NOTE: The Minimum Required Driver Version property is not displayed for PERC 12 and later controllers.
Number of Connectors It displays the number of SAS port connectors available on the controller. Each connector can be attached to physical disks or an enclosure. On PERC 9 and later internal controllers, only one logical connector is displayed.
Rebuild Rate Rebuild rate is the percentage of resources available on a system that is dedicated to rebuild a failed disk when necessary. For more information about rebuild rate, see Setting the Rebuild Rate.
NOTE: The value for the Revertible Hot Spare operation is the same as the value set for the Rebuild Rate property.
NOTE: Using PERC12 cards that have firmware 8.8.0.0-18-26, you cannot modify the Rebuild Rate property. Therefore, to change this property using OpenManage Server Administrator 11.1.0.0, downgrade the firmware version to 8.4.0.0.18-27. However, it is recommended to use OpenManage Server Administrator 11.0.0.0 with downgraded firmware version of PERC12 cards.
BGI Rate The background initialization (BGI) rate is the percentage of resources available on a system that is dedicated to perform the background initialization of a virtual disk after it is created. For more information about BGI rate, see Setting Background Initialization Rate.
Check Consistency Rate The check consistency rate is the percentage of resources available on a system that is dedicated to perform check consistency on a redundant virtual disk. For more information, see Performing a Check Consistency.
Reconstruction Rate The reconstruction rate is the percentage of resources available on a system that is dedicated to reconstruct a disk group after adding a physical disk or changing the RAID level of a virtual disk residing on the disk group. For more information about reconstruction rate, see Setting the Reconstruction Rate.
Abort Check Consistency on Error It enables you to stop the Check Consistency operation on error. This property is available only on controllers that have controller firmware version 6.1 and later.
Allow Revertible Hot Spare and Replace Member It enables the automatic copying of data from a physical disk to a hot spare (if there is predictive failure) or from a hot spare to a physical disk (if replacement of a degraded disk). For more information, see Enabling Revertible Hot Spare.
Load Balance It provides the ability to automatically use both controller ports or connectors that are 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.
NOTE: The Load Balance property is not displayed for PERC 12 and later controllers.
Auto Replace Member on Predictive Failure It enables the automatic copying of data from a physical disk to a hot spare if there is predictive failure. Use this property with the Allow Revertible Hot Spare and Replace Member property.
Redundant path view It 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.
Encryption Capable It indicates whether the controller has the capability to support encryption. Possible values are Yes and No.
Encryption Key Present It indicates whether the controller has an encryption key established. Possible values are Yes and No.
Encryption Mode It indicates whether the controller is using Local Key Management (LKM) Secure Enterprise Key Management (SEKM) or None. For more information, see Managing the Encryption Key.
T10 Protection Information Capability It indicates whether the controller supports data integrity. Possible values are Yes and No.
NOTE: The T10 Protection Information Capability property is not displayed for PERC 12 and later controllers.
