ports and AHCI support
USB host interface with support for up to 12 USB ports; six UHCI host controllers; and
two EHCI high-speed USB 2.0 host controllers
Integrated 10/100/1000 Gigabit Ethernet MAC with System Defense
System Management Bus (SMBus) Specification, Version 2.0, with additional support for
I
2
C devices
Low-Pin Count (LPC) interface support
Firmware Hub (FWH) interface support
Serial Peripheral Interface (SPI) support
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 server boards 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 Intel
®
Server Boards S5520HC, S5500HCV and
S5520HCT. For installation instructions, see the documentation accompanying the server
boards 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 server boards when a
cable is attached between this connector and the backplane or I
2
C interface.
See Figure 3, “Major Board Components” for the locations of Intel
®
RAID Activation Key
connector and SATA SGPIO connector.
Intel
®
Embedded Server RAID Technology II functionality requires the following items:
• ICH10R I/O Controller Hub
• Software RAID option is selected on the BIOS menu for the SATA controller
