| Abstract | iSCSI is a protocol standardized by IETF that runs on a TCP/IP network to transfer standard SCSI commands. In this paper, we evaluate the performance of iSCSI using standard PCs running a software implementation of the protocol, with the aim of assessing the performance of low-cost distributed storage solutions. First, we compare the performance when using a local disk with those of a virtualized disk connected through a standard gigabit Ethernet LAN during file I/O operations. Then, we emulate the characteristics of a WAN/MAN setup by using a software emulator within the Linux kernel to generate delays and packet losses, and evaluate the ability of iSCSI to offer disaster recovery solutions over high-speed long-distance links. We found that, even if TCP can be tuned to support links with large bandwidth-delay products, iSCSI does not reach good performance due to its windowing scheme that is not large enough, in the used software implementation, to support long-distance links. Finally, we test the iSCSI behavior when other types of traffic share network links with the iSCSI protocol. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
