Specific implementation mode

Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation describes, it is clear that described embodiments are only a part of the embodiments 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 the flow diagram of the first embodiment of method for writing data provided by the invention, the method packet referring to Fig. 1 It includes：

S101, in response to the write-in sector requests that the operating system of computer is sent, driving is asked according to said write sector Seek the sector number for obtaining sector data and the computer to be written；

S102, the driving obtain N according to the unique identifier of the sector number and the preconfigured computer The address of a loaded server；

S103, the driving send institute to N number of loaded server respectively according to the address of N number of loaded server State sector number, the unique identifier and the sector data；

S104, N number of loaded server are receiving the sector number, the unique identifier and the sector number According to rear acquisition current time, the time data memory as the sector data；

S105, N number of loaded server is respectively by the time data memory, the unique identifier of reception, institute It states sector number and the sector data carries out corresponding storage.

In the present embodiment, the operating system of computer is sent out when needing to write data into the hard disk of computer to driving Send write-in sector requests；For example, when operating system generates data in the process of running, or need the number of External memory equipment When according to the hard disk that computer is written, then write-in sector requests are sent to driving.

In the present embodiment, N is the positive integer more than or equal to 1；The ground driven according to N number of loaded server Location sends the sector number, the unique identifier and the sector data to N number of loaded server respectively, including：

The driving is separately connected N number of loaded server according to the address of N number of loaded server；

The driving sends the sector number, the unique identifier and described to the N number of loaded server respectively Sector data.

In a kind of optional embodiment, the driving is pre-configured with the unique identifier of the computer, including：

Before the write-in sector requests sent in response to the operating system of computer, the driving obtains the computer Machine information；

The unique identifier of the computer is generated according to the machine information.

The unique identifier of different computers is different.Each loaded server is according to the unique identifier, described When sector number and time data memory store the sector data, storage organization may be considered with a Hash The index structure of table (hash table) stores, and the unique identifier of computer is the index value of Hash table；Sector number is also Hash The index value of table；Time data memory is also the index value of Hash table.Therefore, in the data of loaded server storage, The corresponding data of the unique identifier meaning computer can be indexed on loaded server by the unique identifier； The unique identifier meaning meter can be indexed on loaded server by the unique identifier and the sector number The corresponding sector data in sector number meaning sector on calculation machine；Pass through the unique identifier, the sector number and institute The sector number on the unique identifier meaning computer can be indexed on loaded server by stating time data memory Sector data corresponding with the time data memory in all data of signified sector.

The sector number is obtained by the driving, and according to the sector number and the preconfigured meter The unique identifier of calculation machine obtains the address of N number of loaded server, passes through the unique identifier, the sector number and data Storage time mark is stored in the data in loaded server, to realize the sector that operating system will be written to local computer Data are stored by driving to N number of loaded server, and avoiding leads to loss of data because of the damage of local computer disk, and Dilatation is carried out to memory space by N number of loaded server, even if the data to be written are held more than local computer disk space Amount, without replacement hard disk, to reduce dilatation difficulty, when having saved cost, and having distinguished different by time data memory Between the data that store, avoid that former data cover is improved flexibility and the reliability of data storage when new data is written.

The present invention also provides a kind of second embodiments of method for writing data, and the method includes above-mentioned data write-in sides Step S101~S105 in the first embodiment of method, further defined it is described driving according to the sector number and in advance The unique identifier of the computer of configuration obtains the address of N number of loaded server, including：

In a kind of optional embodiment, the meta server is receiving the sector number and the unique mark Driving described in Fu Houxiang returns to the address of N number of loaded server, including：The meta server according to the sector number and The unique identifier obtains the address of N number of loaded server；The meta server is to corresponding to the unique identifier Driving return to the address of N number of loaded server.It realizes when multiple drive to the same meta server sends fan When area numbers with unique identifier, different driving is distinguished by unique identifier.

In a kind of optional embodiment, the network that is driven through sends the sector number to the meta server With the unique identifier of the preconfigured computer.

It is loaded server of the computer scheduling for sector data to be written by meta server, and by uniquely marking Know symbol and distinguish different computers, it is that multiple computers are serviced to be easy to implement through a meta server, improves dispatching efficiency； By meta server N number of loaded server is returned to the driving after receiving the sector number and the unique identifier Address, convenient for being managed collectively to loaded server group so that driving quick obtaining loaded server address, improve Write efficiency.

The present invention also provides a kind of 3rd embodiments of method for writing data, and the method includes above-mentioned data write-in sides Step S101~S105 in the first embodiment of method, having further defined the method for writing data further includes：

It should be noted that by the time data memory, the unique identifier, the sector number and described N number of The address of loaded server corresponds to store to said write and record, then N number of loaded server and N number of loaded server Address all correspond to the unique identifier；The address of N number of loaded server and N number of loaded server is all corresponding In the unique identifier and correspond to the sector number；The ground of N number of loaded server and N number of loaded server Location all corresponds to the unique identifier, the sector number and corresponds to the time data memory；N number of load services The address of device and N number of loaded server all corresponds to the unique identifier, the sector number and data storage Time.

I.e. by by the time data memory, the unique identifier, the sector number and N number of load services The address of device corresponds to store to write-in and record, convenient for meta server according to write-in record search and the time data memory, institute State the address of unique identifier, the corresponding loaded server of the sector number, and by the address found issue driving for The driving for reading data is needed to obtain sector data from corresponding loaded server according to address.
