Available
Available space is the area that is available for data storage. The
Available
value is displayed as an amount and as a percentage of the
total capacity in the system.
Available space is divided into the following categories:
•
Free Space
- The disk space that can be used for new deduplicated
or non-deduplicated data.
•
Reclaimable Space
- The disk space that can be used for new
deduplicated data. If the DXi is configured with non-deduplicated
shares, the DXi will automatically compact reclaimable space to
create more free space as needed.
Note:
For optimal system performance, Quantum recommends
keeping the amount of
Available
disk space at 20% or more.
Used
Used space is the area that already holds data. The
Used
value is
displayed as an amount and as a percentage of the total capacity in the
system.
Used space is divided into the following categories:
Note:
The value for each category is displayed as an amount and as a
percentage of the total capacity in the system.
•
Deduplicated Data
- The amount of data that has been
deduplicated.
•
Data Not Intended For Deduplication
- The amount of data that
will not be deduplicated (data on shares or partitions that do not
have deduplication enabled).
•
System Metadata
- The amount of disk space used for internal
operations of the DXi, including system configuration files as well as
temporary files created during replication, space reclamation, and
healthchecks.
Data Before Reduction
The
Data Before Reduction
value represents the original, native size of
all data that has been processed by the data deduplication and
compression engines.
