Low Space Management
As disk capacity is used and free disk space approaches low levels, the DXi4700 automatically responds as
detailed in the table below.
When the DXi4700 enters the Low Space state, space reclamation and compaction are automatically
started to free up disk space (see Space Reclamation on page 346). Space reclamation and compaction
end when the DXi4700 exits the Low Space state.
When the DXi4700 enters the Critical Reserve Space state, backup ingest is stopped, and target
replication to the system is paused. Backup ingest and target replication resume when the DXi4700 exits the
Critical Reserve Space state.
Note: The system generates a service ticket and an admin alert when it enters the Low Space,
Critical Reserve Space, and No Space states. In addition, a service ticket and an admin alert are
generated when Used Disk Space reaches 85% and 95% of total disk capacity.
