Polyester has a network which is spread across many
locations nationwide and relies heavily on the IT infrastructure
for its critical business applications. A look at the
BC solutions which aim to offer profits without breaks.

Polyester Limited is a ISO:9001:2000 company and the
largest manufacturer of polyester film in India. It
has 5000 employees and is
spread across many locations nationwide.
R.N. Bhave, President - Systems and Audit, of the company
said, "BC solutions are very vital for our organization.
Especially because the business and operations processes
rely heavily on the use of the IT infrastructure. The
network has been designed to not allow any single point
of failure. There are redundancies at every critical
level," said Bhave.
Areas of concern
The various locations of the company's network are protected
with multiple firewalls. Authentication policies have
been defined at various levels to ensure that no unauthorized
person can access the network data.
The application servers which are the heart of the operations
are kept in separate geographical locations. "In
an unlikely event of failure at one location, the operations
and functions at other locations are not affected,"
The network systems are protected from power failure
with the help of UPS systems. The UPSs allow adequate
time to backup operations before diesel generator
sets take over. Critical network devices and desktop
have individual UPS systems to insure against accidental
A standard backup procedure on tapes and other media
is followed routinely to offer data availability especially
in an event of server failure. Most backup devices are
programmed to function automatically. The backup tapes
and media are
stored offsite and in fireproof cabinets.
An extra layer of continuity solutions has been deployed
on servers which run mission-critical applications and
functions. They have redundant hot-swappable power supply
modules and disk drives. Standby servers ensure immediate
availability of LAN applications. And backup provide
continuous connectivity with the other locations.
