Firmware Version
This property displays the version of the firmware that is currently installed on the controller.
NOTE: On some controllers, Storage Management may not be able to obtain the firmware version. In this case, Storage
Management displays Not Applicable.
Minimum Required
Firmware Version
This property displays the minimum firmware version that is required by Storage Management. This property is only displayed if the
controller firmware does not meet the minimum requirement.
The firmware and drivers listed in the Readme file refer to the minimum supported version for these controllers. Later versions of
thefirmwareanddriversarealsosupported.SeetheDell™Supportwebsiteatsupport.dell.comforthemostrecentdriverand
firmware requirements.
Driver Version
This property displays the version of the driver that is currently installed on the controller.
The 2.8.0.6085 driver install package for the PERC 3/Si, and 3/Di controllers contains the 6076 driver. For this driver, Storage
Management displays 2.8.0.6076 whereas Microsoft®Windows®Device Manager displays 2.8.0.6085.
NOTE: On some controllers, Storage Management may not be able to obtain the driver version. In this case, Storage Management
displays Not Applicable.
Minimum Required
Driver Version
This property displays the minimum driver version that is required by Storage Management. This property is only displayed if the
controller driver does not meet the minimum requirement.
The firmware and drivers listed in the Readme file refer to the minimum supported version for these controllers. Later versions of
the firmware and drivers are also supported. See the Dell Support website at support.dell.com for the most recent driver and
firmware requirements.
Number of
Connectors
This property displays the number of connectors the controller has. Each connector can be attached to physical disks or an
enclosure. Depending on the controller type, the connector can be either a SCSI channel or a SAS port.
 Rebuild Rate
The rebuild rate is the percentage of the system's resources dedicated to rebuilding a failed disk when a rebuild is necessary. See
"Set Rebuild Rate" for more information.
NOTE: Revertible Hot Spare operation will have the same rebuild rate that you set here.
BGI Rate
The background initialization (BGI) rate is the percentage of the system's resources dedicated to performing the background
initialization of a virtual disk after it is created. See "Set Background Initialization Rate" for more information.
Check Consistency
Rate
The check consistency rate is the percentage of the system's resources dedicated to performing a check consistency on a redundant
virtual disk. See "Check Consistency" for more information.
Reconstruct Rate
The reconstruct rate is the percentage of the system's resources dedicated to reconstructing a disk group after adding a physical
disk or changing the RAID level of a virtual disk residing on the disk group. See "Set Reconstruct Rate" for more information.
 Alarm State
This property displays whether the controller's alarm is enabled or disabled.
NOTE: This property is displayed only for SCSI storage controllers.
Abort check
consistency on error
This property enables you to stop the Check Consistency operation on error rather than continuing. This property is available only
on controllers that have controller firmware version 6.1 and later.
Revertible Hot Spare
This property enables the automatic copying of data from a physical disk to a hot spare (in case of predictive failure) or from a hot
spare to a physical disk (in case of replacement of a degraded disk). For more information, see "Revertible Hot Spare."
Loadbalance
This property provides the ability to automatically use both controller ports or connectors connected to the same enclosure to route
I/O requests. This property is available only on SAS controllers that have controller firmware version 6.1 and later. For more
information, see "Redundant path view."
Auto replace on
predictive failure
In case of predictive failure, this property enables the automatic copying of data from a physical disk to a hot spare. Use this
property in conjunction with the "Revertible Hot Spare" property.
Redundant path view
Indicates whether Storage Management has detected a redundant path configuration. Storage Management detects a redundant
path configuration when both controller ports are connected to the same enclosure that is in a unified mode. For more information,
see "Redundant Path Configuration."
Cache Memory Size
This property displays the size of the controller's cache memory.
Patrol Read Mode
This property displays the Patrol Read mode setting for the controller. Possible values are:
Auto — When set to Auto, a Patrol Read runs continuously on the system. When one iteration of the Patrol Read is complete, the
next Patrol Read is scheduled to start within a period of time specified by the controller. You do not have the option of manually
starting or stopping the Patrol Read in Auto mode.
Manual — When set to Manual, you can start or stop the Patrol Read process.
Disabled — This property indicates that the Patrol Read process is disabled.
For more information about Patrol Read, see:
"Set Patrol Read Mode"
"Start and Stop Patrol Read"
Patrol Read State
This property displays the current state of the Patrol Read process. Possible values are:
Ready — The Patrol Read process is enabled and will run when next scheduled or when manually initiated.
Active — The Patrol Read process is currently running.
Stopped — The Patrol Read has been stopped.
For more information about Patrol Read, see "Set Patrol Read Mode."
Patrol Read Iterations
This property displays the number of Patrol Read iterations.
For more information about Patrol Read, see "Set Patrol Read Mode."
 Cluster Mode
This property indicates whether the controller is part of a cluster configuration.
SCSI Initiator ID
This property displays the SCSI ID of a SCSI controller. The default value is usually 7. You can change the default value in the BIOS.
