Abstract: The present application discloses a Hamming weight calculation method performed by an operation apparatus. The operation apparatus includes a controller and a first calculator, wherein the controller sets an initial resistance state of the first memory to a low resistance state; determines a first gate voltage of the first transistor based on first bit data in a first binary sequence, and control an on-off state of the first transistor based on the first gate voltage; controls a target resistance state of the first memory based on the on-off state of the first transistor; and determines a Hamming weight of the first bit data based on a first output current on the source of the first transistor.

Abstract: In an active-active system, if write lock permission is granted to a second storage array, a first storage array sends to-be-written data and a lock revocation request together to a lock server; the lock server sends a lock revocation request carrying the to-be-written data to the second storage array; after storing the to-be-written data, the second storage array sends a lock revocation success message to the lock server; the lock server gives the write lock permission to the first storage array; and the first storage array obtains the write lock permission and stores the to-be-written data.

Abstract: Application relates to storage technologies, and in particular, to writing data in a storage system having solid state disks. Embodiments of the application provide an array controller, including a communication interface and a processor. The processor receives information about a logical block from a solid state disk. The information about the logical block includes a size of the logical block and indication information of the logical block, and the logical block includes one or more physical blocks. The processor sends multiple write data requests to the solid state disk. Each write data request includes data, and each write data request instructs the solid state disk to write the data into the logical block indicated by the indication information of the logical block. A total size of data included in the multiple write data requests is equivalent to the size of the logical block.
