The tested Intel Xeon E3-1285L v3 (Haswell) and the IBM Power 8 systems are single mainboard systems. The Intel C2750 (Avoton) and the ARM 64-bit Applied Micro X-Gene 1 are cartridges inside an HP Moonshot chassis. All tested systems are fitted with a BMC. In addition the HP Moonshot chassis also have an internal network switch, uplink module, internal network fabric, chassis fans, chassis manager module, etc. The Intel Avoton chassis is having a 1 GbE internal network fabric and switch with a 6x SFP+ 10 GbE uplink module (one port used) while the ARM 64-bit X-Gene 1 chassis is having a 10 GbE internal network fabric and switch with a 4x QSFP+ uplink module (one port used). The purpose of the off power measurements is to see how much power the chassis infrastructure is drawing. The power consumption of the Intel Xeon E3-1285L v3 (Haswell) chassis with the system off is very low, below the threshold of the Racktivity smart metered PDU used to perform the power measurements. The PDU reports 0, but the real power consumption is in the order of a few Watts. The tested Power 8 processor is inside a Tyan reference system GN70-BP010. Being a reference system, not all components and firmwares have been fully optimised. In the mean time Tyan has launched the TN71-BP012 platform which is not a reference system and should be much more optimised and ready for production use. I would be curious to see what are the improvements, but I don't have any at hand for now.
