COLLOQUIUM Computer Science Department, Boston University Speaker: Michael Kilian, Chief Technology Officer Centera, EMC Date: Friday, July 22 Time: 11:00 Place: Room MCS 135, 111 Cummington Street (for directions, see www.cs.bu.edu/colloquium) Title: The Opportunities of Content Addressed Storage Abstract: In the past decade, the death knell has sounded for many types of analog data. Music has largely succumbed, photos are well on their way, video and movies will complete the transition in the next 5-10 years. Telephonics is largely digital, medical imaging is almost exclusively digital, and the list continues. Anything that can be treated as information can and is being treated as digital information. In April of 2002, EMC announced Centera, the first instance of a content addressed storage (CAS) device to address these emerging markets. Unlike conventional storage devices (e.g., block or file system-based), CAS completely segregates the naming of an object from its storage location. More to the point, the content being stored actually defines the address of the object. Centera also associates metadata with every piece of data so it can be better isolated from the application that generated the object. This talk will introduce the concepts behind CAS, and particularly Centera. CAS offers many intriguing possibilities for managing the digital content that surrounds all of us. It is a storage device that can be aware of the content it is storing. Given the dramatic decrease in the cost of storage and the truly enormous (and distributed) address space with CAS, should we bother throwing anything away? How do we manage potentially trillions of things? Should we now focus on temporal views of storage or will Google become the standard way of accessing data? What happens when all of our personal information is digital and online? By the end of this talk I hope you will not only be intrigued with a new way of thinking about storage, but also challenged to think of new ways of applying a new paradigm. Biography: Michael Kilian is the CTO for the Centera division at EMC. He is responsible for product strategy including customer requirements gathering and feature design. Previous to his current role, Mike reported to the Chief Technology Officer as a Senior Technologist analyzing technology and markets of the storage industry at large. Michael built the strategy that led to the acquisition of FilePool, the company that has written the software that forms the core of the Centera platform. Michael joined EMC in the spring of 1997. Before EMC, Michael worked at Kendall Square Research and Digital Equipment Corporation. He holds a Ph.D. from Harvard University in Computer Science with a thesis on Object Oriented Programming Methodologies for Massively Parallel Computers. Centera uniquely blends objectoriented approaches to storage using a highly parallel platform. Host: Azer Bestavros
