For tracking and the sudden access behavior in forecasting system；
By the behavioural analysis mathematical model, the first fragmentary request in the magnetic disc i/o mouth is detected.
Further, the legacy system behavior for obtaining block number evidence, specially：
By Trace journal files, the legacy system behavior of block number evidence is obtained.
Implement the embodiment of the present invention, have the advantages that：
It is provided in an embodiment of the present invention based on the tactful dispatching method sporadicly asked, the history for first obtaining cloud storage system is comprehensive
Record is closed, is established based on the scheduling strategy Cost Model sporadicly asked；It is sporadicly asked when detecting first in magnetic disc i/o mouth
When, according to scheduling strategy Cost Model, judge whether to perform the described first fragmentary request；Sporadicly please if it is, performing first
It asks；Otherwise, according to preset scheduling strategy, the first fragmentary request scheduling is given to other disks.Zero is faced compared with the prior art
The perception of star request is insufficient, and whether technical solution of the present invention performs fragmentary request by Cost Model measurement, is ensureing disk
Under the premise of performance, the energy consumption of disk is reduced to the maximum extent.
Description of the drawings
Fig. 1 is a kind of flow diagram of embodiment provided by the invention based on the tactful dispatching method sporadicly asked.
Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other without creative efforts
Embodiment shall fall within the protection scope of the present invention.
It is that a kind of flow of embodiment provided by the invention based on the tactful dispatching method sporadicly asked is shown referring to Fig. 1
It is intended to, the method comprising the steps of 101 to step 104, and each step is specific as follows：
Step 101：The history composite record of cloud storage system is obtained, is established based on the scheduling strategy cost mould sporadicly asked
Type；History composite record includes：The power consumption state record of utilization ratio of storage resources record, system load record and disk.
In the present embodiment, step 101 is specially：According to the history composite record of the cloud storage system of acquisition, determine to deposit
The power consumption state of resource utilization, the read-write ratio of I/O loads, the history number sporadicly asked and disk is stored up, and according to storage
Resource utilization, the read-write ratio of I/O loads, the power consumption state of the history number sporadicly asked and disk, are established based on fragmentary
The scheduling strategy Cost Model of request.Scheduling strategy Cost Model is used to integrate I/ in measurement system with multi-objective optimization theory
The influences of the Multiple factors to scheduling strategy such as the read-write ratio of O loads, number, the different power consumption states of disk sporadicly asked.
Step 102：When detecting the in magnetic disc i/o mouth first fragmentary request, according to scheduling strategy Cost Model, judge
Whether first fragmentary request is performed；If it is, perform step 103；Otherwise, step 104 is performed.
In the present embodiment, the detect in magnetic disc i/o mouth first fragmentary request in step 102, specially：Obtain block
The legacy system behavior of data, the behavioural analysis mathematical model of structure block data；Behavioural analysis mathematical model has recorded several
The description information and evaluation mechanism of sudden access behavior；Behavioural analysis mathematical model is for the burst in tracking and forecasting system
Property access behavior；Mathematical model is analyzed by the behavior, detects the first fragmentary request in magnetic disc i/o mouth.
In the present embodiment, the legacy system behavior of block number evidence is obtained, specially：By Trace journal files, block is obtained
The legacy system behavior of data.
In the present embodiment, judge whether that performing described first sporadicly please according to scheduling strategy Cost Model in step 102
It asks, specially：According to scheduling strategy Cost Model, calculate and perform the first cost cost sporadicly asked, if cost is at low cost
In predetermined threshold value, it is determined that perform the first sporadicly request；Otherwise, it determines the first fragmentary request is not performed.The size of predetermined threshold value
It can be configured according to the actual conditions of system.
Step 103：Perform the first sporadicly request.
Step 104：According to preset scheduling strategy, the first fragmentary request scheduling is given to other disks.
In the present embodiment, preset scheduling strategy is the loading condition and utilization ratio of storage resources according to each disk, will
First fragmentary request scheduling can also consider to minimum or minimum utilization ratio of storage resources disk is loaded and carry out weight
After calculating, it is scheduled to the highest disk of weight.
Therefore it is provided in an embodiment of the present invention based on the tactful dispatching method sporadicly asked, first obtain cloud storage system
The history composite record of system is established based on the scheduling strategy Cost Model sporadicly asked；When detecting first in magnetic disc i/o mouth
During fragmentary request, according to scheduling strategy Cost Model, judge whether to perform the described first fragmentary request；If it is, perform the
One fragmentary request；Otherwise, according to preset scheduling strategy, the first fragmentary request scheduling is given to other disks.Compared to existing skill
Art faces the perception sporadicly asked deficiency, and whether technical solution of the present invention performs fragmentary request by Cost Model measurement,
Under the premise of ensureing disk performance, the energy consumption of disk is reduced to the maximum extent.
One of ordinary skill in the art will appreciate that realizing all or part of flow in above-described embodiment method, being can be with
Relevant hardware is instructed to complete by computer program, the program can be stored in a computer read/write memory medium
In, the program is when being executed, it may include such as the flow of the embodiment of above-mentioned each method.Wherein, the storage medium can be magnetic
Dish, CD, read-only memory (Read-Only Memory, ROM) or random access memory (Random Access
Memory, RAM) etc..
The above is the preferred embodiment of the present invention, it is noted that for those skilled in the art
For, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also considered as
Protection scope of the present invention.
