As shown in Figure 1, each IP disk is equivalent to one server, and multiple IP disks can form a server set in a symmetric manner. Among them, each server in the collection has an equivalent status, and can provide services separately without additional server assistance. In implementation, in order to avoid a large number of requests for concurrent access to the same server in the server collection, the management server acts as a load balancer, and uniformly distributes the requests sent by the client to the servers in the server set through a specific load balancing policy. The server that receives the request responds to the client independently.

detailed description

The technical solutions in the embodiments of the present application are clearly and completely described in the following with reference to the drawings in the embodiments of the present application. It is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present application without departing from the inventive scope are the scope of the present application.

It should be noted that the terms "first", "second" and the like in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or order. It is to be understood that the data so used may be interchanged where appropriate, so that the embodiments of the present application described herein can be implemented in a sequence other than those illustrated or described herein. In addition, the terms "comprises" and "comprises" and "the" and "the" are intended to cover a non-exclusive inclusion, for example, a process, method, system, product, or device that comprises a series of steps or units is not necessarily limited to Those steps or units may include other steps or units not explicitly listed or inherent to such processes, methods, products or devices.

The following briefly explains the related terms involved in this application as follows:

IP disk, as its name suggests, refers to a disk that uses the IP protocol (interconnect protocol between networks) interface instead of the traditional SCSI (Small Computer System Interface) standard protocol interface, and the traditional disk requires a small computer system. The interface communicates with the host to complete data read and write operations. It is a self-contained disk that can communicate with the host. Under the control of the host, the simpler and more general IP protocol and Ethernet technology are used to transfer data to and from the host, so that data read and write operations are performed spontaneously by key-value reading and writing. Compared with the performance bottleneck that is easily caused by the traditional SAS (Serial Attached SCSI)/SATA (Serial Advanced Technology Attachment) interface, the IP disk is connected to the host computer due to the IP interface. The interconnection is simpler, almost independent of distance, so there is no performance bottleneck, and the scalability of its storage system is greatly enhanced. At the same time, using IP disks, users no longer need to maintain a separate storage connection network, only need to maintain an IP network, which undoubtedly reduces the cost of the user.

The management server, also known as the metadata server, is primarily used to organize and manage spatial information.

The object server, also known as the object storage server, is mainly used to manage the online and offline tasks of the IP disk and some computing tasks.

A load balancer is a collection of servers in a symmetric manner by multiple servers. Each server has an equivalent status and can provide services separately without the assistance of other servers. The load balancer distributes externally sent requests evenly to a server in a symmetric structure through a load sharing technology, and the server receiving the request can independently request the corresponding client. The balanced loader is able to evenly distribute requests to the server set, thus providing a service that quickly acquires important data, and solves the problem of requesting a large number of concurrent accesses to the same server.

Example 1

The embodiment of the present application provides a method for allocating an internet protocol IP disk. It should be noted that the steps shown in the flowchart of the drawing may be performed in a computer system such as a set of computer executable instructions, and although The logical order is shown in the flowchart, but in some cases the steps shown or described may be performed in a different order than the ones described herein.

FIG. 2 is a flowchart of an optional method for allocating an internet protocol IP disk according to an embodiment of the present application. The method can be, but is not limited to, applied to a management server. As shown in FIG. 2, the method includes the following steps:

Step S202, receiving a data read/write request sent by the client;

Step S204, calculating an average time consumed by the currently selected (including but not limited to using a disk picking pointer to select) the IP disk to perform the most recent N data read and write operations, where N is a positive integer;

Step S206, determining whether the average time is less than the reference time, wherein the reference time is a time consumed by the preset disk to perform data read and write operations;

Step S208, in the case that it is determined that the average time is less than the reference time, the data read/write request is allocated to the currently selected IP disk (including but not limited to the disk picking pointer currently referred to).

In order to solve the problem that the IP disk cannot provide real-time information, the embodiment of the present application proposes a method for obtaining the pressure of the IP disk. Specifically, before the step S202 is performed, the fixed size of the I/O data in the data read and write operation may be set in advance, and the read/write operation of the fixed-size I/O data is performed each time repeatedly by the preset disk. The elapsed time, based on these times, calculates the average time taken by the preset disk to perform the operation of the fixed-size I/O data once, and uses the calculation result as the reference time. For example, the I/O data size is 1 MB in the data read/write operation in advance, and the average time consumed by the IP disk when processing 1 MB of I/O data is obtained through a large number of tests, and this time is used as the reference time. . In addition, for each IP disk, the management server records the start time and end time of the IP disk performing I/O data processing each time, and calculates the time taken to perform each I/O data processing. In order to avoid the contingency affecting the estimated IP disk pressure, the management server will further calculate the average time taken by the IP disk to perform the data read and write operations for the last N times (such as 5 times, which can be adjusted according to actual needs).

For example, when the client sends a data read/write request, the management server allocates a corresponding IP disk for the data read/write request. Specifically, after receiving the data read/write request sent by the client, the management server first checks the disk selection pointer. The currently referred IP disk calculates the average time it takes to perform the most recent N data read and write operations. For example, for the IP disk, if this is the sixth allocation request, the last 5 times of consumption can be calculated. The average time is compared with the reference time. If the average time is less than the reference time, it indicates that the current processing capacity of the IP disk is strong, so data read and write requests can be allocated to the IP disk for processing.

In an embodiment of the present application, in order to facilitate the allocation of IP disks, all IP disks in the load balancing system need to be sorted according to the order of the disk capacity, and a circular sort list of the IP disks is obtained, based on the The circular sorting list can achieve the purpose of distributing IP disks in turn. As shown in FIG. 3, for example, at the beginning, the disk picking pointer can be pointed to the linked list header, and each time an IP disk is selected, the pointer will be sequentially moved in the order of the IP disk's circular sorting list until it is returned to the linked list header. After a round of distribution, this cycle reciprocates to realize the rotation of the IP disk. purpose.

With the embodiment of the present application, the method of comparing the average time consumed by the IP disk to perform the most recent N data read and write operations and the reference time is achieved, and the management server is obtained when the IP disk cannot provide real-time information to the management server. Actively calculate the average time taken by the IP disk to perform the last N data read and write operations to determine whether to allocate data read and write requests to the IP disk, thereby achieving the technical effect of improving the load balancing effect of the management server, thereby solving In the related art, since the IP disk has limited processing capability and cannot provide real-time information to the management server, it is impossible to formulate a reasonable load balancing policy, which ultimately leads to a technical problem that the load balancing effect of the management server is not good.

Optionally, in the case that it is determined that the average time is not less than the reference time, the foregoing method further includes:

S2: Determine whether the read/write status of the IP disk is idle.

Optionally, the S2 is implemented by the following process to determine whether the number of times the data read/write request is allocated is 0. When the number of data read/write requests allocated to the IP disk is 0, the IP disk is idle, and the data of the IP disk is read. When the number of write request allocations is not 0, the read and write status of the IP disk is not idle, that is, it is busy.

S4. When it is determined that the read/write status of the IP disk is in an idle state (for example, the number of data read/write requests is 0), the data read/write request is allocated to the currently selected (including but not limited to the disk selection pointer currently referred to ) of the IP disk.

That is, if the average time is not less than the reference time, it indicates that the current processing capability of the IP disk is not very strong, and the IP disk may have the ability to respond to data read and write requests, or may not be able to respond to data read and write requests. In order to confirm whether it has the ability to respond to data read and write requests, in order to develop a more reasonable load balancing strategy, it is necessary to further determine the number of data read/write requests allocated by the disk selection pointer currently pointed to by the disk selection pointer. 0. If it is 0, it indicates that the IP disk is currently idle and can respond to data read and write requests. At this time, data read and write requests can be allocated to the IP disk.

It should be noted that, in order to monitor the status of each IP disk, the management server adds 1 to the allocation count of the IP disk each time the IP disk is allocated, and the IP disk reads and writes the IP disk every time the IP disk completes the data read and write operations. The corresponding allocation count is decremented by 1, so when the allocation count corresponding to an IP disk is 0, the number of data read/write requests allocated to the IP disk will be 0; otherwise, the IP disk The number of data read and write requests will not be 0.

In other embodiments of the present application, the management server may also determine whether the current state of the IP disk is idle or available by other means such as data traffic through the read/write interface.

Optionally, in the case that it is determined that the number of data read/write requests allocated by the IP disk is 0, and the data read/write request is allocated to the currently selected IP disk (including but not limited to the disk picking pointer currently referred to), The above methods also include:

S6: Clear the related record of the average time consumed by the IP disk to perform the last N data read and write operations.

Based on the above embodiments, the data read/write processing capability of the IP disk whose number of data read/write requests is 0 can actually satisfy the current data read and write request. In this case, the IP disk is allocated according to the actual situation. The upper is the number of data read and write requests allocated by the IP disk, not the average time it takes to perform the most recent N data read and write operations. That is, at this time, the IP disk can be allocated according to the former to obtain a better load balancing effect. Therefore, before the data read/write request is allocated to the IP disk currently pointed by the disk selection pointer, the IP disk is cleared for the last N times (for example, 5 times). The average time consumed by data read and write operations can prevent the management server from using the average time in the subsequent load balancing process, thus affecting the load balancing effect.

Optionally, in the case that it is determined that the read/write status of the IP disk is not in an idle state (for example, the number of times the data read/write request is not allocated is 0), the method further includes:

S8, select (including but not limited to, make the disk pick pointer point to the next IP disk to select) the next IP disk;

S10. Calculate an average time taken by the selected IP disk (including but not limited to the disk picking pointer) to perform the last N data read and write operations;

S12, determining whether the average time is less than a reference time;

S14. If it is determined that the average time is less than the reference time, the data read/write request is allocated to the selected IP disk (including but not limited to the disk picking pointer).

Since the number of data read/write requests allocated by the IP disk is not 0, it indicates that it is in a busy working state, and its current data processing capability is difficult to respond to data read and write requests sent by the client, and thus The data read and write request can be assigned to the IP disk currently referred to by the disk pick pointer. In this case, it is necessary to have the disk pick pointer point to the next IP disk and execute S10, S12, S14. S10, S12, and S14 are the same as steps S204, S206, and S208, and are not described here.

The next IP disk in the above step may be the next IP disk in the IP disk sequence table stored in the database, and the ordering may be pre-arranged, or may be calculated according to a preset rule or algorithm in step S8. of.

Optionally, before calculating an average time taken by the currently selected IP disk to perform the last N data read and write operations, the method further includes:

S16, determining that the IP disk is the Mth allocated data read/write request;

S18: Determine whether M is greater than N, where M is a positive integer, and if it is determined that M is greater than N, perform the step of calculating an average time consumed by the currently selected IP disk to perform the last N data read and write operations.

Optionally, in the case that it is determined that M is not greater than N, the foregoing method further includes:

S20. Directly allocate the data read/write request to the currently selected IP disk.

In order to improve work efficiency and prevent errors in calculating the average time, before calculating the average time, it can be determined that the IP disk is currently the first time to be allocated data read and write requests, for example, if the load balancing policy requires calculation of the average time of the last 5 times, The IP disk is currently assigned a data read/write request any one of the 1-4 times, and the data read/write request can be directly allocated to the IP disk. Otherwise, the disk selection policy in the above embodiment is required to allocate the corresponding disk. , will not repeat them here.
