Intel S5520HCT Product Specification - Page 53

Intel® Server Boards S5520HC, S5500HCV, and S5520HCT TPS Functional Architecture 3.4 ICH10R The ICH10R provides extensive I/O support. Functions and capabilities include: ƒ PCI Express* Base Specification, Revision 1.1, support ƒ PCI Local Bus Specification, Revision 2.3, support for 33-MHz PCI operations (supports up to four REQ#/GNT# pairs) ƒ ACPI Power Management Logic Support, Revision 3.0a ƒ Enhanced DMA controller, interrupt controller, and timer functions ƒ Integrated Serial ATA host controllers with independent DMA operation on up to six ports and AHCI support ƒ 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 ƒ Integrated 10/100/1000 Gigabit Ethernet MAC with System Defense ƒ System Management Bus (SMBus) Specification, Version 2.0, with additional support for I2C devices ƒ Low-Pin Count (LPC) interface support ƒ Firmware Hub (FWH) interface support ƒ 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 I2C 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 Revision 1.8 39 Intel order number E39529-013
