An information writing method is applied to an non-volatile dual in-line memory module (NVDIMM), the NVDIMM includes an NVDIMM controller and a non-volatile memory (NVM), and the method includes receiving, by the NVDIMM controller, a sanitize command from a host, where the sanitize command is used to instruct the NVDIMM controller to sanitize data in the NVM using a first write pattern, and the first write pattern is one of at least two patterns of writing information into the NVM, and writing, by the NVDIMM controller, information into the NVM according to the sanitize command.

Information writing method and apparatus

A memory access technology and a computer system, where the computer system includes a memory controller and a medium controller connected to the memory controller. In the computer system, when detecting that an error occurs in first data that is returned by the medium controller in response to a first send command, the memory controller determines sequence information of the first send command in a plurality of send commands that have been sent by the memory controller within a time period from a time point at which the first send command is sent to a current time, and sends a data retransmission command to the medium controller to instruct the medium controller to resend the first data based on the sequence information.

Memory access technology and computer system

An agent module of a host directs I/O requests accessing a first disk of a first storage array to access a second disk of a second storage array. The agent module obtains a disk identifier of a first disk in the first storage array and a disk identifier of a second disk in the second storage array to record a mapping relationship between them. The agent module further reports virtual path information for a virtual path between the agent module and a multipath module of the host to the multipath module. The agent module sends the disk identifier of the first disk via the virtual path after receiving a disk identifier query request for querying the identifier of the second disk. Thus, the agent module can send an I/O request for accessing the first disk to the second storage array to access the second disk.

I/O request processing method, storage array, and host

A vehicle body structure and a vehicle are provided. The vehicle body structure includes a front longitudinal beam, a front compartment crossbeam, and a floor front crossbeam. The front longitudinal beam includes a left front longitudinal beam and a right front longitudinal beam that are disposed at an interval in a transverse direction. The front longitudinal beam is provided with a body section and a downward bent section connected to a rear end of the body section. The front compartment crossbeam is connected to the downward bent section of the left front longitudinal beam and the right front longitudinal beam, and is at least partially located below the body section. The floor front crossbeam is located behind the front compartment crossbeam at an interval, and is connected to the front longitudinal beam.

A method is applied to a server and for providing a link priority between the server and a storage device. The server calculates an average latency of each of a plurality of links between the server and the storage device; then determines a latency interval to which the average latency of each link belongs; and determines a priority of each link based on a priority of the latency interval to which the average latency of each link belongs. At least two consecutive latency intervals are preset in the server, each latency interval represents a range of an average latency, and a priority is set for each latency interval. For latency intervals of adjacent priorities, a minimum latency value of a latency interval of a lower priority is greater than a maximum latency value of a latency interval of a higher priority.

Method and apparatus for setting link priority
