Hi DD,
Thank you for contacting Intel Technical support.
I understand that you want to know why the AES instructions (Advanced Encryption Standard) are not available for the Intel Server Board S5520UR. The AES instructions are available for Intel® Xeon® processor family and the Intel® Core™ processor family. It is supported on the Intel® CPU Xeon E5620. You can confirm this at this link: https://ark.intel.com/products/47925/Intel-Xeon-Processor-E5620-12M-Cache-2_40-GHz-5_86-GTs-Intel-QP... https://ark.intel.com/products/47925/Intel-Xeon-Processor-E5620-12M-Cache-2_40-GHz-5_86-GTs-Intel-QP..., topic: Intel® Data Protection Technology.
I'm still investigating if it is supported on server boards. I will get back to you as soon as possible with new information.
Regards,
Jeremiah A.

Hi DD,
Thank you for your quick response.
Please note that the AES-NI support is automatically enabled in the processor. Regarding the support of the Intel® AES on the Intel® Server Board S5520UR, we checked the https://www.intel.com/content/dam/support/us/en/documents/motherboards/server/s5520ur/sb/e44031012_s... Technical Product Specification for this board, and the option is not included. What it comes with is the Trusted Platform Module (TPM) feature.

Hi Intel Technical Support.
I do not use the TPM module and I do not need its support.
The processor supports AES instructions all ok .... Why are they not available from the OS, is it an OS problem or a BIOS issue?
How can I find out the reason why the instructions are not available, is there any software for testing?
All updates to Windows Server 2008 R2 are installed.
The CPU-Z utility shows the lack of availability of AES instructions for software providing why ??? Although the processor supports these instructions.

Hi DDN8,
Responding to your questions:
Why they are not available from the OS, is it an OS problem or a BIOS issue?
- The Intel® AES-IN is supported in Microsoft* Windows Server* 2008 R2.
- Microsoft* Windows Server* 2008 Release 2 have built-in support for the new instructions.
- The Intel® Server Board S5520UR, does not come with the Intel® AES feature.
How can I find out the reason why the instructions are not available, is there any software for testing?
- For support information on the Operating System you will need to contact the OS vendor directly.
