Description

Design method of server asset information management based on I2C link exchange

technical field

The invention relates to the field of computer communication asset management, in particular to a design method for rack server asset information management based on I2C link exchange.

technical background

Today's server systems have higher and higher requirements for asset information acquisition. Server asset information management needs to collect asset data of each server node in real time, and make early warning and change processing for abnormal asset changes. Server asset information management requires each node to participate in the polling response and provide the asset information of the node;

With the increase of server nodes, the dynamic response capability required for server asset information management is getting faster and faster. While completing the fast polling response, there is a higher demand for abnormal asset change management. Quickly make information feedback and record the changed content in real time. At present, the asset management of multi-node server systems mostly relies on manual recording and statistics. This method has low statistical efficiency, low data accuracy, and cannot achieve real-time performance. Today, a large number of server nodes are connected to the network. How to realize the effective management of server asset information in a multi-node environment is of great significance to the stability of server asset operation and maintenance.

In view of the current statistical efficiency of server asset information management is low, data accuracy is not high, and can not achieve real-time problems, currently only through manual computer room management, through the manual recording of node information to establish a maintenance form, and regularly update Abnormal changes in tables and nodes can only be obtained by artificially comparing node information, which cannot achieve consistent accuracy; as the reliability requirements of the server system continue to increase, in order to ensure the stability of server operation and maintenance, high-intensity operation on multiple nodes In the process, stable and effective asset management design is particularly important, and has become one of the key elements to determine the stability of server operation.

Contents of the invention

The technical problem to be solved by the present invention is: the present invention is based on the support of the bus arbitration theory, and specifically uses a rack server asset information management design method based on I2C link exchange to solve the asset management of the current multi-node server system Most of them rely on the problems of low statistical efficiency, low data accuracy and inability to achieve real-time asset monitoring in manual records.

The technical solution adopted in the present invention is: a method for designing server asset information management based on I2C link exchange, including the following steps:

①Establish the I2C link communication center, that is, the master control end of the I2C link, to issue and collect information, complete management, etc. Since there are many server nodes, the master control end of the I2C link needs to issue six master control I2C links to be compatible with as many server nodes as possible.

②I2C link exchange adopts two-level control transmission. The first level uses programmable controllers to realize I2C multiplexing, that is, realizes one-way to four-way switching. The second level uses programmable controllers to realize I2C node communication multiplexing. That is to realize one-way to eight-way switching.

③ After the two-stage I2C link control transmission, the signal of the I2C link has begun to deteriorate, and waveform reflection, waveform level fluctuation, and weakened drive capability have occurred. Therefore, data buffering and signal drive enhancement are required. Signal reflection, The floating and driving capabilities are both improved and controlled to achieve optimal I2C link control.

④ After two-stage transmission and signal drive capability enhancement, the I2C link communication center, that is, the master control end of the I2C link first opens the first group of six-way master control I2C links, and the first group of master control links Send the first-level multiplexing open command in the first-level multiplexer to open the first channel of the first-level multiplexer; then send the second-level multiplexer open command in the first group of master links to open the second-level multiplexer The first channel of the conversion, thus forming the first group of links --- the first channel of the first-level multiplex conversion --- the link channel of the first channel of the second-level multiplex conversion, through the link node The I2C channel of the channel can read the information of the node on the channel.

The establishment of the I2C link communication center, that is, the master control end of the I2C link, is used to send and collect information, complete management, and the like. The I2C link communication center is the ARM embedded controller, which completes the I2C link switching, read and write control, etc., and completes the polling and reading of assets at the same time. Due to the large number of server nodes, the main control end of the I2C link, that is, the ARM embedded controller, needs to send more than six main control I2C links to be compatible with as many server nodes as possible.

The I2C link exchange adopts two-level control transmission. The first level uses a programmable controller to realize I2C multi-channel conversion, that is, realizes one-way to four-way switching, and the second level uses a programmable controller to realize multiple I2C node communications. Road conversion, that is, to realize one-way to eight-way switching. Multi-channel switching is internal address switching, that is, the main control terminal needs to send a channel switching command. The content of the command includes the address of the channel and the opening status of the channel; after the first-level control transmission is opened, the second-level control is opened in sequence.

After the above-mentioned two-stage I2C link control transmission, the signal of the I2C link has begun to deteriorate, and waveform reflection, waveform level floating, and driving capability are weakened. Therefore, the I2C link driver PCA9517 is used for data buffering and signal processing. The drive is strengthened, and the reflection, floating and driving capabilities of the signal are improved and controlled. The signal plays an isolation role and achieves the optimal I2C link control.

The formation method of the link needs to open the I2C link channel step by step. Since the master control end of the I2C link has six main control I2C links, the first-level control transfer realizes one-way to four-way switching, and the second-level control transfer realizes one-way Turn to eight-way switch. In this way, a total of 192 I2C channels of 6X4X8 are formed, and 192 node asset data can be detected to achieve maximum I2C link control.

The current mainstream ARM9 embedded controller can be used to establish the I2C link communication center, that is, the master control end of the I2C link, to send and collect information, complete management, etc. The master control end of the I2C link sends out six master control I2C links, compatible with 192 server nodes.

The I2C link exchange adopts two-level control transmission. The first level uses the programmable controller EPM240T100C5N to realize I2C multi-channel conversion, that is, realizes one-way to four-way switching. The second level uses the programmable controller EPM240T100C5N to realize I2C node communication. Multi-channel conversion, that is, to realize one-way to eight-way switching.

After the two-stage I2C link control transmission, PCA9517 can be used to buffer data and strengthen signal drive to achieve optimal I2C link control.

After two-stage transmission and signal drive capability enhancement, the I2C link communication center opens the control channel step by step, and polls and reads the asset information of the nodes.

The beneficial effect of the present invention is: by implementing the technology of the present invention, the asset information of the server can be obtained very conveniently, which not only meets the high efficiency requirement, but also realizes the real-time requirement of the acquisition method, improves the efficiency and accuracy of asset information transmission, Improve the asset management reliability and stability of the server system.
