Enhancing energy efficiency with Promise Technology
As energy costs rise and businesses look to use power in more sustainable ways, Promise is making strides to offer technology solutions that better manage resources and waste. Since disk drives comprise 70% of the total power usage of the subsystem, Promise provides its customers with a tiered power management option that is user configurable and adaptable to application environments.
Using Promise's stepwise process, users can configure different levels of power stages. Each step in the management level is designed to save power. From the Active state to Level 1 when drive heads are unloaded, there is a 10 – 20% power savings. Level 2, with lower spindle speeds has a savings of 30 – 40%. Level 3, when drives are spinning down, promotes 70 – 80% in power savings. Additionally, when needed, the entire process can be skipped pending user discretion.
Promise mitigates environmental impact by developing green products that reduce power consumption. We have adopted a high-efficiency power supply with 80PLUS Bronze/Silver/Gold certification for the Vess and VTrak product lines with MAID 2.0 support and On/Off power scheduling.
All Promise products are RoHS, WEEE, ISO1401 and REACH compliant. Additionally, we are reducing the use of hazardous materials like Pb, Cd, Br and halogens in all our products. PCB boards in Promise products are halogen free and are used in NPG150 in x30 products. Promise has also made a commitment to increase its usage of recycled materials whenever prudent.
