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.

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."
Security Capable
Indicates whether the controller has the capability to support security. Possible values are Yes and No.
Security Key
Present
Indicates whether the controller has a Security Key established. Possible values are Yes and No.
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.
