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.

System Management Bus (SMBus* 2.0)
The Intel
®
C220 series chipset contains a SMBus* Host interface that allows the processor to
communicate with SMBus* slaves. This interface is compatible with most I2C devices. Special
I2C commands are implemented. The Intel
®
C220 series chipset’s SMBus* host controller
provides a mechanism for the processor to initiate communications with SMBus* peripherals
(slaves). Also, the Intel
®
C220 series chipset supports slave functionality, including the Host
Notify protocol. Hence, the host controller supports eight command protocols of the SMBus*
interface (see
System Management Bus (SMBus*) Specification, Version 2.0
): Quick Command,
Send Byte, Receive Byte, Write Byte/Word, Read Byte/Word, Process Call, Block Read/Write,
and Host Notify.
The Intel
®
C220
series chipset’s SMBus* also implements hardware-based Packet Error
Checking for data robustness and the Address Resolution Protocol (ARP) to dynamically
provide address to all SMBus* devices.

Intel
®
Virtualization Technology for Direct I/O (Intel
®
VT-d)
The Intel
®
C220 series chipset provides hardware support for implementation of Intel
®
Virtualization Technology with Directed I/O (Intel
®
VT-d). Intel
®
VT-d Technology 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.

Integrated Baseboard Management Controller (BMC) Overview
The server board utilizes the I/O controller, Graphics Controller, and Baseboard Management
features of the Emulex* Pilot-III Management Controller. The following is an overview of the
features as implemented on the server board from each embedded controller.
