Intel® Xeon Phi™ Coprocessor and Non-Intel GPGPU Add-in
Card Support
Some (not all) system configurations of the Intel® Server System R2000WF product family have thermal and
mechanical support for Intel® Xeon Phi™ coprocessor cards and non-Intel GPGPU add-in cards. The card and
system configurations that are supported depend on power and thermal limits of the system and power and
thermal requirements of the add-in card. This chapter provides an overview of the system configuration
criteria needed to support these high power cards.
Disclaimer
: Intel incorporates necessary features and conducts appropriate thermal testing of its server
systems to ensure the thermal requirements of Intel® Xeon Phi™ coprocessor cards can be supported when
the documented support criteria are met.
Intel can make support recommendations for non-Intel GPGPU cards listed on its Tested Hardware and
Support List, based on the same support criteria. However, Intel cannot guarantee its server systems can
meet the thermal requirements of these non-Intel high power add-in cards. System integrators should verify
non-Intel GPGPU add-in card air flow and thermal requirements from vendor specifications before
integrating them into the system. It is the responsibility of the system integrator to conduct appropriate
system testing on server systems configured with a non-Intel GPGPU card to ensure reliable operation.
For non-Intel GPGPU cards listed on Intel’s tested hardware and OS list, Intel will provide best internal
support efforts to duplicate and understand reported issues. However, Intel cannot guarantee an issue will
be root caused nor that a fix can be made available to correct it.
5.1
Support Criteria
Due to air flow and thermal limitations, Intel® Xeon Phi™ coprocessor cards and non-Intel GPGPU cards can
only be supported in the following base system models: R2308WFxxxx, R2208WFxxxx, and R2208
8 Drive Accessory Kit (16x2.5” drive configuration).
See Appendix D at the end of this document for additional thermal configuration information.
Each Intel Xeon Phi coprocessor card and non-Intel GPGPU card must be installed into the top slot of a two-
slot PCIe* riser card. With a two-slot riser card installed, the embedded fan speed control operates system
fans at a higher speed. Three-slot riser cards (as shipped in the standard platform configuration) cannot be
used due to airflow and thermal limitations as embedded fan speed control does not drive system fans to
higher speeds needed to support the thermal requirements of these cards.
