TITLE

And The Hard Drive Said: 'Tell Me What To Do, Not (Exactly) How To Do It!'

ABSTRACT

A disk drive has vast amounts of internal information and intelligence that enables it to deliver high performance. Unfortunately, much of that potential goes unrealized as layers above utilize crude interfaces to interact with the disk, thus greatly limiting in-disk optimizations. In this talk, we will explore the myriad reasons for this state of affairs, and explore some new possible ways in which file systems and higher levels applications might interact with drives to enable much more streamlined, high-performance interactions.
