Low Capacity Management
As disk capacity is used and free disk space approaches low levels, the
DXi8500 automatically responds in the following ways:
• The
Low Capacity
condition is activated when the amount of free
disk space is less than the following value:
[500 GB + 100 GB * (total usable capacity in TB / 10 TB)]
The
Low Capacity
condition indicator turns off when free disk
space is larger than this threshold.
• An administrative alert and a service ticket are generated each time
free disk space drops below one of the following threshold values:
•
[500 GB + 100 GB * (total usable capacity in TB / 10 TB)]
-
The system banner displays
Attention
and the system enters the
Low Threshold
state. Ingest continues and space reclamation
starts.
•
250 GB
- The system banner displays
Low Space
. Ingest stops
but data can still be read.
•
10 GB
- The system banner displays
No Space
. All data read/
write is stopped.
• When the DXi8500 enters the
Low Capacity
condition, space
reclamation is automatically started to free up disk space.
A space reclamation task is initiated every 10 minutes until space
reclamation begins. Space reclamation ends when the DXi8500 exits
the
Low Capacity
condition. (Any space reclamation tasks running
at that time are allowed to complete.)
• When the DXi8500 enters the
Low Capacity
condition, target
replication to the system is paused. Target replication resumes when
the DXi8500 exits the
Low Capacity
condition.
• Ingest of backup data is not throttled during the
Low Capacity
condition unless free disk space falls below the 250 GB threshold.
When this occurs, all system I/O stops until free disk space rises
above 250 GB.
