Specific embodiment
To make purpose, technical scheme and the advantage of the embodiment of the present invention clearer, below in conjunction with the embodiment of the present invention
In accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is
The a part of embodiment of the present invention, rather than the embodiment of whole.Based on the embodiment in the present invention, those of ordinary skill in the art
The every other embodiment obtained under the premise of creative work is not made, belongs to the scope of protection of the invention.
The flow chart of the storage device wiring method embodiment that Fig. 1 is provided for the present invention, the storage device is by least one
Solid state hard disc（Solid State Disk, SSD）Combine to be formed with traditional data disks, the write-in functions of hard disk are by SSD sums
Support to realize jointly according to disk, as shown in figure 1, the method for the present embodiment can include：
S101, storage device obtain the attribute of data to be written.
For example, storage device can be hard disk or other equipment with store function, and the present embodiment is with hard disk act
Example is illustrated, because there is the major part of hard disk sector computer the functional area of write demand still to give tacit consent to the size of sector
It is worth for traditional 512B, therefore, still write in units of 512B when data are write to hard disk, that is to say, that to be written
The sizes values for taking up room of the data for entering can be the integral multiple of 512B, such as 3 512B, 2 512B, 10 512B, 19
512B etc..
It should be noted that prior art can lift the sizes values of the sector of hard disk to being 8 with 4KB
512B, that is to say, that hard disk can be read in units of 4KB and is written with, so the embodiment of the present invention is with the size of sector
It is worth and is illustrated for 4KB citings, write of any sector-size value more than the sizes values that the data of computer write take up room
Within the scope of the present invention, the such as sizes values of sector are 8KB, computer still with 512B writes, or, sector it is big
Little value is 8KB, and upgrading computer with 4KB to carrying out writing etc. within protection domain.
Further, the attribute of data can include big input and output (Input Output, IO) and little IO, wherein, IO
Size can be divided based on the size of a slitting, less than a slitting size IO be little IO, more than or equal to one point
The IO of bar size is big IO；One slitting size=(number -1 of the disk of RAID groups) * segment depth, slitting is same
In RAID groups, physical deflection identical several stripe units composition, segment depth be the block in a stripe unit
Number, block is the least unit of storage device read-write operation, and size is 512 bytes, and stripe unit is continuous on same hard disk
The element of the slitting of several block compositions.
If S102, storage device determine data for the first data, execution step S103 according to the attribute of data to be written；
If determining data for the second data, execution step S104 according to the attribute of data to be written.
For example, if storage device determines the data for little IO, execution step according to the attribute of data to be written
S103, however, it is determined that the data are big IO then execution steps S104.
Further, confirm that IO can if the RAID component bar sizes are 1M, but be write for big IO or little IO
IO be 10K, in fact at this time the attribute of IO should be determined as little IO, at this time just this 10K IO be write completely first
RAID；If slitting size is 100K, the I O size to be write is 101K, then this when just all writes the data of this 101K
In 2nd raid.
S103, storage device write first data into the memory block for belonging to a RAID using the characteristic of SSD quick responses
In, total storage size value of a RAID is equal at least about the capacity of a SSD.
Further, during the data of the sizes values that computer write is less than sector, such as but sector is 4KB number to be written
When according to the sizes values for taking up room being 3 512B, first reading computer write request target location, to be that SSD is corresponding belong to first
The data of one whole 4KB sectors of the memory block of RAID, then replace the legacy data of this 4KB data 3 512B sizes by
For new data, i.e., legacy data is covered with new data, the data of 3 for being written into 512B show with 5 512B's not replaced
There are data to merge into the data of a new 4KB, then the data write of this 4KB is belonged to into the memory block of a RAID.Due to
One RAID is supported by least one SSD, and SSD has the characteristic of quick response, you can with quickly reading and write diagnostics, can
To improve the writing speed of little IO.Time such as the data write conventional hard of 3 512B may be 1 second, but 3 512B
The time of the memory block of the RAID that data write SSD is supported may only be 10 milliseconds, greatly improve small data input IO
The time of write.
S104, storage device belong to the write of the second data in the memory block of the 2nd RAID, and total storage of the 2nd RAID is empty
Between sizes values be equal to total data disks capacity sum.
For example, when the data attribute of computer write is big IO, the data division of the sizes values of sector is equal in IO
Just write direct in the 2nd RAID, such as sector is 4KB, when the sizes values that big I/O data to be written takes up room are 8 512B,
Directly the data to be written write that this big I/O data is divided into two 4KB can be belonged in the memory block of the 2nd RAID, and not
Needs first read again from the 2nd RAID replaces again the data for finally writing this 2 4KB again, saves the time of write data.
If the sizes values that big I/O data to be written takes up room are more than 4K, and are unsatisfactory for the situation of the integral multiple of IO
Under, such as during 15K, 15K is done a rounding by 4K, such as can be processed with the data that rounding is a 15K, i.e. 15K will write
How many 4K units, only pre-read the part for being unsatisfactory for 4K, and the such as data of 15K roundings necessarily have a part less than 4K.If
Will be from address block（block）Where 0, a block as described above is 512B, and the data for writing a 15K are gone down, at this time
Its real address 0 is alignment, and data 15K to be write are not lined up, but is also that last 4k is not lined up, and at this time, is just only needed
Pre-read in last 4K data, do and merge, then write；And if to be to go to write a 15K where 1 from address block
Data, at this time address and size of data 15K are not 4K alignment, it is necessary to address and data size all registration process,
And in fact simply the parts of 4K end to end of this 15K data do not line up yet, 0 to 4K and 12K to 16K this part number is at this time just pre-read
According to, do and merge, then write.
It should be noted that although the present embodiment does not do any restriction with hard disk illustration with this, other storages set
From being caused according to the unit write after the lifting when standby write unit is lifted and computer or user equipment is write
Write it is slow using method provided in an embodiment of the present invention raising writing speed, so within protection domain.
Storage device wiring method provided in an embodiment of the present invention.Storage device obtains the attribute of data to be written；If
Data are determined for the first data according to the attribute of data to be written, then using the characteristic of solid-state hard disk SSD quick response by the
The write of one data belongs in the memory block of a RAID, and total storage size value of a RAID is equal at least about SSD
Capacity；If determining that data are the second data according to the attribute of data to be written, the write of the second data is belonged to into the 2nd RAID
Memory block in, total storage size value of the 2nd RAID is equal to the capacity sum of total data disks.So, storage sets
It is standby to be write using the data that the fast response characteristic of SSD is little input and output IO to attribute, to improve the speed of write
Degree, and data disks only process the data of big IO, data disks can be by the sizes values equal to sector in the data of this kind of big IO
Data are write direct, and with this speed of write is accelerated, and are reduced because the magnetic head of hard disk frequently reads and writes the change for bringing, and lift hard disk
Service life.Storage device is this to be lifted while can accelerate sector using the structure and storage mode of SSD and data disk storage
Writing speed of storage equipment afterwards, and then lift the performance of storage device.
The flow chart of storage device wiring method another embodiment that Fig. 2 is provided for the present invention, the present embodiment is storing
Equipment is that hard disk is illustrated, but with this does not do any restriction.As shown in Fig. 2 the method includes：
S201, hard disk belong to a RAID according to the storage size value of a RAID and the sizes values determination of memory block
Memory block number be M, and the sizes values of the storage size value according to the 2nd RAID and memory block determine and belong to second
The memory block number of RAID is N number of.
Further, the memory block number for being labeled as belonging to a RAID is caused to be not more than M by calculating memory block number,
The memory block number for being labeled as belonging to the 2nd RAID is not more than N.
Wherein, the storage size value of a RAID is according to the determination of the capacity of at least one SSD, the storage of the 2nd RAID
Space size value determines that the sizes values of memory block are a default definite value, and M, N are positive integer according to the capacity of total data disks.
For example, the storage size value of a RAID determines it can is basis according to the capacity of at least one SSD
RAID is determining the space size of RAID groups.If SSD is composition RAID10 ranks, so, the capacity of raid groups here
Should be 32GB, in 2 pieces of disks, have 1 piece of disk to be for doing data protection, that is to say, that the data on 2 SSD disks.
And it can be according to data disks that the sizes values of the storage size value according to the 2nd RAID and memory block determine
Number and the RAID being located determine that the termination capacity for being primarily due to storage device is the number with data disks and RAID groups
Rank it is related.Total capacity such as the 2nd RAID is equal to the capacity sum of total data disks：If RAID group ranks are
RAID10, then be multiplied by mirror set number equal to the capacity of data disks；If RAID group ranks are RAID3 or RAID5, equal to into
Member's disk number deducts 1, and the capacity of each disk is then multiplied by again；If RAID group ranks are RAID6, equal to member data disk
Number deducts 2, is multiplied by the capacity of each disk.Due to the capacity of each data disks it is different, therefore the capacity for being multiplied by data disks when
Wait, be defined by the capacity of that minimum disk of capacity in all disks constituted in RAID groups and calculated.
Such as, according to the above-mentioned storage size value for being calculated a RAID be 32GB, the memory space of the 2nd RAID
Sizes values are 128GB, and the sizes values of memory block are a default definite value, and such as 64M then can determine and belong to depositing for a RAID
Storage block number M=512, belongs to memory block number N=2048 of the 2nd RAID.
That is, when being subsequently marked to unlabelled memory block will with belong to a RAID memory block number not
More than 512, be not more than 2048 with the memory block number for belonging to the 2nd RAID is carried out as standard.Such as, the memory block of a RAID
1 is labeled as using a flag bit, the memory block of the 2nd RAID is labeled as 0 using a flag bit, if being then labeled as 1 storage
Block number has equalized to 512, then unlabelled other memory blocks are no longer labeled as 1, in the same manner, if being labeled as 0 memory block number
2048 are had equalized to, then unlabelled other memory blocks are no longer labeled as 0.
It should be noted that the capacity of above-mentioned SSD and data disks is only used for illustrating, the sizes values and mark of memory block
Mode is also illustration, does not do any restriction with this, and other numerical value and mark mode are within protection domain.
S202, hard disk will then belong to depositing for a RAID if it is determined that the memory block that M belongs to a RAID is otherwise fully engaged
Data in storage block are all dumped in the memory block of the 2nd RAID, and are emptied in M memory block for belonging to a RAID of occupancy
All data.
It should be noted that if 512 memory blocks for belonging to a RAID are otherwise fully engaged, i.e., each memory block is filled
Data are expired, and also there is vacant memory block and being labeled as in hard disk and belong to the 2nd RAID's but the storage that is not otherwise fully engaged
Block, then hard disk can at one's leisure between, i.e., when not reading and write any data, by the memory block of a RAID
Data are all dumped in the memory block or vacant memory block of the 2nd RAID, and proceed to needs to deposit vacant after vacant memory block
Storage block is labeled as belonging to the 2nd RAID.
S203, hard disk obtain the attribute of data to be written.
It should be noted that it can be that the data are little IO or big I/O data that acquisition is attribute, in above-described embodiment
Jing is described, and be will not be described here.
If S204, hard disk determine data for the first data, execution step S205 according to the attribute of data to be written；If root
According to the attribute of data to be written data are determined for the second data, execution step S208.
S205, hard disk determine that the first data need to write the memory block for belonging to a RAID.
Further, hard disk can utilize the characteristic of SSD quick responses to complete step S205～S207.
, according to all of memory block of default table item index, acquisition is all to be labeled as belonging to depositing for a RAID for S206, hard disk
The address of storage block and the address of all unlabelled memory blocks.
S207, hard disk write the first data in corresponding memory block according to the address of memory block.
For example, Fig. 3 for hard disk theory of constitution structural representation, as shown in figure 3, total memory space of hard disk can be with
It is that SSD and data disks are constituted together, SSD and data disks realize store function in bottom, and no longer as prior art
Caching is provided by SSD, by data disk storage.Such as a RAID can be constituted by 2 SSD, be then made up of 3 data disks
2nd RAID.Hard disk to a RAID and the 2nd RAID unified addressings, can distinguish the attribute of the data that user need to write, that is, count
According to sizes values, when data sizes values be less than sector, when being little I/O data, correspondence the first RAID address just can be by little IO
Data write SSD, and when for more than or equal to the data of the sizes values of sector, the address of the 2nd RAID of correspondence just can will be this kind of
Larger data write data disks.
Table 1 is default list item, there is two-layer MBA memory block address in hard disk（Lba, Logical Block Address), one
The individual LUN for corresponding to real memory space（Logical Unit Numbe, LUN）, each true Lba is
The Lba of LUN is 64M, and another is virtual Lba, is denoted as the Lba of block BLOCK.As shown in table 1, hard disk is by SSD and data disks
Total memory space of composition is mapped to the Lba of the Lba and BLOCK of LUN, and the Lba to LUN is numbered, the Lba of the LUN with
The Lba of BLOCK can mutually be uniquely determined with address.The Lba of each LUN can also be marked in this list item to be belonging to first
RAID or the 2nd RAID, can such as utilize the flag bit in the example above to be labeled as belonging to a RAID or second for 0 or 1
RAID。
When data to be written are the first data, look for whether having depositing for the 64M sizes for belonging to a RAID first
Storage block is used for storing first data, if it has, judging whether the memory block is filled with again；If be filled with, go to obtain
What other were not filled with belongs to the memory block of a RAID, if all memory blocks for belonging to a RAID are filled with, finds idle
64M sizes memory block, and the memory block is labeled as to belong to a RAID.Further, the RAID of SSD compositions can
With difference, e.g., polylith SSD composition RAID3 or RAID6 etc..
Table 1
Further, there can be preset table in hard disk, the form can increase to have each memory block on the basis of table 1
Address.Hard disk can be according to all of memory block of default table item index, using unlabelled memory block as first memory block, such as
The memory block of Serial No. 3 is first memory block, will be otherwise fully engaged in all memory blocks for being labeled as and belong to a RAID
Memory block be defined as the second memory block, the such as memory block of Serial No. 1 is otherwise fully engaged, and the memory block of Serial No. 5 is not
It is otherwise fully engaged, then the memory block of Serial No. 5 is labeled as into the second memory block, the address of the second memory block is obtained, by first
Data are write in the second memory block according to the address of the second memory block.Memory block such as the memory block of Serial No. 1 is accounted for completely
With the memory block of Serial No. 5 is also otherwise fully engaged, then obtain the address of first memory block, and the first data are deposited according to first
In the address write first memory block of storage block, and first memory block is marked to belong to a RAID, i.e., in the memory block of Serial No. 3
A RAID hurdles in mark 1.
S208, hard disk determine that the second data need to write the memory block for belonging to the 2nd RAID.
, according to all of memory block of default table item index, acquisition is all to be labeled as belonging to depositing for the 2nd RAID for S209, hard disk
The address of storage block and the address of all unlabelled memory blocks.
S210, hard disk write the second data in corresponding memory block according to the address of memory block.
For example, the preset table in hard disk can increase the address for having each memory block on the basis of table 1.Hard disk
Can be according to all of memory block of default table item index, using unlabelled memory block as first memory block, such as Serial No. 3
Memory block is first memory block, and the memory block not being otherwise fully engaged in all memory blocks for being labeled as and belong to the 2nd RAID is determined
