Technical Product Specification

Intel® RAID Controller SRCSAS18E Software

Revision 1.01

Intel order number D61769-001

3.1.1 Common Layers

3.1.1.1 Firmware

The frmware is composed of multiple software layers allowing for maximum flexibility, reuse and

maintainability. These layers are described below.

3.1.1.1.1 MFC Settings

These are default settings that are programmed at the factory and consist of two types of

settings.

 Settings that are not modifiable 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 on MFC definition and default settings is available upon request.

3.1.1.1.2 RAID BIOS

The RAID BIOS is the expansion ROM software defined in the PCI specification. It performs the

RAID controller initialization from host system memory during POST.

3.1.1.1.3 Intel

RAID BIOS Console Configuration Utility

The Intel

RAID BIOS Console Configuration utility provides a graphical user interface. It is a

full-featured monitoring and configuration utility for managing all aspects of the RAID subsystem

and many features of the RAID controller. The utility is accessed by pressing the <Ctrl>+<G>

keys during system boot time. See the Software User Guide: Intel

RAID Controller

SRCSAS18E for details about this utility.

3.1.1.1.4 RAID Firmware Engine

The RAID firmware contains the algorythms for mapping physical to virtual devices, RAID level

algorithms, data redundancy calculation algorythms, and error detection, logging, and reporting

capabilities.

3.1.1.2 API

To configure the Intel

RAID Controller SRCSAS18E, a set of interfaces known as the IOCTL

interface has been developed to allow an application to issue commands to the controller

through the driver. Commands that determine adapter properties and change the parameter

settings can be issued. The API package defines a higher level of commands and functions for

developers who want to configure the RAID adapters from their own utility. This is implemented

as a 32-bit dynamic link library (DLL) for Windows* operating systems and through a set of

binaries for other operating systems. Access to the API libraries is restricted.
