Disks lie: Disks from the perspective of the filesystem

[Federico Lucifredi]

Hello Computing Performance,

  Marshall Kirk McKusick contributed this interesting piece to the ACM Queue:

Disks from the Perspective of a File System  - Disks lie. And the controllers that run them are partners in crime.

http://queue.acm.org/detail.cfm?id=2367378

  Concise and very interesting. Looks at how the underlying disk abstractions changes (Sector size, TCQ/NCQ) make an impact, positive or negative, on the filesystems laid on them - quite worth the read!

 

  Best -Federico
