Title: High Performance NVM-based Storage System
***************************************
Songqing
Abstract
****************************************
High performance computing requires storage system with huge capacity,
high bandwidth, low access latency and good energy efficiency. Emerging
technologies, such as nonvolatile memories (NVMs) are playing a more and
more important role in high performance computing systems for lower power
consumption and better scalability. The use of NVMs, however, has brought
great opportunities as well as challenges to redesign the traditional
storage architecture. In this talk, the weak points of existing NVMs
including PCM, STT-RAM and RRAM will be reviewed. Then, the hardware and
software challenges for applying emerging NVMs in computer architecture
and storage system are presented and discussed. Keeping in mind these
challenges, this talk will summarize recent developments of our group in
high performance NVM-based storage system from hardware level (NVM-based
storage devices, read and write optimizations in NVM) to software level
(Object-based NVM Management, NVM-based File System and Metadata
Accelerator with NVM). Experiment results show that the advantage of NVM
is enhanced and the disadvantage is avoided by the hardware and software
we have designed.
