Storage.VirtualDisk.ReadPolicy (Read or Write)

Table 1. Details of the Storage.VirtualDisk.ReadPolicy attributeThe following table provides the details of the Storage.VirtualDisk.ReadPolicy attribute.
Description The read policies indicate whether or not the controller must read sequential sectors of the virtual disk when seeking data.

NOTE: : Storage.VirtualDisk.ReadPolicy attribute is read-only for few PERCs—for example, H330.

Legal Values
  • No Read Ahead
  • Read Ahead

NOTE: : Previous generations of PERC controllers support read policy settings of No Read Ahead, Read Ahead, and Adaptive Read Ahead. With PERC 8 and PERC 9, the Read Ahead and Adaptive Read Ahead settings are functionally equivalent at the controller level. For backward compatibility purposes, some systems management interfaces and PERC 8 and 9 controllers still allow setting the read policy to Adaptive Read Ahead. While it is possible to set Read Ahead or Adaptive Read Ahead on PERC 8 or PERC 9, there is no functional difference.

Default value Adaptive
Write Privilege Server Control
License Required iDRAC Express or iDRAC Enterprise
Dependency None
