The Vinum Volume Manager
is a block device
driver which implements virtual disk
drives. It isolates disk hardware from the block device
interface and maps data in ways which result in an increase in flexibility, performance and reliability compared to the traditional slice
view of disk storage. Vinum implements the RAID 0
, RAID 1
and RAID 5
models, both individually and in combination.
Primary developer is Greg "grog" Lehey, and primary (currently only) platform is FreeBSD.
