Input/Output Interfaces 5.2 SATA/eSATA Interfaces These systems provide two, three, or four serial ATA (SATA) interfaces that support tranfer rates up to 3.0 Gb/s and RAID data protection functionality. These systems can also support an external SATA (eSATA) device through an optional bracket/cable assembly. 5.2.1 SATA interface The SATA interface duplicates most of the functionality of the EIDE interface through a register interface that is equivalent to that of the legacy IDE host adapter. The PCH DO component includes Intel RAID migration technology that simplifies the migration from a single hard to a RAID0 or RAID1 dual hard drive array without requiring OS reinstallation. Intel Matrix RAID provides exceptional storage performance with increased data protection for configurations using dual drive arrays.

5.2 SATA/eSATA Interfaces
These systems provide two, three, or four serial ATA (SATA) interfaces that support tranfer rates
up to 3.0 Gb/s and RAID data protection functionality. These systems can also support an
external SATA (eSATA) device through an optional bracket/cable assembly.
5.2.1 SATA interface
The SATA interface duplicates most of the functionality of the EIDE interface through a register
interface that is equivalent to that of the legacy IDE host adapter. The PCH DO component
includes Intel RAID migration technology that simplifies the migration from a single hard to a
RAID0 or RAID1 dual hard drive array without requiring OS reinstallation. Intel Matrix RAID
provides exceptional storage performance with increased data protection for configurations using
dual drive arrays. A software solution is included that provides full management and status
reporting of the RAID array, and the BIOS ROM also supports RAID creation, naming, and
deletion of RAID arrays.
