Supports secure boot based on the chip-level Root of Trust (RoT) and provides
the level-by-level verification function starting from the hardware trusted root,
building a complete secure boot chain.
Supports the trusted platform module (TPM) and trusted password module
(TCM) to provide advanced encryption functions, such as digital signature and
remote authentication.
Meets the following requirements in NIST SP 800-147B:
– The BIOS firmware digital signature update mechanism is supported. During
the upgrade, the digital signature is verified to prevent unauthorized BIOS
firmware upgrade.
– The flash security protection mechanism is supported to prevent
unauthorized modification of the flash in the OS.
Provides 80 PLUS Platinum/Titanium PSUs with different energy efficiency
levels. The efficiency of the PSUs reaches 96% when the load is 50%.
Supports active/standby power supply and high-voltage DC power supply to
improve the efficiency of the power supply system.
Efficient Voltage Regulator Down (VRD) power supplies for boards minimize the
energy loss from DC/DC power conversion.
Area-based Proportional-Integral-Derivative (PID) intelligent fan speed
adjustment and intelligent CPU frequency scaling optimize heat dissipation and
reduce overall system power consumption.
The improved thermal design with energy-efficient fans ensures optimal heat
dissipation and reduces system power consumption.
The server is protected with power capping and power control measures.
Staggered spinup of drives reduces the server boot power consumption.
