Abstract: This application discloses a multi-device connection establishment method and a device. The method includes: A first device sends a first message, where the first message is used to discover another device; the first device receives one or more second messages from one or more devices, where the second message is a response message for the first message; the first device determines, based on the one or more second messages, to establish a connection to a second device in the one or more devices; and the first device negotiates, with the second device, link information used to establish direct communication between the first device and the second device, and establishes a direct communication connection to the second device based on the link information. After a communication connection is established between devices based on discovery, link information is negotiated, and direct communication is established based on the link information, to form a system. In this way, there is no need to allocate specific roles to the devices. Therefore, the roles of the devices in the established distributed system are equivalent, and a service is not limited to a role problem.

Abstract: A method of operating a computing system comprises defining a zoned namespace for non-volatile memory (NVM) of a memory device of the computing system, the zoned namespace including multiple NVM zones of multiple non-overlapping logical block addresses (LBAs) of the NVM, mapping persistence logging (PLOG) identifiers (IDs) to the NVM zones, a PLOG ID identifying a PLOG zone of one or more NVM zones, and performing a PLOG-specific access operation on a PLOG zone of the NVM in response to a PLOG-specific command received from a host device of the computing system.

Abstract: Write operation and garbage collection methods are provided for a Solid State Drive (SSD) controller of a SSD having Not-AND (NAND) flash memory devices with on-die Static Random Access Memory (SRAM) and NAND flash memory. In the write operation method, a received block of data is stored in on-die SRAM of the NAND flash device, rather than in on-chip SRAM of the controller, prior to programming into NAND flash memory. Until programmed into NAND flash memory, the block of data remains available in the on-die SRAM to fulfill an ‘immediate read’ operation, if received. In the garbage collection method, blocks of data are read from one or more source NAND flash devices and stored in on-die SRAM of a destination NAND flash device until a limit of such blocks has been reached, then the destination NAND flash device programs the blocks from the on-die SRAM into NAND flash memory.
