A data reading and writing method and main board

Abstract

The application provides a mainboard, applied to a storage server, and the mainboard comprises a CPU, a data read and write module based on an FPGA, and a memory. The data read and write module based on the FPGA is separately connected to the CPU and a disk array of the storage server. The memory is connected to the data read and write module based on the FPGA. The data read and write module based on the FPGA is configured to receive a read and write IO request delivered by the CPU, analyze the read and write IO request, to obtain a corresponding read and write address, and determine whether the obtained read and write address hits an address index in a preset hotspot database in the memory; and when the obtained read and write address hits the address index in the preset hotspot database, based on hotspot data in the hotspot database, locally perform a read and write operation corresponding to the read and write IO request. The mainboard can improve an access speed of the hotspot data and whole read and write performance of the storage server.

Description

technical field [0001] The present application relates to the communication field, in particular to a method for reading and writing data and a mainboard. Background technique [0002] A storage server is a server that can provide a large storage space. It must have a fast processing chip, a large RAM (Random Access Memory, random access memory), and a very large internal disk space, in order to deal with end users at any time. Possible application deployment needs. [0003] In storage servers, the motherboard is usually the heart of a storage server design. In the existing architecture of the storage server motherboard, the CPU usually establishes a connection with the disk array through a SAS (Serial Attached SCSI, serial SCSI technology) controller and a SAS expander. The port receives read IO requests and write IO requests and sends them to the disk array through the SAS controller and SAS expander to complete the corresponding read and write operations. [0004] When...

AI Technical Summary

Problems solved by technology

In practical applications, when the disk is reading and writing data, the head seek time and the rotation delay time are usually relatively long. If the CPU frequently accesses the disk, most of the disk work is spent on seeking, and the work efficiency will be very low. Causes the entire computing system to run slowly, so it is necessary to accelerate disk access
