Sage A Weil
I'm a computer science graduate student in the PhD program at the University of California at Santa Cruz. There's not much here right now:
interests
- My current work involves scalable metadata management in ginormous object-based file systems. I'm interested in large distributed systems and distributed algorithms.
- I'm also interested in machine learning and artificial intelligence, and hope to steer my research in this direction.

things for classes
- EBOFS
- EBOFS is an extent-based object file system, written for the 2.6
kernel. It's goal is to provide a simple object-based file system
interface (that is, a flat namespace whereby variably-sized objects
(files) are identified by (currently) 32-bit values. Great lengths are
taken to avoid and minimize long-term object fragmentation.

system). CS229 Winter 2004. [ pdf

you are interested and want the latest, CVS access, etc.
- Scalable Archival Data and Metadata management in Ojbect-based File
Systems. CMPS 290s Spring 2004. [ pdf ]
This is a proposed implementation strategy for snapshot-like archival
consistency points. It's written in the context of the petabyte-scale
object-based storage system being designed by the SSRC here at UC Santa Cruz.
