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."

1.3 RAID-LSI-9361-8i(1G)-B RAID Card
1.3.1 Overview
The RAID-LSI-9361-8i(1G)-B RAID card adopts the PCIe 3.0 x8 interfaces and provides eight
12G-port SAS controllers. It provides powerful I/O transmission and bandwidth processing
capabilities, and supports 12LFF hard disk expansion boards and 25SFF hard disk expansion
boards, multiple disk types, SAS/SATA data channels at 6 Gbit/s and 12 Gbit/s, and multiple RAID
expansion functions to improve system performance; it supports multi-disk sharding and multi-disk
simultaneous read/write operations for data, effectively reduces disk data access delays, and
satisfies users' requirements for RAIDs in various scenarios.
1.3.2 Function
1. Supported RAID Levels
表1-4 describes the RAID levels supported by the RAID card and the corresponding number of
member disks.
表1-4 Relationship between the RAID level and the member disk quantity
RAID Level Minimum Number of Disks Maximum Number of Faulty Disks
RAID 0 1 0
RAID 1 2 1
RAID 5 3 1
RAID 6 3 (4 recommended) 2
RAID 10 4 n (n is the number of RAID 1s that make up RAID 10.)
RAID 50 6 n (n is the number of RAID 5s that make up RAID 50.)
RAID 60 6 (8 recommended) 2n (n is the number of RAID 6s that make up RAID 60.)
The RAID card supports RAID configuration through the following methods:
•Configuring RAID in UEFI boot mode (3.1.2 2. Configuring a RAID)
•Configuring RAID in Legacy boot mode (3.2.2 2. Configuring a RAID)
2. Supported Hot Spare Disks
After RAID is configured, hot spare disks are usually configured to improve data security. A hot
spare disk is a normal disk that is in standby state in the RAID system. The hot spare disk does not
contain any data. When a disk in a redundant RAID fails, the hot spare disk automatically takes
over the failed disk and rebuilds the data in the failed disk on the hot spare disk.
The RAID card supports the following two types of hot spare disks:
•Global hot spare disk: It can serve as the spare disk for all RAID groups. You can configure
one or multiple disks as the global hot spare disk(s). The global hot spare disk can
automatically replace the failed disk that appears in any RAID.

1-5
•Dedicated hot spare disk: It can serve as the spare disk for a specified RAID. You can
configure one or more dedicated hot spare disks for each RAID. The dedicated hot spare disk
can automatically replace the failed disk that appears in the specified RAID.
The RAID card supports hot spare disk configuration through the following methods:
•Configuring the hot spare disk in UEFI boot mode (3.1.2 3. Configuring a Hot Spare Disk)
•Configuring the hot spare disk in Legacy boot mode (3.2.2 3. Configuring a Hot Spare Disk)
3. Copyback
After the hot spare disk replaces the failed disk in a RAID, the data in the failed disk is rebuilt into
the hot spare disk. When the RAID card detects that the failed disk is replaced by a new disk, data
is copied from the hot spare disk back to the new disk. After the copy is completed, the hot spare
disk returns to the hot standby state. The copyback function is often used for array creation and
array repair.
4. RAID Level Migration
When the existing RAID configuration does not meet the requirements, the RAID level can be
modified without affecting the data integrity.
RAID cards support the migration of the following RAID levels:
•RAID 0 to RAID 1, RAID 5, and RAID 6
•RAID 1 to RAID 0, RAID 5, and RAID 6
•RAID 5 to RAID 0, RAID 1, and RAID 6
•RAID 6 to RAID 0, RAID 1, and RAID 5
表1-5 describes the minimum disk requirements for RAID level migration.
表1-5 Disk quantity description for RAID level migration
RAID Level Migration Mode Minimum Number of Original
Disks Number of Additional Disks Required
RAID 0 to RAID 1, RAID 5, or RAID 6 2 1
RAID 1 to RAID 0, RAID 5, or RAID 6 2 1
RAID 5 to RAID 0 or RAID 6 3 1
RAID 6 to RAID 0 or RAID 5 3 1
The RAID card supports RAID level migration through the following methods:
•Migrating the RAID level in UEFI boot mode (3.1.2 9. RAID Level Migration)
5. Expanding the RAID Capacity
When the existing RAID capacity does not meet the requirements, the RAID card can expand the
RAID capacity by increasing the available space.
The RAID card supports RAID capacity expansion through the following methods:
•Expanding the RAID capacity in UEFI boot mode (3.1.2 8. Expanding the RAID Capacity)
•Expanding the RAID capacity in Legacy boot mode (3.2.2 7. Expanding the RAID Capacity)

1-6
6. Switching the Disk Mode
The RAID card supports switching between the two disk modes shown in 表1-6.
表1-6 Disk modes supported by the RAID card for switching
Disk Mode Description
Unconfigured Good (in UEFI boot mode) or UG
(in Legacy boot mode) The physical disk is normal and can be used to configure as a RAID or hot spare disk.
Unconfigured Bad (in UEFI boot mode) or
Failed (in Legacy boot mode) The physical disk has residual RAID information and must be manually cleared.
The RAID card supports switching the disk modes through the following methods:
•Switching the disk modes in UEFI boot mode (3.1.2 1. Switching the Disk Mode)
•Switching the disk modes in Legacy boot mode (3.2.2 1. Switching the Disk Mode)
7. Clearing the Residual RAID Information on the Disk
After a RAID member disk is hot-plugged, there is residual RAID information on the disk. In this
case, you need to clear the information to reconfigure the RAID.
The RAID card supports clearing the residual RAID information on the disk through the following
methods:
•Clearing the RAID information in the disk in UEFI boot mode (3.1.2 10. Clearing the Residual
RAID Information on the Disk)
•Clearing the RAID information in the disk in Legacy boot mode (3.2.2 8. Clearing the
Residual RAID Information on the Disk)
8. Initializing the Logical Disk
After the RAID card is configured with a RAID, the RAID needs to be initialized so that it can be
used by the operating system, and the data relationships among the member disks in the
redundant RAID can meet the corresponding RAID level requirements.
The RAID card supports RAID initialization through the following methods:
•Fast Initialize Drive: The first 8 MB and the tail 8MB spaces of the RAID are initialized for
writing data, and the rest of the space is initialized on the back end.
•Slow Initialize Drive: All space in the RAID is initialized and data can be written after the
initialization is complete.
The RAID card supports disk initialization through the following methods:
•Initializing the disk in UEFI boot mode (3.1.2 5. Initializing the Logical Disk)
•Initializing the disk in Legacy boot mode (3.2.2 5. Initializing the Logical Disk)
9. Erasing Data from the Disk
To ensure the security of user data, you can completely erase the data on the disk and make it
unrecoverable. This operation usually takes several hours or longer and cannot be interrupted. If
an abnormal interruption such as power failure or restart of the server during this process, the disk
may be damaged or even unusable.
The RAID card supports data erasing through the following methods:

1-7
•Erasing the data from the disk in UEFI boot mode (3.1.2 7. Erasing Data from the Disk)
•Erasing the data from the disk in Legacy boot mode (3.2.2 6. Erasing Data from the Disk)
Caution
To avoid disk failure, do not perform other operations while erasing data from a physical disk.
10. Online Upgrading the RAID Card Firmware
The RAID card supports online firmware upgrade. After the upgrade, the RAID card can be
managed and maintained better.
The RAID card supports online upgrade of the RAID card firmware through the following methods:
•Upgrading the firmware in UEFI boot mode (3.1.2 11. Online Upgrading the RAID Card
Firmware)
11. Supporting Disk Hot Plugging
The RAID card 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.
1.3.3 Configuration Method
RAID cards can be configured either through the BIOS or the operating system. For configuration
through the BIOS, no tool is required. For configuration through the operating system, you need to
install the MegaRAID Storage Manager. This document uses the configuration through the BIOS
as an example.
