What’s in it for the University
Provides 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 2002
AO041702-6
What’s in it for the Industrial Partners
Ability 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 realworld 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

Active Data Object based on Intelligent
Storage Concept
Intelligent Storage Consortium
David H.C. Du
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 2002
AO041702-9
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 2002
AO041702-10
Our Initial Focus
Propose 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 2002
AO041702-11
Object Storage Model
An object is a logical unit of storage
Lives in flat name space with an ID
Contains data and metadata (similar to an inode)
File-like methods: open, close, read, write
An OSD stores objects and could be any of
Disk 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
ID x123
Blocks:3,42
Length:512
Objects enable self-managed storage.
