The following information outlines the controller default values in Intel® VROC, including the Intel® VROC sub-products: Intel® VROC (VMD NVMe* RAID), Intel® VROC (SATA RAID) and Intel® VROC (Non-VMD NVMe* RAID). To learn about specific features supported by each Intel® VROC sub-product, refer to the following resources:
Intel® VROC Features | The controller default values are one of the features of the Intel® VROC family of products. To learn about other features of Intel® VROC, refer to the Intel® Virtual RAID on CPU (Intel® VROC) Technical Product Specification for Windows*. |
The Intel® VROC family of products supports the ability to set or change the controller’s default parameters (that are not directly associated with an existing RAID volume) for:
These default values can be set or changed for the platform’s manufacturing environment. There are two ways to make these changes. The first method is to utilize the Intel® VROC Command Line Interface (CLI) utility, included in the Intel® VROC package, to define the default behavior. The second method is to use the Windows* registry key option.
The default behavior for the ROHI option is disabled. To change this behavior, the Intel® VROC CLI tool can be used with the following option:
The controllerName will be the name of the controller as shown when using the –I option of the command. Either --controller controllerName or --controllerMode SATA|sSATA|tSATA|VMD can be used. For example:
The following Windows* registry setting can be used as well:
The default behavior for the Read Patrol option is disabled. To change this behavior, the Intel® VROC CLI tool can be used with the following option:
The controllerName will be the name of the controller as shown when using the –I option of the command. Either --controller controllerName or --controllerMode SATA|sSATA|tSATA|VMD can be used. For example:
The following Windows* registry setting can be used as well:
Both the Read Patrol and ROHI states are stored in a registry in the same location as registry for LEDs management as ReadPatrol and RebuildOnHotInsert.
Note | Parameter changes only applies to the operating system environment and will not been seen or honored in the Pre-OS environment. The Pre-OS environment will treat these parameters as disabled. |
