Description
Technical field
The present invention relates to field of cloud computer technology, specifically a kind of physical store dispatching method and cloud main frame establishment side
Method.
Background technology
One big feature of cloud platform is high resiliency, you can according to business load, flexibly to increase or decrease cloud master in batches
The quantity of machine, to tackle the peak traffic of burst, the utilization rate of hardware resource is improved, the cloud main frame refers to simulate by software
There is complete hardware system function, the complete computer that operates in a completely isolated environment, also referred to as void
Plan machine.And can also need to create different cloud hard disks because of business demand while creating cloud main frame, it is how that cloud main frame or cloud is hard
Disk is distributed in preferable physical host or physical store and is just particularly important, and the cloud hard disk refers to what is simulated by software
Disk, it is consistent with physical disk function, it can be used with carry to cloud main frame；The physical host is used to provide the hard of the service of calculating
Part equipment, also referred to as server；The physical store is used for the hardware device for providing storage service, can be one piece of hard disk,
It can also be network storage.
Under normal circumstances, it is simply on the basis of cloud main frame when carrying out scheduling of resource, is carried out in turn by physical host
Distribution, create and created cloud hard disk further according to physical store workable for physical host after cloud main frame.But this method is simultaneously
Really uniformly resource can not be allocated.If the cloud main frame specification that batch creates is different, or the cloud that each cloud main frame needs
Hard-disk capacity is different, it is possible to which it is excessive the resource occupation of part main frame occur, or because storage deficiency causes to lead corresponding to main frame
The computing resource of machine can not be used effectively.
Therefore, a kind of new technology is needed badly, to avoid above mentioned problem.
The content of the invention
The technical assignment of the present invention is to be directed to above weak point, there is provided a kind of physical store dispatching method and cloud main frame wound

The establishment process of 1 pair of cloud main frame is described in detail below in conjunction with the accompanying drawings：
Step 1, the precondition for carrying out scheduling of resource.
, it is necessary to clearly know that the root disk size of the cloud main frame to be created needs, cloud main frame want the data of carry before scheduling
The characteristic of disk quantity, capacity and data disks（It is required that IO performances are high or are only used for achieving）
Step 2, scheduling of resource flow.
Exemplified by creating the scheduling flow of single cloud main frame：
11）Dispatch physical host resource：
The CPU and internal memory needed first according to cloud main frame is created, select all physical hosts that can create the cloud main frame, and root
Bit-reversed is carried out according to cloud host number can be created.Handled successively by the Host List after sequence, carry out physical memory resources
Scheduling（Step 2）.
22）Dispatch physical memory resources：
2.1st, the relevant information for all physical stores that main frame can use, including active volume, storage characteristics are obtained, storage is used
On the way（Root disk, data disks can be created）.
2.2nd, select the storage that purposes is " can create root disk ", Bit-reversed by measure, and by first store can
With capacity compared with the capacity of cloud main frame root disk, if off-capacity, currently stored affiliated physical host is marked as not
It can use, and return to step 2.1 handles next physical host.Otherwise, storage active volume is subtracted into root disk size, record should
Storage mark.
If 2.3 cloud main frames need carry excessive data disk, storage of the purposes for " data disks can be created " is selected, checks storage
Whether matched with the characteristic of data disks, and record matching degree（Storage and data disks can have multiple characteristics, identical characteristic simultaneously
More, matching degree is higher, and storage is actually the disk array being made up of polylith hard disk, according to the difference of usage scenario, selects
Disk would also vary from.For example, under the scene of monitoring or archives data, it will usually which use is relatively low by performance but holds
The storage of larger hard disk composition is measured, and under the very big scene of the regular read-write repeatedly of needs or data access amount, generally
The higher storage formed such as SSD or SCIS hard disks of performance can be selected.For different types of storage, we maintain one for it
Tag metadata is organized to indicate its characteristic, such as：The storage that relatively low but larger capacity hard disk forms by performance we can be
It safeguards the tag metadata of " archive ", " Large Copacity " etc；Can be its maintenance such as " high property if the storage of SSD compositions
The tag metadata of energy ".One storage can set multiple marks according to its capacity characteristic, usage scenario, performance characteristics etc. for it
Sign metadata.When request for data disk, according to the usage scenario of data disks data disks can be selected to create with what
In the storage of kind of label, multiple labels can be selected, are then matched by label, if a tag match must one
Point, the storage of final choice highest scoring creates data disks）.
Storage is ranked up according to matching degree positive sequence, active volume inverted order, and successively held memory capacity and data disks
Amount is compared, and selects first storage that can create data disks, active volume is subtracted into data disks capacity, records the storage
Mark.If the data disks can be created by not storing, mark it is currently stored belonging to physical host to be unavailable, and return to step
The 2.1 next physical hosts of processing.
If the 2.4, cloud main frame needs carry multi-block data disk, step 2.3 is performed repeatedly, until all data disks can divide
It is fitted on a storage.
33）If the storage that present physical main frame can use meets the root disk and data disks for creating cloud main frame, return
The physical host identifies and step 22）The storage mark of middle record.
44）To create multiple cloud main frames in batches, then step 11 can be performed repeatedly）-33）, until all cloud main frames can
Find matching physical host and storage.
By embodiment above, the those skilled in the art can readily realize the present invention.Herein
Apply specific case to be set forth the principle and embodiment of the present invention, the explanation of above example is only intended to help
Understand the method and its core concept of the present invention.It should be pointed out that for those skilled in the art, do not taking off
