Problems solved by technology

With the existing storage method, the application server still needs to store the A, B, C, D, and E data blocks in corresponding storage devices such as storage device 2, so that storage device 1 and storage device 2 will store The same data block, that is, data block C, data block D, and data block E, will cause waste of storage space resources and greatly reduce the utilization rate of storage space

Embodiment Construction

[0035] In step 301, the received data is divided into more than one data block whose size is X bytes.

[0036] Here, the received data may specifically be the data sent by the SAN sharing management software client received by the application server. Wherein, the above-mentioned X is a positive integer, and its value is related to the size of the data block stored in the storage system.

[0037] Step 302, generating corresponding identification information for each divided data block.

[0038] Here, the identification information may be in various forms, such as a data block index, or a data block name, etc., which are not specifically limited in this embodiment of the present invention. Preferably, if the above identification information is a data block index, the embodiment of the present invention can generate the data block index corresponding to each data block according to a preset algorithm such as MD5 algorithm.

[0039] In step 303, the data block corresponding to t...

Abstract

The present invention discloses a data storing method and a device thereof, wherein the method comprises the following steps: A. dividing the received data to more than one data block with the magnitude of X byte, wherein X is a positive integer; B. respectively generating corresponding identification information for each divided data block; and C. confirming the data block corresponding with theidentification information different from the identification information corresponding with the data block stored in the storing system. The invention does not directly store the received data into the storing system and firstly confirms the data requiring storing from the data which are to be received. Thus the usage factor of storing space is greatly increased.

Description

technical field [0001] The invention relates to the field of storage technology, in particular to a data storage method and device. Background technique [0002] At present, with the development of high-performance storage technology, a storage area network (SAN: StorageArea Network) shared storage system appears, wherein the SAN shared storage system uniformly manages storage devices in the SAN through SAN sharing software. [0003] see figure 1 , figure 1 It is a frame diagram of a SAN shared storage system in the prior art. like figure 1 As shown, the SAN shared storage system includes: an application server, a SAN shared management software client, a SAN shared management server and a storage system (wherein, the storage system includes more than one storage device), wherein the SAN shared management software client is connected to On the application server; the application server, the SAN shared management server, and the storage system communicate through the SAN s...
