Description
Technical field
The present invention relates to a kind of virtual memory access control technology, specifically a kind of distributed network storage architecture.
Background technology
The financial storm that is caused by the wall street subprime crisis has allowed the whole world all experience its pressing a burst of nip in the air, and any enterprise or mechanism all can't sit on the sidelines and be iImmune, this survival of the fittest just, and " remaining " person is king's a historical critical stage! Reduce the cost of enterprise by changing, raise the efficiency, it is extremely urgent to strengthen core competence of enterprises.
Meanwhile, also just breeding following new competition situation in the crisis.Under stern challenge, the enterprise with long term growth eye and strategy not only has been conceived to tide over crisis at the moment, is more preparing for the rapid development of next round.This is constantly reply variation, constantly a dynamic course that breaks through.Those isolated island formulas exist, ossify, labor-intensive architecture, the business demand that can't dynamic response changes, and the dynamic expansion of supporting business flexibly will become the stumbling-block of enterprise's long term growth.
In fact, IT system has developed into production platform, management platform, intercourse platform and the operation platform of core ... world's interconnection and interflow that just becoming, intelligent link; IT system has been no longer merely the cost center of enterprise also, helps enterprise to mould the innovation expulsive force of competitive power more especially.In order to help the better above-mentioned challenge of reply of enterprise, IT infrastructure should possess the ability that help enterprise successfully manages following challenge:
1, improve day by day cost pressure---the IT asset utilization ratio is low, complex management, operating cost height, the power that constitutes competition descends, can't sustainable development;
2, higher service expectation---more and more astute client wishes to obtain more to have quality services to experience from increasing assets, application and service;
3, manage and control new risk and threat---business transformation speeds up, traditional infrastructure faces unprecedented security, elasticity and compliance challenge;
4, make full use of the new technology of continuous appearance---must utilize more intelligence, have more the technology of adaptive faculty, for example cloud computing, the virtual and innovation of promoting business, raise the efficiency and capability of fast response.
Virtual store is a kind of system with intelligence structure, it will allow to store data with transparent effective and efficient manner on Disk and tape, the unified management disk space makes storage system can hold more data, also makes more user can share same system.Under virtual memory environment, no matter the back-end physical storage is any equipment, and what server and application system thereof were seen all is the logical image of its physical equipment.Even physical store changes, this logical image can not change yet, the system manager needn't be concerned about the rear end storage again, only need be absorbed in the managed storage space, all storage management operations, for example system upgrade, foundation and distribution virtual disk, change RAID rank, expansion storage space etc. are all many than being easy in the past, and it is easily simple that storage administration becomes.Under virtual memory environment, it is transparent that storage will become concerning the user, function difference, amount of capacity, device type and manufacturer that the user can be concerned about memory device how, all equipment will be by unified management, and give unified function such as Flashcopy, long-range calamity is equipped with etc.
Summary of the invention
Technical assignment of the present invention provides a kind of virtual resource pond that can create integration in whole enterprise, help IT department customer in response demand and realize the centralized management of resource more quickly, thereby significantly improve the dirigibility of IT infrastructure and a kind of distributed network storage architecture of responding ability.
Technical assignment of the present invention is realized in the following manner, comprises logical layer, virtual level and disk storage sub, and virtual level is between logical layer and disk storage sub; The all I/O of logical layer main frame will pass through virtual level; Virtual level comprises LVM logic manage module, Radi driving, block device administration module, 1394 disk drive and FC driven management module; Disk storage sub is made up of IDE disk array and two disk arrangements of FC disk array.
LVM logic manage module connects the Radi driving in the virtual level, and Radi drives the contiguous block device management module, and the block device administration module connects 1394 disk drive and FC driven management module.
1394 disk drive in the virtual level connect the IDE disk array in the disk storage sub, and the FC driven management module in the virtual level connects the FC disk array in the disk storage sub.
One or more storage unit in the disk storage sub are mapped as the storage unit MDisk (Managed Disk) of virtual level inside by LVM logic manage module, one or more Mdisk can be by virtual 1 storage pool (being called MDG) that turns to of block device administration module, and all storage pools to all I/O mouth of logical layer main frame all as seen.
(as Striped, Image Sequential) distributes virtual storage unit to storage pool, is called VDisk according to certain allocation strategy.
The all I/O of logical layer main frame must pass through virtual level inside, are equivalent to virtual level and will take over all I/O that come from main frame.Accomplish this point, virtual level will make the logical layer main frame can directly visit real disk storage sub seemingly.The realization of this virtual level depends on storage virtualization technology.The key concept of Storage Virtualization is that the logical expressions of actual physical storage entity and storage are separated, and application server is only come into contacts with the logical volume of distributing to them (or claiming empty volume), and need not be concerned about which physical store entity is its data be on.
Virtual level, can form a large-scale storage pool to the memory device in the different disk storage subsystem, some memory devices wherein exist with a unified logical device, can be prevented the information island of memory device by Servers-all visit in the system.Virtual store control and management module in the virtual level has a plurality of data paths to be connected with memory device, the concurrent work of a plurality of memory devices, and the logical layer main frame also can have many same virtual levels of data path, the concurrent work of mulitpath simultaneously.Can do and share the different manufacturers memory device, realize that unified management, long-range calamity are equipped with, functions such as local quickflashing backup and online data migration, other shares the Block level between the different storages of real realization.
A kind of distributed network storage architecture of the present invention has the following advantages:
1, can create the virtual resource pond of integrating in whole enterprise, help IT department customer in response demand and realize the centralized management of resource more quickly, thereby the dirigibility and the responding ability that significantly improve IT infrastructure increase the challenge that is brought to help you to tackle current information explosion effectively;
2, virtual store is a kind of system with intelligence structure, it will allow the user to store data with transparent effective and efficient manner on Disk and tape, the unified management disk space makes storage system can hold more data, also makes more user can share same system;
3, can carry out centralized control and management to diverse isomerism storage resources, thereby improve the availability of service application and the utilization factor of resource;
4, the storage resources in the IT architecture is managed, guarantee that they can be fully utilized by enterprise, be used fast, effectively, in real time by enterprise and reduce the business administration cost; Thereby, have good value for applications.
