There are two modes in which a raw deejay can be mapped for use by a basic machine
Basic mode
The mapped deejay is presented as if it is a analytic volume, or a basic deejay file, to the bedfellow operating arrangement and its absolute accouterments characteristics are hidden. In this mode, book locking provides abstracts aegis through abreast for circumstantial updates; the archetype on address operation enables snapshots. Basic approach additionally offers portability beyond accumulator accouterments because it presents the constant behavior as a basic deejay file.Concrete mode
In this mode, additionally alleged the canyon through mode, the Basic Machine Monitor bypasses the I/O virtualization band and passes all I/O commands anon to the device. All concrete characteristics of the basal accouterments are apparent to the bedfellow operating system. There is no book locking to accommodate abstracts protection.
