Hardware 2.3.5.3 Intel® RAID Controller SRCSAS18E SAS Connectors ® The Intel RAID Controller SRCSAS18E provides two SSF8484 SAS/SATA signal connectors. Each SSF8484 connector provides support for four SAS/SATA ports. Sideband signals are not used with this controller. Figure 4. SAS Connectors Revision 1.
Intel® RAID Controller SRCSAS18E Hardware Signal names are with respect to the host, the device connected to the host reverses the signal names. Transmit pins connect to receive pins on the other device. The SAS/SATA connector is keyed at pin 1. These pin-outs for the serial ATA connector are not compatible with the legacy PATA connector.

Intel® RAID Controller SRCSAS18E 2.7.2 Hardware SAS Expander Support The RAID Controller SRCSAS18E supports LSI Logic* expanders and Vitesse* SAS expanders that are used as a component in Intel enclosures. Other expanders may be supported post launch, based on market conditions and customer requirements. 2.7.
Software Intel® RAID Controller SRCSAS18E 3. Software 3.1 Software Architecture Overfiew The software stack described below is referred to as the SAS Software Stack and is planned for use with the current SAS RAID controllers and future RAID controllers that are compatible with SAS and SATA technology. This software stack includes software pieces used in RAID controller firmware, RAID controller BIOS, and RAID controller drivers and utilities.
Intel® RAID Controller SRCSAS18E 3.1.1 Common Layers 3.1.1.1 Firmware Software 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.
Software 3.1.1.3 Intel® RAID Controller SRCSAS18E Operating System Driver The operating system driver is the specific driver that communicates between the host resident application and the RAID controller using specific communications protocol. 3.1.2 User Interface 3.1.2.1 Intel® RAID BIOS Console 2 Configuration Utility The Intel® RAID BIOS Console 2 Configuration utility is an X-ROM based utility that can be accessed by pressing the +>G> keys during POST.
Intel® RAID Controller SRCSAS18E Software Intel® RAID Web Console 2 3.1.2.2 The Intel® RAID Web Console 2 utility runs within the operating system. It is Java* GUI-based and enables the user to easily configure the RAID controller, disk drives, battery backup module, and other storage related devices connected to the RAID controller or embedded on the server board.
Software 3.1.3 Intel® RAID Controller SRCSAS18E Command Line Utility The Command Line Utility (CLU) is an operating system based text utility that allows the configuration of the RAID controller properties, configuration of disk arrays and virtual drives, configuration of cache settings, firmware update, and error reporting. The CLU is available for DOS, Windows*, and Linux operating systems. For a list of all command line options see the Command-Line User Guide.
Intel® RAID Controller SRCSAS18E RAID Functionality and Features 4. RAID Functionality and Features 4.1 Hierarcy A 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.
RAID Functionality and Features 4.1.2 Intel® RAID Controller SRCSAS18E RAID Virtual Drive Status Table 11. RAID Virtual Drive Status Drive State Optimal Code Optimal Description The drive operating system is good. All configured drives are online. Degraded Degraded The drive operating condition is not optimal because on of the configured drives has failed or is offline. Offline Offline The drive is not available to the operating system and is unusable. 4.1.
Intel® RAID Controller SRCSAS18E 4.3 RAID Functionality and Features RAID Features 4.3.1 RAID Level Support The following RAID levels are supported on the Intel® RAID Controller SRCSAS18E. Table 12. RAID Levels RAID Level RAID 0 Description 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 Functionality and Features Intel® RAID Controller SRCSAS18E It may be unwise to enable some cache policies if a battery is not installed on the RAID controller. Drive cache is managed through a user configurable RAID controller option. However, the RAID controller battery does not protect data in drive cache in the event of a power interruption. Caution should be exercized in enabling drive cache. Table 13.
Intel® RAID Controller SRCSAS18E 4.3.5 RAID Functionality and Features Hot-Plug Drive Support Hot plug support allows hard disk drives to be insterted or removed from an enclosure without rebooting the system, as long as both the hard disk drive and server system backplane support hard drive hot plug functions. The RAID controller will immediately recognize that a drive is removed and will put it into a virtual status of “Missing” until an I/O to the drive fails.
RAID Functionality and Features 4.3.11 Intel® RAID Controller SRCSAS18E RAID Level Migration RAID level migration allows for the migration of one raid level to another. Raid level migration may require the addition of additional physical drives as part of the process. RAID level migration is an option in BIOS Console 2 utility, RAID Web Console 2 utility, or Command Line utility. 4.4 Operating Certifications Microsoft Windows* Winqual certification (WHQL). 4.5 4.5.
