Description

Technical Field

[0001] The present invention relates to the technical field of computer data storage, and in particular to a virtual tape library gateway system based on a Blu-ray disc library and a management method thereof. Background Art

[0002] At present, the whole society is in the era of big data. The ways of generating data are diversified, and the amount of data generated is growing exponentially. The preservation of data is the basis of informatization and intelligence. In the field of cold data storage, the current mainstream storage method in the market uses tape libraries to save data. However, tape library products are limited by the use conditions of tape media, have strict environmental requirements, and have limited moisture resistance, drop resistance, and strong magnetic resistance. Even for offline storage, the entire tape needs to be reread regularly. Its improved version, the virtual tape library (Virtual Tape Library, VTL) with disk as the medium, has improved the response speed of the tape library, reduced the requirements of the working environment, and extended the service life of the medium, but the high energy consumption loss is too huge, and due to the defects of the magnetic medium itself, such products have not yet replaced the traditional tape library market on a large scale. However, in recent years, devices using large-capacity optical disks as storage media have gradually emerged in the market. The single-disk capacity of Blu-ray discs is mainly 100GB and 300GB, and Blu-ray discs with 500GB or even larger capacity are also being launched. Due to the storage characteristics of Blu-ray disc media, the defects of tape media can be well avoided. What is more outstanding is that the cost of saving data is very low, and the maintenance cost of offline storage is close to 0. Therefore, a virtual tape library product based on optical disk that is compatible with the characteristics of optical disk media and the market dependence behind the tape library and meets the concept of energy saving and environmental protection will have broad application prospects.

[0003] Among existing products, there are cases where a combination of disks and optical disks is used. In such products, the essential role of the disk is to serve as a carrier of the VTL and a cache for the optical disk library. However, from the actual use point of view, the disk used as the cache for the optical disk library artificially increases the data exchange process between the optical disk library and complicates the simple data transmission. The core is to avoid directly using the optical disk library as a simulation of the tape library, and to separate the direct call of the VTL interface to the optical disk library. The complexity of cache management has become a factor that restricts the reliability of such products. In order to solve the shortcomings of the above products, we propose a virtual tape library gateway system based on the Blu-ray optical disk library. Summary of the invention

[0081] Specifically, Figure 3 As shown, when the upper application server sends the SPC / SSC standard tape data read instruction to the virtual tape library gateway server through the SPC / SSC protocol interface module, the instruction conversion module receives the SPC / SSC standard tape data read instruction and parses the instruction to obtain the corresponding instruction, then the instruction conversion module obtains the optical disc read instruction corresponding to the tape read from the instruction set, thereby converting the tape data read instruction into the SMC / MMC standard optical disc read instruction, the SMC / MMC protocol interface module sends the SMC / MMC standard optical disc read instruction to the Blu-ray optical disc library controller, the Blu-ray optical disc library controller obtains the ID of the corresponding optical disc cartridge according to the optical disc read instruction, queries the Blu-ray optical disc library, obtains the corresponding optical disc cartridge position information and determines whether the optical disc cartridge is located in the optical drive assembly, if so, obtains the physical address of the optical disc corresponding to the logical address from the metadata area on the optical disc in the optical disc cartridge, and reads the corresponding data, if not, controls the optical disc library mechanical device to move the optical disc cartridge to an idle optical drive assembly, then obtains the physical address of the optical disc corresponding to the logical address from the metadata area on the optical disc, and reads the corresponding data;

[0082] After the optical drive component reads the corresponding data, it returns the read data information to the Blu-ray disc library controller. The Blu-ray disc library controller transmits the returned read data information to the instruction conversion module through the SMC / MMC protocol interface module. The instruction conversion module converts the obtained SMC / MMC standard read data information into SPC / SSC standard read data information. The SPC / SSC protocol interface module transmits the SPC / SSC standard read data information to the upper-level application server, thereby enabling the upper-level application software to complete the reading operation of the Blu-ray disc library through the operation of the virtual tape library.

[0083] Further, when the tape library data instruction is a tape write instruction, the following steps are included:

[0084] Step 20, the upper application server sends a tape data writing instruction of the SPC / SSC standard to the virtual tape library gateway server through the SPC / SSC protocol interface module, the instruction conversion module receives the tape data writing instruction of the SPC / SSC standard and converts it into a disc writing instruction of the SMC / MMC standard, the SMC / MMC protocol interface module sends the disc writing instruction of the SMC / MMC standard to the Blu-ray disc library controller, the Blu-ray disc library controller obtains the ID of the corresponding optical disc cartridge according to the disc writing instruction, queries the Blu-ray disc library, obtains the position information of the corresponding optical disc cartridge and determines whether the optical disc is located in the optical drive assembly, if so, burns the data information required to be written in the disc writing instruction into the corresponding optical disc cartridge, if not, controls the optical disc library mechanical device to move the optical disc cartridge to an idle optical drive assembly, and burns the data information required to be written in the disc writing instruction into the corresponding optical disc cartridge;

[0085] Step 21, after the optical drive component writes the corresponding data information into the corresponding optical disc, it returns the data writing completion information to the Blu-ray optical disc library controller, and the Blu-ray optical disc library controller transmits the returned data writing completion information to the instruction conversion module through the SMC / MMC protocol interface module, and the instruction conversion module converts the obtained SMC / MMC standard data writing completion information into the SPC / SSC standard data writing completion information, and the SPC / SSC protocol interface module transmits the SPC / SSC standard data writing completion information to the upper application server. This specific processing process is similar to the process of reading tape instructions, and is not described in detail here. That is, the upper application operates the manipulator / tape of the tape library that it thinks, and after the instruction conversion, it actually controls the optical drive / optical disc box of the physical optical disc library. The upper application thinks that the data is saved on a certain tape, but it is actually saved in the optical disc in the optical disc library. The data of the upper application is transmitted to the memory of the virtual tape library gateway through the network interface, and then directly burned to the optical disc in the corresponding optical disc box through the optical drive to complete the saving process. The reading process is the opposite. The virtual optical disk library gateway does not perform any operations on the data itself, and both reading and writing are instructed by the upper-level application.

[0086] Further, when the tape library data instruction is a tape loading instruction, the following steps are included: Step 30, the upper application server sends a tape loading data instruction of the SPC / SSC standard to the virtual tape library gateway server through the SPC / SSC protocol interface module, the instruction conversion module receives the tape loading data instruction of the SPC / SSC standard and converts it into a CD loading instruction of the SMC / MMC standard, the SMC / MMC protocol interface module sends the CD loading instruction of the SMC / MMC standard to the Blu-ray optical disc library controller, the Blu-ray optical disc library controller obtains the ID of the corresponding optical disc cartridge according to the CD loading instruction, queries the Blu-ray optical disc library, obtains the corresponding optical disc cartridge position information and determines whether the optical disc cartridge is located in the optical drive assembly, if so, the optical drive assembly returns the loading completion information to the Blu-ray optical disc library controller, if not, controls the optical disc library mechanical device to move the optical disc cartridge to an idle optical drive assembly, and then the optical drive assembly returns the loading completion information to the Blu-ray optical disc library controller;

[0087] Step 31, the optical drive component returns the data information of the loading completion information to the Blu-ray disc library controller, the Blu-ray disc library controller transmits the returned data information of the loading completion information to the instruction conversion module through the SMC / MMC protocol interface module, the instruction conversion module converts the obtained data information of the loading completion information of the SMC / MMC standard into the data information of the loading completion information of the SPC / SSC standard, and the SPC / SSC protocol interface module transmits the data information of the loading completion information of the SPC / SSC standard to the upper application server;

[0088] When the tape library data instruction is an instruction to unload a tape, the following steps are included:

[0089] Step 40: The upper application server sends an SPC / SSC standard tape data unloading instruction to the virtual tape library gateway server through the SPC / SSC protocol interface module; the instruction conversion module receives the SPC / SSC standard tape data unloading instruction and converts it into an SMC / MMC standard optical disk unloading instruction; the SMC / MMC protocol interface module sends the SMC / MMC standard optical disk unloading instruction to the Blu-ray optical disk library controller; the Blu-ray optical disk library controller obtains the ID of the corresponding optical disk cartridge according to the optical disk unloading instruction, queries the Blu-ray optical disk library, obtains the corresponding optical disk cartridge position information and determines whether the optical disk cartridge is located in the optical drive assembly; if so, controls the optical disk library mechanical device to move the optical disk cartridge to the corresponding position of the optical disk library, and then the optical drive assembly returns the unloading completion information to the Blu-ray optical disk library controller; if not, the optical drive assembly returns the unloading completion information to the Blu-ray optical disk library controller;

[0090] Step 41, the optical drive component returns the data information of the uninstallation completion information to the Blu-ray disc library controller, the Blu-ray disc library controller transmits the returned data information of the uninstallation completion information to the instruction conversion module through the SMC / MMC protocol interface module, the instruction conversion module converts the obtained data information of the uninstallation completion information of the SMC / MMC standard into the data information of the uninstallation completion information of the SPC / SSC standard, and the SPC / SSC protocol interface module transmits the data information of the uninstallation completion information of the SPC / SSC standard to the upper application server. This specific processing process is similar to the process of reading the tape instruction, and will not be described in detail here.

[0091] In the present application, the corresponding operating software is installed in the upper-layer application software server. After the upper-layer application software server is connected to the network, the administrator can access the gateway through the web service and use the browser to make relevant settings for the virtual tape library and the optical disk library. That is, the user can access it through the web browser, and the content includes monitoring of the operating system, monitoring of the optical disk library, virtualization settings, operation of the optical disk box, etc., and can complete all operations on the gateway and the optical disk library, including authentication, power on / off, etc.

[0092] The virtual tape library gateway system based on the Blu-ray disc library of the present invention is composed of only one Blu-ray disc library and one virtual tape library gateway server because its hardware structure is composed of one Blu-ray disc library and one virtual tape library gateway server. Among them, the Blu-ray disc library uses a Blu-ray disc cartridge as the minimum operable unit, and each disc cartridge is composed of a fixed number of Blu-ray discs. The optical discs in the disc cartridge support different RAID types to meet the requirements for security. Among them, the Blu-ray disc library also includes one or more optical drives to read and write optical disc data, and one or more mechanical devices to move / load / unload the optical disc cartridge. The virtual tape library gateway server in this application does not specifically refer to a specific type of server, which needs to include relevant interface modules connected to the optical disc library, such as Ethernet network card / fiber card / SAS card, etc., and needs to include at least one hard disk to install the operating system, Blu-ray disc library driver and virtual tape library gateway system software and related dependencies. As an entity for data storage, the Blu-ray disc library uses optical disc media to store data, and has the characteristics of security, large capacity, low maintenance, etc. The virtual tape library gateway system relies on the gateway server to virtualize the optical drive, mechanical device, and optical disc cartridge of the optical disc library into various types of tape initiators, tape library mechanical devices, and tapes for identification and use by upper-level applications.

[0093] Figure 3 The deployment method of the virtual tape library gateway system in the production environment is described. Among them, the Blu-ray disc library can be used as an auxiliary device of the virtual tape library gateway by accessing the network or directly connecting according to different scenario requirements. The virtual tape library gateway server provides all services in the network. The upper-layer application discovers the virtual device shared by HVTL (virtual tape library gateway server) through the network, and the data is transmitted to the HVTL server in the form of data stream through the network. At this time, the data is stored in the memory of the HVTL server. HVTL directly converts the received SPC and SSC instructions into SMC and MMC instructions to operate the optical disc library. The data stream will be directly transmitted to the Blu-ray disc library and burned to the optical disc, which does not occupy additional hard disk space and does not require additional IO operations. The same is true for the reading process. In addition, the interactive module of HVTL provides a management interface to the outside world, and users can monitor the status of the gateway server and the Blu-ray disc library through the browser. When necessary, specific operations can be performed on the Blu-ray disc library for maintenance operations.

[0094] like Figure 4 As shown, in this application, HVTL (virtual tape library gateway server) provides a unified Web UI interface (connected to the upper-level application software), which users can access through a browser. It can also implement the following functions: Host monitoring: Host monitoring mainly provides the runtime status of the gateway server itself, including monitoring of major indicators such as CPU, memory, hard disk, and network.

[0095] CD library monitoring: CD library monitoring mainly provides the operating status of the physical CD library managed by the gateway server, including the usage of CD magazines, alarm information of the CD library, etc.

[0096] CD library management: CD library management mainly provides general operations for physical CD libraries, including opening CD library shelves, taking out specified CD cartridges, testing CD libraries, and taking inventory.

[0097] Maintenance mode: Maintenance mode mainly provides the functions required for system failure and maintenance, including power on / off, service operation status, log download, software upgrade and other functions.

[0098] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
