3.4.1 Serial ATA Support
The ICH10R has an integrated Serial ATA (SATA) controller that supports independent DMA
operation on six ports and supports data transfer rates of up to 3.0 Gb/s. The six SATA ports on
the workstation board are numbered SATA-0 through SATA-5. You can enable/disable the
SATA ports and/or configure them by accessing the BIOS Setup utility during POST.
3.4.1.1 Intel
®
Embedded Server RAID Technology II Support
The Intel
®
Embedded Server RAID Technology II (Intel
®
ESRTII) feature provides RAID modes
0, 1, and 10. If RAID 5 is needed with Intel
®
ESRTII, you must install the optional Intel
®
RAID
Activation Key AXXRAKSW5 accessory. You must place this activation key on the SATA
Software RAID 5 connector located on the workstation board of Intel
®
Workstation System
SC5650SCWS. For installation instructions, refer to the documentation accompanying the
workstation board and the activation key.
When Intel
®
Embedded Server RAID Technology II of the SATA controller is enabled, enclosure
management is provided through the SATA_SGPIO connector on the workstation board when a
cable is attached between this connector and the backplane or I
2
C interface.
For the locations of Intel
®
RAID Activation Key connector and SATA SGPIO connector, refer to
Figure 2. Major Board Components.
