Description
Technical field
The present invention relates to computer memory technical field, relate in particular to embedded type virtual tape library parallel memory system.
Background technology
Along with the technology based on disk is more and more ripe, price constantly reduces, increasing manufacturer releases VTL (VTL), yet, the controller of present most VTL products all is based on separate unit PC hardware of server system on the market, even adopt PC server with enhanced scalability, its extended capability is still limited, and be integrated in many necessary function on the VTL controller, as: logical volume management, data compression, data de-duplication, verification automatically, encryption or the like also make the CPU of Single-Server can't bear the heavy load.
Summary of the invention
In view of the above problems, the objective of the invention is to introduce a kind of many VTL engine, make transfer of data, handle and disperse to realize, solve the technical scheme of VTL VTL functional limitation, system design mainly is divided into hardware components and software section, and hardware components comprises: intelligence expansion engine group, core switching system and memory cell.Operation core virtual tape pool management software on this platform, the parallel memory function of realization VTL system.Wherein:
(the controller mainboard all adopts embedded system development to described intelligence expansion engine for Intelligent Scalable Engine, ISE) system, and general structure simplifies, efficiently.Controller can be made up of many engines, and is not limited to one.Certainly, the user also can adopt the VTL VTL that has only an engine earlier, also can increase engine as required later on.In many engine configuration of described VTL VTL, can choose one wantonly as the master control engine, the master control engine is responsible for monitoring and is coordinated each engine work.The virtual machine hand is generated by the master control engine, and virtual drive and tape groove can dispose, be distributed on each engine by actual needs.For main frame or application, still can as using the logical tape library of a Daepori, use the virtual tape library of many engines.
Described internal core switching system mainly is two parts of branch IP network and SAN network.Wherein: IP network partly is responsible for distribution, the various piece Working Status Monitoring of internal control instruction.The SAN network portion is the rear end passage of each engine I/O data, adopts the 4Gb/s optical fiber link to realize the high-speed transfer of storage data.
Described memory cell constitutes to a plurality of disk storage unit that connect based on the SAN topological structure fully by one.Disk array and JBOD that various disks such as VTL VTL compatible FC, SATA, SAS constitute satisfy multiple storage demand, optimize the investment protection.
Software section comprises and moves backup software and server program on each main frame respectively, carry out transfer of data by switching system (IP/FC) and engine, make main frame by one in the parallel engines, other is a slave, main frame is configured the distribution that can realize driver, its function mainly realizes that by the vtl_cluster application program of oneself developing the vtl_c1uster on the main frame is by reading configuration information, by the control information switching system
Exchange of control information, and the vtl_cluster that controls on each slave according to the corresponding relation of slave ip and drive letter carries out the dynamic creation driver, engine each engine has partly created different drivers, server program on the main frame also is transported to the corresponding driving device for each backup software (for example agent), make when carrying out backup tasks, according to the corresponding relation of driver, use corresponding engine to serve like this for it, a plurality of main frames just can reach parallel storage truly.Described embedded type virtual tape library parallel memory system adopts parallel controller engine structure, the operating state of a tape library of many engines concurrent working emulation.Each engine hardware structure of controller is identical, all based on adopting custom-designed mainboard, and integrated custom-designed control chip and virtual tape library software on the mainboard.Parallel engines can extend to 32, configurable 2 the optical fiber host channels of each engine and 6 rear end optical fiber memory channels, the transmission rate of optical-fibre channel self adaptation 2Gb/sec and 4Gb/sec.
In system design, adopt between each engine and do not interrupt using, shielded Single Point of Faliure to the full extent, all simultaneously critical components (as power supply, fan) adopt arm processor and embedded OS, operation particular virtual software emulation tape library equipment on it, substitute half circuit half mechanical mode of mechanical tape library, specify certain engine as the master control engine, other engine is as the expansion engine.All I/O applications are all at first handled by the master control engine, and then the guiding I/O data stream is to the virtual tape drive and the virtual tape of the engine of appointment, the state of expansion engine by real-time update to the master control engine, so that master control engine centralized management and monitor whole VTL VTL system.If the shared same rear end of different engines optical fiber disk array memory device, when the read-write of the virtual drive on engine belonged to virtual tape on the other engine so, data were then transmitted by optical-fibre channel; If the rear end memory device of an engine and other engine does not have direct data channel, the data of interleaved need be by the IP network channel transfer between the engine so.Control Engine is supported from 1 to 32 mode of operation, forms cluster between each engine mutually, and single engine failure only can cause systematic function to descend temporarily, uses redundancy scheme, realizes high reliability; The concurrent working of many engines makes I/O performance and the memory capacity maximization of VTL.
