, and transmitting the user data record. The individual data unit can be located in a geographic location associated with the user which can be different than the geographic locations of the computer systems and the central user data server.

The disclosed embodiments relate generally to efficient data encoding and transmission. An encoding system determines an encoding interval at which to encode different groups of related data in a data structure. The encoding interval for each group encoded together optimizes the amount of newly received information that is encoded and transmitted in a continuous, repeating loop.

In some examples, a power adapter for sharing redundant power comprises a primary power input; a redundant power input; a redundant power supply identification signal (RPS ID) input; and a controller coupled to the RPS ID input. The controller is to direct power from the primary power input to an electronic device; direct power from the redundant power input to the electronic device, to another power adapter, or both; modify an RPS ID from the RPS ID input in response to directing power from the redundant power input to the electronic device; and output the modified RPS ID to the another power adapter.

Techniques for processing a request may include: providing tasks to a state machine framework, wherein the tasks perform processing of a workflow for servicing the request; generating, by the state machine framework, a state machine for processing the request, wherein the state machine includes states associated with the tasks, wherein generating the state machine may include automatically determining a first state transition of the state machine between a first and a second of the states; receiving the request; and responsive to receiving the request, performing first processing using the state machine to service the request. The framework may automatically generate triggers that drive the state machine to determine subsequent states in accordance with defined state transitions. State machine internal state information may be persistently stored and used in restoring the state machine to one of its states in connection processing of the command.
