Why we build Data Centre
Data center is a term used to descr ibe the physica l host ing of comp uterequipm ent in a shared data center environment that is mutual ly benef icial to
var ious tenants wi tho ut each in curr ing the fu l l cost o f designing, bui ld ing,
and m ainta in ing the environment .
Campus data center is designed to fu nc t ion as a hardw are faci l i ty for the
purpose of hous ing comput ing systems prov id ing var ious miss ion-cri t ica l
serv ices to the campus.
The data center is the heart of any Organization

Data Center Secure Connections
Data Center netwo rk secur i ty are custom ized to each cus tom er 's
needs. It can be a combin at ion of :
f i rewal l on network routers and sw itches,
dedicated network f i rewal ls and checkpo ints suc h as
Netscreen, Cisco Pix, Watchg uard f irewal ls,
Firewal l and ant ivirus Software on each server.
Data trans fers can be secu red by VPN, SSL, and SSH

Data Center Security
There are four levels of security for physical access to securely hostedservers and equipment in data center .
The f irst level is cod e access to the bu i lding . Everyone w il l
need a pr ivate cod e or someone with a code to assist you
to get into the bu i ld ing.
The second level is biometr ic access to the f loo r.
emplo yees or data center visi tors w il l need to pass a
biometr ic Palm scann er to gain access to Data Center.

Data Center Security
The third level is the card reader access to th e server area.
Al l access information suc h wh o and when gained access to
the server area are logged. Secur i ty manager can review
such access informat ion at anyt ime.
The fou rth level is locked cabinets for securely ho sted
servers. Keys are requ ired to open su ch lo cked cabin ets.
