System Under Test "SUT" Hardware Description:
1. Brief description of hardware
A) Name/vendor/model
B) CPU type, CPU count
C) Memory type, memory amount

2. Link to the Hardware Certification for existing system:
A) Base Certification
B) Supplemental Certification

3. List of known issues:
A) Existing BZ's
B) Existing Hardware Errata
C) Existing KBase articles

4. Memory specifications:
A) What is the expected bandwidth of the memory subsystem system wide?
(If we run many instances of memory intensive applications where
each application does not cross NUMA boundaries, how much
aggregate bandwidth might we expect on the server?)
B) Does the memory subsystem support NORMAL -vs- PERFORMANCE
mode at the management/BIOS layer? If so what is it set to?
C) How many memory channels per socket for specific CPU?
D) How many channels per socket are actually populated on the test
