Use the
Type
drop-down menu to select whether the data persistence rule to use for the
for the storage domain is
Temporary
,
Permanent
or
Retired
.
Notes:
• The
Temporary
setting cannot be used for a storage domain that targets a tape
library.
• When importing data, a
Temporary
persistence rule does not trigger copying
data to a disk pool unless the data is staged with IOM (Intelligent Object
Management) active and running. See
Configure the Spectra S3 Service on
for information on configuring IOM.
6.
Use the
Isolation Level
drop-down menu to select the level of physical isolation required
for the storage domain.
•
Standard
— This allows data from different buckets to reside on the same physical
media, and may provide increased performance. This setting is recommended data
policies configured to use disk storage.
•
Bucket Isolated
— Data from different buckets cannot be mixed on the same physical
storage media. This setting is recommended data policies configured to use tape
storage.
Notes:
• The
Standard
isolation level provides the best capacity utilization and overall
performance.
•
Bucket Isolated
allocates an entire tape or pool to a bucket when needed.
Allocating an entire pool to a bucket may use up resources quickly and is not
recommended.

Minimum Days to Retain

Minimum Days to Retain
for a persistence rule targeting a storage domain

greater.
