My Work

I was working on Linux block I/O scheduling. We are interested in how the Linux I/O schedulers perform in the face of modern disk systems:

  • RAID, both hardware and software;
  • TCQ/NCQ-capable disk controllers;
  • Logical volumes (LVM).

My work is primarily focused on "smart" hardware.

The aim of the work is to:

  • Document the behaviour and tunable parameters of the existing Linux I/O schedulers (Noop, Deadline, Anticipatory and CFQ);
  • Evaluate, document and improve their performance in a variety of hardware and software configurations.

Results

Some micro-benchmark results are available at IoScheduling/MicroResults.
