Problems solved by technology

After the CPU (Central Processing Unit, central processing unit) sends a data request, if any link between the CPU and PSX (PCIe SwitchX, X represents the series) changes, the MRPC (Memory-mapped Remote Procedure Calls, Microchip proposed) that returns to the CPU A chassis management calling method using its Switch product) data may contain 0xff illegal data, but the current transmission protocol cannot recognize the illegal data, causing the CPU to parse the illegal data as normal data, get wrong parsing results, and output errors control commands, which may cause faults such as abnormal temperature and abnormal fan speed, which seriously affect the operation of the storage system.

Abstract

The present application discloses an MRPC data processing method, system, device and computer-readable storage medium, and relates to the field of storage. The MRPC data processing method includes: determining a root port of a PSX based on a PCIe connection topology; controlling the CPU utilization corresponding to the root port The completion timeout mechanism monitors the read status of MRPC data; when the read status is the timeout status, the read MRPC data is discarded. The present application can avoid wrong responses to wrong MRPC data parsed by the CPU, and ensure the normal operation of the storage system.

Description

technical field [0001] The present application relates to the field of storage, and in particular, to an MRPC data processing method, system and related components. Background technique [0002] In the field of storage, with the popularity of Nvme (Non-Volatile Memory Express, non-volatile memory host controller interface specification) SSD (Solid State Disk, solid-state drive), based on PCIe (Peripheral Component Interconnect Express, high-speed serial computer expansion bus Standard) directly connected disk enclosures have also developed, and the storage controller uses PCIe cables (usually MiniSasHD cables) to connect hard disk expansion enclosures and disk enclosures. In order to meet the performance requirements, the bandwidth of the PCIe cable between the storage controller and the hard disk expansion enclosure is generally above x16, while the common MiniSasHD cable is x4. Therefore, multiple MiniSasHD cables are often used to connect the storage controller and the ha...
