2.1. Computer Network & Infrastructure

The Centre maintains basic infrastructural facilities such as Computer Laboratories and Data Centre to

support all its essential computing activities. Important IT infrastructural facilities available at the
Centre are as follows:

2.1.1. PCs, Laptops and Servers

The main objective of the Centre is to provide proactive help to the universities in library automation and
to mediate resource sharing amongst them. Computing and network infrastructure are the main assets
of the Centre. The Centre has added more PCs, Laptops, gadgets and other equipment with high
configuration in 2016-2017 for the staff and users with a total no. of 181 PCs and 30 laptops for scientists,

project staff, walk-in user’s facilities for researchers, training laboratories, ETD lab., etc.

The Centre earlier had four servers for hosting its services including two IBM x3500 1U servers for web
services and two IBM x3660 5U servers for its research & development activities. In addition, one HP
Blade Server Enclosure C3000 was procured from HP along with eight ProLiant BL460c servers in 2009
for different services of the Centre such as Web services, INFLIBNET website, Shodhganga, OJAS, N-

LIST, N-LIST Proxy Server, InfoPort, e-PG Pathshala, IndCat, DNS server, Intranet server, UGC website,
e-SARTS and other important services. With addition projects, schemes and increased in volume of
data, the Centre has again procured IBM Blade Centre S chassis with six blades and data storage to host
mirror sites at INFLIBNET Centre as well as at the BSNL Hosting Services. Centre also has five high-end
DELL PowerEdge R630 servers for e-Acharya, ICSSR Data Repository, Vidwan, e-PG Pathshala,

Shodhganga and UGC Website. Centre has also purchased 12TB Storage DELL PowerVault for the e-
Acharya.

During the year under report, Centre also upgraded its server in terms of storage capacity and RAM for
providing improved user experience.

2.1.2. Campus-LAN and Internet Connectivity

The Centre provides most of its services through Internet on 24*7*365 basis. The network

infrastructure is one of the most important components providing efficient and effective services to the
remote and local academic users. The Centre has upgraded network infrastructure that connects all its
offices and laboratories with National Knowledge Network (NKN) that provides 1 Gbps MPLS (Multi
Protocol Layer Switching) connectivity to all universities in India. The bandwidth is currently used within
a limit of 100-150 Mbps, but it can be increased on demand based on bandwidth intensive applications
upto 1 Gbps. INFLIBNET Centre is having two Internet connections, i.e. one from NKN and other from

BSNL for standby purpose. This gives redundancy to Internet links which is essential in an organisation
which is striving towards Tier 3 Data Centre. Access to e-resources is enabled on all sets of IP addresses
used by the Centre. STM (Synchronous Transfer Mode) equipment at Centre is connected through
Optical Fiber to Gandhinagar node of NKN on ring topology. This gives redundancy of NKN links and the

architecture of the NKN is enabled to reach all universities with minimum hops. Any university can be
