The first embodiment is as follows:
the embodiment provides a dynamic capacity-expansion storage method, which operates based on a dynamic capacity-expansion storage system, where the dynamic capacity-expansion storage system includes a registration server, a load balancing server, a storage proxy server, a storage router, a database server, and a storage management center. As shown in fig. 1, the method comprises the following steps:
and S1, the register server receives the register request sent by the user terminal, distributes the register UID for the register request, and sends the register request and the register UID to the storage proxy server through the load balancing server. The load balancing server is used for carrying out load balancing distribution and distributing the registration request and the registration UID of the user to the storage proxy server in a balancing way, so that the response speed of the whole system is ensured.
The step S1 specifically includes:
the registration server receives a registration request sent by a user side, sends the registration request to the cache server, and receives a new user judgment result fed back by the cache server; the cache server is part of the database server and stores part of the user information, such as the user ID. The cache server is used for identifying whether the user side sending the registration request is a new user, if the user ID of the user side is stored, the user side is registered, and if the user ID of the user side is not stored, the user side is not registered.
And after determining that the new user is the registered user according to the judgment result of the new user, the registration server sends the registration request and the registration UID to the storage proxy server through the load balancing server, the storage proxy server sends the registration request and the registration UID to the rear end for storage, and if the new user is not the registered user, the registered information is fed back to the user side. Therefore, the storage space waste caused by repeated storage of user registration data is avoided.
And S2, the storage proxy server sends the registration request and the registration UID to the database server for storage through the storage route, and reports the registration UID to the storage management center. The database server comprises a plurality of data devices for storing data, a storage node corresponding to each data device is arranged in the storage route, and the storage route sends the registration request to the data devices for storage according to the storage nodes. The registration UID is identity information distributed by the system for the registration request.
And S3, calculating the residual storage capacity of the database after the storage management center receives the registered UID, applying for a storage node from the operation and maintenance terminal to enlarge the capacity of the database server when the residual storage capacity is smaller than the threshold capacity, and adding the applied storage node to the storage route.
The step S3 specifically includes:
and after receiving the registered UID, the storage management center calculates the occupied storage capacity of the database server.
And the storage management center subtracts the occupied storage capacity according to the total storage capacity of the database server to obtain the residual storage capacity. For example, if the total allocated storage capacity of the database server is 100 billion and the currently allocated uid is 90 billion, the management center can calculate the remaining 10 billion storage space.
The storage management center judges whether the residual storage capacity is smaller than the threshold capacity, if so, the storage management center sends a storage node application to the operation and maintenance end and receives storage node distribution information fed back by the operation and maintenance end; after receiving the storage node application, the operation and maintenance terminal allocates the redundant data equipment to the database server to enlarge the capacity of the database server, and then transmits the storage node allocation information of the data equipment to the storage management center.
The storage management center performs base table initialization operation on the newly distributed data equipment according to the storage node distribution information, and adds the initialized base table information as a storage node to a storage route; after the storage node of the newly added data device is added to the storage route, the storage proxy server can store the data to the newly added data device through the storage route.
And the storage management center obtains the newly added storage capacity according to the storage node distribution information and updates the total storage capacity according to the newly added storage capacity. And adding the previous total storage capacity to the newly added storage capacity to obtain a new total storage capacity so as to carry out calculation next time.
In summary, the present embodiment has the following advantages compared to the conventional storage scheme:
firstly, manual expansion is not needed, and the method is more efficient. The labor cost is saved, the error of manual expansion is avoided, and the storage is more efficient.
And secondly, the utilization value of the hardware is improved, and the early waste of the hardware is avoided. The traditional manual capacity expansion needs to provide sufficient storage very early, and the capacity expansion is carried out once, so that early-stage hardware is idle; the dynamic capacity expansion processing is to apply for storage immediately before the storage reaches the maximum storage, and to put the storage into use after necessary initialization, thereby bringing about full use of hardware.
Example two:

and the registration server is used for receiving the registration request sent by the user side, distributing the registration UID for the registration request, and sending the registration request and the registration UID to the storage proxy server through the load balancing server. The load balancing server is used for carrying out load balancing distribution and distributing the registration request of the user to the storage proxy server in a balancing manner, so that the response speed of the whole system is ensured.
Specifically, a registration server receives a registration request sent by a user side, sends the registration request to a cache server, and receives a new user judgment result fed back by the cache server; the cache server is part of the database server and stores part of the user information, such as the user ID. The cache server is used for identifying whether the user side sending the registration request is a new user, if the user ID of the user side is stored, the user side is registered, and if the user ID of the user side is not stored, the user side is not registered.
And after determining that the new user is the registered user according to the judgment result of the new user, the registration server sends the registration request and the registration UID to the storage proxy server through the load balancing server, the storage proxy server sends the registration request and the registration UID to the rear end for storage, and if the new user is not the registered user, the registered information is fed back to the user side. Therefore, the storage space waste caused by repeated storage of user registration data is avoided.
And the storage proxy server is used for sending the registration request and the registration UID to the database server for storage through the storage route and reporting the registration UID to the storage management center. The database server comprises a plurality of data devices for storing data, a storage node corresponding to each data device is arranged in the storage route, and the storage route sends the registration request to the data devices for storage according to the storage nodes. The registration UID is identity information distributed by the system for the registration request.
And the storage management center is used for calculating the residual storage capacity of the database after receiving the registered UID, applying for a storage node from the operation and maintenance end to enlarge the capacity of the database server when the residual storage capacity is smaller than the threshold capacity, and adding the applied storage node to a storage route.
Specifically, after receiving the registered UID, the storage management center calculates the occupied storage capacity of the database server.
And the storage management center subtracts the occupied storage capacity according to the total storage capacity of the database server to obtain the residual storage capacity. For example, if the total allocated storage capacity of the database server is 100 billion and the currently allocated uid is 90 billion, the management center can calculate the remaining 10 billion storage space.
The storage management center judges whether the residual storage capacity is smaller than the threshold capacity, if so, the storage management center sends a storage node application to the operation and maintenance end and receives storage node distribution information fed back by the operation and maintenance end; .
And the storage management center performs base table initialization operation on the newly distributed data equipment according to the storage node distribution information, and adds the initialized base table information serving as the storage node to the storage route. After the storage node of the newly added data device is added to the storage route, the storage proxy server can store the data to the newly added data device through the storage route.
And the storage management center obtains the newly added storage capacity according to the storage node distribution information and updates the total storage capacity according to the newly added storage capacity. And adding the previous total storage capacity to the newly added storage capacity to obtain a new total storage capacity so as to carry out calculation next time.
In summary, the present embodiment has the following advantages compared to the conventional storage scheme:
firstly, manual expansion is not needed, and the method is more efficient. The labor cost is saved, the error of manual expansion is avoided, and the storage is more efficient.
And secondly, the utilization value of the hardware is improved, and the early waste of the hardware is avoided. The traditional manual capacity expansion needs to provide sufficient storage very early, and the capacity expansion is carried out once, so that early-stage hardware is idle; the dynamic capacity expansion processing is to apply for storage immediately before the storage reaches the maximum storage, and to put the storage into use after necessary initialization, thereby bringing about full use of hardware.
