Title: Power Management of Enterprise Storage Systems

Speaker: Sudhanva Gurumurthi, Penn State.

Abstract:
Data-centric services, such as transaction processing systems and
search-engines sustain the needs of millions of users each day. These
services rely heavily on the I/O subsystem for their data storage and
processing requirements. Technological improvements in hard disk drive
densities and data-rates have been key enablers in the realization of
these storage systems. However, server storage systems consume a large
amount of power, leading to higher running costs, increased stresses on
the power supply, and detrimental environmental impacts. In my talk, I
shall show that power management is a challenging problem for enterprise
storage systems and the heat that is dissipated due to the high power
consumption shall significantly restrict the ability to design higher
performance disks in the near future. I shall then present a novel disk
drive architecture called DRPM that can provide considerable savings in
energy with little loss in delivered performance. Finally, I shall show
how DRPM can be leveraged to provide a spectrum of dynamic thermal
management policies, which would pave the way for maintaining good
performance growth in future disk drives.

Bio: Sudhanva received a BE degree in Computer Science and Engineering at
the College of Engineering Guindy, Anna University. His research interests
are in storage systems, computer architecture, and fault-tolerance.
