Scenario in India
are many factors driving the growth of storage. The key
ones include e-business and large enterprise applications
such as ERP, CRM, HR, for instance. Generally, a brick and
mortar company today doubles in storage needs every 12 months.
However, once they embark on e-business, they will double
their storage every 90 days, on an average.
is critical to businesses, and as such, information storage
needs to be treated with the utmost importance. Storage
can no longer be peripheral if companies are serious about
competing in the new economy. Storage is infrastructure,"
explains T. Srinivasan, country manager, EMC Computer Systems
demands will skyrocket as bandwidth increases, and the effect
of this is already being seen in India.
estimates that the information storage market will be US
$ 100 billion business by 2005.
India, most vendors are offering various kinds of storage
technologies and solutions to their customers. This broadly
falls into three types of data storage technologies. They
are Direct Access Storage (DAS), Network Attached Storage
(NAS) and Storage Area Network (SAN).
over, storage investment by customers is likely to exceed
the investment in servers in two years time. In India, corporates
need to be educated on the need to have mission critical
information online, 24x7, and the role that intelligent
storage infrastructure plays in making that happen. A few
of the large corporations have started to do this here,
and I believe that over the next few months a number of
corporations will, follow suit quickly," points out
T. Srinivasan of EMC.
users in the country today are using the storage capacity
provided by the DAS systems. But as the network data rates
are slowly exceeding the speeds and storage capacity being
offered by DAS systems, SAN and NAS systems are definitely
going to be the future for storage architecture. In fact
both Dataquest and IDC have projected explosive growth for
both SAN and NAS products. IDC has projected that NAS products
will grow fivefold to approx. $7billion by the end of 2003.
In fact, lots of vendors like EMC even see SAN and NAS to
coexist within a corporate storage infrastructure.
us look at some corporate examples. At Credit Rating Information
Services of India Ltd. (CRISIL), Sudesh Puthran, head, technology
solutions, (CRISIL) after conducting a complete study of
the storage solutions available implemented high DLT drives
in the data center. "Today we get a storage capacity
and speed of up to 1.5 Mbps. As our storage needs are increasing,
we are looking at implementing a NAS storage system. It
would be specifically to store our data for CRISIL.Com,
where it will be hosted in an Internet data center in India,"
points out Puthran.
Power India Ltd., headquartered in New Delhi, specializes
in turnkey engineering projects for the power industry.
Its activities include designing and installing power plants,
transmission and distribution systems etc., and this generates
huge amount data in the form of engineering drawings and
procurement and production data.
C R Narayanan, company IT manager, Alstom Power India Ltd.,
New Delhi, "We set about creating a separate storage
infrastructure about three years back. At that time not
many technologies were available. So we decided to deploy
tape storage system. For all centralized activities we are
using Magstar from IBM while for decentralized, it is DLT.
The engineers generally store the various versions of one
drawing in the DLTs and are sent over the 'As Built"
drawing via the WAN to be stored in the Magstar system.
We are also running a drawing management system over this
network, and that helps the engineers reduce revision and
kind of network has been built to handle the heavy load
of data that flows through it. Narayanan and his team have
designed a two-tier storage infrastructure to ensure a systematic
the headquarters the IT team has put in IBM's Magstar tape
solution including Magstar tape subsystem and Magstar Data
server. At the site office and branch office levels, the
team has put in DLT tapes from HP for storing the data.
They are also using DATs from HP to store less mission critical
data both at the headquarters and location offices.
decided on Magstar tape solution as he felt that it provided
the best combination of data rate and access time among
all the midrange and network tape storage solutions that
he had seen.
combination of fast load and fast access can extend the
use of tape drive to near on-line applications. This function
definitely extended the use of Magstar tape solution beyond
the regular save/restore operations. Most storage devices
work on a sequential basis but in Magstar maximum data read/write
integrity is accomplished with third generation magneto-resistive
heads and servo mechanisms for precision tracking, thus
reducing the time taken to store and access data,"
he adds. For storage management he used Tivoli SM solution
as again that provided him a reliable combination.
all the decentralized storage requirements, Narayanan used
DLTs as they provided a back up of as much as 80 GB of server
disk space in less than four hours. He feels that HP DLT
integrates well with Alstom's centralized storage system
and provides excellent performance, reliability and compatibility
while being easy to connect, with advanced management and
data integrity features.
Avijit Basu, business manager, Information Storage Group,
HP India, New Delhi, "Today most Indian enterprises
are using tapes for their storage requirement. In fact our
DLT Tape solutions have seen a good growth in the market.
Companies like Alstom with heavy data can definitely fulfill
their storage requirement with our high end DLT Tapes."
is OS independent and as it can work parallel to the existing
network, the LAN or WAN becomes more fast and provides more
bandwidth for larger applications," he adds.
organizations such as Alstom Power, already with a strong
storage strategy, realize the importance of storage, there
will be more and more high-end technologies such as SAN
and NAS gaining ground in the country thus leading to more
recently founded Cyquator Technologies Ltd. has set up Internet
Data Centers (IDCs) across the country to offer services
to those companies desiring to establish their presence
on the web.
the various services it offers, is storage and back up facilities
of unlimited critical data for small-to-medium-sized workgroups
in a shared environment and web-hosting services. "Data
storage is our business and hence we planned for storage
infrastructure at the initial stages and incorporated it
into the IDC design itself," points out a Cyquator
Cyquator, the debate was primarily between choosing NAS
or SAN. Since NAS and SAN are two different technologies
and deployed for different application, Cyquator finally
choose to begin with deploying NAS products.
Cyquator offers these services via the NetApp F760 box from
Network Appliances. Besides, the VERITAS Net Back up solution
along with the P1000 series based DLT tape library from
ATL has been deployed for backup. "Whether you have
a small number of users or an enterprise of thousands, the
storage system scales from 50GB to multiple terabytes to
cater to your growing capacity requirements. Thus we have
achieved virtually unlimited data storage capacity,"
points out Jitendra Israni, CTO, Cyquator Technologies Ltd.
storage explosion is just beginning to happen at Cyquator.
"In a couple of years we will invest in Storage Area
Networks (SAN), in addition to expanding our Network Attached
Storage (NAS) infrastructure," contends Israni.
begin with, Indian corporates need to understand that the
lifeline of the company lies in the storage infrastructure
and that it is a technology, which has to be considered
separately, away from servers and networks. Thus far, all
the Indian corporates were procuring storage along with
the servers, with no attention to the fact that server-based
storage is a waste of server resources. Intelligent storage
is imperative when information needs are critical. The ability
of storage to handle tasks such as backup, recovery and
disaster recovery is fundamental. If these tasks are using
server I/O, then they become a drag on the performance of
the whole system.
the first step for Indian corporates is to procure storage
infrastructure, which has been proven in heterogeneous,
multi-server environments. Storage infrastructure is a specialized
area that requires a lot of investments in the R&D,
which will determine the way this area emerges over the
next few years," explains Srinivasan of EMC.
alliance between ATL, Network Appliance, Legato, VERITAS
and Vixel has created the first and only DLT tape Storage
Area Network (SAN) backup solution that removes the inconvenience
of LAN-based backup and reduces the deployment costs when
compared to direct SCSI-attached solutions. This NetAPP-Certified
alliance of products ensures the easy and cost effectively
backup of a growing number of NetAPP filers with no impact
on LAN or application performance.
Another storage focused company with expertise in end-to-end
storage management solutions is Bangalore-based Apara Design
Automation (P) Ltd.

Alteon, VERITAS, Quantum/ALT and so on to offer end-to-end
storage solutions. Apara's customers in India include Yahoo,
Satyam, Airtel, Ericsson, Motorola, Baan, Pentamedia, Asian
Paints, Caltiger, Bplnet and many more.
Network Appliance a leader in data management, has installed
thousands of enterprise data management and web-caching
solutions worldwide. Netapp filers from Network Appliance
consolidates Unix, Windows and web data across global locations,
thus reducing data and storage management complexity. (NetAPP)
filers provide flexible and highly available Network Attached
Storage (NAS) solutions that have been widely adopted in
heterogeneous Windows NT/2000 and Unix enterprise environments.
The massive growth of data stored in NetAPP filers has lead
to serious backup complications including insufficient backup
windows and obtrusive LAN traffic during backups
The NetCache appliance from Network Appliance is a high
performance caching solution that transparently mirrors
content closer to the end user which reduces redundant traffic
and eliminates network and server bottlenecks.
filers handle storage and content management, providing
ease of use, scalability while in service, and uptime, all
with a tight cap on the total cost of ownership, Net cache
appliances handle stream serving problems, providing the
same advantage as filers while adding the ability to share
streaming bandwidth across major internet streaming protocols.
