Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention is described.
In existing quota management method, during providing virtualization services for user, when resource used by a user
When insufficient, the quota value that administrator provides a user is determining numerical value, which is not necessarily consistent with the demand of user
It closes.In order to solve this problem, the embodiment of the invention provides a kind of quota management method, device and electronic equipments, according to reality
Resource quota value is set dynamically in border business demand, improves the degree of conformity of quota and practical business demand.
Quota management method is provided for the embodiments of the invention first below to describe in detail.
Referring to Fig. 1, Fig. 1 is the flow chart of the quota management method of the embodiment of the present invention, is included the following steps：
S101 obtains the remaining usable levels and current dilatation threshold value of the resource for each resource in virtual machine,
When remaining usable levels are less than current dilatation threshold value, dilatation is carried out to the resource, increased quota value is dilatation quota value.Dilatation
Quota value is according to the current quota value of the resource of acquisition, virtual machine in the average growth rate of multiple preset time periods and pre-
If what the number of period determined, average growth rate is that the number of virtual machine in multiple preset time periods according to acquisition determines
's.
In the embodiment of the present invention, enterprise can provide virtualization to user (for example, employee in enterprise) by virtual machine
It services (such as desktop cloud), then, user can carry out handling official business by desktop cloud etc., virtual machine refers to the tool simulated by software
Have complete hardware system function, operate in complete computer in a completely isolated environment.Enterprise provides virtual
Resource in machine includes：CPU (Central Processing Unit, central processing unit), memory, disk etc..In general, enterprise
The size of the resource provided for user is limited, and in user's processing business, with the increase of portfolio, the resource of user can
Can be remaining insufficient, need the resource that administrator is user to carry out dilatation at this time.Since the embodiment of the present invention expands each resource
The method of appearance is similar, is illustrated by taking disk as an example herein.
Specifically, an initial value is usually arranged, if resource is not in user's use process when distributing resource for user
Foot carries out dilatation to the resource, after dilatation, if can also continue to carry out multiple dilatation with the increase of business demand.Separately
Outside, in dilatation, a threshold value also can be set, that is, when the remaining usable levels of the resource are less than the threshold value, triggering is expanded
Hold operation.In the embodiment of the present invention, the current quota value of the resource is the initial value being arranged, for example, disk is current
Quota value can be 800G.Current dilatation threshold value can be the value being arranged according to current quota value, certainly, current dilatation threshold value
It can also be the fixed value etc. of setting, it is not limited here.For example, current dilatation threshold value is the 1/10 of current quota value, i.e.,
80G.So, when the remaining usable levels of disk are 80G, dilatation can be carried out to disk.Increased quota value is dilatation
Quota value, dilatation quota value can be according to current quota value, virtual machines in the average growth rate of multiple preset time periods and pre-
If the number of period, determined by default calculation formula.Average growth rate refers to the average growth rate of virtual machine number, Ke Yigen
It is determined according to the number of virtual machine in multiple preset time periods.
S102 obtains user in multiple preset time periods to the actual use value of the resource, root by data collector
According to multiple actual use values, user is calculated to the increase in demand value of the resource, according to demand value added, remaining usable levels and current
Dilatation threshold value calculates dilatation threshold value next time.
In the embodiment of the present invention, multiple preset time periods can be the continuous period with same period, for example, can
To be 3 months in a season, each preset time period is 1 month, and the number of preset time period is 3.User is monthly
The actual use value of resource is usually different, user can be obtained respectively by data collector at this 3 months to disk
Actual use value.It is possible to according to three actual use values, January is calculated to 2 months users to the increase in demand value of disk,
And 2 months to user in March to the increase in demand value of disk, finally, calculating in first quarter, increase in demand of the user to disk
Value.Can value added, remaining usable levels and current dilatation threshold value according to demand, calculate dilatation threshold value next time, next time dilatation
Threshold value is threshold value when carrying out dilatation next time to disk.
S103, when the remaining usable levels in dilatation quota value are less than dilatation quota threshold value next time, according to dilatation
The number of quota value, average growth rate and preset time period determines the increased quota value of the institute of dilatation next time.
Specifically, remaining usable levels are less than should after obtaining dilatation quota value to disk progress dilatation by step S101
Next time when dilatation threshold value, dilatation next time is carried out to disk.Can according to dilatation quota value, average growth rate and it is default when
Between section number, pass through default calculation formula and determine the increased quota value of the institute of dilatation next time.This step calculates dilatation next time
Increased quota value in step S101 calculate dilatation quota value method can be similar, unlike, dilatation quota value
(i.e. first time dilatation increased quota value) is calculated based on current quota value (the quota value of initial setting up),
This step (i.e. the increased quota value of second of dilatation institute) is calculated based on dilatation quota value, and so on.Also
To say, when carrying out multiple dilatation, each dilatation increased quota value it is related to the quota value before dilatation.
The quota management method of the embodiment of the present invention obtains the residue of the resource for each resource in virtual machine
Usable levels and current dilatation threshold value carry out dilatation to the resource when remaining usable levels are less than current dilatation threshold value, increased
Quota value is dilatation quota value；Dilatation quota value is according to the current quota value of the resource of acquisition, virtual machine multiple
What the average growth rate of preset time period and the number of preset time period determined, average growth rate is according to the multiple default of acquisition
The number of virtual machine determines in period；User is obtained in multiple preset time periods to the resource by data collector
Actual use value calculates user to the increase in demand value of the resource according to multiple actual use values, according to demand value added, surplus
Remaining usable levels and current dilatation threshold value calculate dilatation threshold value next time；Remaining usable levels in dilatation quota value are less than next
When secondary dilatation quota threshold value, according to dilatation quota value, the number of average growth rate and preset time period, dilatation next time is determined
The increased quota value of institute.Compared with existing quota management method, the embodiment of the present invention can be directed to business demand, realize
Dynamic capacity-expanding improves the degree of conformity of quota Yu practical business demand.Meanwhile ensure that the reliability and stability of business, it drops
Low artificial O&M cost.
In a kind of implementation of the invention, in Fig. 1 embodiment S102, if the actual use value in j-th of period is
VMUj, the integer that j is 1 to n, according to formula：
User is obtained to the increase in demand value RMU of the resource,For weighting coefficient, the integer that i is 1 to n, n is default
The number of period.
In the embodiment of the present invention, the increase in demand value of two neighboring period is the actual use value of the latter period
Difference between the actual use value of previous period, and for multiple preset time periods, it can be according to above-mentioned formula meter
Calculate increase in demand value.For example, multiple preset time periods are 3 months in a season, then, increase in demand of the user to disk
Value be January to 2 months users to the increase in demand value of disk withProduct, in addition 2 months demands to user in March to disk
Value added withProduct.Wherein, weighting coefficient can be the value being arranged according to business demand, for example, the business in 2 months and March
To measure bigger, the portfolio in January is smaller,Weight can compareGreatly.
If remaining usable levels of the resource within j-th of period are ARCj, the integer that j is 1 to n, n is preset time period
Number, then remaining usable levels of the resourcebjFor ARCjWeight,
That is, for each preset time period, the remaining usable levels of the available preset time period resource, then, the resource is more
The remaining usable levels of a preset time period are the sum of the remaining usable levels of each preset time period resource.
If current dilatation threshold value is AQBnow, according to formula：
Obtain dilatation threshold value A QB next timenext,For adjustment factor.
According to above-mentioned formula as can be seen that if actual use value RMU is bigger, correspondingly, remaining usable levels ARC is smaller,
AQBnextNumerical value it is higher.It for adjustment factor, can be adjusted according to actual scene, usually less than 1/100.It needs
It is bright, work as AQBnowFor first time dilatation threshold value when, AQBnextFor the threshold value of second of dilatation；Work as AQBnowExpand for second
When the threshold value of appearance, AQBnextFor the threshold value of third time dilatation, and so on.I.e. when carrying out multiple dilatation, dilatation next time
Based on threshold value is the threshold value of a former dilatation.

QPBnext=QPBnow(1+CRC)n, determine the increased quota value QPB of the institute of dilatation next timenext。
In the embodiment of the present invention, when carrying out multiple dilatation, the increased quota value of the institute of dilatation next time can be primary in the past
Based on the increased quota value of dilatation institute.It is, QPBnowIt can indicate the increased quota value of preceding dilatation institute, accordingly
Ground, QPBnextIndicate the increased quota value of the institute of dilatation next time.Therefore, the dilatation quota for first time dilatation, in S101
Value is equal to current quota value and (1+CRC)nProduct.In general, (1+CRC)nValue be not more than 2, that is, adjacent dilatation twice
The increased quota value of institute will not be double.
