Cloud database is increasingly known, and common are Kingsoft cloud etc., and people can pass through cloud management console The cloud database service for creating oneself usually first needs user to specify the appearance for starting cloud database when creating cloud database The specification of device, such as can take specified containers memory size as 1G, disk size 10G.Then it is in setting cloud database information After the information such as cloud database account, password, example number, the information set can be sent to service by confirming button Device.
Server can select an object according to the containers size that user specifies first after the information for receiving user's transmission Host is managed, container is then created on physical host, finally starts cloud database in a reservoir to realize cloud database service.So And in existing cloud database service, when the containers size specified according to user selects physical host be it is randomly selected, i.e., One is randomly choosed in the physical host that remaining storage resource is capable of storage container, random selection management is simple, without additional Code development quantity, but prolonged random selection can cause every physical host residue storage resource rate to differ greatly, can The case where certain physical hosts capable of being caused premature in saturation state, and if physical host is in saturation state meeting for a long time The working performance of the physical host is influenced, user experience is reduced.
The embodiment of the present invention selects in view of the above-mentioned problems, when selecting physical host to create the container of the specified specification of user Remaining storage resource rate is not less than the physical host of default first storage resource threshold value, wherein remaining storage resource rate, that is, physics master Machine residue storage resource and the ratio of total storage resource can subtract the difference obtained with storage resource by total storage resource Divided by total storage resource is calculated.For example, preset first storage resource threshold value can first be set as 70%, search whether There are the physical hosts that remaining storage resource rate is not less than 70%, and if so, showing that the physical host residue found stores It is high that resource utilization compares other physical host residue storage resources rates in resource pool, if there is no then can be by the first storage resource Threshold value is reduced to 60% and continues to search, until when the first storage resource threshold value is reduced to 30%, still without qualified Physical host, then it is assumed that the remaining storage resource rate of the physical host corresponding to mark in resource pool is not much different, then searches It is less than 5% physical host with the presence or absence of remaining storage resource rate, and if so, complete selection, if there is no then increasing the Two storage resource threshold values are 10%, and what is continued to search for whether there is qualified physical host, if otherwise continuing growing the Two storage resource threshold values search the physical host that remaining storage resource rate is less than default second storage resource threshold value up to 30%.
The embodiment of the present invention can choose the physics master that remaining storage resource rate is not less than default first storage resource threshold value Machine, also, during actual selection qualified physical host, presetting the first storage resource threshold value can be as needed Dynamic regulation is carried out, can ensure that the remaining storage resource rate for the physical host that final choice goes out is to be in money based on said program A higher level of all physical host residue storage resource rates in the pond of source, or even in some cases, higher residue Storage resource rate can ensure that the remaining storage resource rate for the physical host that final choice goes out is deposited higher than other physical host residues Store up resource utilization.The mode of the high physical host of the preferential remaining storage resource rate of selection in this way, can be with each physics master of efficient balance Machine residue storage resource rate, when the remaining storage resource rate of physical host in resource pool is below default first storage resource threshold value When, then dynamic select residue storage resource rate is less than the physical host of default second storage resource threshold value, can preferentially select to remain Balance stores up the low physical host of resource utilization, has preferentially utilized the few physical host of remaining storage resource broken to reduce storage resource Piece.
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other Embodiment shall fall within the protection scope of the present invention.
Referring to Fig.1, a kind of flow chart of physical host selection method provided in an embodiment of the present invention, this method tool are shown Body includes the following steps：
S110 receives container request to create, and the container request to create includes containers size.
Container technique is a kind of server resource sharing mode being widely recognized as by everybody, and container technique can be in on-demand structure It builds in the process of container technique operation system example and provides great flexibility for system manager, while can be at same The virtual machine instance quantity compared to twice before is created on server, therefore container technique will reduce system and always put into.
When user creates cloud database by client cloud management console, it usually needs first specify for starting cloud data The specification of the container in library, the i.e. size of the memory of specified containers and disk.The memory size of specific container can have 512M, 1G, 2G, 4G etc. are selected for user, and disk size can have 10G, 30G, 50G, 100G etc. to be selected for user, simultaneously to this present invention It does not limit.Containers size is can be increased during user's use, in this way when a certain user starts in use When specified containers size is not enough, increase-volume can be carried out according to self-demand.
User can wish to pass through cloud according to the demand of oneself come the specification of specified containers, such as user in a particular application Database purchase is mainly used to store video, the data such as picture, then its container that a disk can be specified big, such as memory 512M, disk 100G；And user wishes that when running some program codes, software, then one can be specified by cloud database The big container of memory, such as memory 2G, disk 10G.This present invention is not limited.
The embodiment of the present invention can also provide different containers sizes, such as high-grade user ratio for different users The containers size that the user of inferior grade can select is big, the container that the high user of the liveness user lower than liveness can select Specification is big, is not limited to this present invention.
The embodiment of the present invention can while meeting the needs of different users by providing the container of different size to the user It is more reasonably utilized storage resource, is reduced after a certain user specifies the container of one big specification and is not often used but and cause The case where storage resource wastes.
S120 selects remaining storage resource to be more than the physical host of the containers size, and by the mark of the physical host Know in storage to resource pool.
After server receives the containers size that user specifies, remaining storage resource is selected first according to containers size It is the physical host that remaining storage resource can create container more than the physical host of containers size, then by the physical host To in resource pool, resource pool is more than the same of the mark of the physical host of containers size in the remaining storage resource of record for mark storage When, each physical host storage resource service condition can also be recorded further to select qualified physical host.
In in a kind of realization method, server can be that each physical host distribute different marks, and resource pool is remaining Storage resource is more than the set that the physical host of containers size to be created identifies, and can be stored in service in the form of a list In device, the case where can also recording each physical host residue storage resource rate, may include total storage of each physical host Resource size and the size for having used storage resource.For example, wherein a certain physical host storage resource utilization power can record For：Physical host is identified as 001, and total storage resource 1000G, remaining storage resource 850G, remaining storage resource rate are 85%.Base Enable to server that can quickly understand each physics master in resource pool during subsequent selection physical host in this The storage resource service condition of machine, accelerates the selection course of physical host.
S130 selects in the physical host corresponding to mark in the resource pool remaining storage resource rate not less than pre- If the physical host of the first storage resource threshold value.
Storage resource threshold value refers to the ratio of pre-set remaining storage resource and physical host total resources.Such as certain object The total storage resource for managing host is 200G, and remaining storage resource is 180G, and remaining storage resource rate is 90%.When the first of setting When storage resource threshold value is 70%, then the physical host residue storage resource rate is 90% in subsequent selection course, greatly In 70%, then show that the physical host meets the condition of setting.
Understandable is that total storage resource of each physical host in resource pool is different, and the present invention passes through setting the One storage resource threshold value, even when total storage resource of each physical host corresponding to mark in resource pool is different, but It is that the remaining storage resource rate of each physical host changes between 0%-100%, by the way that phase is arranged for physical host With the first storage resource threshold value selected with this, avoid and selected only by the size of remaining storage resource When, in the case of there is the physical host residue storage resource selected more than other physical hosts, and the physical host is surplus Balance stores up the resource utilization problem low compared to other physical hosts, that is, the physical host selected is more compared to other physical hosts Close to saturation state, i.e., the ratio for accounting for total storage resource with storage resource is more nearly 100%.
It is now illustrated for convenience of understanding, the mark in resource pool is corresponding with two physical hosts, wherein No.1 object Reason host residue storage resource is 70G, and total storage resource is 100G；No. two physical host residue storage resources are 100G, are always deposited Storage resource is 500G, can select No. two physical hosts if the physical host more than the remaining storage resource of selection, but the physics Host residue storage resource rate is 20%, although and the remaining storage resource of No.1 physical host is 70G few compared to 100G, one Number physical host residue storage resource rate is 70%, it is clear that No. two physical hosts compared to the more adjunction of No.1 physical host Nearly saturation state, if that container can be then created to the low physical host of remaining storage resource rate by No. two physical hosts of selection On, it can not achieve the purpose that the remaining storage resource rate between balanced each physical host.
In a kind of realization method, the first storage resource threshold value can select qualified physical host from resource pool During dynamic regulation.Preset first storage resource threshold value can first be set as 70%, search whether there is remaining storage Resource utilization is not less than 70% physical host, and if so, showing the physical host residue storage resource rate found compared to money Other physical host residue storage resources rates are horizontal high in the pond of source, if there is no can then reduce the first storage resource threshold value Continue to search for 60%, and so on until find qualified physical host.
In above-mentioned search procedure, the physical host that remaining storage resource rate is not less than default first storage resource threshold value can Can only one, it is stored then the remaining storage resource rate for the physical host that final choice goes out then is higher than other physical host residues Resource utilization.
In a kind of realization method, default first storage resource threshold value can also be not less than select remaining storage resource rate Physical host after, continue to select the remaining highest physical host of storage resource rate in qualified physical host.
In a kind of realization method, in the case of no qualified physical host, it can also subtract in search procedure Few residue storage resource rate reduces amplitude, for example, only reduce 1% every time, makes physical host that final choice goes out with this Remaining storage resource rate is then higher than the remaining storage resource rate of other physical hosts.
Based on said program, then show the physical host residue storage resource after selecting qualified physical host One higher level of rate remaining storage resource rate of all physical hosts in resource pool, it is in some cases, higher Remaining storage resource rate can ensure that the remaining storage resource rate for the physical host that final choice goes out is surplus higher than other physical hosts Balance stores up resource utilization.The mode of the high physical host of the preferential remaining storage resource rate of selection in this way, can be with each object of efficient balance Manage host residue storage resource rate.
The first storage resource threshold value is preset in a kind of realization method can also be by counting corresponding to the mark in resource pool Physical host average residual storage resource rate come the value that determines, for example, the physical host corresponding to mark in resource pool Average residual storage resource rate be 50%, then can set the first storage resource threshold value be 60%, i.e., setting one be more than The value of average residual storage resource rate is provided with this to select remaining storage in the physical host corresponding to the mark in resource pool Source rate is compared to the horizontal high physical host of other physical hosts.
In one embodiment of the present invention, in the case that S130 is judged as NO, i.e., corresponding to the mark in resource pool The remaining storage resource rate of physical host when being less than default first storage resource threshold value, then execute S140：
Remaining storage resource rate is selected to be less than default second in the physical host corresponding to mark in the resource pool The physical host of storage resource threshold value.
In actual application, when the remaining storage resource of certain physical host is not enough to create the container of big specification (such as disk 1000G) then the physical host may be idle and cause storage resource fragmentation.
In a kind of realization method, the minimum value of a first storage resource threshold value can be set, i.e., in the mistake of dynamic regulation There are no qualified physical host when the first storage resource threshold value is reduced to the minimum value of setting in journey, then resource pool is judged In mark corresponding to the remaining storage resource rate of physical host be less than default first storage resource threshold value, correspondingly in resource Remaining storage resource rate is selected to be less than the physics of default second storage resource threshold value in the physical host corresponding to mark in pond Host.Wherein, the second storage resource threshold value can also be moved during selecting qualified physical host from resource pool State is adjusted.For example, it is 5% that the second storage resource threshold value, which can first be arranged, the physics master that remaining storage resource rate is less than 5% is searched Machine.Based on this, the horizontal low physical host of physical host residue storage resource rate corresponding to the preferential mark selected in resource pool, It is preferential that the remaining storage resource rate of the physical host corresponding to mark in resource pool is less than default first storage resource threshold value The storage resource of the few physical host of remaining storage resource is utilized, prioritized resources are concentrated, and storage resource fragmentation is prevented.
For convenience of understanding, the object that a preferred embodiment meets above-mentioned selection default storage resource threshold value is set forth below The process of reason host is described：
Container request to create is received, the container request to create includes containers size.
User is the specification for needing first specified containers creating cloud database by cloud management platform, and containers size can be Memory 1G, disk 10G.After user has specified the specification of container, containers size information is sent to server.
The remaining storage resource of selection is more than the physical host of the containers size, and the mark of the physical host is put into In resource pool.
After server receives the containers size information of user's transmission, remaining storage resource rate is selected first and is more than institute Containers size is stated, i.e., remaining storage resource can create the physical host of container, then by the mark for the physical host selected It is put into resource pool and records the storage resource utilization power of each physical host.
Select remaining storage resource rate not less than default the in the physical host corresponding to mark in the resource pool The physical host of one storage resource threshold value.
The initial value of server settings the first storage resource threshold value is 60%, searches whether that there are residues to deposit in resource pool Store up resource utilization be not less than 60% physical host, if there is complete select, if there is no then, reduce the first storage resource threshold Value be 50%, search whether that there are qualified physical hosts, continue if not reduce the first storage resource threshold value until 30%, search whether there is physics master of the remaining storage resource rate not less than the default first storage resource threshold value after changing successively Machine.
The remaining storage resource rate of physical host corresponding to the mark in resource pool is below default first storage money Remaining storage resource rate is selected to be less than default second when the threshold value of source, in the physical host corresponding to mark in the resource pool The physical host of storage resource threshold value.
If preset first storage resource threshold value is reduced to 30%, still without qualified physical host, then recognize It is not much different for the remaining storage resource rate of the physical host corresponding to the mark in resource pool, then selects remaining storage resource rate Less than the physical host of default second storage resource threshold value.
Second storage resource threshold value of server settings is 5%, searches whether there is remaining storage resource in resource pool Rate is less than 5% physical host, and if so, completing selection, is if there is no the second storage resource threshold value is then increased 10%, what is continued to search for whether there is qualified physical host, if it is straight otherwise to continue growing the second storage resource threshold value To 30%, the physical host that remaining storage resource rate is less than default second storage resource threshold value is searched.
The embodiment of the present invention is when selecting physical host to create container, the physical host corresponding to mark in resource pool In, dynamic select residue storage resource rate is not less than the physical host of default first storage resource threshold value, is based on this skill of the present invention The remaining storage resource rate for the physical host that art scheme final choice goes out is the physics master corresponding to the mark that is in resource pool One higher level of machine residue storage resource rate.The remaining high physical host of storage resource rate of selection preferential in this way Mode, can be with each physical host residue storage resource rate of efficient balance, and works as and identify corresponding physical host in resource pool Remaining storage resource rate when being below default first storage resource threshold value, then dynamic select residue storage resource rate is less than default The physical host of second storage resource threshold value, the physical host that can preferentially select remaining storage resource rate low, preferentially will be remaining The few physical host of storage resource has been utilized to reduce storage resource fragmentation.
In a kind of realization method of the embodiment of the present invention, physical host selection method of the present invention can also include：
According to the performance parameter of each physical host selected a weights are distributed for the physical host each selected.
Weights are an opposite concepts, and for a certain performance parameter, the weights of a certain performance parameter refer to the property Relative importance of the energy parameter in the overall evaluation, in practical applications for the computer of different purposes, to different portions The performance indicator of part requires different.Such as：For as the computer based on scientific algorithm, to the arithmetic speed of host It is required that very high；For the computer based on being handled as large database, to the memory size, access speed and external memory of host The read or write speed of reservoir is more demanding；For the computer as network transmission, then require have very high I/O speed, therefore answer When the I/O buses and corresponding I/O interfaces for having high speed.Weights are that weight is separated from several performance parameters, can be directed to The height of the performance parameter of each physical host performance distributes weights for each physical host.The performance of physical host performance is joined Number is higher to give the weights matched higher.
In a kind of realization method, in all users that cloud database service can have been used by statistics in the present invention Usage behavior determines the weights of a certain performance parameter.For example, running program by cloud database when counting in all users Code, application software user compared with using other functions user it is more when, then show user to physical host arithmetic speed demand Relative to other performance parameters height, it is determined that the weights of physical host arithmetic speed performance parameter are higher than other performance parameters Weights；And when the user stored using cloud database in all users counted is more compared with using the user of other functions When, then show user to physical host storage resource demands relative to other performance parameters height, it is determined that physical host storage money The weights of source volumetric properties parameter are higher than the weights of other performance parameters.
Wherein performance parameter may include：Physical host arithmetic speed, physical host memory size, network interface card communication speed.
Physical host arithmetic speed refers to the instruction number that physical host can execute each second, generally with can execute hundred per second Ten thousand instruct numbers to weigh, and unit is million instructions per second.The principal element for influencing physical host arithmetic speed is centre Manage the storage cycle of the dominant frequency and memory of device.
The storage resource capacity of physical host refers to the size of physical host hard-disk capacity.The capacity of hard disk with Mbytes (MB) or gigabytes (GB) is unit, 1GB=1024MB, 1TB=1024GB.The capacity performance index of hard disk further includes the list of hard disk Dish capacity.So-called single dish capacity refers to the capacity of hard disk individual discs, and single dish capacity is bigger, and unit cost is lower, average access Time is also shorter.
Network interface card communication speed refers to the ability of network interface card reception each second or transmission data, and unit is Mbps (megabit per second).Net The ability of higher reception each second of card communication speed or transmission data is stronger.
Select the physical host of the maximum weight.
The the weights of the physical host of selection the big, indicates that the comprehensive performance of the physical host of selection is better, is stored in residue The maximum physical host of preoption value among the qualified physical host of resource utilization, so as to by high performance physics Chiller priority distributes to user, improves user experience.
In a kind of realization method physics can also be distributed for each user according to the difference for the containers size that user specifies Host then illustrates that the user is not high to cloud database service demand, then when some user specifies the container of a minimum gauge The physical host of weights minimum can be distributed to the user；Accordingly when some user specifies the container of a maximum specification When the physical host of maximum weight can be distributed to the user.Based on this, the embodiment of the present invention can be directed to the demand of user Difference distribute the physical host of different weights, the physical host of high weight can preferentially distribute to the big user of demand.
With reference to Fig. 2, show in the embodiment of the present invention to be that the physical host of each selection distributes the step flow of a weights Figure, the step can specifically include：
S21, the significance level of every performance parameter of the physical host performance more each selected.
Significance level can be understood as user in practical applications, can be by obtaining institute to the degree of dependence of a certain performance There is user's historical data to determine, can specifically see user often with which parameter, which is just important.Such as it is all It is more compared with using the user of other functions using operation program in cloud database in user, then illustrate the performance of physical host performance The significance level of physical host arithmetic speed this parameter in parameter is higher than the significance level of other performance parameters.It is all When carrying out the behavior of the resources such as storage video, picture in user using cloud database compared with utilizing the user of other functions more, then say The significance level of physical host storage resource capacity this parameter in bright physical host performance parameter is joined higher than other performances Several significance levels.
S22 determines the significance level of the physical host each selected according to the significance level per performance parameter.
In a kind of embodiment, it is possible, firstly, to be every according to the size of each each performance parameter of the physical host selected Each performance parameter of physical host of a selection distributes the value of significance level.The value of performance parameter is most in the physical host of selection Big, significance level is set as maximum, then according to the value of the physical host performance parameter and maximum performance parameter of other selections Ratio, to determine the significance level of every performance parameter.For example, it is 1000G that storage resource capacity is maximum in physical host, It can determine that the significance level of the physical host storage resource capacity is 10, then the physical host of storage resource capacity 500G is deposited The significance level for storing up resource capacity is 5, and the significance level of the physical host storage resource capacity of storage resource capacity 100G is 1.
It is then possible to according to user using the actual use situation of physical host performance come the performance parameter for physical host Distribute a coefficient, user that certain performance parameter is actually used in all users is more at most that performance parameter distribution is Number is bigger, for example it is 1000 people to use the total number of users of cloud database service, counts and carries out operation program using cloud database The number of code be 500 people, using the resources such as cloud database purchase video, picture number be 300 people, using cloud database into The number of row network data transmission is 200 people, and the utilization rate ＞ of physical host arithmetic speed is then can be assumed that according to statistical result The utilization rate of the utilization rate ＞ network interface card communication speeds of physical host storage resource, can set the coefficient of physical host arithmetic speed It is 0.5；The coefficient of physical host storage resource is 0.3；The coefficient of network interface card communication speed is 0.2.
The calculation formula of the significance level of the last physical host each selected can be expressed as physical host arithmetic speed Significance level * 0.5+ physical host storage resources significance level * 0.3+ network interface card communication speeds network interface card communication speed weight Want degree * 0.2.
Said program avoids the performance parameter of the value of a certain item performance parameter of physical host higher than other physical hosts Value, but this performance parameter is not but that parameter that user is commonly used, and leads to the physical host distributed for user And the problem of user actually uses situation is not met.
S23, using the significance level of the physical host each selected, for the physical host distribution each selected One weights.
Higher the distributed weights of significance level of the physical host of selection are bigger.In a kind of realization method, for convenience The weights for calculating the physical host that the significance level of the physical host of each selection can be used as to each selection, to this present invention It does not limit.
Present invention determine that each select physical host weights the step of, consider each of the physical host of each selection The practical utilization power of performance parameter and each performance parameter user, to determine the physical host different performance each selected ginseng Several significance level and then distribute weights for the physical host each selected so that each of determine the physical host selected Weights are more in line with the use habit of user.

In the significance level of the first performance parameter in determining the performance parameter institute is removed higher than in the performance parameter When stating the significance level of other performance parameters other than first performance parameter, it is according to the parameter value of the first performance parameter then The physical host each selected distributes a weights.
The embodiment of the present invention can only consider a performance parameter to determine the physics master each selected to simplify operation The significance level of machine.For example, relatively utilizing it when counting the user in all users using the program of operation in cloud database His user of function is more, it is determined that the significance level of physical host arithmetic speed this parameter in performance parameter is higher than it The significance level of his performance parameter, can be using physical host arithmetic speed as first performance parameter based on this, then basis Physical host arithmetic speed determines the significance level of the physical host each selected, then further according to the physics master of each selection The importance of machine is that the physical host each selected distributes a weights.
In a kind of realization method, the present invention can also provide cloud database work(when user specifies the container of different size Energy options allows user's selection that cloud database is mainly used in storage resource and is also primarily used for the work(such as program code execution Can, based on this server can according to user itself select come for user distribute physical host.I.e. when user selects main use When storage resource, then for the user in physical host performance parameter physical host storage resource capacity important journey Degree is higher than other performance parameters, then server only can be selected each according to physical host storage resource capacity to determine The significance level of physical host, the then physical host further according to the significance level of each physical host selected each to select Distribute a weights.
And when user's selection is mainly used for program code execution, then the physical host performance parameter for the user The significance level of middle physical host arithmetic speed is higher than other performance parameters, then server can be transported only according to physical host Speed is calculated to determine the significance level of the physical host each selected, then further according to the important journey of the physical host of each selection Degree distributes a weights for the physical host each selected.Can be every according to the difference of user's self-demand based on this present invention A user simplifies physical host during distributing physical host and selects step.
