Embodiment
For making the object, technical solutions and advantages of the present invention clearly understand, below in conjunction with embodiment also with reference to accompanying drawing, the present invention is described in more detail.Should be appreciated that, these describe just exemplary, and do not really want to limit the scope of the invention.In addition, in the following description, the description to known features and technology is eliminated, to avoid unnecessarily obscuring concept of the present invention.
Fig. 1 is the schematic flow sheet of the method that optimization hard disk of the present invention uses.
As shown in Figure 1, the method that optimization hard disk of the present invention uses,
Step S100, the space weights of real time record hard drive space.
In the use procedure of physical hard disk, the space weights of real time record hard drive space.Wherein, when user reads and writes hard drive space, value of being reordered by the space weights of this hard drive space, such as, add 1.User can according to actual needs, change arbitrarily this definite value; Such as the space weights of hard drive space are 3000 at present, definite value is 1, after user carries out read-write operation to this hard drive space, (read-write operation of trigger either spatial weights change can be the size, time or number of times etc. that read and write data, as read and write 500MB data after, space weights increase by 1, and after can also being 20 read-writes, space weights increase by 1, in certain the present invention, the change condition of trigger either spatial weights is not limited thereto), the space weights of this hard drive space are 3001.
Step S200, judges whether described space weights exceed space weights higher limit.
According to the record result of step S100, real-time judge space weights enough exceed space weights higher limit.Like this, just can according to being that the hard drive space exceeding space weights higher limit exchanges operation to judged result.
Step S300, when described space weights exceed described space weights higher limit, exchanges described hard drive space and space weights lower than the hard drive space of space weights lower limit.
When the judged result of step S200 is for exceeding space weights higher limit, described hard drive space and space weights are exchanged lower than the hard drive space of space weights lower limit.Such as, when the space weights of a certain hard drive space exceed space weights higher limit (as 10,000), find space weights and exchange lower than the hard drive space in space weights lower limit (such as 10).Wherein, space weights higher limit and space weights lower limit, can be arranged by User Defined.
When the judged result of step S200 is for being no more than space weights higher limit, continue the space weights of real time record hard drive space, whether real-time judge has the space weights of hard drive space to exceed space weights higher limit, then carry out exchanging of hard drive space.
Wherein, described in carry out exchanging operation time be when two hard drive spaces are not in active state, perform and exchange operation.Specifically, when two hard drive spaces are all in active state (being namely in data read and/or write state) or one of them hard drive space is in active state, now do not perform and exchange operation.Only have when two hard drive spaces are all in inactive state, now two hard drive spaces are exchanged.
Wherein, after hard drive space is exchanged, retain the former space weights of this hard drive space.Specifically, after exchanging operation to two hard drive spaces execution, its original space weights do not empty, and namely retain original space weights.Such as, accept above-mentioned example, the space weights 10,000 and 10 of two hard drive spaces after exchanging are retained.
Wherein, the rule change of hard drive space weights is: when user reads this hard drive space and/or writes, value of being reordered by the space weights of hard drive space.Specifically, when user reads a certain hard drive space and/or writes, value of being reordered by the space weights of hard drive space, such as, add 1.If this hard drive space is through exchanging, so when user reads this hard disk and/or writes, then the space weights of this hard drive space current obtain add definite value on the basis of original space weights after.
Wherein, when user applies for hard drive space, if described hard drive space is not assigned to user, then the space weights of described hard drive space are subtracted definite value.Specifically, when there being new user to apply for hard drive space, using if a certain hard drive space is not assigned to user, then the space weights of this hard drive space being subtracted definite value, such as 1.
By the above-mentioned method be optimized hard disk based on hard drive space weights, balance the frequency of utilization of hard disk in cloud computing system, extend the serviceable life of hard disk, reduce the maintenance times of hard disk, thus reduce maintenance cost.
Fig. 2 shows in an embodiment of the present invention and applies for that hard drive space optimizes the method flow diagram of hard disk use based on user.
In the present embodiment, based on user, optional employing applies for that hard drive space is optimized use to hard disk.
As shown in Figure 2, described method of applying for the use of hard drive space optimization hard disk based on user, it comprises:
Step S10, real time scan physical hard disk is to obtain the space weights of hard drive space.
In hard disk use procedure, in real time the space weights obtaining each hard drive space are scanned to physical hard disk.
Step S11, judges that whether described space weights are lower than space weights lower limit.
According to the scanning result of step S10, whether the space weights of the hard drive space that real-time judge scanning obtains are lower than space weights lower limit.
Space weights, when user applies for hard drive space, are preferentially distributed to user's use lower than the hard drive space of space weights lower limit by step S12.
Specifically, when user applies for hard drive space, the hard drive space preferentially space weights being less than space weights lower limit distributes to user's use.
In the present embodiment, apply for that the method that hard drive space optimization hard disk uses can independently perform based on user, preferably, also can be used as performing the method that hard disk is optimized based on hard drive space weights as a kind of supplementary.
Fig. 3 shows in an embodiment of the present invention based on distributing the hard drive space optimised method flow diagram that hard disk uses.
In the present embodiment, optional employing is optimized use based on distribution hard drive space size to hard disk.
As shown in Figure 3, the described method based on distribution hard drive space size, hard disk being optimized to use, it comprises:
When user applies for storage space, for user distributes a hard drive space, the memory space of described hard drive space is the fixed value preset; When the usage space of user exceedes the hard drive space that user has at present, by the data copy of user in other hard drive spaces being greater than described usage space.
A kind of preferred version more specifically:
Step S20, when user applies for hard drive space, the hard drive space of distributing the first pre-sizing uses to user.
In this step, when user applies for hard drive space, first the hard drive space of the pre-sizing of dynamic assignment first uses to user.Wherein, described hard drive space is continuous print hard drive space, because in cloud computing, hard disk, when calling, normally calls continuously.
Step S21, judges whether the usage space of user exceedes the hard drive space of the described first pre-sizing.
In the use procedure of described hard drive space, whether the usage space of real-time judge user exceedes the hard drive space of the described first pre-sizing.
Step S22, when the hard drive space of usage space pre-sizing more than first of user, by data copy in the hard drive space of the second pre-sizing.
When the usage space that the judged result of step S21 is user exceedes the hard drive space of the described first pre-sizing, Data Dynamic in the hard drive space of the first pre-sizing is copied in the hard drive space of the second pre-sizing, which increases the usage space of user writable data.Wherein, the hard drive space of the pre-sizing of the hard drive space < second of the first pre-sizing.
Step S23, judges whether usage space exceedes the hard drive space of the described second pre-sizing.
Same, in the use procedure of physical hard disk, whether the usage space of real-time judge user exceedes the hard drive space of the described second pre-sizing.
Step S24, when the hard drive space of usage space pre-sizing more than second of user, by data copy in the hard drive space of the 3rd pre-sizing.
When the usage space that the judged result of step S23 is user exceedes the hard drive space of the described second pre-sizing, the Data Dynamic in the hard drive space of the second pre-sizing is copied in the hard drive space of the described 3rd pre-sizing.Wherein, the hard drive space of the pre-sizing of hard drive space < the 3rd of the second pre-sizing.
In the present embodiment, independently can perform based on distributing the hard drive space optimised method that hard disk uses, preferably, also can be used as performing the method that hard disk is optimized based on hard drive space weights as a kind of supplementary.
Here is of the present invention one concrete example.
When user applies for hard drive space, such as 100G, first gives the hard drive space of the pre-sizing of user's dynamic assignment first, such as 10G continuous print hard drive space.Use in the process of this 10G continuous print hard drive space user, the usage space of real time record user, when the usage space of user is more than 10G, the Data Dynamic in 10G hard drive space is copied in the hard drive space of the second pre-sizing, such as 30G continuous print hard drive space.Same, use in the process of this 30G continuous print hard drive space user, the usage space of real time record user, when the usage space of user is more than 30G, Data Dynamic in 30G hard drive space is copied in the hard drive space of the 3rd pre-sizing, such as 60G continuous print hard drive space.The method is in order to avoid a continuous print hard drive space is read and write by short data frequently.
In the present invention, in the actual use procedure of physical hard disk, distribute the number of times of hard drive space size, because situation difference can be different.Such as, first time distributes the hard drive space of 50G, and when user's usage space exceeds the space of this 30G, the space distributing 100G uses to user, now, this space enough when, only carried out 2 sub-distribution of hard drive space.Again such as, first time distributes 20G hard drive space and uses to user, when user's usage space exceeds the space of this 20G, the space distributing 25G uses to user, now, when this space is not enough, proceed the 3rd sub-distribution or the 4th distribution, until this hard drive space meets the user demand of user, stop the distribution of hard drive space.
Fig. 4 shows in an embodiment of the present invention and repartitions based on the periodicity of hard disk the method flow diagram optimized hard disk and use.
In the present embodiment, optionally adopt the periodicity based on hard disk to repartition and use is optimized to hard disk.
As shown in Figure 4, the described periodicity based on hard disk repartitions method hard disk being optimized to use, and it comprises:
Step S30, the continuous access times of real time record hard drive space;
In the use procedure of physical hard disk, the continuous access times of real time record hard drive space.
Step S31, when the continuous frequency of utilization of the hard drive space of the first pre-sizing is more than the 3rd threshold value, upper once the physical space of hard disk is divided time, repartition according to the hard drive space of the second pre-sizing.Such as, when the continuous access times of the hard drive space of 1 10G are more than 100 times, when next time divides this physical hard disk, repartition according to the hard drive space of 30G.
Step S32, when the continuous frequency of utilization of the hard drive space of the second pre-sizing is more than the 4th threshold value, upper once the physical space of hard disk is divided time, repartition according to the hard drive space of the 3rd pre-sizing.Such as, accept above-mentioned example, when the continuous access times of the hard drive space of 30G are more than 10 times, when next time divides this physical hard disk, repartition according to the hard drive space of 60G.
Step S33, when the continuous frequency of utilization of the hard drive space of the 3rd pre-sizing is lower than during more than the 5th threshold value, upper once the physical space of hard disk is divided time, repartition according to the hard drive space of the first pre-sizing.Such as, accept above-mentioned example, when the continuous access times of the hard drive space of 60G are lower than 2 times, when next time divides this physical hard disk, repartition according to the hard drive space of 10G, the object of this step prevents corpse hard disk.
Wherein, the hard drive space of the pre-sizing of hard drive space < the 3rd of the pre-sizing of hard drive space < second of the first pre-sizing, and arranged by User Defined.3rd threshold value >=the 4th threshold value >=the 5th threshold value, same, arranged by User Defined.
In the present invention, in the actual use procedure of physical hard disk, periodically physical space is repartitioned.Same, the number of times repartitioned, also because situation difference can be different.Reason is identical with distribution hard drive space size, repeats no more herein.
