Description
Technical Field
The invention belongs to the technical field of BMC (baseboard management controller) data caching, and particularly relates to a data persistence method and system based on BMC.
Background
BMC, short for base Management Controller, substrate Management Controller.
The BMC manages the server mainboard through IPMI specifications, specifically comprises local and remote diagnosis, console support, configuration management, hardware management and fault removal, monitors the shutdown information of the server in the process of managing the server, such as monitoring the use conditions of a fan, a memory hard disk and other key components, and provides a better analysis basis and data support for the maintenance and fault processing of the server by monitoring the key information of the server. And the monitoring of the key information of the server is crucial to monitoring and analyzing the running state of the whole server, and the key information of the server comprises the following components: key voltage information, key temperature information, power consumption information. The key information of the early server is generally read by accessing actual equipment or reading database and configuration file information, and in such a way, the data return time is long and the data acquisition speed is slow. The data cache can be adopted at present to rapidly acquire the monitoring data, thereby rapidly and accurately processing the problems,
the existing data caching method of BMC comprises the following steps: the data is firstly stored in a database or a configuration file, then the cache is updated, and the data is directly obtained from the cache when being read, so that the access speed is improved. However, sometimes, after the database is successfully inserted or the configuration file is updated, if a cache has a problem or a cache system is hung, a client request can directly access the latest data of the database, so that when the cache is recovered, concurrent requests can access the old cache data, and an inconsistency problem occurs at this time; in addition, when the cache is restored, the cache is usually directly emptied and then the cache content is reloaded, but actually, a large part of cache data is not changed frequently, such as some in-place information, user information, FRU information, and the like, and the method of completely emptying and reloading the cache is very inefficient.
This is a disadvantage of the prior art, and therefore, it is very necessary to provide a BMC-based data persistence method and system for the above-mentioned disadvantages of the prior art.
Disclosure of Invention
The invention provides a data persistence method and system based on BMC (baseboard management controller), aiming at the defects that in the prior art, when the BMC stores data in a cache for reading by a user, and the cache fails and is recovered, the data read from the cache is not the latest data, the data is inconsistent, and the efficiency of completely reloading the cache data is low.
In a first aspect, the present invention provides a BMC-based data persistence method, including the following steps:
s1, setting BMC monitoring server key information, and writing the received server key information into a storage module and a cache at the same time;
s2, the storage module sets an updating state for each piece of server key information and records whether the writing into the cache is successful or not;
s3, setting an access switch in the cache; when the key information of the server is written into the cache and fails, closing the cache access switch;
s4, detecting whether the cache is available or not at regular time after the cache access switch is closed;
when the cache is available, updating the cache according to the update state of the key information of the server in the storage module, and turning on a cache access switch.
Further, the method also comprises the following steps:
s5, when the client reads the key information of the server monitored by the BMC, judging whether a cache access switch is turned on;
if yes, reading key information of the server from the cache;
if not, the key information of the server is read from the storage module. By setting the cache access switch, the recovery position after the cache failure is avoided, and old cache data is read from the cache, so that data inconsistency occurs.
Further, the server key information includes voltage information, temperature information, and power consumption information.
Further, the storage module adopts a database or a configuration file;
the step S2 comprises the following specific steps:
s21, judging whether the storage module is a database or a configuration file;
when the storage module is a database, the step S22 is carried out;
when the storage module is a configuration file, the step S23 is carried out;
s22, adding a state table in the database, recording whether the key information of the corresponding server is updated to a cache by the state table, and entering the step S3;
s23, adding state configuration in the configuration file, judging whether the key information of the corresponding server of the state configuration record is updated to the cache or not, and entering the step S3. The storage module can adopt one of two modes of a database or a configuration file, and each mode can set and record the update state that the BMC reads the key information of the server and updates the key information to the cache.
Further, the step S3 specifically includes the following steps:
s31, setting an access switch in the cache, and setting the default cache access switch to be in an on state;
s32, judging whether the BMC successfully writes the key information of the server into the cache;
if yes, entering step S5;
if not, judging that the cache is unavailable, closing a cache access switch, and entering the step S4. Whether the cache is available or not is controlled through the cache access switch, when the BMC fails to write the key information of the server into the cache, the cache can be judged to be unavailable, the cache access switch is closed, and the user is prevented from reading wrong data.
Further, the step S4 specifically includes the following steps:
s41, after the cache access switch is turned off, the step S5 is carried out, timing is set at the background, and cache detection is carried out at set time intervals;
s42, detecting whether the cache is available;
if yes, go to step S43;
if not, returning to the step S42;
s43, obtaining server key information with an update state of write-in cache failure in the storage module, and updating the cache;
and S44, opening a cache access switch. After the cache access switch is closed, whether the cache is recovered due to failure needs to be detected regularly, after the cache is recovered due to failure, the cache data is updated in time according to the updating state, and then the cache access switch is opened for the user to use, so that the user is prevented from reading wrong data, meanwhile, all data does not need to be updated, and only the server key information of which the updating state is write-in cache failure needs to be updated.
