The modes of operation are:
Mode Description
Disabled
Jobs=Synchronous (FIFO), Drives=Synchronous
When the setting is “disabled”, jobs are processed on a first in/first out
(FIFO) basis such that they will be kept together when placed on the
output spindle. For example, let us say two jobs of one piece each are
submitted. Job 1 is a 650 MB disc and Job 2 is a 10 MB disc. Even though
Job 2 was submitted last, it will completed before Job 1 but it will NOT be
outputted to the accept spindle until Job 1 is done.
Level 0
Jobs=Asynchronous, Drives=Synchronous (Default)
When the setting is “level 0” jobs are still started on a first in / first out
basis, but completed jobs will be outputted when they are done and
therefore discs will be mixed together on the output spindle. For example,
let us say two jobs of two pieces each are submitted. Job 1 is a 650 MB
disc and Job 2 is a 10 MB disc. Even though Job 2 was submitted last, it
will completed before Job 1 but unlike the DIASBLED mode, it will not be
held but rather immediately outputted to the accept spindle when it is
done. In processing the respective jobs, the two drives in use for each job
will function in tandem such that they will not begin to write until both
drives have become ready.
Level 1*
Jobs=Synchronous (FIFO), Drives=Asynchronous
When the setting is “Level 1”, jobs are processed on a first in/first out
(FIFO) basis such that they will be kept together when placed on the
output spindle. For example, let us say two jobs of two pieces each are
submitted. Job 1 is a 650 MB disc and Job 2 is a 10 MB disc. Even though
Job 2 was submitted last, it will completed before Job 1 but it will NOT be
outputted to the accept spindle until Job 1 is done. In processing the
respective jobs, the two drives in use for each job will function
independently of one another and begin to write as soon as they become
ready.
Level 2*
Jobs=Asynchronous (FIFO), Drives=Asynchronous
When the setting is “level 2” jobs are still started on a first in / first out
basis but completed jobs will be outputted when they are done. For
example, let us say two jobs of two pieces each are submitted. Job 1 is a
650 MB disc and Job 2 is a 10 MB disc. Even though Job 2 was submitted
last, it will completed before Job 1 but unlike the DIASBLED mode, it will
not be held but rather immediately outputted to the accept spindle when it
is done. In processing the respective jobs, the two drives in use for each
job will function independently of one another and begin to write as soon
as they become ready. In this mode, disc placement on output spindle will
be scattered.
