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.
Further, the performance strategy is under the premise of ensureing that system performance is optimal, by adjusting storage resource
The switching time of utilization rate and disk realizes the switching of disk power consumption state.
Further, the energy consumption strategy is under the premise of ensureing that system energy consumption is minimum, by adjusting storage resource
The switching time of utilization rate, system performance and disk realizes the switching of disk power consumption state.
Further, the disk power consumption switchover policy is under the premise of the switching time for ensureing disk is optimal, is led to
Control utilization ratio of storage resources and system performance are crossed, realizes the switching of disk power consumption state.
Implement the embodiment of the present invention, have the advantages that：
It is provided in an embodiment of the present invention based on the disk power consumption state switching method sporadicly asked, first obtain what is sporadicly asked
Corresponding disk integrated information under historical record and every time fragmentary request；Further according to historical record, analyze and determine sporadicly please
The regularity of distribution in sudden period and non sudden period is sought, with reference to disk integrated information, formulates the switching of disk power consumption state
Strategy；When detecting the in magnetic disc i/o mouth first fragmentary request, according to the first fragmentary request, corresponding disk power consumption is performed
State switchover policy.Perception compared with the prior art in face of sporadicly asking is insufficient, and technical solution of the present invention can carry out in time
Disk power consumption state switches, and raising system is to the response speed sporadicly asked.
Description of the drawings
Fig. 1 is provided by the invention based on the flow of a kind of embodiment of disk power consumption state switching method sporadicly asked
Schematic diagram.
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 provided by the invention based on a kind of embodiment of disk power consumption state switching method sporadicly asked referring to Fig. 1
Flow diagram, the method comprising the steps of 101 to step 103, and each step is specific as follows：
Step 101：Corresponding disk integrated information under obtaining the historical record sporadicly asked and sporadicly asking every time；It should
Disk integrated information includes：The switching time of utilization ratio of storage resources, system performance and disk.
Step 102：According to historical record, analyze and determine point of the fragmentary request in sudden period and non sudden period
Cloth rule with reference to disk integrated information, formulates disk power consumption state switchover policy；The disk power consumption state switchover policy includes：
Performance strategy, energy consumption strategy and switching time strategy.
The regularity of distribution that the technical solution of the present embodiment was sporadicly asked by the non sudden period and its burst period it is latent
In relationship, determine fragmentary request and utilization ratio of storage resources, performance, with switching time of the disk between different power consumption states it
Between association, so as to clearly sporadicly asking the influence of action opportunity, system performance and energy consumption switched to disk power consumption state.
In the present embodiment, performance strategy is under the premise of ensureing that system performance is optimal, by adjusting storage resource
The switching time of utilization rate and disk realizes the switching of disk power consumption state.Energy consumption strategy is is ensureing that system energy consumption is minimum
Under the premise of, by adjusting utilization ratio of storage resources, system performance and the switching time of disk, realize the switching of disk power consumption state.
Disk power consumption switchover policy be ensure disk switching time be optimal under the premise of, by control utilization ratio of storage resources and
