Dimitris Skourtis

Researcher at Almaden Research Center, ex-VMware

Biography

I am a Research Staff Member in the Storage Systems Research group at IBM Research in Almaden. Prior to that I worked on resource management and scheduling at VMware. In 2014, I completed my Ph.D. focusing on flash storage and predictable performance. I was a member of the Systems Research Lab at the Department of Computer Science, University of California, Santa Cruz. Prior to my Ph.D. studies, in 2008, I received a Master in Mathematics (M.Math) from the University of St. Andrews in Scotland.

My current research is around data storage and management with an emphasis on cloud-native environments.

Selected Publications

Flash on Rails: Consistent Flash Performance through Redundancy

Rails is a design based on redundancy, which provides predictable performance and low latency for reads under read/write workloads by physically separating reads from writes.

Erasure Coding & Read/Write Separation in Flash Storage

In this work we consider the applicability of erasure coding in Rails and consider the effects of computation due to encoding/decoding on the raw performance, as well as its effect on performance consistency.
