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.

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
