Job Scheduling
HP StorageWorks mpx Manager provides multiple data migration job scheduling
options to optimize bandwidth and provide maximum usage of SAN resources. It
provides a priority-based serial scheduling feature that enables you to line up
migration jobs and execute them in serial or parallel fashion, based on available
resources.
You can schedule data migration jobs for execution in the following three ways:
 Immediate Schedule (start now)
 Delayed Schedule (start at a later time within the next 30 days)
 Serial Schedule (priority-based scheduling)
Immediate Schedule
Use the Immediate Schedule option to schedule a data migration job to instantly
start data migration. You must ensure that both the source and destination LUNs
are not being accessed by any application when this option is selected.
Delayed Schedule
Use the Delayed Schedule option to schedule a data migration job to start at a
later time. When you select this option during configuration of a migration job, you
are requested to enter the start time. This allows you to configure a migration job
during normal business hours and perform actual data migration during off peak
hours, so that the application remains down only for a short period of time and
during the off peak hours.
Configure Only
The Configure Only option enables you to configure migrations jobs without a
specified start time. With this option, you must start the migration jobs when
system downtime begins. This option is very useful when the exact downtime of
the application is not known. Use this option when you need to configure all
migration jobs without requiring any application downtime.
Serial Schedule
The Serial Schedule option is designed to provide maximum flexibility for data
migration. Even though DMS supports 256 simultaneous migration jobs, typical
array performance can be maximized by having only 4 to 8 LUNs under migration.
Serial scheduling of the job allows configuration of all 256 jobs at the same time,
while having fewer active jobs at a time.
