Predictive Fail Poll Interval
field
|
The number of seconds between predictive failure polls.
During each poll, the controller examines the
Self-Monitoring Analysis and Reporting Technology (SMART) data on all physical
drives to determine if any is about to fail.
|
Rebuild Rate field
|
The rate at which the controller rebuilds degraded RAID
volumes.
This rate is shown as a percentage of the total
bandwidth available.
|
Patrol Read Rate field
|
The rate at which the controller performs a background
read of the physical drives looking for inconsistent data.
This rate is shown as a percentage of the total
bandwidth available.
|
Consistency Check Rate field
|
The rate at which the controller scans the virtual
drives looking for redundant data inconsistencies and fixing them.
This rate is shown as a percentage of the total
bandwidth available.
|
Reconstruction Rate field
|
The rate at which virtual drives are reconstructed when
the capacity or RAID level needs to be changed.
This rate is shown as a percentage of the total
bandwidth available.
|
Cache Flush Interval field
|
The number of seconds waits before flushing the cache
memory to the physical drives.
|
Max Drives To Spin Up At Once
field
|
The number of drives that can be spun up simultaneously
after the server is powered on.
|
Delay Among Spinup Groups field
|
The number of seconds to wait before the controller
spins up the next set of drives.
|
Physical Drive Coercion Mode
field
|
Whether the controller rounds the size of physical
drives down to a round number. This can be one of the following:
-
None—The controller does not
do any rounding.
-
128 MB—Drive sizes are
rounded down to the closest multiple of 128 MB.
-
1GB—Drive sizes are rounded
down to the closest multiple of 1GB.
|
Cluster Mode field
|
If this field displays
true, the drives on this
controller are shared with controllers on other servers.
|
Battery Warning field
|
If this field displays
true, missing battery warnings are
disabled.
|
ECC Bucket Leak Rate field
|
The error correcting code (ECC) single-bit error bucket
leak rate, in minutes.
With ECC, the controller increments an error counter
when it encounters a single bit error while reading from a physical drive. The
controller decrements the error counter each time the number of minutes defined
in this field passes.
If the error counter reaches a system-defined maximum,
the controller sends an event message to the system.
|
Expose Enclosure Devices field
|
If this field displays
true, enclosure devices are
visible to the host drivers.
|
Maintain PD Fail History field
|
If this field displays
true, the controller remembers
which physical drives were determined to be bad across server reboots.
|
Enable Copyback on SMART field
|
If this field displays
true, the controller copies the
contents of the drive to a spare drive if Self-Monitoring Analysis and
Reporting Technology (SMART) reports an error.
|
Enable Copyback to SSD on SMART
Error field
|
If this field displays
true, the controller copies the
contents of an SSD card to a spare card if SMART reports an error.
|
Native Command Queuing field
|
If this field displays true, Native Command Queuing
(NCQ) is disabled.
|
JBOD field
|
If this field displays
true, JBOD is enabled.
|
Enable Spin Down of Unconfigured
Drives field
|
If this field displays
true, the controller spins down
unconfigured drives.
|
Enable SSD Patrol Read field
|
If this field displays
true, the controller performs
patrol reads on SSD cards.
|
Auto Enhanced Import field
|
If this field displays
true, foreign configurations are
automatically imported when the controller boots.
