ResearchResearch InterestsMy area of concentration currently revolves around storage systems, large-scale high-performance network storage designs, filesystem designs and optimizations, disk layouts and block reorganization techniques.Research Links ProjectsProject 5 - Active Storage Networks (ASN)This is my current project. Project 4 - Large-scale Intelligent Object-based Network Storage (LIONS) This was a research project at Data Storage Institute, which is a Government funded research agency at Singapore. I was involved in design and implementation of file system for an object-based storage system. Project 3 - Continuous Data Protection Application I was working in a team of 60 on a CDP product for an R&D services company - MindTree Consulting Pvt. Ltd., Bangalore, India. Our client was StorageTek (now Sun Microsystems). The product was basically a backup and recovery application involving journals of snapshots. Project 2 - File system optimization using block-reorganization techniques This work involved design of algorithms to enhance the disk access for I/O. The effort resulted in a unique design of using multiple I/O zones on disk based on frequency of access or on sequence of access. This work also became my thesis for Master's degree at University of Connecticut. (Ref: E44 2005 Nara). Project 1 - Trace-based analysis of file system effects on disk I/O This was my first research project at University of Connecticut. The project dealt with tracing of file systems requests at the disk level. I traced different file systems (EXT2, EXT3, ReiserFS and JFS) under different kinds of workload. Results of this work was published at SPECTS held at San Jose, CA in 2004 (Link) (Paper). A simple tool developed by me for tracing of disks can be found on Storage and Network Systems Laboratory website (dTrace). |
