摘要:
Provided are a computer program product, system, and method to allow a host and a storage device to communicate using different fabric, transport, and direct memory access protocols. An origination package is received from an originating node at a first physical interface over a first network to a destination node having a storage device including a first fabric layer encoded according to a first fabric protocol, a first transport layer encoded according to a first transport protocol including a storage Input/Output (I/O) request directed to the storage device at the destination node. At least one destination packet is encoded with a second fabric layer and a second protocol layer according to the first fabric protocol or a second fabric protocol and according to the first transport protocol or a second transport protocol depending on what the destination node uses.

A host computer includes a virtual machine including a device-specific nonvolatile memory interface (NVMI). A nonvolatile memory virtualization abstraction layer (NVMVAL) hardware device communicates with the device-specific NVMI of the virtual machine. A NVMVAL driver is executed by the host computer and communicates with the NVMVAL hardware device. The NVMVAL hardware device advertises a local NVM device to the device-specific NVMI of the virtual machine. The NVMVAL hardware device and the NVMVAL driver are configured to virtualize access by the virtual machine to remote NVM that is remote from the virtual machine as if the remote NVM is local to the virtual machine.

A cryptographic device (100) comprising - a non-volatile memory (110), a range (220; 322; 364) of the memory storing data, a selector (125) arranged to receive a selector signal (121) configuring a memory read-out unit for a regular read-out mode or for a PUF read-out mode of the same memory, - a control unit (130) arranged to send the selector signal to the selector configuring the memory read-out unit in the regular read-out mode, and reading the memory range to obtain the data, and send the selector signal to the selector configuring the memory read-out unit for PUF read-out mode, and obtaining a noisy bit string from the memory range.
摘要:
A solid-state drive may be coupled via an interface with a processing device that receives an indication of a failure of a logical unit of a non-volatile memory of the solid-state drive. In response to the indication of the failure, parity data at locations of other logical units of the nonvolatile memory of the solid-state drive may be identified. User data from the logical unit may be reconstructed based on the parity data from the locations of the other logical units of the nonvolatile memory of the solid-state drive. Furthermore, the reconstructed user data from the logical unit may be stored at the locations of the other logical units that store the parity data.
摘要:
A processor-based method for flash-friendly caching is provided. The method includes reading data from a first memory and writing the data to a second memory, in a cache. The method includes performing an aligned block write of data from the second memory in the cache to a flash memory in the cache, responsive to accumulating sufficient data for the aligned block write.
摘要:
Technology for an apparatus is described. The apparatus can include a memory controller with circuitry configured to initiate a program verify sequence to verify data written to a non-volatile memory (NVM). The program verify sequence can have one or more program verify levels that each correspond to memory cells in the NVM for which written data is being verified. The memory controller can detect an approximate percentage of memory cells for each program verify level in which data is successfully written. The memory controller can determine to skip subsequent program pulse verification checks in one or more program verify levels when the approximate percentage of memory cells in which data is successfully written is less than a defined threshold.

A method for updating data in a distributed storage system is disclosed. The method may comprise receiving, by a sender terminal device, an update request; obtaining, by the sender terminal device, update data and control information from the update request; sending, by the sender terminal device, the update data, via a data update request, to a receiver terminal device; and sending, by the sender terminal device, the control information, via a control information update request, to the receiver terminal device.
摘要:
A security framework for a multi-tenant, multi-tier computer system with embedded processing is described. A multi-tenant security framework is created for a combined processing and storage hierarchy of multiple tiers. The multi-tenant security framework is applied to multiple execution levels of the memory device. The multi-tenant security framework is applied to multiple layers of application server software of the memory device. The multi-tenant security framework is also applied to multiple layers of storage server software of the memory device.
摘要:
Systems, methods and/or devices are used to reduce declared capacity of non-volatile memory of a storage device in a storage system. In one aspect, the method includes, detecting an amelioration trigger for reducing declared capacity of non- volatile memory of a storage device, and in accordance with the detected amelioration trigger, performing an amelioration process to reduce declared capacity of the non-volatile memory of the storage device, the performing including: moving a portion of data used by a host from the storage device to another storage device of the storage system, and reducing declared capacity of the non- volatile memory of the storage device. In some embodiments, the storage device includes one or more flash memory devices. In some embodiments, the detecting, the performing, or both are performed by the storage device, or by one or more subsystems of the storage system distinct from the storage device, or by the host.
