Storage.VirtualDisk.DiskCachePolicy (Read or Write)
Table 1264. Details of Storage.VirtualDisk.DiskCachePolicy attribute
Description Set the physical disk drive caching policy of all members of a Virtual Disk by enabling the Disk Cache Policy. When
this feature is enabled, the physical disk drive writes data to the physical disk drive cache before writing it to the
physical disk drive. Because it is faster to write data to the cache than to a disk, enabling this feature can improve
system performance.

Storage.VirtualDisk.ReadPolicy (Read or Write)
Table 1265. 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
