Abstract: A storage space management method and apparatus, where the method and apparatus are applied to a non-volatile memory (NVM). In a feature set that includes M image features of M idle blocks in storage space of the NVM, an idle block whose image feature is highly similar to an image feature of data to be written into the NVM is determined such that the data is written into the idle block. In this way, wear and energy consumption problems are considered during storage space allocation, and a write operation of an idle block in storage space of an NVM can consume less energy, thereby extending a life span of the NVM and reducing write operation energy consumption.

Abstract: A file management method, a distributed storage system, and a management node are disclosed. In the distributed storage system, after receiving a file creation request sent by a host for requesting to create a file in a distributed storage system, a management node allocates, to the file, first virtual space from global virtual address space of the distributed storage system, where local virtual address space of each storage node in the distributed storage system is corresponding to a part of the global virtual address space. Then, the management node records metadata of the file, where the metadata of the file includes information about the first virtual space, and the information about the first virtual space is used to point to local virtual address space of a storage node that is used to store the file. Further, the management node sends, the information about the first virtual space to the host.

Abstract: A processing node, a computer system, and a transaction conflict detection method, where the processing node includes a processor and a transactional cache. When obtaining a first operation instruction in a transaction for accessing shared data, the processor accesses the transactional cache for caching shared data of a transaction processed by the processing node. If the transactional cache determines that the first operation instruction fails to hit a cache line in the transactional cache, the transactional cache sends a first destination address in the operation instruction to a transactional cache in another processing node. After receiving status information of a cache line hit by the first destination address from the other processing node, the transactional cache determines, based on the received status information, whether the first operation instruction conflicts with a second operation instruction executed by the other processing node.

Abstract: A file access method and apparatus, and a storage device are presented, where the file access method is applied to a storage device in which a file system is established based on a memory. The storage device obtains, according to a file identifier of a to-be-accessed first target file, an index node of the first target file in metadata, where the index node of the first target file stores information about first virtual space of the first target file in global virtual space. The storage device maps the first virtual space onto second virtual space of a process, and performs addressing on an added file management register to access the first target file according to a start address of the first virtual space and a base address of a page directory of the global file page table stored in the file management register.

Abstract: The disclosure relates to technology for secure compute. One aspect includes a network device, comprising a non-transitory memory comprising instructions; and one or more processors in communication with the non-transitory memory storage. The one or more processors execute the instructions to receive and process routing requests in a network; send an indication into the network that the network device is able to perform secure computes; perform a secure compute based on an input received via the network from an input device; ensure that a result of the secure compute is trusted as a correct result of the secure compute; and provide the trusted result of the secure compute to a result device connected to the network.

Abstract: A storage system includes a management node and a plurality of storage nodes forming a redundant array of independent disks (RAID). When the management node determines that not all data in an entire stripe is updated based on a received write request, the management node sends an update data chunk obtained from to-be-written data to a corresponding storage node. The storage node does not directly update, based on the received update data chunk, a data block stored in a storage device of the storage node, but store the update data chunk into a non-volatile memories (NVM) cache of the storage node and send the update data chunk to another storage node for backup. According to the data updating method, write amplification problems caused in a stripe update process can be reduced, thereby improving update performance of the storage system.
