NO. Requirements in this Relationship with related specifications from other SDOs
Recommendation
– [b-OCP MB] provides storage hibernation as 'The BIOS should be tuned to
minimize system power consumption and maximize performance. This
includes: Disable any unused devices, such as unused PCI, PCIe ports, USB
ports, SATA/SAS ports, clock generator and buffer ports. Tuning
CPU/Chipset settings to reach minimized power consumption and best
performance in a data centre environment' in clause 6.3.1.
13 Hardware-assisted I/O – [b-OCP OBIOS] describes how Intel Virtualization Technology (Intel VT) must
virtualization be supported via platform BIOS policy variable, in clause 4.8.

14 I/O devices direct – [b-OCP 25GDual] describes how QL41202 shall support single root I/O
accessing virtualization (SR-IOV), in clause 12.
15 Workload offload – [b-OCP 25GDual] describes how QL41202 shall support offload traffic types
RDMA over Converged Ethernet (RoCE) on each of the ports and also
support Internet wide area RDMA protocol (iWARP), in clause 12.
16 Hardware acceleration – [b-OCP OBIOS] describes key features for WCS Intel Xeon Scalable Platform,
support 2 GP-GPU+1 PCIe card in 2U, in clause 2.2.
– [b-OCP BS] describes QCT Grantley platform will be 16 DIMMs and support 8
GPGPU cards and Max. 8x 2.5"HDDs' in clause 1.
17 Power supply – [b-OCP OCSSSD] describes how OCS v2.0 servers shall support drives with
replacement volatile write caches by leveraging the server backup power supply in clause
11.3 Power-Loss Protection.
– [b-OCP OCTAM] Indicates that when PSU ALERT# signal occurs, the Olympus
PSU has transitioned its power source from AC to battery backup, in
clause 7.4.
18 Supporting power – [b-ETSI EVE007] provide power redundancy as 'Power supply redundancy
redundancy may be achieved by installing more than one power supply unit' in
clause 5.3.3.2.
– [b-OCP 1S] require platform designers to provide adequate power and
cooling to properly handle the SoC's power and thermal requirements, in
clause 3 overview.
– [b-OCP 1S] require Twin Lakes 1S Server to provide a standby 3.3V_AUX
power rail on the card to power the Bridge IC at all power states, in
clause 8.1.2.
– [b-OCP HSAS] describe that the Hyve Solutions Ambient Series-E servers
support single or redundant power supply, in clause 11.
19 Minimum energy – [b-ETSI EVE007] provides minimum energy consumption as 'different forms
consumption of processors would be utilized for different types of services to improve
power efficiency' in clause 5.2.
– [b-OCP 1S] describes that the Twin Lakes 1S server recommend a power-
capping implementation to reduce the server's power consumption (cut off
power in certain time) in clause 8.4.
– [b-OCP OAPM] describe that the motherboard supports Emergency Power
Reduction mechanism (PWRBRK#) for the x16 PCIe slots in clause 7.5.
– [b-OCP OCTAM] describes how the motherboard supports Emergency
Power Reduction mechanism (PWRBRK#) for the x16 and x32 PCIe slots in
clause 7.5.
– [b-OCP OMB] describes how the motherboard supports Emergency Power
Reduction mechanism (PWRBRK#) for the x16 PCIe slots in clause 6.5, the
main purpose is to provide a power reduction mechanism for GPGPU cards
as part of the throttle and power capping strategy.
