Computer Science Department Colloquium Series Presents:

“Can Emerging Storage Technologies Help Solving Big Data Problems?”

 Professor David Du

Qwest Chair Professor at the Computer Science and Engineering Department

 

Abstract:

Many challenges exist in current big data era. These include how to store enormous amount of data for a very long time, how to identify the relevant data from all the available data, and how to process relevant data efficiently. We intend to fully utilize the available data for making critical decisions to benefit individuals, business, and society. In this talk, we will introduce several emerging storage technologies including a new type of disk drives called Shingled Magnetic Recording (SMR) drives which has bigger capacity, an active storage device call Kinetic drive which can perform search and other functions by itself without going through servers, and Non-Volatile Memory (NVM) which blurs the boundary of memory and storage. The emerging NVM has recently generated quite a bit excitements. Due to its non-volatile property, it can be used as either main memory or storage. Flash memory-based solid state drives (SSD) have already replaced high performance hard disk drives (HDD). Other types of NVRAM like PCM, MRAM, and STT-RAM have the potential to replace DRAM as main memory.  We like to ask the following questions. Can these emerging technologies help solving big data problems? With the boundary of memory and storage becoming blurred, what are to be changed in computer architecture, operating systems and software/applications? How can we take advantages of these emerging technologies to meet some of the challenges from big data era?
