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.
