Description of drawings
A kind of method flow synoptic diagram of automatic choosing dish when creating RAID that Fig. 1 proposes for the embodiment of the invention;
Fig. 2 is a kind of organizational form synoptic diagram of idle hard disk relevant information.
Embodiment
The embodiment of the invention proposes a kind of when creating RAID the method flow of automatic choosing dish as shown in Figure 1, comprise the steps:
Step 101: each hard-disk slots in the scanning disk disk array cabinet, obtain the relevant information of idle hard disk.Said relevant information includes but not limited to hard disk type, capacity, manufacturer, position of installing hard disk and hard disk praameter.Hard disk type can be to divide according to the hard-disk interface type; Comprise optical-fibre channel (FC, Fiber Channel), Serial Advanced Technology Attachment interface (SATA, Serial Advanced Technology Attachment), Serial Attached SCSI (SAS) interface (SAS) etc.; Also can divide according to the hard disk storage medium type; Like solid state hard disc (SSD, Solid State Disk) and mechanical hard disk, also can be to take all factors into consideration interface type and storage media types division.Said position of installing hard disk is cabinet No., the slot number at this hard disk place.Said hard disk praameter includes but not limited to whether support MAID, and rotating speed, interface rate, cache size etc.
A kind of organizational form of idle hard disk relevant information has been shown among Fig. 2.As shown in Figure 2, at first idle hard disk is divided by hard disk type, be divided into four types of FC, SATA, SAS, SSD to hard disk.Said division is according to both having comprised that interface type also comprised storage medium.Wherein, FC, SATA, SAS divide according to interface type, and these three types all is mechanical hard disk; SSD divides according to storage media types.Under every kind of hard disk type, divide into groups then, and under each hard disk, list hard disk praameter according to capacity and producer.
Step 102: the RAID set type and the capacity that receive user's input.
Step 103: according to the idle disk relevant information of having obtained, coupling can be set up the hard disk groups that meets said RAID set type and capacity requirement automatically.The implication that meets said RAID set type is that the quantity of hard disk in this hard disk groups must meet the hard disk quantity that the RAID set type requires; The implication that meets capacity requirement is that the calculated value of hard-disk capacity in this hard disk groups must be more than or equal to the RAID pool-size of user's input.The calculated value of hard-disk capacity is not an actual hard-disk capacity sum in the hard disk groups, but the capacity of the hard disk of capacity minimum multiply by the calculated value that the hard disk number in the hard disk groups obtains in the hard disk groups.
Step 104: judge whether to match hard disk groups, if, execution in step 105; Create failure information and failure cause and process ends otherwise return.
Step 105: the priority score of calculating each hard disk groups that matches according to priority policy.
Said priority policy includes but not limited to:
Type priority level strategy: the hard disk type in the hard disk groups under the hard disk is many more, and then priority score is low more, and is if hard disk is same type in the hard disk groups, then should strategy corresponding priorities score value the highest;
The quantity priority policy: the hard disk number is many more in the hard disk groups, and then priority score is low more;
Energy conservation priority level strategy; If the hard disk of (MAID, the Massive Arrays of Idle Disks) function that has MAID is arranged in the hard disk groups, each has hard disk accumulative total corresponding priority level score value of MAID function;
The parameter priority policy: the more parameters of each hard disk is approaching in the hard disk groups, and then priority score is high more.If hard disk all is the same model of same producer in the hard disk groups, then priority score is the highest.
The positional priority strategy: the different cabinet No. numbers of hard disk are many more in the hard disk groups, and then priority is low more, and are if all hard disks have identical cabinet No. in the hard disk groups, then should the strategy corresponding priorities the highest.
The final priority score of hard disk groups is the result that the priority score that above-mentioned each priority policy calculates is added up and obtains.
Step 106: select the highest hard disk groups of priority score to carry out the RAID creation.If there is the hard disk groups priority score more than two the highest and equal, then select hard disk groups according to following order (SATA, SAS, SSD, FC), carry out the RAID creation.If have the hard disk groups priority score more than two the highest and equal, and hard disk type is also identical, then select one of them hard disk groups to create the RAID group at random.
The above is merely preferred embodiment of the present invention, and is in order to restriction the present invention, not all within spirit of the present invention and principle, any modification of being made, is equal to replacement, improvement etc., all should be included within the scope that the present invention protects.
