Specific embodiment
It should be appreciated that specific embodiment described herein is not intended to limit the present invention only to explain the present invention.
The present invention provides a kind of object memory interface load-balancing method based on cluster file system.
In one embodiment, the method is applied to one includes client, dns server, arbitration agencies and arbitrating server
In 100 cluster file system, during the arbitration agencies are arranged at each node of system and in the dns server, the side
Method is comprised the following steps：
S100 obtains each node load of system.
System load in the present embodiment refers to this enforcement such as network traffics, cpu load, EMS memory occupation, hard disk load
In example, arbitrating server 100 obtains the system load information that arbitration agencies are collected.
S200 is according to each node load computing system average load of the system.
After system load is obtained, the average load of each node load of further computing system.With net in the present embodiment
As a example by network flow, the network traffics of system each node are added and obtain total flow, then system is obtained divided by node number average
Network traffics.
S300 obtains node of the load more than system average load according to the system average load.
Further, node data of the load more than system average load is further obtained in the present embodiment.With network flow
As a example by amount, successively the network traffics of each node for obtaining are compared with the system average discharge for calculating gained, until obtaining
Node of whole flows more than system average discharge.
S400 is sent to server when the load is more than predetermined threshold value more than the load of the node of system average load
System call interception is asked.
Node in the present embodiment further by load more than system average load is compared with default threshold value, it is clear that
If system load is not up to default threshold value, system load is thrown away in controlled range, can't now affect making for system
With effect, it is then to send system call interception request to server when system load reaches default threshold value.Threshold value in the present embodiment
The limits value shoulding be during each node normal work of system, in general, is reserved as 1.2 times of system standard load, in this model
In enclosing, system still can normal work.
In order to further improve effect of optimization, in the present embodiment, preferably certain priority evaluation is given by each arbitration agencies,
1-10 is assessed as example, wherein 1 highest priority, during being adjusted to system, should preferentially meet high priority
Node loading demand.
The technical scheme of the present embodiment improves system load by corresponding adjustment is made to system for system load
Utilization rate, also plays the effect of equalizing system load.
In one embodiment, the type of the node is Web server, and step S400 is specially：
S410, when it is described load more than system average load node load be more than predetermined threshold value when, dynamic modification DNS
Record makes client access different Web servers.
The technical scheme of the present embodiment is directed to the access situation of Web service, in the present embodiment, by dynamic modification
DNS is recorded, and when certain Web server flowing of access is too high, modification DNS records are so that client is accessed with identical data
Other Web servers, with equalizing system load.
In another embodiment of the present invention, the type of the node is cluster file system node, step S400
Specially：
S420, when it is described load more than system average load node load be more than predetermined threshold value when, judgement need access
Whether the load of file place node is all more than default load；If so, S421 steps are then performed, if it is not, then performing S422 steps
Suddenly.
Access request is simultaneously transferred to the copy place node by S421, the interim copy of increase；
S422, node of the load not less than default load that access request is transferred to file place.
The technical scheme of the present embodiment is directed to cluster file system node, in the present embodiment, according to file destination
The load of place node is adjusted, if the load of whole nodes exceedes default load, increases temporary visit copy；If depositing
Certain node load not less than default load, then access request is transferred to into the node.The technical scheme of the present embodiment can be with
The load of efficient balance cluster file system node.
Based on above-described embodiment, the fourth embodiment of the inventive method proposed, after each node load of the acquisition system
Also include step：Obtain the type of node.
In the present embodiment, the type of system node is obtained first, and according to the type of system node targetedly to being
System is adjusted, and improves the adaptability of system.Used as a kind of improvement, the step can be holding after step S300
OK, specifically, if it is determined that the type of node is Web server, then the S410 steps are performed, if it is determined that the type of node
For cluster file system node, then the S420 steps and its subsequent step are performed.
It is in fiveth embodiment of the method for the present invention based on above-described embodiment, described to ask to server transmission system call interception
Also include step after asking：
Timing acquisition system load statistical data, and default tune is made to server according to the system load statistical data
It is whole.
By periodically obtaining system load statistical data in the present embodiment, system load model is generated, is done for server
Go out default adjustment.Specifically, can be set as primary system loading statistics were obtained per 10 days, obtaining system load statistics
After data, system load model, and the trend that analysis system load is increased or decreased are set up, for example, for cluster file system
System load after 12 points of node evening tends to low-level, and tends to high level in the load of late 7. -10 dot system, then can be actively
Adjustment system load, automatically generates some interim copies in late 7. -10 point, to tackle the high capacity of system, and late 12 points with
After delete interim copy.Combined with passive regulation by actively regulation in the present embodiment, further increased to system load
Portfolio effect, it helps save system resource.
Additionally, for achieving the above object, the present invention also provides a kind of object memory interface based on cluster file system and bears
Equalizing system, including client, dns server, arbitration agencies and arbitrating server 100 are carried, the arbitration agencies are arranged at and are
In each node of system and in the dns server, the arbitrating server 100 includes：
First acquisition module 10, for obtaining each node load of system.

In example, arbitrating server 100 obtains the system load information that arbitration agencies are collected.
Computing module 20, for according to each node load computing system average load of the system.
After system load is obtained, the average load of each node load of further computing system.With net in the present embodiment
As a example by network flow, the network traffics of system each node are added and obtain total flow, then system is obtained divided by node number average
Network traffics.
Second acquisition module 30, for obtaining section of the load more than system average load according to the system average load
Point.
Further, node data of the load more than system average load is further obtained in the present embodiment.With network flow
As a example by amount, successively the network traffics of each node for obtaining are compared with the system average discharge for calculating gained, until obtaining
Node of whole flows more than system average discharge.
Sending module 40, when the load for being more than the node of system average load when the load is more than predetermined threshold value,
System call interception request is sent to server.
Node in the present embodiment further by load more than system average load is compared with default threshold value, it is clear that
If system load is not up to default threshold value, system load is thrown away in controlled range, can't now affect making for system
With effect, it is then to send system call interception request to server when system load reaches default threshold value.Threshold value in the present embodiment
The limits value shoulding be during each node normal work of system, in general, is reserved as 1.2 times of system standard load, in this model
In enclosing, system still can normal work.
