Server Board S2400GP TPS Functional Architecture

Revision 1.01

Intel order number G50295-002

3.8.19 Integrated NVSRAM Controller

The C600 chipset has an integrated NVSRAM controller that supports up to 32KB external

device. The host processor can read and write data to the NVSRAM component.

3.8.20 Intel

Virtualization Technology for Direct I/O (Intel

VT-d)

The C600 chipset provides hardware support for implementation of Intel

Virtualization

Technology with Directed I/O (Intel

VT-d). Intel

VT-d consists of technology components that

support the virtualization of platforms based on Intel

Architecture Processors. Intel

VT-d

Technology enables multiple operating systems and applications to run in independent

partitions. A partition behaves like a virtual machine (VM) and provides isolation and protection

across partitions. Each partition is allocated its own subset of host physical memory.

3.8.21 JTAG Boundary-Scan

The C600 chipset adds the industry standard JTAG interface and enables Boundary-Scan in

place of the XOR chains used in previous generations of chipsets. Boundary-Scan can be used

to ensure device connectivity during the board manufacturing process. The JTAG interface

allows system manufacturers to improve efficiency by using industry available tools to test the

C600 chipset on an assembled board. Since JTAG is a serial interface, it eliminates the need to

create probe points for every pin in an XOR chain. This eases pin breakout and trace routing

and simplifies the interface between the system and a bed-of-nails tester.

3.8.22 KVM/Serial Over LAN (SOL) Function

These functions support redirection of keyboard, mouse, and text screen to a terminal window

on a remote console. The keyboard, mouse, and text redirection enables the control of the client

machine through the network without the need to be physically near that machine. Text, mouse,

and keyboard redirection allows the remote machine to control and configure the client by

entering BIOS setup. The KVM/SOL function emulates a standard PCI serial port and redirects

the data from the serial port to the management console using LAN. KVM has additional

requirements of internal graphics and SOL may be used when KVM is not supported.

3.8.23 On-board Serial Attached SCSI (SAS)/Serial ATA (SATA) Support and Options

The Intel

C602-A chipset provides storage support through two integrated controllers: AHCI

and SCU. By default the server board will support up to 10 SATA ports: Two single 6Gb/sec

SATA ports routed from the AHCI controller to the two white SATA connectors labeled “SATA_0”

and “SATA_1”, four 3Gb/sec SATA ports routed from the AHCI controller to the four black SATA

connectors labeled “SATA_2” to “SATA_5”, and four 3Gb/sec SATA ports routed from the SCU

to the SFF8087 miniSAS port labeled “SCU_0”.

Note: The miniSAS connector labeled “SCU 1” is NOT functional by default and is only enabled

with the addition of an Intel

RAID C600 Upgrade Key option supporting eight AS/SATA ports.

Standard are two embedded software RAID options using the storage ports configured from the

SCU only:
