Hitachi Data Systems Introduces Hitachi Storage Cluster for Microsoft Hyper-V

Helps Customers Optimize Business Continuity and Disaster Recovery, Reduce
Business Risk and Downtime Costs

Hitachi Storage Cluster for Microsoft Hyper-V Debuts at Microsoft Tech-Ed 2009
LOS ANGELES--(Business Wire)--
Hitachi Data Systems Corporation, a wholly owned subsidiary of Hitachi, Ltd.
(NYSE:HIT) and the only provider of Services Oriented Storage Solutions, today
announced the availability of Hitachi Storage Cluster for Microsoft Hyper-V, an
innovative new business continuity and disaster recovery solution for
virtualized environments based on Windows Server 2008 Hyper-V.

The solution combines Microsoft Windows Server 2008 capabilities such as high
availability through Microsoft Multipath I/O, server virtualization and
clustering with the proven platform capabilities of Hitachi storage
virtualization and system-based replication to create a cost effective, highly
available and remotely replicated virtual server infrastructure for
organizations looking to reduce business risk and associated downtime costs.

Hitachi Storage Cluster for Microsoft Hyper-V extends Microsoft migration
capabilities to remote sites, allowing midrange to enterprise customers to
replicate and migrate virtual machines within virtualized environments either
locally or across geographically dispersed sites. The solution also features
breakthrough automated failover and data resynchronization, as well as
simplified failback of virtual machines. Additionally, organizations looking to
optimize business continuity can use the quick and live migration capabilities
of Windows Server for local protection of virtual machines.

"Customers today are looking for ways extend the benefits of virtualization and
local availability outside the data center to protect against localized outages
and widescale system failures," said Dai Vu, director of virtualization
solutions, Server and Tools Business, Microsoft Corporation. "The combination of
our proven virtualization and clustering, combined with data and replication
technologies, make this possible."

According to a recent report by Enterprise Strategy Group, an estimated 85
percent of organizations who suffer a major disaster and do not have a viable
business continuity or disaster recovery solution in place are either out of
business one year after the disaster or suffer huge financial losses. In
addition to the many benefits that server and storage virtualization can provide
separately such as consolidation, improved resource utilization, and improved
performance, Hitachi Storage Cluster for Microsoft Hyper-V can help
organizations reduce downtime and improve data availability, which have
important risk-reduction and cost savings implications.

"Today`s announcement marks another important proof point in Hitachi Data
Systems` integrated end-to-end server-to-storage virtualization strategy," said
Asim Zaheer, vice president of Product and Competitive Marketing, Hitachi Data
Systems. "As the storage virtualization leader, Hitachi Data Systems is uniquely
able to partner with industry leaders like Microsoft to bridge the gap between
server and storage infrastructures in customers' data centers. During a time
when business continuity and disaster recovery is a critical part of everyday
operations, we believe this joint solution can help organizations instantly
improve operational efficiencies and cut costs, both short and long term."
