Additional TPM features
The following features are supported by Intel® Xeon® E7 family processors and require a TPM to be present:
• Intel AES-NI is a processor-assisted AES encryption, supported by Intel Xeon E7 family processors, that
makes enabled encryption software faster and stronger, and offers better data protection. With this
technology, the encryption and decryption times are greatly reduced. AES-NI is enabled by default and
requires a TPM to be present.
• Intel TXT is a hardware solution, supported by Intel Xeon E7 family processors, that validates the
behavior of key software within a server at startup. The server blade will support this feature with a
future planned firmware upgrade. The server checks the hardware and software consistency behaviors
at launch time against a known good sequence. Using this verification process, the server can quickly
assess whether any attempts have been made to alter or tamper with the launch time environment. TXT
is enabled by default, and requires a TPM to be present.
