Abstract

The invention provides a data copying management device and a data copying method of the data copying management device. The data copying method comprises the following steps that a Hash algorithm is adopted for obtaining the Hash values of a plurality of source data blocks formed by source data sub blocks; the Hash values are sent to a target storage side so that the target storage side judges whether the source data blocks are directly generated by the target storage side or the source data blocks are sent to the target storage side by the source storage side on the basis of the received Hash values; when the first feedback fed back by the target storage side is received, the source data blocks are ignored; when the second feedback bed back by the target storage side is received, the source data blocks are sent to the target storage side. Through adopting the mode, the copying speed on the special data blocks can be accelerated, so the CPU (central processing unit) and the network resources are saved, and the copying time is reduced.

Description

technical field [0001] The invention relates to the technical field of data copying, in particular to a data copying management device and a data copying method thereof. Background technique [0002] At present, with the increasing demand of various terminals and communication services, copying source data from one physical storage to another physical storage, or copying data from one virtual storage to another virtual storage has become more and more frequent , based on the limitations of the CPU (Central Processing Unit, central processing unit) and IOPS (Input / Output Operations Per Second, the number of read and write operations per second) of physical storage when multiple data copy processes are carried out simultaneously, how to reduce the resulting Copying time has become an important means for operators to enhance their competitiveness. [0003] In the prior art, the array integration application interface technology (vStorage API for Array Integration, VAAI) has be...
