BCNLRB is intended for:
-
creation of hardware and software system for backup information storage of the NLB and the corresponding pool of server equipment;
-
network monitoring of the main building of the National Library;
-
performing of functional control of computing and networking equipment of the main library building by checking the functioning and organization of interaction of software and hardware information tools of the new building of the National Library of Belarus and BCNLRB.
BCNLRB provides interaction between the following systems:
-
Automated Library Information System (ALIS) that provides comprehensive automation of library processes: library stock acquisition; cataloging; analytical bibliographic activity; user service; creation and storing of library stock; interlibrary subscription (ILS) and international interlibrary subscription (IILS), bibliographic information; formation and maintenance of a data storage of authoritative/regulatory records; formation and maintenance of a database of museum exhibits; regulatory information support (RIS); generating of statistical and other reports; data conversion; ALIS management;
-
Corporate information portal (Internet portal);
-
Automated library management system (ALMS) that provides comprehensive automation of the processes of planning and logging of library activities, accounting, contract management and paid services, personnel management, document flow;
-
Editorial and publishing activity, providing preparation and manufacturing of various printed and electronic products;
-
Creation of electronic copies of documents by means of electronic processing of card catalogs (retroconversion of card catalogs); electronic processing of printed documents, manuscripts, old printed and rare books, vinyl discs, audio cassettes, video cassettes, microfiches and microfilms;
-
Ensuring protection against unauthorized removal of documents;
-
Local area network administration and control.
-
Integrated retroconversion of NLB card catalogs.
BCNLRB composition:
-
server equipment and workstations;
-
network hardware;
-
software.
The backup center is geographically remote from the main data storage center and has its own server components and its own system of LAN administration and control. They duplicate (in a limited volume) the solutions applied in building of LAN administration and control system of the main center.
The backup center database servers duplicate (in a limited volume) the database servers of the main center. Limitations are applied only to the total amount of computing resources of database servers, i.e. on the total number of these servers. The limitations are caused by the fact that the capacity of the backup center should only maintain the backup data storage and be able to serve the users of the corporate information portal in the context of the information services available to them.
The data storage of the backup center completely duplicates the data storage of the main center. Both storages have built-in management tools that allow organizing and maintainance of automatically maintained data correspondence between the centers. This ensures data noncontradiction and logical consistency in both the storages.
Database servers are minimally involved in data support processes. The main tasks of database servers are providing data access, processing of data representations at a storage level and coordinated interaction in a fail-safe configuration.
Application servers of the backup center perform their functions identically to the application servers of the main center. The difference is only in the number of supported applications. The backup center does not serve the readers, however, it retains the possibility of operating with these corporate applications (first of all - ALIS). Therefore, a part of the ALIS application servers and application servers of MetaLib, SFX and IMSDB applications are operating in the backup center.
The servers of the corporate information portal of the backup center completely duplicate those of the main center. This is caused by the following:
-
the corporate portal intended to provide the necessary level and quality of information service to consumers requires the presence of existing, full-featured mirror, and the backup center serves as such a mirror;
-
the corporate information portal needs a certain system environment (proxy servers, web cache, FTP, etc.) without which the portal operation cannot be deemed safe and complete;
-
operation of the main information services of the portal (or portal mirrors) is always operating to the full extent, while integration of corporate applications into the portal is performed in relatively small volumes (search services, directories, order processing);
-
portal information services generate traffic related to database servers and comparable to, or even exceeding the traffic of corporate applications.
General purpose servers serve the office work of the backup center (file and document storage) and, if necessary, allow interaction with FTP portal server. A group of management servers is formed separately from the main data storage center, but is coordinated with it the system of LAN administration and control. Creation of such a system in the backup center is necessary, because interaction of database servers, application servers and portal servers is performed within the LAN of the backup center. However, due to the fact that there are no plans to deploy numerous workplaces of NLB employees and readers in the Backup center, the amount of server equipment in this system is reduced.
LAN administration and control system of the backup center includes (in a limited volume) management servers being the key management tools in IT infrastructure, and a group of servers that manage the LAN mainly to provide access control to servers and to other resources and global security policy control systems.
