Abstract
The invention relates to a dynamic server dilatation system and method. A load equalizer monitors the load of a storage server and sends a dilatation request instruction to a management server when the load of the storage server exceeds a preset value. The management server sends dilatation address information to the load equalizer after receiving the dilatation request instruction. The load equalizer establishes a communication connection with a dilatation server according to the dilatation address information and adjusts the load of the storage server to the dilatation server. After the overload of the storage server is detected, the load of the overload server is adjusted to the dilatation server to avoid an undercapacity of the disk of the server. During dilatation of the server, influence on normal operation of a website and normal access of a user can be avoided, and limitations to the model and the capacity of the disk of the server also can be reduced; as a result, potential safety hazards caused to the data of the server in the dilatation process are effectively relieved, and the operation reliability is high; besides, the dilatation method is simple and easy to implement, and convenient for dynamic expansion of a platform.

Embodiment
A kind of server dynamic capacity-expanding system, as shown in Figure 1, comprises load equalizer 110 and management server 120, and load equalizer 110 is for connecting storage server 200, and management server 120 and load equalizer 110 communicate to connect.
Load equalizer 110, for carrying out load monitoring to storage server 200, sends dilatation request instruction to management server 120 when the load of storage server 200 exceedes preset value; And the dilatation address information that receiving management server 120 sends, and establish a communications link, by the load regulation of storage server 200 to dilatation server according to dilatation address information and dilatation server.Management server 120, for after receiving dilatation request instruction, sends dilatation address information to load equalizer 110.
Namely dilatation address information refers to IP (InternetProtocol, the Internet protocol) address of dilatation server, can store in advance.After storage server 200 excess load being detected, carry out dilatation process by newly-increased dilatation server, by the load regulation of excess load server to dilatation server to avoid server disk off-capacity.The quantity of storage server 200 can be 1 also can be multiple, and when the quantity of storage server 200 is multiple, load equalizer 110 carries out load monitoring in real time to all storage servers 200.If detect that the load of storage server 200 exceedes preset value, then think that this storage server 200 is excess load server, load equalizer 110 sends dilatation request instruction to management server 120.After receiving the dilatation address information that management server 120 returns, carry equalizer 110 by the load regulation of excess load server to dilatation server.Be appreciated that after newly-increased dilatation server, dilatation server can be carried out load monitoring management as storage server 200 is unified by load equalizer 110 equally.
Load equalizer 110 by the load regulation of storage server 200 to dilatation server, can be specifically the storage server 200 of excess load is stored data batchmove a part to dilatation server, to reduce storage and the access burden of excess load server, thus realize dilatation.
Wherein in an embodiment, the load regulation of storage server 200 to dilatation server is by load equalizer 110, the access instruction of reception is sent to dilatation server, makes dilatation server obtain corresponding data content according to access instruction from storage server 200 and be back to load equalizer 110.Access instruction can be specifically transfer to load equalizer 110 from client or Internet Server, for conducting interviews to the data in storage server 200.Access instruction, after receiving access instruction, is transferred to dilatation server by load equalizer 110, and dilatation server obtains corresponding data content according to access instruction from storage server 200 and returns.
Namely be do not shift the data stored in excess load server in the present embodiment, just access instruction be transferred to dilatation server, carry out data access and extract operating to excess load server by dilatation server, share the load of excess load storage server.Data are not shifted in dilation process, the potential safety hazard that dilatation brings server data can be avoided further, improve expanding safe.
Wherein in an embodiment, as shown in Figure 2, server dynamic capacity-expanding system also comprises the client-server 130 communicated to connect with management server 120, and management server 120 is also for sending dilatation address information to client-server 130; Client-server 130 stores for sending data to dilatation server according to dilatation address information.
Client-server 130 can be specifically the equipment such as mobile terminal, desktop computer or notebook.The data that client-server 130 sends specifically can comprise the data of being carried out the operation generations such as web page access by the browser of client-server 130, and the data that user produces in the operation of client-server 130.Dilatation address information, after transmission dilatation address information to load equalizer 110, is also sent to client-server 130 by management server 120.Client-server 130 communicates to connect according to the dilatation address information and the dilatation server that receive, and the data of acquisition are sent to dilatation server store, and realizes the dynamic memory of asking corresponding resource.Realizing client when data store maps directly in the server of specifying, and carries out load balancing from client, reduces the load of load equalizer 110, improves dilatation reliability further.Be appreciated that client-server 130 also can be used for sending access instruction, the data stored in storage server 200 and dilatation server are conducted interviews operation.
Further, wherein in an embodiment, client-server 130 sends data to dilatation server according to dilatation address information and is stored as, establish a communications link according to dilatation address information and dilatation server, carry out hash operations from browser cooker acquisition data and obtain hashed value, distribute the data stored in memory of dilatation server according to hashed value.
After establishing a communications link with dilatation server, directly from browser cooker, obtain data.Carry out hash operations to the data obtained, according to the internal memory of the hashed value distribution dilatation server that computing obtains, the internal memory according to distributing stores data, improves data storing reliability.
Wherein in an embodiment, management server 120 after receiving dilatation request instruction, also for exporting dilatation information.Can be specifically by controlling warning light flicker, the modes such as control loudspeaker sounding or control display screen display presupposed information export dilatation information.After receiving dilatation request instruction, management server 120 also exports dilatation information, excess load phenomenon is there is to remind administrative staff's storage server 200, administrative staff also can carry out manual load regulation according to actual conditions to storage server 200, such as carry out load regulation between original multiple storage server 200, can further improve dilatation stability.
Above-mentioned server dynamic capacity-expanding system, after storage server excess load being detected, carries out dilatation process by newly-increased dilatation server, by the load regulation of excess load server to dilatation server to avoid server disk off-capacity.Can avoid when carrying out dilatation to server impacting the normal operation of website and user and access, also can reduce the restriction to server disk model, amount of capacity, effectively alleviate in dilation process the potential safety hazard that server data brings, make reliability high, and expansion method is simple, be convenient to platform dynamic expansion.
