Reduces the total power consumption for the server system as a whole by about 40%
Comparison evaluated with a server system consisting of 96 PRIMERGY CX 2560 M4 multi-node servers, comparing the power consumption of an air conditioning system and internal server fans against an immersion cooling version with the same configuration. Because the reduction effect depends on the installation environment, Fujitsu does not guarantee a power consumption reduction value in customer environments.
 Double the server density in the same installation space
Evaluated with a server system consisting of 80 PRIMERGY CX 2560 M4 multi-node servers, with 4 rack units required with air cooling that can be reduced to 2 immersion baths with the liquid immersion cooling method. Because the improvement depends on the installation environment, Fujitsu does not guarantee a degree of server density in customer environments.
 Power usage effectiveness (PUE)
A ratio showing the power usage effectiveness of ICT devices in data centers and server rooms, adding together the power consumption of ICT devices and the power consumption of associated equipment, such as cooling equipment, and then dividing by the power consumption of the ICT devices. A PUE of 1.0 indicates that all power is being used by ICT equipment, and none is being consumed by other equipment, such as cooling equipment. The PUE given here is the actual measured value from Fujitsu facilities, and because the value can vary depending on installation environment, Fujitsu does not guarantee a PUE value in customer environments.
 Coolant distribution units (CDUs)
Equipment that circulates the cooling fluid the server is immersed in with built-in pumps, transferring heat to coolant water through a heat exchanger.
 Offered as an option for the Fujitsu Server PRIMERGY series
Available for the existing PRIMERGY CX 2550 M4, PRIMERGY CX 2560 M4, PRIMERGY CX 2570 M4, PRIMERGY RX 2530 M4, as well as for future 2-socket multi-node servers and 1U rack servers offered by Fujitsu going forward.
