Server maker Angstrom Microsystems has launched its MaxPowerSmart product which it says can "save large datacenters millions of dollars a year in electricity costs by cutting power waste to as little as 18%.
The firm says that using MaxPowerSmart with its racks tackles datacenter power loss which can often reach 50% of the power drawn from the grid and converted for use in the datacenter - meaning the other 50% is still drawn but wasted.
Angstrom says: "Phased 480VAC power enters the datacenter and passes through a UPS which can reduce power between 2% and 10%, datacenter power distribution units (PDUs) rectify this power to 208v with a 7%-25% loss of power, 208VAC current drives power supplies with a loss of 20-35% and A/C signals can experience an efficiency loss of 2-10% just travelling through the wire.
Street power - power entering the datacenter from "the street is typically 3-phase 480V in the United States. Each stage that it passes through, including the very copper wire transmitting it reduces its efficiency. By the time power reaches the mainboards for actual computing, it can lose nearly 50% of its efficiency.
Angstrom power solution savings derive from a 3-phase rectifier and DC power supply combination average at 84% efficiency. DC power solutions average at approximately 93% not including the rectification of A/C signal to DC. The Angstrom solution is a 480VAC 3-phase rectifier that converts VAC to 300VDC. Each blade, in turn, requires DC power and efficiently converts it to EPS standard used by most standard motherboards.
Lalit Jain, CEO of Angstrom Microsystems, said: "Our MaxPowerSmart ultra-efficient power solutions take a major leap forward in providing a broad spectrum of datacenters with a solution that suits their needs."
The company also makes liquid cooled blades, and green computing solutions for the datacenter.
