The purpose of this project is to plan and set up information infrastructure required for co-construction of facilities by the Ministry of Environment and Resources and its subordinate units. Also, by virtual remote offsite data backup and data storage through the geographic information systems and other service systems employed by the Environmental Protection Administration Executive Yuan (R.O.C.), the subordinate units may share the facilities and resources co-constructed, promote energy conservation and carbon reduction, and set up standard operating procedures.
To reach this end, two sets of storage facilities were purchased and allocated in Taipei and Taichung for data synchronization through the copying mechanism of the storage facilities. About 40 systems in use at the EPA are transferred to the mechanism to remote backup the synchronized data through the router leased line so as to activate the remote-controlled initiation system in case of emergency and provide convenient services to all. In terms of backup data applications, the virtual tape library appliances are introduced to convert large hard disc spaces into tape read and write. And through backup software management, the data is directly written into the tape drive by the virtual tape library appliances (i.e. D2D2T backup framework). The time for complete backup is then reduced by two thirds from 61 to 19 hours.
With regard to system virtualization, the power, space, and equipment costs of the 19 machines are cut down by distributing the 26 physical machines on the 7 virtual machines. The virtualization tool is a piece of software capable of executing multiple operating systems whereby resources on the 7 virtual machines are integrated and equally distributed by dynamic assignment and through software resource distribution and management. Under abnormal circumstances, the location of the physical machine where the virtual machines are located can be adjusted where needed to enhance the system usability. Besides energy conservation and lowered machine costs, less manpower is needed to install operating systems to ensure management timeliness and operational flexibility.
As the remote offsite data backup facilities are unmanned, unmanned remote facilities management tools were also introduced during the project planning and setup. Other than the remote operating systems, the light signals and machine restart were also inspected to minimize the manpower requirement for the offsite data backup facilities in order to yield the benefits of dual facilities without having to pay for extra repair and manpower costs.
