The open Ethernet drive architecture shows for the first time how data centers can seamlessly scale-out storage infrastructures and run new and existing applications distributed directly onto hard disk drives (HDDs) and solid state drives (SSDs) for next generation big data processing, analytics, research queries and other applications that require long-term retention of active data. Mario Blandini, Sr. Director, Marketing - Cold Storage, demonstrates the capabilities in this presentation from OpenStack Summit 2014. Learn more here: http://bit.ly/1lYZa1V

Forward Looking Statement
This presentation contains forward-looking statements that involve risks and uncertainties, including, but not limited to, the development and
adoption of a new storage architecture and the potential introduction of products based on this architecture. Forward-looking statements should
not be read as a guarantee of future performance or results, and will not necessarily be accurate indications of the times at, or by, which such
performance or results will be achieved, if at all. Forward-looking statements are subject to risks and uncertainties that could cause actual
performance or results to differ materially from those expressed in or suggested by the forward-looking statements.
Additional key risks and uncertainties include the impact of continued uncertainty and volatility in global economic conditions; actions by
competitors, business conditions and growth in the various hard drive segments. More information about the other risks and uncertainties that
could affect our business are listed in our filings with the Securities and Exchange Commission (the “SEC”) and available on the SEC’s website at
www.sec.gov, including our Quarterly Report on Form 10-Q filed with the SEC on May 5, 2014, to which your attention is directed. We do not
undertake any obligation to publicly update or revise any forward-looking statement, whether as a result of new information, future developments
or otherwise, except as otherwise required by law.
This presentation contains financial measures defined as non-GAAP by the SEC. We believe that certain non-GAAP financial measures, when
presented in conjunction with comparable GAAP (Generally Accepted Accounting Principles) measures, are useful because that information is an
appropriate measure for evaluating our operating performance. Non-GAAP information is used to evaluate business performance and
management's effectiveness. These measures should be considered in addition to, not as a substitute for, or superior to, measures of financial
performance prepared in accordance with GAAP. Non-GAAP financial measures may not be calculated in the same manner by all companies
and therefore may not be comparable.

The open Ethernet drive architecture enables the migration of
“data-centric” storage services as close to storage as possible,
transforming the datacenter of the future by delivering improved
storage efficiency, flexibility, and enabling new capabilities
Goal of the Technology Demonstration:
Work with developers and operators of OpenStack cloud
software to (re)define the data center of the future
