Technical Product Specification

Intel® Server Board S2600IP and Intel® Workstation Board W2600CR TPS Functional Architecture
Revision 1.4 Intel order number G34153-004 37
3.3.3 Serial ATA (SATA) Controller
The Intel
®
C602 Chipset has two integrated SATA host controllers that support independent
DMA operation on up to six ports and supports data transfer rates up to 6.0 Gb/s (600 MB/s) on
up to two ports (Port 0 and 1 Only) while all ports support rates up to 3.0 Gb/s (300 MB/s) and
up to 1.5 Gb/s (150 MB/s). The SATA controller contains two modes of operation – a legacy
mode using I/O space, and an AHCI mode using memory space. Software that uses legacy
mode will not have AHCI capabilities.
The Intel
®
C602 Chipset supports the Serial ATA Specification, Revision 3.0. The Intel
®
C602
Chipset also supports several optional sections of the Serial ATA II: Extensions to Serial ATA
1.0 Specification, Revision 1.0 (AHCI support is required for some elements).
3.3.4 Serial Attached SCSI (SAS)/SATA (SCU) Controller
The Intel
®
C602 Chipset supports up to 8 SAS ports that are compliant with SAS 2.0
Specification and all ports support rates up to 3.0 Gb/s. All 8 ports are also independently
configurable and compliant with SATA Gen2 and support data transfer rates up to 3.0 Gb/s.
SAS/SATA controller is only available on specific Intel
®
C602 Chipset SKUs with optional Intel
®
RAID C600 Upgrade key. Certain SKUs are also limited to support 4 of 8 SAS/SATA ports only.
Refer to the details below.
Note: SAS/SATA (SCU) port 0-3 is by default enabled while port 4-7 is disabled.

3.3.5 AHCI
The Intel
®
C602 Chipset provides hardware support for Advanced Host Controller Interface
(AHCI), a standardized programming interface for SATA host controllers. Platforms supporting
AHCI may take advantage of performance features. AHCI also provides usability enhancements
