1.2 RST Onboard Soft RAID
1.2.1 Overview
The Intel Rapid Storage Technology (RST) onboard RAID card, integrated the AHCI and RAID
programs, is mainly used for Intel chipset for disk management, disk status viewing and other
applications. The RST is embedded on the south bridge of the motherboard and provides
performance and reliability support for systems using SATA disks. When using multiple disks, you
can use the RAID technology to protect data and improve data read and write performance.
The Intel RST onboard RAID card supports two operating modes: AHCI mode and RAID mode.
The SATAcontroller can manage up to six disks. Note that the server can host up to five disks. For
details about the interface positions, see the user guide.
1.2.2 Function
1. Switching Between Operating Modes
The Intel RST onboard RAID card supports the following operating modes:
•AHCI mode (default): This mode supports NCQ (Local Command Queue), which increases
the read/write speed of SATA disks. The system uses physical disks directly to store data.

1-3
•Intel RST Premium mode (RAID): This mode is the disk array mode and can use multiple
disks to configure RAID to improve data read/write performance as well as data security.
2. Supported RAID Levels
The RAID levels supported by the RST onboard soft RAID include RAID 0, RAID 1, RAID 5, and
RAID 10 (for details about RAID levels, see section 6 "Disk Array and Fault Tolerance Methods").
表1-3 describes the relationship between the supported RAID levels and the number of disks in a
RAID.
表1-3 Relationship between the RAID level and the disk quantity
RAID Level Minimum Number of Disks Maximum Number of Faulty Disks
RAID 0 2 0
RAID 1 2 1
RAID 5 3 1
RAID 10 4 2
The RST onboard soft RAID supports RAID configuration through the following methods:
•Configuring RAID in UEFI boot mode (2.1.3 1. Configuring a RAID)
•Configuring RAID in Legacy boot mode (2.2.3 1. Configuring a RAID)
3. Supporting Disk Hot Plugging
The RST onboard soft RAID supports disk hot plugging. You can remove and replace the damaged
disk without shutting down the system or cutting off the power supply. This improves the timely
recovery capability, scalability, and flexibility of the server for disasters.
1.2.3 Configuration Method
The RST onboard soft RAID can be configured only through BIOS. There is no need to install any
tools for the installation through the BIOS. The BIOS supports two boot modes: UEFI and Legacy
(default). Different boot modes correspond to different RAID configuration methods. For details
about the RAID configuration methods, see 2 "Using the RST Onboard Soft RAID."
Note
•The type of all physical disks in a logical disk must be the same. For example, all disks are
SATA, HDD, or SSD disks. Mixing different types of disks in a logical disk can cause RAID
performance to be degraded due to different disk performance or even logical disk creation
failure.
•To avoid data loss in the event of a disk failure, select an appropriate RAID level when
configuring disk RAID. For details on RAID levels, see 6 "Disk Array and Fault Tolerance
Methods."
