TITLE:
The Disk is Dead! Long Live the Disk!
ABSTRACT:
Recent declines in RAM prices have made it reasonable to discuss replacing
disks with battery-backed RAM as the primary persistent storage medium
in desktop computers. RAM has already taken over in some areas (such as
PDAs), but disk is still the only reasonable choice for most large-scale
applications. In this talk, I will describe Conquest, a hybrid disk/RAM
filesystem that combines the best of each medium while providing a transition
path toward the day when disks can be discarded. Surprisingly, Conquest
outperforms disk-only filesystems in its disk mode, RAM-only filesystems
in its RAM mode, and cache-backed filesystems in any mode.
