Detailed Description
In order to provide a better understanding of the present application, those skilled in the art will now make further details of the present application with reference to the drawings and detailed description. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
The core of the application is to provide a bandwidth resource allocation method, a device, equipment and a readable storage medium of a storage system, which can ensure that on one hand, a logic volume with large demand can be allocated to bandwidth resources not lower than a preset proportion, and on the other hand, idle bandwidth resources of a logic volume with smaller demand or no demand are allocated to a logic volume with actual demand, so that the system bandwidth utilization rate is improved as much as possible, and the waste of the system bandwidth resources is avoided.
In the following, an embodiment of a bandwidth resource allocation method of a storage system provided in the present application is described, with reference to fig. 1, where the embodiment includes:
s11, setting corresponding preset proportion for each logic volume of the storage system;
s12, determining bandwidth resources of preset proportion which are preset to be distributed to each logic volume according to the preset proportion and available bandwidth resources of the storage system in unit time;
s13, when bandwidth resources are allocated to the logic volume of the bandwidth resources to be occupied, judging whether the bandwidth resources with preset proportion meet the requirements of the logic volume; if yes, entering S14, otherwise entering S15;
s14, distributing bandwidth resources with preset proportion for the logic volume;
s15, distributing bandwidth resources of a preset proportion and bandwidth resources of a target logic volume to the logic volume to meet the demands of the logic volume, wherein the target logic volume is a logic volume borrowed by the bandwidth resources of the logic volume within the past T unit times and/or a logic volume which does not occupy the bandwidth resources for the longest time within the past T unit times.
The present embodiment abstracts bandwidth resource allocation, and considers that a storage system can only provide a certain amount of bandwidth resources in a unit time, and allocates bandwidth resources in a unit time for a logical volume each time. The method comprises the steps of firstly setting preset proportion (one-to-one correspondence between the logic volumes and the preset proportion) for each logic volume of a storage system according to experience, then determining available bandwidth resources of the storage system in unit time, and further determining bandwidth resources of the preset proportion which are expected to be allocated to each logic volume, wherein the bandwidth resources are bandwidth resources which can be occupied by the logic volume in unit time. It should be noted that here, only the allocation is to be made, and the bandwidth resources are not actually allocated to the logical volumes.
When the bandwidth resources are really allocated, firstly determining a logic volume of the bandwidth resources to be occupied, then determining the bandwidth resources with preset proportion corresponding to the logic volume and the requirements of the logic volume, judging whether the bandwidth resources with preset proportion meet the requirements of the logic volume, and if so, allocating the bandwidth resources with preset proportion to the logic volume; if the bandwidth resource is not satisfied, bandwidth resources of the target logical volume are allocated to the logical volume in addition to the bandwidth resources of the preset proportion to the logical volume so as to satisfy the requirement of the logical volume. In order to ensure the maximization of the utilization rate of the bandwidth resource, the target logical volume in this embodiment is specifically: the logical volumes that borrowed the logical tape bandwidth resources in the past T units of time and/or the logical volumes that did not occupy the bandwidth resources for the longest time in the past T units of time. The value of T can be set or adjusted according to the actual requirement, which is not limited in this embodiment.
Therefore, the embodiment introduces the concepts of bandwidth resource borrowing, bandwidth resource returning and borrowing expiration. The borrowing of bandwidth resources refers to that the embodiment allows the logic volume to borrow bandwidth resources of other logic volumes when the self requirements are not satisfied; the returning of the bandwidth resource refers to returning the bandwidth resource to the borrowed party which cannot meet the requirement, and it is worth mentioning that the bandwidth resource returned here is not the same bandwidth resource as the bandwidth resource which is borrowed before because the bandwidth resource has a time attribute; the expiration of borrowing refers to that once the borrowing relation exceeds T unit time, the borrowing record is subjected to sales, and the borrowing relation is considered to be absent, so that even if the demand of a borrowed party is not satisfied, bandwidth resources cannot be preferentially acquired from the borrowed party.
As a specific implementation, a borrowing record may be generated when bandwidth resource borrowing occurs; when the bandwidth resource returns, the borrowing record is subjected to sales; and when the existence time of the borrowed record exceeds T unit time, the borrowed record is also subjected to sales.
In this embodiment, only the logical volume occupies the bandwidth resource of the storage system, and in practice, the resource allocation logic of this embodiment may be further applied to other scenarios, such as the logical volume occupies the IOPS (Input/Output Operations Per Second, number of output/output operations per second) resource of the storage system, the object read/write occupies the bandwidth resource of the storage system, and the object read/write occupies the IOPS resource of the storage system.
According to the bandwidth resource allocation method of the storage system, the bandwidth resources of the storage system are effectively allocated among the plurality of logic volumes, firstly, the corresponding preset proportion is set for each logic volume, when the bandwidth resources are allocated, if the requirements of the logic volumes are large, the logic volumes are guaranteed to obtain the bandwidth resources not lower than the preset proportion no matter the system is busy or idle, otherwise, if the requirements of the logic volumes are small or no, the idle bandwidth resources are allocated to other logic volumes with requirements, and finally, the purpose of allocating the available bandwidth resources to the logic volumes with actual requirements as much as possible is achieved, the utilization rate of the bandwidth resources of the storage system can be improved obviously, and the idle of the bandwidth resources of the system is reduced.
The second embodiment of the bandwidth resource allocation method of the storage system provided by the present application is implemented based on the first embodiment, and is expanded to a certain extent based on the first embodiment.
Specifically, when allocating bandwidth resources to logical volumes, the second embodiment optimizes the allocation order of each logical volume.
Referring to fig. 2, the second embodiment specifically includes:
s201, setting corresponding preset proportion for each logic volume of a storage system;
s202, determining bandwidth resources of preset proportion which are preset to be distributed to each logic volume according to preset proportion and available bandwidth resources of a storage system in unit time;
s203, acquiring a target queue, and determining a logic volume positioned at the head of the target queue as a logic volume of the next bandwidth resource to be allocated;
the target queue is used for recording a logic volume of bandwidth resources to be occupied, and the arrangement sequence of the logic volume in the target queue is as follows: the logical volume borrowed by the bandwidth resource is in front, and the logical volume waiting to occupy the bandwidth resource is in back due to own demand.
If there are multiple logical volumes borrowed by bandwidth resources or multiple logical volumes waiting to occupy bandwidth resources due to their own needs, the order of arrangement of the logical volumes in the target queue is: the longer and the earlier the time the bandwidth resource was not occupied in the past T units of time.
S204, judging whether bandwidth resources with preset proportion meet the requirement of the logic volume or not; if yes, go to S205, otherwise go to S206;
s205, distributing bandwidth resources with preset proportion for the logic volume;
s206, distributing bandwidth resources with preset proportion for the logical volumes, and judging whether a first target logical volume exists, wherein the first target logical volume is a logical volume borrowed by the bandwidth resources of the logical volumes in the past T unit time; if so, go to S207, otherwise go to S209;
s207, further distributing bandwidth resources of a first target logical volume to the logical volume, and selling borrowed records between the logical volume and the first target logical volume;
specifically, if the number of the first target logical volumes is one, allocating bandwidth resources of the first target logical volumes to the logical volumes; and if the number of the first target logical volumes is a plurality of, sequentially selecting the first target logical volumes from the plurality of first target logical volumes according to the sequence from the early to the late of borrowing time, and distributing the bandwidth resources of the selected first target logical volumes to the logical volumes until the requirements of the logical volumes are met or the unselected first target logical volumes do not exist.
S208, judging whether the current requirement of the logical volume is met, if yes, not processing, otherwise, entering S209;
s209, judging whether a second target logical volume exists, wherein the second target logical volume is a logical volume which does not occupy bandwidth resources for the longest time in the past T unit time; if yes, entering S210, if not, not processing;
s210, further distributing bandwidth resources of a second target logical volume to the logical volume, and generating borrowed records between the logical volume and the second target logical volume;
s211, when the borrowing record is not sold for more than T unit time, the borrowing record is sold.
Based on the above-described second embodiment, the implementation procedure of this embodiment will be described below taking practical application as an example.
Assuming that the available bandwidth resource in unit time of the storage system is M, the available bandwidth resource needs to be occupied by N logical volumes according to a preset proportion, and M is to be allocated to each logical volume according to the preset proportion, the bandwidth resources expected to be occupied in unit time of each logical volume are M1, M2, … and mn respectively.
When the bandwidth resources are allocated to the logic volume, if the bandwidth resource quantity with the preset proportion can meet the requirement of the logic volume, only the bandwidth resource quantity with the preset proportion is allocated to the logic volume, and if the bandwidth resource quantity with the preset proportion cannot meet the requirement of the logic volume, the bandwidth resources of the target logic volume are allocated in addition to the bandwidth resources with the preset proportion. Specifically, bandwidth resources are preferentially obtained from the logical volumes borrowed by the logical bandwidth resources, when a plurality of logical volumes borrowed by the logical bandwidth resources exist, bandwidth resources are sequentially obtained from the logical volumes with borrowing relations at the earliest, and if the requirements of the logical volumes cannot be met, resources are borrowed from the logical volumes with bandwidth resources occupying the longest time within the past T unit times.
When the logical volume obtains the returned bandwidth resource from the borrower, the corresponding borrowing record needs to be billed, and the billing is started from the borrowing which occurs earliest in T unit time. When the bandwidth resource borrowing occurs, only the borrowing occurring in T unit time is calculated, and the borrowing exceeding T unit time is directly posted.
When a plurality of logic volumes wait for occupying bandwidth resources, logic volumes borrowed by other logic volumes are preferentially selected for allocation, if a plurality of logic volumes borrowed by bandwidth resources exist, logic volumes which do not occupy bandwidth for the longest time in the past T unit time are selected for allocation, and if no logic volumes borrowed by bandwidth resources exist, logic volumes which do not occupy bandwidth for the longest time in the past T unit time are selected for allocation.
Once the logic volume occupies the bandwidth resource, or the logic volume which has the borrowing relation borrows the bandwidth resource, the logic volume is calculated as the occupied bandwidth resource, and the time when the bandwidth resource occupies is the last occupied time point of the bandwidth resource.
It should be noted that, when the logic volume needs to occupy the bandwidth resource, the maximum amount of the bandwidth resource occupied by a single time is the product of the T unit times and the allocation amount of the unit time, and in this way, the situation that no new allocation scheduling process exists for a long time due to excessive bandwidth resource occupied by a single time is avoided.
