Relion 1900e/2900e Manual
19 Revision 1.3
3.5.2.1 Intel ® Virtualization Technology (Intel ® VT) for Intel ® 64 and IA-32 Intel ® Architecture (Intel ® VT-x)
Hardware support in the core, to improve performance and robustness for virtualization. Intel VT-x
specifications and functional descriptions are included in the Intel® 64 and IA-32 Architectures Software
Developer’s Manual.
3.5.2.2 Intel
®
Virtualization Technology for Directed I/O (Intel
®
VT-d)
Hardware support in the core and uncore implementations to support and improve I/O virtualization
performance and robustness.
3.5.2.3 Intel
®
Trusted Execution Technology for servers (Intel
®
TXT)
Intel TXT defines platform-level enhancements that provide the building blocks for creating trusted
platforms. The Intel TXT platform helps to provide the authenticity of the controlling environment such that
those wishing to rely on the platform can make an appropriate trust decision. The Intel TXT platform
determines the identity of the controlling environment by accurately measuring and verifying the controlling
software.
3.5.2.4 Execute Disable Bit
Intel's Execute Disable Bit functionality can help prevent certain classes of malicious buffer overflow attacks
when combined with a supporting operating system. This allows the processor to classify areas in memory
by where application code can execute and where it cannot. When malicious code attempts to insert code in
the buffer, the processor disables code execution, preventing damage and further propagation.
3.5.2.5 Advanced Encryption Standard (AES)
These instructions enable fast and secure data encryption and decryption, using the Advanced Encryption
Standard (AES)
3.5.2.6 Intel
®
Hyper-Threading Technology
The processor supports Intel
®
Hyper-Threading Technology (Intel
®
HT Technology), which allows an
execution core to function as two logical processors. While some execution resources such as caches,
execution units, and buses are shared, each logical processor has its own architectural state with its own set
of general-purpose registers and control registers. This feature must be enabled via the BIOS and requires
operating system support.
3.5.2.7 Intel
®
Turbo Boost Technology
Intel
®
Turbo Boost Technology is a feature that allows the processor to opportunistically and automatically
run faster than its rated operating frequency if it is operating below power, temperature, and current limits.
The result is increased performance in multi-threaded and single threaded workloads. It should be enabled
in the BIOS for the processor to operate with maximum performance.
3.5.2.8 Enhanced Intel ® SpeedStep Technology
The processor supports Enhanced Intel SpeedStep Technology (EIST) as an advanced means of enabling
very high performance while also meeting the power conservation needs of the platform.
