Abstract
The present invention provides a kind of storage off-line data moving method based on CA ports, belong to Data Transference Technology field, the present invention passes through optical fiber/network connection between two storage disk arrays, so that by the volume data copy of source storage to target storage end in the form of block number evidence, access of the application server to storage can be suspended during copy, after the completion of data copy, application server can access target storage end at any time.The method that third party software need not be borrowed.
Description
Technical field
The present invention relates to Data Transference Technology, more particularly to a kind of storage off-line data moving method based on CA ports.
Background technology
Brand-new IT development trends form new challenge to storage system, and data turn into the maximum invisible money of user
Production, each storage manufacturer can all release high standard, the high-performance of oneself and obtain disk array to meet client to data volume/performance every year
Requirement, accordingly, for will be particularly important on the Data Migration of original disk array to newest equipment for client.Existing
Under technical background, in data transference package, user and manufacturer typically can be by the 3rd softwares by the number in former storage disk array
According to being then written to after reading in new storage device.Between the multiple read-write of data, the uniformity of data can not be completely secured,
Also to be that third party software is paid accordingly so first to carry out the data backup of former disk array before data transference package
Expense, substantial amounts of physical resources and financial resources are expended, while do not ensure that Data Migration disposably can use.
The shortcomings that existing way, is that storage end can only be scheduled to come from application service for destination end, reception that can only be passive
The read-write requirement of device, and can not actively initiate request of data.
The content of the invention
In order to solve the above technical problems, the present invention proposes a kind of storage off-line data migration side based on CA ports
Method.
The technical scheme is that：
A kind of storage off-line data moving method based on CA ports, passes through optical fiber/network between two storage disk arrays
Connection, so as to which the volume data copy by source storage in the form of block number evidence arrives target storage end, it can suspend during copy using taking
It is engaged in access of the device to storage, after the completion of data copy, application server can access target storage end at any time.
Specifically include following aspects：
1st, there are " CA patterns " and " starter " both of which in CA ports, and when selecting " CA patterns ", storage end can only passively connect
The data write/read request from application server is received, now, CA ports can only be used as destination end
2nd, when client needs to carry out Data Migration, two disk arrays are connected to one by way of direct-connected or interchanger
Rise, and the CA ports of destination equipment are arranged to " starter " pattern, destination equipment can be regarded an application service
Device, destination equipment will initiate reading and writing data request to source device, the volume data of source device copied in the form of block
Onto destination equipment, so as to realize Data Migration；But suspend the access of application server during Data Migration；
3rd, carried out data transmission between source device and destination equipment by several paths, while in storage software systems
The process of Data Migration is checked on gui interface at any time, at any time pause and turn-on data copy procedure；
4th, after data copy is completed, destination equipment can carry out data comparison with source device；Two kinds of way of contrast：Quickly
Contrast and complete contrast；
Rapid comparison only contrasts the data block at volume top；
Complete contrast refers to comprehensively contrast the data block in volume.
5th, after the completion of above-mentioned action, Data Migration is properly completed, and can now be switched back to destination equipment CA ports
" CA patterns ", application server may have access to destination equipment.
The beneficial effects of the invention are as follows
Cost-effective, this method is not required to only need two storage devices to complete Data Migration by third party software again；
Data integrity is secure, and in the moving method, directly purposefully equipment initiates copy request, volume to source device
Data are copied directly in the form of block in the equipment of destination, and volume data are compared comprehensively after the completion of copy, effectively
Completion and the uniformity of data are ensured.
Brief description of the drawings
Fig. 1 is data flow diagram under CA patterns；
Fig. 2 is data flow diagram under starter pattern.
Embodiment
More detailed elaboration is carried out to present disclosure below：
Storage off-line data moving method proposed by the present invention based on CA ports mainly includes procedure below：
1st, storing CA ports in the present invention has " CA patterns " and " starter " both of which, when selecting " CA patterns ", storage
Data write/read request of the reception from application server that can only be passive is held, as shown in figure 1, now, CA ports can only be used as mesh
Mark end.
2nd, when client needs to carry out Data Migration, two disk arrays need to only be connected by way of direct-connected or interchanger
Be connected to together, as shown in Fig. 2 and the CA ports of destination equipment are arranged to " starter " pattern, can be by destination equipment
As an application server, destination equipment will initiate reading and writing data request to source device, by the volume number of source device
The form of block is copied in the equipment of destination according to this, so as to realize Data Migration.But can suspend during Data Migration should
With the access of server.
3rd, can be carried out data transmission between source device and destination equipment by mulitpath so as to ensure data
The high efficiency and reliability of transmission.The process of Data Migration can be checked at any time on the gui interface of storage software systems simultaneously
Also can suspend at any time with turn-on data copy procedure, to ensure the startup at any time of Client application.
4th, after data copy is completed, to ensure data consistency, destination equipment can carry out data with source device
Contrast, two kinds of way of contrast：Rapid comparison and complete contrast.Rapid comparison only contrasts several data blocks at volume top, Ci Zhongfang
It can be resumed production as early as possible under formula.Complete contrast refers to comprehensively contrast the data block in volume, and such a mode contributes to
Ensure the integrality after Data Migration.
5th, after the completion of above-mentioned action, Data Migration is properly completed, and can now be switched back to destination equipment CA ports
" CA patterns ", application server may have access to destination equipment.
