Vertiv, a provider of critical digital infrastructure and continuity solutions, has introduced new power and cooling solutions for the edge of the network, including the Vertiv Liebert GXT5 Lithium-Ion double-conversion, online uninterruptible power supply system (UPS).
The company also introduced the Vertiv Liebert PSI5 Lithium-Ion Short Depth, a new, shallower configuration of their rackmount, line-interactive Liebert PSI5 UPS system, and two models of the Vertiv Liebert XDU Coolant Distribution Unit, Vertiv’s drop-in liquid cooling solution for high-density computing environments at core and edge sites.
“These products share two important characteristics. First, they support the increasingly critical and complex computing environments at the edge of the network,” said Ramesh Menon, vice president of single-phase UPS at Vertiv. “Second, and just as importantly, they support our customers’ sustainability efforts and our pledge to introduce sustainable solutions across the data centre ecosystem.”
Vertiv says they have leveraged the higher power density of lithium-ion to pack more battery runtime in the same amount of space as a typical valve-regulated lead-acid (VRLA) battery. The Liebert GXT5 Lithium-Ion, ranging in sizes from 1kVA to 3kVA, is designed to support scalable runtime, with a 1U lithium-ion external battery cabinet (EBC).
In addition, lithium-ion batteries typically last 8-10 years – roughly the lifespan of the UPS itself – compared to about 3-5 years for VRLA, potentially eliminating costly and inconvenient battery replacements. Lithium-ion batteries are also significantly lighter than VRLA batteries and perform better at higher temperatures, reducing the need for lower temperatures in the rack and by extension, lowering the costs of cooling.
The Vertiv Liebert PSI5 Lithium-Ion Short Depth UPS was designed with two-post racks and wall-mount racks in mind. These racks are common in small spaces at the edge, including retail locations, schools and universities, hospitals, and many telecommunications sites. These systems have the potential to enable a sustainable adoption of high-density computing in facilities operating with or without water cooling.
Suitable for chip cooling and rear door cooling applications, these CDUs keep the liquid circuit at an elevated temperature and operate at higher temperatures than traditional air-cooled equipment, ejecting heat through the liquid via a dry cooler and ultimately eliminating the need for mechanical cooling or chilled water circuits.
