The Storage Systems Research Center is part of the Jack Baskin School of Engineering at the University of California, Santa Cruz.

Composed of faculty from the Computer Science, Computer Engineering, and Electrical Engineering departments, our research focuses on many aspects of file and storage systems.

Recent Research Findings

A random write workload running with and without Ascar

Automatic Storage Contention Alleviation and Reduction system (Ascar) is a novel storage traffic management system for improving the bandwidth utilization and fairness of resource allocation. Ascar regulates I/O traffic from the clients using a rule based algorithm that controls the congestion window and request rates; it requires no runtime coordination between clients or with a central coordinator. Ascar produces rules in an unsupervised manner by systematically exploring the solution space of possible rule designs and evaluating the target workload under the candidate rule sets. Evaluation shows that our Ascar prototype can improve the throughput of all tested workloads – some by as much as 35%. The optimization time and controller overhead are unrelated to the scale of the system; thus, it has the potential to support millions of clients. As a pure client-side solution, Ascar needs no change to either the hardware or server software.
