Functional Architecture

3.13 ACPI Support

®
The Intel Server System SC5650HCBRP supports S0, S1, and S5 states. S1 is considered a
sleep state.
®
The Intel Server System SC5650HCBRP 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.
3.14 Intel 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
Setup. The default behavior is disabled.
Note: After changing the Intel
setup, users must perform an AC power cycle before the change takes effect.
3.14.1 Intel
®
The Intel Server System SC5650HCBRP supports 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
Setup. The default behavior is disabled.
Note: After changing the Intel
enable) in the BIOS setup, users must perform an AC power cycle before the changes can take
effect.
