Embodiment Construction

[0048] See figure 1 , figure 1 It is a schematic diagram of the motherboard architecture of the storage server in the existing implementation.

[0049] Such as figure 1 As shown, the motherboard architecture of the storage server usually includes service IO ports, CPU, IOH (InputOutputHub, input-output hub), memory, SAS controller, SAS expander, and RAID array.

[0050] Among them, the CPU is responsible for the work related to the operating system, RAID algorithm and all business processing calculations. The IOH is the chipset supporting the CPU and is responsible for providing some low-speed interfaces; for example, management network ports, keys, and serial ports. The memory is used to provide a larger capacity and faster cache for the system; for example, the memory may be a DDR3 standard memory. The SAS controller is responsible for providing SAS protocol conversion and processing of related storage instructions. The SAS controller is responsible for expanding the nu...

Abstract

The invention provides a main board. The main board comprises a data read-write module based on an FPGA, a memory and a service port. The memory is connected with the data read-write module based on the FPGA. The service port is connected with a disk array in a storage server through the data read-write module. The data read-write module based on the FPGA is used for receiving an read-write IO request from the service port and issuing the received read-write IO request to the disk array; after the disk array executes read-write operation corresponding to the read-write IO request, the data read-write module based on the FPGA is further used for receiving an execution result returned by the disk array and corresponding to the read-write operation, and transmitting the execution result to an initiator host of the read-write IO request through the service port. The main board can improve the overall 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 (RandomAccessMemory, random access memory), and a very large internal disk space, so as to cope with the end-users at any time. 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. When reading and writing data, the CPU will receive data from the I / O service port. Read IO requests and write IO requests are sent to the disk array through the SAS controller and SAS expander, and the correspondin...
