Sify Launches On-Demand Storage Service in Partnership With Hitachi Data Systems

India's First Information Aware Storage Service

MUMBAI, India, February 17, 2010 - Sify Technologies Limited (NASDAQ Global Markets: SIFY), a
leader in consumer Internet and Enterprise services in India with global
delivery capabilities, announced today the launch of its innovative SLA
driven utility based On-Demand storage service to manage the complete
lifecycle of enterprise information, from its inception to its final
disposal. The fully managed, utility-based, On-Demand, scalable storage
platform is powered by Hitachi Data Systems.

Pradip J Nath, Executive President, "Sify's On-Demand-Storage
service provides an excellent alternative to traditional on-site, dedicated
storage systems which are mostly procured on ad-hoc basis. In today's
unpredictable business environment, IT departments most often either end up
procuring higher capacity upfront to meet unexpected demands or fall short of
capacity when the storage systems are critically needed."

He added, "The launch of our On-Demand Storage platform is a
significant step towards Sify's journey towards building India's best Cloud
Infrastructure. Sify's integrated data center, network, enterprise
applications and professional support give us the edge in offering On-Demand
'Cloud Infrastructure' for companies seeking dynamic scalability, business
agility, high-availability and enterprise security across compute, storage,
security and network platforms while reducing costs."

Vivekanand Venugopal, Vice President & GM, Hitachi Data
Systems said, "Sify's On-Demand Storage service powered by Hitachi Data
Systems solutions is certain to benefit CIOs who are tasked with aligning IT
objectives to business needs. The Hitachi cloud portfolio delivers the
industry's most integrated set of computing resources to create a single pool
of virtualized block, file and content storage to support the diverse uses
that are evolving in cloud computing today, and enables organizations to
adopt cloud services at their own pace. This perfectly complements Sify's
usage-based business model. I am delighted with the partnership and convinced
of its effectiveness to the industry."

Sify's On-Demand storage service reduces the complexities of
deploying and managing multiple storage tiers, and lowers operational costs
by automating management with flexible need-based pricing. This is combined
with Hitachi Data Systems' award-winning Hitachi Adaptable SAN Storage and
Hitachi NAS to securely virtualize IT assets into consolidated, easy to
manage pools of IT resources that can be provisioned as needed to support a
wide range of applications and data types from a single, integrated
infrastructure that is secure, reliable, scalable, cost-effective and agile
in the face of changing demands. The service also offers the industry leading
availability guarantee of 99.99% on the storage system to meet specific
application and business uptime requirements.

This service incorporates world-class best practices, ILM
strategies and tools to improve reliability, scalability, availability and
reduction of the total cost of ownership. Companies can now rely on Sify for
a unified storage pool (SAN / NAS) for their applications needs, ranging from
the most demanding database environment to secondary backup needs.
