Raid Controller SRCS28X User Manual
Introduction
2.1.1 Adapter Description
The Intel
®
Raid Controller SRCS28X is a half-size storage adapter (6.875” x 4.2”) that provides
support for eight Serial ATA ports. You can attach a daughtercard to provide battery backup
support.
The Intel
®
Raid Controller SRCS28X uses an Intel 80331 I/O Processor to support the Serial ATA
ports. The Intel 80331 I/O Processor provides the intelligent RAID management capabilities. The
Intel
®
Raid Controller SRCS28X supports RAID 0, 1, 5, 10, and 50.
2.1.2 Enclosure Management
In addition, the Intel
®
Raid Controller SRCS28X offers enclosure management through the same
protocols used for SCSI Accessed Fault-Tolerant Enclosures (SAF-TE), using an I
2
C interface to
communicate with the storage enclosure processor (SEP). This feature allows you to use RAID
capabilities provided by the Intel
®
Raid Controller SRCS28X in an enclosure containing your hard
drives.
The Intel
®
Raid Controller SRCS28X uses the SAF-TE command protocol to communicate control
and status with the storage enclosure processor (SEP). The SAF-TE protocol defined in the SATA
II specification is used to communicate or perform SAF-TE operations such as setting the drive
state and turning off/on LED with the SEP device. SEP is a micro controller resides on SATA
backplane. It senses drive inserted status, drive activity and status LEDs near each hard drive slot.
The drive status is reported and LED control performed according to commands through I2C bus.
LEDs are located on the backplane near each hard drive slot.
