Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is retouched in detail
State.
Below describe in, in order to illustrate rather than in order to limit it is proposed that such as particular system structure, interface, technology it
The detail of class, thoroughly cut to understand the embodiment of the present invention.However, it will be clear to one skilled in the art that there is no this
The embodiment of the present invention can also be realized in the other embodiments of a little details.In other situations, omit to well-known
The detailed description of device, circuit and method, in order to avoid unnecessary details hinders the description of the embodiment of the present invention.
Wherein, term "and/or" in the embodiment of the present invention, only a kind of incidence relation of description affiliated partner, represents
There may be three kinds of relations, for example, A and/or B, can represent：, there is A and B in individualism A simultaneously, individualism B these three
Situation.
Term " first " in description and claims of this specification and above-mentioned accompanying drawing and " second " etc. are for area
Not different objects, rather than be used for limiting particular order.
For server, object can be a certain file or a certain catalogue.
Catalogue is in order to realize object storage system (English：Object Based Storage System) TOC level
And rights management.If in server storage object be catalogue, the entitled directory name of object of this object, directory name typically with
"/" ends up, for example：The corresponding object of catalogue dir 1 is entitled：Dir 1/, the entitled dir 1/ of the corresponding object of its subdirectory dir 2
The entitled dir 1/dir 2/ of the corresponding object of subdirectory dir 3 of dir 2/ (plus the directory name of parent directory), subdirectory dir 2
dir‐3/.
If the object of storage is file in server, the object name of this object includes the path (mesh that this document is belonged to
Record name) and filename, and can not be ended up with "/".For example, the object entitled dir 1/dir 2/ of the catalogue of file obj 1 ownership
Dir 3/, the then corresponding object of file obj 1 entitled dir 1/dir 2/dir 3/obj 1.
Object storage system possesses storage area network (English：Storage Area Network, writes a Chinese character in simplified form：SAN height)
Feature and network attached storage (English that speed directly accesses：Network Attached Storage, writes a Chinese character in simplified form：NAS data)
Shared feature, there is provided the storage architecture of the data sharing of high reliability, professional platform independence and safety.Object storage system
System is also equipped with the feature of magnanimity extended capability, safe and reliable and efficient fusion it is adaptable to mass data storage and centralized backup should
With scene, Large Copacity can be brought for client, highly reliable, easy care, the easily value of extension.
S3 agreement is a kind of object storage agreement, and this agreement has been given up directory tree structure, employed a barrel object and (be appreciated that
For directory object) Layer 2 data model data storage, and it is semantic to have simplified read-write, is suitable to store magnanimity, destructuring
, read more than the data write.But, current S3 agreement does not have direct object renaming characteristic, and the renaming of object can only
By creating new object, by old object copies to new object and delete the sequence of operations such as old object and in a disguised form complete.
Additionally, current S3 agreement does not have directly multistage directory management function yet, the realization of multistage catalogue is typically logical
Cross special separator in object name to simulate, the renaming of this catalogue compared with the renaming of object, more complicated,
Efficiency is lower.
Fig. 1 shows the catalogue by the special separator "/" simulation in object name.Object name in conjunction with above-mentioned explanation can
Know, directory name need to add the directory name of parent directory with/ending, subdirectory name, and filename needs the catalogue plus its place catalogue
Name and end up can not be "/".Therefore, object name dir 1/ is corresponding is catalogue dir 1, and object name dir 1/dir 2/ is corresponding
It is the subdirectory dir 2 of catalogue dir 1, it to be the subdirectory of catalogue dir 2 that object name dir 1/dir 2/dir 3/ is corresponding
It to be file obj 1 under dir 3 catalogue that dir 3, object name dir 1/dir 2/dir 3/obj 1 be corresponding, object name dir
It to be file obj 2, object name dir 1/dir 2/dir 3/ under dir 3 catalogue that 1/dir 2/dir 3/obj 2 is corresponding
It to be file obj 3 under dir 3 catalogue that obj 3 is corresponding.
The renaming process of existing catalogue and file all includes the process backing up and the process deleted, but, backed up
The problem that journey and deletion process meeting initiating system I/O operation number of times are excessive, renaming efficiency is low.
Exemplary, as shown in Fig. 2 the method for the file f ile 2 RNTO new file 2 under dir 3 catalogue is：
By in a for the metadata data deep copy of dir 1/file 2 object dir 1/new file 2 to new name；Delete
The metadata of dir 1/file 2 and data.Wherein, metadata is in order to record storage location and the access control information of object.
As shown in figure 3, the method for catalogue dir 1 RNTO new dir 1 is：Copy dir 1 and its all subdirectories
Under all objects to new catalogue new dir 1, wherein, the metadata data of object will carry out deep copy；Delete
The metadata data of the had been friends in the past object under dir 1 and its all subdirectories, such as certain object size are 1 terabyte (English
Literary composition：Terabyte, writes a Chinese character in simplified form：TB), then just have the data of 1TB to need to delete.
As can be seen that the backup procedure in existing renaming method and process of deleting can initiating system I/O operation number of times mistakes
Problem many, that renaming efficiency is low.In the very big scene of TOC level relatively depth or quantity of documents, using existing heavy life
The difficulty that name method carries out renaming is larger.
The problem that IO number is excessive, efficiency is low leading to for existing renaming method, the embodiment of the present invention provides one
Plant renaming method, the server in object storage system creates be stored with object name and the corresponding relation of characteristics of objects
Mapping table, and characteristics of objects includes the general unique of the object of the storage address of the metadata data for denoted object
Identification code (English：Universally Unique Identifier, writes a Chinese character in simplified form：UUID), therefore, server is according to object
UUID can accurately get the data of a certain object, and so, server, can directly mapping after receiving renaming request
Penetrate the object name renaming meeting condition in relation table, and the process of backup and the process deleted need not be executed again, effectively drop
Low system I/O operations number of times, improve the efficiency of renaming.
Accordingly, the embodiment of the present invention additionally provides a kind of access method, and server obtains and certain from mapping table
The UUID of the corresponding object of one object name, because the UUID of object is used for the storage address of the metadata data of denoted object,
Therefore, the UUID of the object that server can get according to it reads the data of this object.
Renaming method provided in an embodiment of the present invention or access method are all applied to communication system.Fig. 4 is the present invention

Object takies size of memory space etc..
Specifically, at least one of this mapping table 400 object name can according to lexcographical order from small to large or from big to
Little be arranged in order, each object name uniquely correspond to a UUID.
Wherein, mapping table 400 can store in table form in server 40.Exemplary, including object
The form of the mapping table 400 of UUID of name and object is as shown in table 1.
It should be noted that the table 1 simply corresponding relation between schematic objects name and the UUID of object in table form
Storage form in server 40, be not to the corresponding relation between object name and the UUID of object in server 40
The restriction of storage form, certainly, corresponding relation between object name and the UUID of the object storage form in server 40 is also
Can be stored with other forms, the embodiment of the present invention does not limit to this.
Table 1
| Object name | The UUID of object |
| dir‐1/file‐1 | obj‐uuid‐1 |
| dir‐1/dir‐2/ | obj‐uuid‐2 |
| dir‐1/dir‐2/file‐2 | obj‐uuid‐3 |
| …… | …… |
| dir‐1/dir‐2/dir‐3/ | obj‐uuid‐4 |
Optionally, in mapping table 400, the feature of object can also include the last modification time of object, object
