Intel® Server Boards S5520HC and S5500HCV TPS

Revision

Intel order number E39529-009

3.13 ACPI Support

The Intel

Server Boards S5520HC and S5500HCV support S0, S1, and S5 states. S1 is

considered a sleep state.

The Intel

Server Boards S5520HC and S5500HCV can wake up from S1 state using the USB

devices in addition to the sources described in the following paragraph.

The wake-up sources are enabled by the ACPI operating systems with cooperation from the
drivers; the BIOS has no direct control over the wake-up sources when an ACPI operating
system is loaded. The role of the BIOS is limited to describing the wake-up sources to the
operating system.

The S5 state is equivalent to the operating system shutdown. No system context is saved when
going into S5.

Virtualization Technology

Intel

Virtualization Technology is designed to support multiple software environments sharing

the same hardware resources. Each software environment may consist of an operating system
and applications. You can enable or disable the Intel

Virtualization Technology in the BIOS

Setup. The default behavior is disabled.

Note:

After changing the Intel

Virtualization Technology option (disable or enable) in the BIOS

setup, users must perform an AC power cycle before the change takes effect.

3.14.1 Intel

Virtualization Technology for Directed IO (VT-d)

The Intel

Server Boards S5520HC and S5500HCV support DMA remapping from inbound PCI

Express* memory Guest Physical Address (GPA) to Host Physical Address (HPA). PCI devices
are directly assigned to a virtual machine leading to a robust and efficient virtualization.

You can enable or disable the Intel

Virtualization Technology for Directed I/O in the BIOS

Setup. The default behavior is disabled.

Note:

After changing the Intel

Virtualization Technology for Directed I/O options (disable or

enable) in the BIOS setup, users must perform an AC power cycle before the changes can take
effect.

I/O Acceleration Technology

The Intel

Server Boards S5520HC and S5500HCV support Intel

I/O Acceleration Technology

by default. The supported Intel

I/O Acceleration Technology version varies with the network

interface card controllers that attached to the server board, Intel

I/O Acceleration Technology

version 2 (IOAT-2) is supported with onboard Intel

82575EB NICs.
