Overall Focus Emphasize the application of Advanced Storage TechnologiesA Balanced approach to research that includes:

Applications that need/use storage Advanced and Emerging Storage Architectures Advanced and Emerging Storage Technologies both

software and hardware Business Cases and aspects of the Storage industry

Market TrendsProduct DirectionsEffects of these disruptive technologiesAdoption rates

Provide consortium members with not just technology research but a more complete and significant outcome

August 2002AO041702-3

Initial Specific FocusApplied Object-based Storage Device (OSD) Active Storage

The Application of OSD and Active Storage Devices to different real-world problems

Demonstrate the feasibility and advantages of OSD and Active Storage

Develop an understanding of the limitations of OSD and Active Storage from a theoretical and practical standpoint

How OSD Active Storage addresses real-world problems facing the storage industry today and tomorrowMust make this a Win-Win value proposition for the University and Industry

What’s in it for the UniversityProvides ample supply of focused, real-world projects and funding for Masters and PhD Thesis work

Connects students more closely with industry giving them a more complete education

Technology transfer from the University to Industry and vice versa (possibility of shared Intellectual Property)

Research projects with industrial partners can be leveraged to obtain grants for research in other areas

The DTC can act as a catalyst to bring other colleges and departments together to focus research on real-world interdisciplinary problems and issues

August 2002AO041702-7

What’s in it for the Industrial PartnersAbility to participate in more complete and significant research that is Application-driven and incorporates Storage Architectures, Technologies, and Relevant Business issues

Use of research staff and students to explore and study real-world problems and issues

Access to a pool of well-trained engineers for hiring

Access to research facilities and cost-effective students

Assistance in developing proof-of-concept technology demonstrations involving real-world problems and issues

A common ground to meet and work with other companies on pre-competitive problems and issues related to the storage industry at large

Funding leverage with other federal and state funding

What is happening?

Computing devices with large storage capacity becoming pervasive

Wireless and mobile devices becoming popular

Storage systems becoming cheaper and larger

The volume of available data becoming extremely large and hard to manage

August 2002AO041702-10

Future Computing Environment

Global Internet: reach everywhere

Pervasive Computing: include many appliances with wireless ad hoc networks

Intermittent Connectivity

Large storage capacity in each device

Data duplication is a must

Dynamically changed user demand

August 2002AO041702-11

Our Initial FocusPropose and develop the active data object concept

Based and extending the OSD (Object Storage Device) Standards

Apply the OSD and intelligent storage concept to future computing environment

Investigate applications and environments that can benefit directly

August 2002AO041702-12

An object is a logical unit of storageLives in flat name space with an IDContains data and metadata (similar to an inode)File-like methods: open, close, read, write

An OSD stores objects and could be any ofDisk drive, storage appliance, storage controller, …

OSDs enables high performance and cross platform Use the higher level abstraction we needed Offload read & write from the storage server
