Embodiment 1

[0035] Such as figure 2 As shown, the present invention provides a kind of management system of server I2C equipment, comprises: some from equipment 1, BMC2 and CPLD3, each I2C is all connected with the failure signal input end of BMC2 from the failure signal output end of equipment 1, each The reset signal input terminals of each I2C slave device 1 are connected to the reset signal output terminal of CPLD3, and BMC2 communicates with CPLD3 through one I2C bus.

[0036] Further, the management system in this solution also includes efuse chip 4, the enable signal output end of CPLD3 is connected with the enable signal receiving end of efuse chip 4, and the power control output end of efuse chip 4 is connected with the power control output end of I2C slave device 1. input connection.

[0037] Because some I2C slave devices do not have a separate reset terminal, it is necessary to use the efuse chip to control the power supply of the I2C slave device, so that it can be powered ...

Embodiment 2

[0040] Such as image 3 As shown, the technical solution of the present invention also provides a management method for the I2C device of the server, which is implemented on the basis of Embodiment 1 of the technical solution of the present invention, and specifically includes:

[0041] S1. When the BMC detects that a certain I2C link is dead, the BMC transmits the I2C link information to the CPLD through the I2C bus, and the CPLD determines the corresponding I2C link through the I2C link information. According to the I2C link and the I2C slave Device correspondence, reset the I2C slave devices in the I2C link in turn;

[0042] S2. The BMC polls to detect whether the I2C link is recovered. If it detects that the I2C link has recovered, the BMC sends a message, and the CPLD stops resetting the I2C slave device in the I2C link.

[0043] Wherein, in step S1, the corresponding relationship between I2C link and I2C slave device is pre-stored in the UFM of CPLD (the Flash area prov...

Embodiment 3

[0049] Such as Figure 4 As shown, the technical solution of the present invention also provides a management method of a server I2C device, which specifically includes:

[0050] S1. When the BMC detects that a certain I2C link is dead, the BMC transmits the I2C link information to the CPLD through the I2C bus, and the CPLD determines the corresponding I2C link through the I2C link information. According to the I2C link and the I2C slave Device correspondence, reset the I2C slave devices in the I2C link in turn;

[0051] S2, the BMC polls to detect whether the I2C link is restored, if it is detected that the I2C link has been replied, the BMC sends information, and the CPLD stops resetting the I2C slave device in the I2C link;

[0052] S3, the UFM of the CPLD also stores the number of problems of the I2C slave device. When the BMC polls and detects that the I2C link has recovered, the CPLD will add 1 to the number of problems of the last I2C slave device operated before the I...

Abstract

The invention aims to solve the problems in the prior art, and innovatively provides a management system and method for server I2C equipment. Based on the existing I2C topology, the advantage of richpin resources of the CPLD is utilized, a reset signal or a power supply control signal of the I2C slave device is connected to the CPLD; meanwhile, the BMC and the CPLD are modified; therefore, independent management of a plurality of I2C slave devices on one I2C bus is achieved; the problem that the whole I2C link is suspended due to the problem of individual I2C slave equipment is effectively solved; the management of the I2C slave equipment is perfected; the management efficiency of the I2C slave device is improved; according to the method and system, the CPLD can record the number of timesthat each I2C slave device goes wrong, and after the number of times reaches the set threshold value, the CPLD can send alarm information to the BMC to be processed in time, so that the stability andmaintainability of a server product are enhanced.

Description

technical field [0001] The invention relates to the field of I2C equipment management, in particular to a management system and method for I2C equipment of a server. Background technique [0002] As the server industry matures, server products emerge in endlessly. However, the mainstream architecture of the server is still BMC+CPLD+PCH+CPU, and the most widely used bus is still the I2C bus. Among them, the BMC mainly manages the I2C slave devices through the I2C bus. These include PSU (power supply), I2C Switch, FRU (Field Replace Unit, field replaceable unit), Thermal Sensor (temperature sensor), etc. It is obvious that the BMC and I2C bus play a vital role in the management of the server. [0003] However, in the existing design, the BMC only includes 14 I2C channels, but there are more than 14 I2C slave devices. Therefore, one I2C link of the BMC often cascades multiple I2C slave devices. Such as figure 1 As shown, the design topology of a BMC I2C link in the current...
