Embodiment Construction

[0018] The content of the present invention is described in more detail below:

[0019] ①Establish the SAS dynamic transmission reconstruction unit. The SAS dynamic transmission reconstruction unit is realized by FPGA with PCIE hard core, and the PCIE2.0 X8 bandwidth bus is connected to the CPU PCIE controller to realize the main data communication path.

[0020] ② Connect the SAS dynamic transmission reconstruction unit to the South Bridge PCH chip on the main board through the LPC bus and the data selection switch to realize the communication path of reconstruction management data.

[0021] ③When the server is running, the SAS dynamic transmission reconstruction unit is first initialized to the direct connection mode, and at the same time starts the data capture process, analyzes the read-write ratio and the size of the data, and makes statistics on the amount of data per unit time to obtain the current SAS data Statistical laws of transmission.

[0022] ④According to the a...

Abstract

The invention provides a SAS transmission performance acceleration method for server dynamic resource reconstruction, which belongs to the field of computer communication. The invention establishes a SAS dynamic transmission reconstruction unit and connects it to a CPU through a PCIE bus; the SAS dynamic transmission reconstruction unit passes through an LPC bus. Connected to the south bridge PCH chip on the motherboard, during the running of the server, the SAS dynamic transmission reconstruction unit is first initialized to the direct connection mode, and at the same time starts the data capture process, analyzes the read-write ratio and the size of the data, and converts the The data volume is counted, and according to the statistical law of the current SAS data transmission obtained, the transmission unit is automatically reconstructed, and the data storage is automatically striped. At the same time, the data transmission cache space is established according to the delay of data transmission to achieve optimal SAS transmission reconstruction unit; adjust and optimize the packet sending parameters of the driver layer to achieve the optimal data transmission path.

Description

technical field [0001] The invention relates to the field of computer communication, and specifically uses a SAS transmission performance acceleration method for server dynamic resource reconstruction to solve the current problem that the data transmission performance of the server SAS expansion card gradually becomes the bottleneck of the system performance in the current server system. Background technique [0002] The performance requirements of today's server systems are getting higher and higher, and the throughput of the input and output data of the server motherboard is increasing. The data throughput includes the transmission of local storage data and external network data transmission. The server motherboard is designed with 2-6 PCIE bus slots to expand the corresponding storage or network sub-cards; for a standard server system, the above two types of sub-cards are essential, and the transmission performance of the server is also important. Embodied in the two type...
