8.1.4 Intel® Virtual RAID on Chip (Intel® VROC) for SATA
By default, server board RAID options are disabled in BIOS Setup. To enable server board RAID support,
access the BIOS Setup utility during POST. The server board RAID options can be found under the
sSATA
Controller or SATA Controller options that are under the following BIOS Setup menu: Advanced > Mass
Storage Controller Configuration .
Figure 47. BIOS Setup Mass Storage Controller Configuration Screen
Note: RAID partitions created using Intel® VROC 7.5 cannot span across the two embedded SATA controllers.
Only drives attached to a common SATA controller can be included in a RAID partition.
Intel® VROC 7.5 offers several options for RAID to meet the needs of the end user. AHCI support provides
higher performance and alleviates disk bottlenecks by taking advantage of the independent DMA engines
that each SATA port offers in the PCH chipset. Supported RAID levels include 0, 1, 5, and 10.
•
RAID 0 – Uses striping to provide high data throughput, especially for large files in an environment
that does not require fault tolerance.
• RAID 1 – Uses mirroring so that data written to one disk drive simultaneously writes to another disk
drive. This action is good for small databases or other applications that require small capacity but
complete data redundancy.
• RAID 5 – Uses disk striping and parity data across all drives (distributed parity) to provide high data
throughput, especially for small random access.
• RAID 10 – A combination of RAID 0 and RAID 1, consists of striped data across mirrored spans. It
provides high data throughput and complete data redundancy but uses a larger number of spans.
