that supports eight Serial ATA ports. It supports a remote intelligent
Battery Backup Unit (LSIiBBU01) only.
The MegaRAID SATA 300 PCI-X boards use an Intel 80331 chip, while
the MegaRAID SATA 300 PCI Express boards use an Intel 80333 chip.
The Intel processors provides the intelligent RAID management
capabilities. The 4-port SATA 300 adapters support RAID levels 0, 1, 5,
and 10. The 8-port SATA 300 adapters support RAID levels 0, 1, 5, 10,
and 50.
1.1.3 Enclosure Management
MegaRAID SATA 300 RAID controllers offer enclosure management
using the same protocols as SCSI Accessed Fault-Tolerant Enclosures
(SAF-TE). These protocols use an I
2
C interface to communicate with the
SEP. This feature allows you to use RAID capabilities provided by the
SATA 300 storage adapters in an enclosure containing your physical
drives.
The SATA 300 controllers use the SAF-TE command protocol to
communicate control and status with the SEP. The SAF-TE protocol
defined in the SATA II specification communicates or performs SAF-TE
operations, such as setting the drive state and turning the LED on or off
with the SEP device. SEP is a microcontroller that resides on SATA
backplane. It senses the drive inserted status, drive activity LED, and
status LED near each physical drive slot. The drive status is reported and
LED control performed according to commands through I
2
C bus. LEDs
are located on the backplane near each physical drive slot.
1.1.4 Operating System Support
The MegaRAID Serial ATA storage adapters support several major
operating systems. LSI Logic provides device drivers and RAID
management tools for operating systems on the MegaRAID Universal
Software Suite CD, which accompanies the SATA boards.
You can view the supported operating systems and download the latest
drivers for RAID storage adapters on the LSI Logic web site at
