Operating Systems Management of MEMS-based Storage Devices
MEMS-based Storage Project Page

Microelectromechanical systems (MEMS)-based storage is an exciting new technology under development by some wonderful folks both here at CMU and elsewhere. Using minute MEMS read/write heads, data bits can be stored in and retrieved from media coated on a small movable media sled. MEMS-based storage devices promise significant performance, reliability, and power improvements when used either complimentary to or alternatively to disk drives.

In this talk, I describe a systems-level view of how MEMS-based storage devices work, comparing and contrasting how these devices and disk drives are seen by the operating system. I explore how the physical characteristics of MEMS-based storage change three aspects of operating system management--request scheduling, data placement, and failure management--and speculate on future research directions in this area.

John was recently admitted to the CMU doctoral program in computer engineering. His undergraduate years hark back to Auburn University, where the Tigers (4-0, 2-0 SEC) are currently ranked nineteenth in the nation in division I-A football. This summer his ECE softball team (the Electric Fielders) emerged victorious by clinching the division championship; this fall his interests have turned to similar dominance in racquetball and volleyball.

When not working on homework for Mor Harchol-Balter's performance analysis class, he is a devoted disciple of Greg Ganger. His interests span all things computer, especially those things relating to storage or networks (e.g., networked storage).

Word up to all his homies on the D-level crewe, yo.
