Description
Technical field
The present invention relates to server technology field, and in particular to a kind of redriver parameter configurations for server monitor
Method.
Background technology
When server product designs, high speed signal is more and more, and its demand to signal integrity is also relatively stricter.Have
In some designs, the cabling of high speed signal is long, in order that signal, in incoming terminal equipment, signal quality can be protected
Card, redriver chips are added more among cabling, signal is strengthened again after the loss of a segment distance.Due to
High speed signal quantity is excessive, often ensures signal link quality using multiple redriver in design.Redriver chips
Need to carry out debugging optimization according to the practical topology situation of circuit, choose optimal parameter.Redriver reads these parameters
To complete to configure.
The link of redriver parameter configurations in the prior art, multiple redriver are connected together by I2C, are connected to
There is each redriver configuration information on EEPROM, on EEPROM.Redriver 1 is just read after the completion of reset by I2C
Corresponding configuration information in EEPROM is taken to complete the configuration of itself, configuration sends loading to redriver 2 after completing and completes letter
Number, redriver 2 loads configuration information from EEPROM again after receiving the signal, by that analogy until redriver N.It is existing to set
The shortcomings that meter, is that, if the redriver for preferentially loading configuration information breaks down when can not load data, it can not be rearwards
Redriver send loading complete signal, redriver below also can not normal load data.And system can not also supervise
Control redriver failures.This is unfavorable for the reliability of server.
When single redriver loads data failure by I2C buses, may result in other redriver can not be normal
Load data.In addition redriver fails loading data, the problems such as high-speed link being caused obstructed, due to monitoring system without
Method knows this failure, and plant maintenance personnel need to expend very big energy investigation failure.
The content of the invention
The technical assignment of the present invention is to provide a kind of redriver parameter configuration monitoring methods for server, ensures single
When individual redriver breaks down, monitoring management system can be notified, and the influence brought is confined to believe corresponding to it
Number link, allows the equal normal work of other links.
The technical solution adopted for the present invention to solve the technical problems is：
A kind of redriver parameter configuration monitoring methods for server, have multiple redriver, and each redriver will
I2C buses are connected on the EEPROM containing redriver parameter informations；Redriver will load enable signal and loading is completed
Signal is connected on CPLD (CPLD), CPLD connections BMC；
When Redriver receives the loading enable signal of itself from CPLD, by I2C buses from EEPROM (with electric erasable and programmable
Journey read-only storage) in load the configuration parameter information of itself, sent when load completion and load completion signal to CPLD.
Further, CPLD first sends redriver 1 loading enable signal, and carry out simultaneously after completing to reset
Timing, if redriver1 sends loading before timing time arrival completes signal, indicate that the redriver normally completes data
Loading, then CPLD sends loading enable signal to next redriver；If redriver1 does not have before timing time arrival
Sending loading and complete signal, then CPLD closes the loading enable signal of the redriver, stops the data loading of the redriver,
And send loading enable signal to next redriver.
Further, if redriver1 does not send loading before timing time arrival completes signal, CPLD is to BMC
The sequence number of the redriver is sent, there occurs failure to indicate redriver loadings data.
Further, BMC recorded the CPLD fault messages sent in daily record.
The present invention a kind of redriver parameter configurations monitoring method for server compared with prior art, with
Lower beneficial effect：
Monitoring, the controlling mechanism of configuration information are loaded to redriver using CPLD, controls each redriver configuration information
Loading, and the redriver sequence numbers to go wrong are notified to the mechanism to BMC in time；
One redriver loading configuration data breaks down, and does not interfere with other redriver；There is event in redriver
During barrier, monitoring management system can detect failure and keep a record, and be easy to Breakdown Maintenance.
The present invention can be applied with being adjusted using redriver to high speed signal in all kinds of server systems of optimization.
Brief description of the drawings
Fig. 1 is the hardware link topology of the redriver parameter configuration monitoring methods for server.
Embodiment
With reference to specific embodiment, the invention will be further described.
A kind of redriver parameter configuration monitoring methods for server, there are multiple redriver, it is each
I2C buses are connected on the EEPROM containing redriver parameter informations by redriver；Redriver will load enable signal
Signal is completed with loading to be connected on CPLD, CPLD connections BMC.
When Redriver receives the loading enable signal of itself from CPLD, loaded certainly from EEPROM by I2C buses
The configuration parameter information of body, send to load when loading completion and complete signal to CPLD.
CPLD first sends redriver 1 loading enable signal, and carry out timing simultaneously after completing to reset.If
Redriver1 sends loading before timing time arrival and completes signal, and instruction redriver1 normally completes data loading, then
CPLD sends loading enable signal to next redriver.Add if redriver1 is not sent before timing time arrival
Carrying and complete signal, then CPLD closes redriver1 loading enable signal, stops redriver1 data loading, and to next
Individual redriver sends loading enable signal, according to this class support.
If redriver1 does not send loading before timing time arrival and completes signal, CPLD is sent to BMC should
Redriver sequence number, to indicate that the redriver loads data there occurs failure, BMC is by the logout into daily record.
The present invention is directed in the server high-speed signaling designs using multiple redriver, and a redriver loads number
According to failure, the problem of other redriver can be caused can not to load data, monitored using CPLD, control each redriver
Configuration information loading, when redriver loading configuration data breaks down, do not interfere with other redriver, and
And during redriver failures, monitoring management system can detect failure and keep a record, and be easy to Breakdown Maintenance.
By embodiment above, the those skilled in the art can readily realize the present invention.But should
Work as understanding, the present invention is not limited to above-mentioned embodiment.On the basis of disclosed embodiment, the technical field
Technical staff can be combined different technical characteristics, so as to realize different technical schemes.
