1. HC2 Enterprise-Class Private Cloud Storage Overview TierraCloud Feb, 2011 v5.4 1 TierraCloud Proprietary

2. Executive Summary TierraCloud Proprietary 2 S3 APIs Massively scalable Self managing Meta-data with query Flat name space Commodity servers Fully distributed Open-source

3. Tsunami of Data Growth We are in the exponential growth phase of unstructured data Once initial use of data is over, what’s next? Initial use could be just days Choices are: Delete it Keep it online on secondary storage Move it offline to tape TierraCloud Proprietary 3

4. What is the Unsolved Problem? Current mainstream solutions (SAN, NAS, CAS or clustered file-systems) are unable to address the following three requirements at the same time: 10x lower TCO ~4.5¢/ GB/ month fully burdened Scalable to billions of objects, PB of capacity, large objects, linear performance gain Reliable TierraCloud Proprietary 4

5. Introducing Private Cloud Storage Web2.0s have revolutionized storage Standard x86 servers with sophisticated software to build extremely large, reliable storage Architecture may be called private cloud storage TCO (total-cost-of-ownership) reductions of 10x makes this so compelling that enterprises will adopt Sea-change coming to storage architectures that have been fairly stable since mid 80’s TierraCloud Proprietary 5

6. Introducing HC2 Open-Source Project TierraCloud HC2 open-source project aims to enable enterprise class private cloud storage Software only project running on x86 servers Source Code licensed under GPLv2, contains BSD licensed code from Sun’s Project Honeycomb* TierraCloud Proprietary 6 *There is no affiliation between TierraCloud and Oracle at this time.

7. HC2 Open-Source Technology TierraCloud Proprietary 7 Uses source code from Sun’s project Honeycomb State-of-the-art award winning object-store Productized over two releases Unique Differentiators 10x TCO reduction Automated data management Extreme data mobility Ability to run 3rd party storage apps

10. Buzz Around HC2 TierraCloud Proprietary 10 "TierraCloud’s software-only, hardware-agnostic HC2 open source project extends the philosophy of the OpenSolaris Honeycomb project that was launched in 2007. HC2 continues to fulfill the particular requirements of archives, such as integrity checking and immutability, and is congruent with the OAIS archival model. However, in this incarnation, the underlying media can be heterogeneous and the cells of HC2 can be geographically dispersed. Rampantly expanded ambitions for very large scale data repositories can be expected.” -- Anne MacFarland, Senior Contributing Analyst, The Clipper Group, Inc. "It has become clear that data curation will require distributed storage and application frameworks. No single institution can develop the comprehensive, necessary infrastructure to preserve and provide access to the large amount of data being generated by all disciplines ranging from the sciences to the humanities. HC2's emphasis on hardware choices, geographically distributed data and open-source software is compelling. Most institutions will be eager to experiment with private cloud storage and HC2 represents a useful option in this regard.“ -- SayeedChoudhury, Associate Dean of University Libraries, Johns Hopkins University “The rise of the Web and, more recently, the Semantic Web, has driven the rapid growth of digital libraries and archives to preserve and share the vast volumes of research and governmental data that is now being generated. The Bodleian Library already holds millions of digital objects running into hundreds of terabytes and anticipates increasing growth into the future. To effectively meet these requirements, storage needs to become smarter and more abstracted, combining scalability, resilience and low latency with a level of content-awareness. HC2 is poised to become exemplar of this approach.” -- Neil Jefferies, R&D Project, Manager, Bodleian Libraries, Oxford University “The HC2 project brings about clever cloud concepts, which open up new perspectives in data management whenever distributed processing and OAIS-compliant archiving of multi-component objects are both desired. -- Pierre-Yves Burgi, Head of ICT Unit, University of Geneva “The paradigm of cloud computing is now beginning to make its way into standard organisational practice. Here an organisation uses commodity hardware to build a single cloud of services, expandable on demand. HC2's vision represents a leap forward in storage technology in the cloud, a RAID on steroids, where your data is not just safe from disk failure but can also be geographically located providing disaster recovery. Along with load balancing, no single point of failure and storage apps services, HC2 is a technology worth watching.” -- David Tarrant, Research Fellow, University of Southampton
