Abstract
The invention relates to the field of computer data processing, a double living function of data storage is achieved, data are stored after data processing is conducted, the data consistency of the data is achieved between two storage, and when one storage is broken, the data can be accessed through the other storage; accordingly, the safety of the data is improved, and the data of a user are effectively protected.
Description
Technical field
The present invention relates to a kind of dual-active technology based on storing, belonging to Computer Data Security process field.
Background technology
In recent years, along with the continuous increase of data volume, people be in large data age.And data also seem more important in the life and work of people, so, for the storage problem of data, also become an emphasis of computer nowadays data security arts.In society now, data store, and have obtained well universal.
Data storage is the information needing in the temporary file that produces in process of data stream or process to search.Data are recorded on computer-internal or exterior storage medium in a certain format.Data storage will be named, and this name will reflect the composition implication of information characteristics.Data stream reflects the data flowed in system, shows the feature of dynamic data; Data store data static in reflection system, show the feature of static data.
In storage market, store classification (as Fig. 1) and be divided into according to type of server: the storage of closed system and the storage of open system.The servers such as closed system mainly refers to large scale computer, AS400; Open system refers to the server based on comprising the operating systems such as Windows, UNIX, Linux.The storage of open system is divided into again: built-in storage and plug-in storage.Plug-in storage is divided into according to the mode connected: direct-connected storage (Direct-Attached Storage is called for short DAS) and networking store (Fabric-Attached Storage is called for short FAS).Networking stores and is divided into again according to host-host protocol: network insertion stores (Network-AttachedStorage is called for short NAS) and storage area network (Storage Area Network is called for short SAN).
The storage of present stage mainly has following three kinds:
1. direct-connected storage (DAS)
This storage mode of DAS is the same with our common PC storage architecture, and External memory equipment is all directly be articulated in server internal bus, and data storage device is a part for whole server architecture.Its main reliance server host operating system carries out IO read-write and the storage system maintenance management of data, data backup and resume requires to take server host resource (comprising CPU, system IO etc.), the data stream main frame that needs to reflux arrives the magnetic tape station (storehouse) that server is connected to again, data backup takies server host resource 20-30% usually, therefore the daily data backup of many enterprise customers usually at dead of night or operation system is not busy time carry out, in order to avoid affect the operation of regular traffic system.When the data volume of direct-connected storage is larger, backup and the time of recovering will be longer, also larger with impact on the dependence of server hardware.So this method is difficult to extension storage capacity, and not supported data fault tolerance, can obliterated data be caused when server occurs abnormal.
2. network insertion stores (NAS)
The appearance that networking stores has adapted to the development trend that network becomes main information processing platform, and it has shared the function of data processing and storage administration, and data processing is responsible for by computing machine, and storage subsystem is responsible for the store and management of data.Network insertion storage is connected to by memory device on existing network, provides the equipment of data storage and file access services.Nas server is on private host, install the file server only with the operating system of the functions such as access privilege control, data protection and recovery simplified; required agreement connected to the network that it is built-in; can directly network, the user with authority can visit the file in nas server by network.Nas server directly connects disk array, and it possesses all features of disk array, high power capacity, high-effect, high reliability.But its memory property is lower, fiduciary level is not high.
3. storage area network (SAN)
SAN is a kind of dedicated network connecting memory device and storage management subsystem, specially to providing data store and management function.It a kind ofly special tells network, adopts optical-fibre channel to realize interconnection, connect storage array and file server host by fibre channel media.SAN not only can provide jumbo memory device, and geographically can disperse to dispose, thus alleviates the impact of mass data transmission for local area network communication.
Summary of the invention
The object of the invention is the dual-active function stored to realize data; by the process to data; again data are stored; data are made to reach data consistent between two storages; damage when a place stores; can another one store access data be passed through, from but improve the security of data, the more effective data protecting user.
When the same data of multiple servers Concurrency Access, metadata controller MDC prevents two-server from writing same Disk Locality simultaneously, and can not read inconsistent content because of having other servers in these data of renewal when ensureing that certain station server reads data content.
MDC is responsible for the access of coordination server to data, and it is positioned at outside the read-write path of data.Client is communicated with MDC by independently IP link, to obtain position and the data block resource assignment information of data, then passes through SAN network with block level read-write mode direct read/write disk.
Technical scheme of the present invention so realizes, and based on the dual-active technology stored, described method comprises the steps:
Client application sends a write request
Write request sends to MDC by LAN
This request of MDC process, uses dual-active technology to respond client to which disk block write data by LAN
Data are write direct in storage with linear speed by client
Realize storing dual-active

Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, in conjunction with once accompanying drawing, the present invention is further elaborated.Should be appreciated that concrete enforcement described herein is only in order to explain the present invention, is not intended to limit the present invention.
The object of the invention is the dual-active function stored to realize data; by the process to data; again data are stored; data are made to reach data consistent between two storages; damage when a place stores; can another one store access data be passed through, from but improve the security of data, the more effective data protecting user.
Described method comprises the steps:
Client application sends a write request
Write request sends to MDC by LAN
This request of MDC process, uses dual-active technology to respond client to which disk block write data by LAN
Data are write direct in storage with linear speed by client, realize storing dual-active
As Fig. 2, first client a application program sends a write request, write request sends to MDC by LAN, this request of then MDC process, by the tactful mode set in advance, carries out requirement analysis, by LAN by result feedback to client, indicate the position of storage, store, thus realize the dual-active of storage.
Claims (3)
1., based on the dual-active technology stored, described method comprises the steps:
(1) client application sends a write request.
(2) write request sends to MDC by LAN.
(3) this request of MDC process, uses dual-active technology to respond client to which disk block write data by LAN.
(4) data are write direct in storage with linear speed by client, realize storing dual-active.
