Note: When disk space is low, click the Quick Warning icon [!]
next to the space meter to see more information.
Note: When disk capacity is low, target replication to the system
is paused (see Replication Service on page 110). In
addition, space reclamation is automatically started to free
up disk space (see Space Reclamation on page 235).
Click Show More to display additional information:
• Used Disk Space - The disk space that already holds data, including
deduplicated data, system metadata, and data not intended for
deduplication.
• Deduplicated Data - The amount of data that has been
deduplicated.
• Data Not Intended for Deduplication - The amount of data on
shares 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.
Note: Used disk space includes data that is eligible for space
reclamation. Because of this, it may appear that your system is
using more disk space than you expected. Space is only
reclaimed as needed to allow for optimal performance in the
event you need to restore your data.
