Abstract
The invention relates to the technical field of computer storage, in particular to a cross-array mirroring method. The cross-array mirroring method comprises the following steps: a host computer writes data into a gateway, the gateway simultaneously writes and stores the data into a first storage array and mirrors the data into a second storage array, the first and second storage arrays send feedback information to the gateway after successfully writing the data, and the gateway sends the feedback information to the host computer. According to the method, cross-array mirroring storage is implemented through the gateway, so that the data between the first and second storage arrays can be kept consistent; mirroring can be locally and remotely deployed, and the method is high in data protection degree and data backup efficiency.
Description
Technical field
The present invention relates to computer memory technical field, be specifically related to a kind of across array mirror method.
Background technology
In Computer Storage field, it is big that array stores is capable of memory capacity, access efficiency high, in some storage systems, the access of array is undertaken by gateway by server, different arrays are commonly stored different pieces of information, it is easy to cause the unicity of data, it is impossible to accomplish effective backup.
Summary of the invention
In order to solve above-mentioned technical problem, the invention provides a kind of across array mirror method, by gateway, the data between different arrays being carried out real-time mirror image, thus effectively realizing data backup.
In order to achieve the above object, the technical solution adopted in the present invention is, a kind of across array mirror method, the method applies to the storage system at least with two storage arrays and gateway, and gateway is connected with two storage arrays respectively and main frame connects, and comprises the following steps:
Main frame writes data into gateway,
Gateway writes data into simultaneously and receives the first storage array, and by data image to the second storage array,
Feedback information is sent to gateway after first storage array and the success of the second storage array write data,
Gateway sends feedback information to main frame.
Further, described gateway is the gateway with mirror image data write.
Further, described first storage array and the second storage array are solid-state storage array or disk memory array.
The present invention is by adopting technique scheme; compared with prior art; have the advantage that the present invention is undertaken across array mirrored storage by gateway; the data between the first storage array and the second storage array are made to keep consistent; mirror image can at local disposition; can also disposing at far-end, data protection degree is high, and data backup efficiency is high.
Accompanying drawing explanation
Fig. 1 is the structural representation of embodiments of the invention.
Detailed description of the invention
In conjunction with the drawings and specific embodiments, the present invention is further described.
As a specific embodiment, as it is shown in figure 1, one is across array mirror method, the method applies to the storage system at least with two storage arrays and gateway, and gateway is connected with two storage arrays respectively and main frame connects, and comprises the following steps:
Main frame writes data into gateway,
Gateway writes data into simultaneously and receives the first storage array, and by data image to the second storage array,
Feedback information is sent to gateway after first storage array and the success of the second storage array write data,
Gateway sends feedback information to main frame.Described gateway is the gateway with mirror image data write.Described first storage array and the second storage array are solid-state storage array or disk memory array.The present invention is undertaken across array mirrored storage by gateway so that the data between the first storage array and the second storage array keep consistent, and mirror image can at local disposition, it is also possible to dispose at far-end, and data protection degree is high, and data backup efficiency is high.
In the present embodiment, two storage arrays all adopt disk memory array, and this disk memory array has the advantage that by multiple disks being organized together as a logical volume offer disk leap function；It is written in parallel to/reads multiple disk to improve the speed accessing disk by data are divided into multiple data block (Block)；Fault-tolerant ability is provided by mirror image or verification operation.Disk memory array is to control being connected with each other of multiple hard disk by a hard disk controller, makes the read-write of multiple hard disk synchronize, and reduces mistake, increases the technology of efficiency and reliability.Magnetic disc array card is then the hardware product realizing this technology, and magnetic disc array card has a special processor, also has special memory, for high speed buffer data.Use disk array card server that the operation of disk is just processed either directly through RAID card, therefore do not need substantial amounts of CPU and system memory resource, the performance of disk subsystem will not be reduced.The special processing unit of RAID card is operated, and its performance to be significantly larger than conventional non-array hard disk, and safer more stable.
Although specifically showing in conjunction with preferred embodiment and describing the present invention; but those skilled in the art should be understood that; in the spirit and scope without departing from appended claims invention defined; the present invention can be made a variety of changes in the form and details, be protection scope of the present invention.
