About the VROC SATA RAID controller
Intel Virtual RAID on CPU (VROC) is an embedded virtual RAID technology from Intel that provides
RAID capacity for systems that use SATA drives. If the RAID controller has multiple drives attached,
you can configure RAID arrays to protect data and improve read/write performance.
Features
Operating modes
The VROC SATA RAID controller supports the following operating modes:
•
AHCI mode
—This is the default mode. In this mode, all physical drives are exposed to the
operating system (OS). The drives can be directly used for data storage. Native Command
Queuing (NCQ) is supported, which improves the I/O performance of SATA drives.
•
RAID mode
—In this mode, RAID functions are enabled and RAID arrays can be created on
physical drives to improve I/O performance and data security.
NOTE:
•
For the new mode to take effect, restart the server after an operating mode change.
•
The OS might fail to start up after the operating mode of the storage controller is changed. To
resolve this issue, reinstall the OS. If the issue persists, contact Technical Support.
RAID levels
The supported RAID levels vary by storage controller model. For more information about the
supported RAID levels of each storage controller, see
H3C Servers Storage Controllers Technical

shows the minimum number of drives required by each RAID level and the maximum
number of failed drives supported by each RAID level. For more information about RAID levels, see
"Appendix B RAID arrays and fault tolerance."
