Knowledge Warehouse for Library D.Thirupurasundari, S.Rajeswari and S.A.V. Satya Murty Indira Gandhi Centre for Atomic Research, Kalpakkam, 603102 Email: tripura@igcar.gov.in ABSTRACT Knowledge warehouse is where knowledge is stored. Library is termed as the knowledge repository of an organization. A library information management system aptly called knowledge warehouse. Presently every library in India is getting digitized. The digital data of books, journals and reports are stored in the knowledge warehouse as well. To enhance the library information management system to a fully developed digital library on the web with advanced search facilities and secure storage facilities, knowledge of advanced storage technology, highly available cluster technology and high performance multiprocessors are required. This article will talk about them. Key words:Storage, RAID, NAS, SAN, SMP, Parallel Processing, SMP 1. INTRODUCTION Library information management system consists of order processing, resource access, user access and accounts, books issue, image processing, and information about books, journals, magazines, CDs and etc. Many levels of access control logic are implemented. The output benefits of these different modules are delivery, user details, transactions of books and other library resources, set of policy, catalog and the utility. The data in the knowledge warehouse in leaps and bounds. In India, government has initiated digitizing its various libraries. This concept is slowly spreading and all libraries are digitizing millions of books, journals are making the databases very big. These are all controlled as distributed data bases. Order Processing Resource Access User accounts Books Issue Image Processing Information holding Delivery Utility User Transaction Policy Catalog 2. STORAGE TECHNOLOGY Digitization of Books, Journals and reports Library Information Management system The Knowledge warehouse will have data from storage of millions of book, Journals of many years and reports. This needs a highly reliable, available, and secure storage technology. Storage technology has become highly reliable. They protect the systems from component and device failures. It has become available without failure on 24x7 basis. RAID, data duplicating techniques like mirroring etc are used to protect data loss in disk storage. The threats like virus, worms attack, spam and other threats are taken care by increasing security to systems. Based on the storage technology data loading, data fetching, data archiving and data management are taking place. Redundant Array of Inexpensive Disks (RAID) concept suits almost all of today’s storage technology. This technology is implemented in the large servers. The array of disks enables the server to continue operation even while they are recovering from the failure of any single disk. The underlying technique that gives the primary benefit of RAID breaks the data into parts and writes the parts to multiple disks in a striping fashion. The technology can
ecover data when a disk fails and reconstruct the data. RAID is very fault-tolerant. Disk mirroring, Disk duplexing, Parity checking, Disk striping are some the techniques which are included in the RAID concept. RAID is implemented at six different levels of RAID 0 through RAID 5. Some RAID levels may also increase the system's I/O (read and write) performance. A Networked Attached Storage (NAS) is a device located with in a network allows more hard disk space. It is not attached with any of the server or system. Separating storage from the server reduces the file serving activity and I/O bottlenecks and increases server bandwidth. Hence CPU cycles are dedicated to handle application requests, resulting in improved client response time. During the maintenance or up-gradation of the server a NAS device still delivers the data to the user. NAS supports Multi-platform File Sharing by simultaneously supporting Windows Common Internet File System (CIFS) and Unix Network File System (NFS) as well as for Macintosh, Novell, and other operating systems. Sharing files across different OS platforms on the same network is possible on NAS. The access speed is based on the bandwidth provided by the network. The prompt access is realized by upgrading the network infrastructure to Giga bit Ethernet connectivity and supporting networking cables of type CAT6 (1000 Mbps). User User User User LAN switch NAS Storage Library Server Storage Device on the Network A Storage Area Network (SAN) interconnects different kinds of storage devices with associated server through a high speed special purpose network. The storage devices available on the network are made to look like they are available locally to the system. This allows storage resources to be shared in order to provide continuous, faster, easier access to data for the users. Multiple users are requesting a same data at a time then a single copy of data is accessible to any and all hosts via multiple paths. It provides reliable data transportation which ensures low error rate, and an ability to recover from failures. Servers and storage devices may be added in parallel of one another, and do not depend on proprietary systems. Since the interconnection is through Fiber Channel it has high bandwidth and low overhead. The fabric layer separates storage and network interface it includes proactive error detection and correction.
