3.1 Common Layers
3.1.1 Firmware
The firmware is composed of multiple software layers, allowing for maximum flexibility, reuse,
and maintainability. These layers are described below.
3.1.1.1 MFC Settings
MFC default settings are factory programmed and consist of two types of settings:
Settings that cannot be modified in the field. These include the PCI IDs.
Settings that can be modified using a utility. These include default cache settings,
rebuild rates, and other BIOS and operational defaults. Access to the MFC modification
utility is restricted.
Additional information about MFC definitions and default settings is available upon request.
3.1.1.2 RAID BIOS
The RAID BIOS is the expansion ROM software defined in the PCI specification. It performs the
RAID controller initialization from the host system memory during POST.

is accessed by pressing the <Ctrl> + <G> keys during system boot time. For details about this
utility, see the Intel
®
RAID Software User’s Guide (Document number: D29305-00x).
3.1.1.4 RAID Firmware Engine
The RAID firmware contains the algorithms for mapping physical to virtual devices, RAID level
algorithms, data redundancy calculation algorithms, and error detection, logging, and reporting
capabilities.
3.1.2 API
To configure the Intel® Integrated RAID Module SROMBSASMR, a set of interfaces known as
the IOCTL interface is provided, which allows an application to issue commands to the
controller through the driver. Commands can be issued to determine adapter properties and
change the parameter settings. The API package defines a higher level of commands and
functions for developers who want to configure the RAID adapters with their own utility. This is
implemented as a 32-bit dynamic link library (DLL) for Microsoft Windows* operating systems
and through a set of binaries for other operating systems. Access to the API libraries is
restricted.

4. RAID Functionality and Features
4.1 Hierarchy
The fundamental purpose of a RAID system is to present a usable data storage medium (virtual
drive) with some level of redundancy to a host operating system. The Intel
®
RAID firmware is
based on the concept of associating physical drives in arrays and then creating a virtual drive
from that array that includes a functional RAID level. To create a virtual drive and present it to
the host operating system, the RAID firmware typically follows these steps:
1. One or more physical drives are selected and associated as an array.
2. One or more arrays are associated and given a RAID level. This process creates a virtual
drive and provides an option to initialize the virtual drive.
3. The RAID firmware presents the virtual drive to the operating system.

4.2 SAS Bus and ID Mapping
Devices on the SAS bus are persistently mapped based on a SAS address.
4.3 RAID Features
4.3.1 RAID Level Support
Table 12. Supported RAID Levels
RAID Level Description
RAID 0 Data is striped to one or more physical drives. If using more than one disk, each stripe is stored on the
drives in a “round robin” fashion. RAID 0 includes no redundancy. If one hard disk fails, all data is lost.
RAID 1 Disk mirroring: all data is stored twice, making each drive the image of the other. Missing data on one
drive can be recovered from data on the other drive. RAID 1 requires a minimum of two drives in the
array.
RAID 5 Data striping with parity: Data is striped across the hard disks and the controller calculates redundancy
data (parity information) that is also striped across the hard disks. Missing data is rebuilt from parity.
RAID 5 requires a minimum of three drives in the array.
RAID 6 Data striping with distributed parity across two disks: Data is striped across all disks in the array and
two parity disks are used to provide protection against the failure of up to two physical disks. In each
row of data blocks, two sets of parity data are stored.
RAID 10 RAID 10 is accomplished by striping data across two or up to eight RAID 1 arrays. Missing data is
rebuilt from redundant data stripes. RAID 10 requires a minimum of four drives. RAID 10 provides high
data throughput rates.
RAID 50 RAID 50 is accomplished by striping data across two or up to five RAID 5 arrays. Missing data is
rebuilt from redundant data stripes. RAID 50 requires a minimum of six drives. RAID 50 provides high
data throughput rates.
RAID 60 RAID 60 is accomplished by striping data across two or up to five RAID 6 arrays. Missing data is
rebuilt from redundant data stripes. RAID 60 requires a minimum of eight drives. RAID 60 provides
high fault tolerance.

4.3.2 Cache Policies
The RAID cache can temporarily store data so it can be more quickly accessed, or to await
drive readiness. The cache is available both on the RAID controller and hard drives. The RAID
controller read and write cache policy is set on a virtual drive level. This policy is set when the
virtual drive is created, but it can be changed using the Intel
configuration utility, the command-line utility, or the Intel
®
RAID BIOS Console 2
®
RAID Web Console 2 utility.
The user should not enable specific cache policies if the Intel
®
RAID Smart Battery is not
installed. The drive cache is managed through a user-configurable RAID controller option, but
the RAID controller battery does not protect data in the drive cache in the event of a power
interruption. Exercise caution when enabling the drive cache.
Table 13. Cache Policies
Array Cache Policy Cache Option Description
Cache Policy
Read Policy
Write Policy
Hard Drive Cache Read and Write Cache Memory located on the hard drive is used to cache data going to or
Direct I/O When possible, no cache is involved for both reads and writes. The
data transfers are directly from host to disk and from disk to host.
Cached I/O All reads first look at the cache. If a cache hit occurs, the data is read
from cache; if not, the data is read from disk and the read data is
buffered into cache. All writes to drive are also written to cache.
No Read Ahead The controller does not use read-ahead.
Read Ahead Specifies that additional consecutive data stripes are read and
buffered into cache.
Adaptive Read Ahead Specifies that the controller begin using read-ahead if the two most
recent disk accesses occurred in sequential sectors.
Write Through The controller sends a data transfer completion signal to the host after
the disk subsystem receives all the data in a transaction and the data
is successfully written to disk.
Write Back The controller sends a data transfer completion signal to the host
when the controller cache receives all the data in a transaction and the
data is then written to disk as the drive becomes available.
If the ‘Use Write Through for failed or missing battery’ option is
disabled, the Write Back mode is enabled even if the battery backup
unit is bad or missing.
coming from the drive. Enabling the hard drive cache can result in a
performance improvement but data held in drive cache is not protected
by the RAID controller.

4.3.3 Stripe Size
The stripe size determines the size of each data stripe on each hard drive. The options are 8,
16, 32, 64, 128, 256, 512, and 1024 KB. The stripe size is set when the virtual drive is created.
It cannot be changed without removing the virtual drive configuration and all data contained on
the virtual drive.
4.3.4 Hot-spare Drives
Hot-spare drives are designated to automatically replace a failed drive. Hot-spare drives must
be the same size or larger than the drives they will replace. They can be designated as a private
hot-spare drive assigned to one virtual drive, or they may be a global hot-spare that is assigned
to all virtual drives attached to the RAID controller. Hot-spare drives can be designated using
the Intel
®
RAID BIOS Console 2 utility, the Intel® RAID Web Console 2 utility, or the command-
line utility.
4.3.5 Hot-plug Drive Support
Hot-plug support allows hard drives to be inserted or removed without rebooting the system, as
long as both the hard drive and server system backplane support hard drive hot-plug functions.
The RAID controller immediately recognizes when a drive is removed and sets the virtual status
to “Missing” until an I/O to the drive fails. The drive status then changes to “Failed.”
A drive inserted into an attached intelligent enclosure is recognized as present. A drive inserted
into an attached non-intelligent enclosure may require a bus scan before it is detected. Hot-plug
of new drives is supported in both intelligent and non-intelligent enclosures.
4.3.6 Auto-declare Hot-spare Drive
If the RAID controller has a RAID array drive that is in a failed (degraded) state and the failed
drive is removed and a new hard drive of the same size or larger is inserted into the same slot,
the new drive is automatically marked as a hot-spare drive and a rebuild begins. A bus scan
may be required in a non-intelligent enclosure.
4.3.7 Physical Drive Roaming
Physical drive roaming allows the user to move drives to any port on the RAID controller without
losing the configuration.
4.3.8 Virtual Drive Roaming
Virtual drive roaming allows the user to move a virtual drive from one controller to another
system/controller without losing the configuration or data. All virtual drives attached to the RAID
controller must be moved as a unit.

4.3.9 RAID Controller Migration
The RAID controller migration feature allows a defective RAID controller to be removed and
replaced by a compatible RAID controller without losing the configuration or data. To avoid a
configuration mismatch, it is wise to reset the new controller configuration before attaching the
array drives. If a configuration mismatch occurs, then care must be taken to use the
configuration on the drives or all data may be lost.
4.3.10 Online Capacity Expansion
Online capacity expansion (OCE) allows additional drives to be added to a virtual drive in an
array. OCE is available as an option in the Intel
