In the past, a modularized design structure was difficult to implement in server systems due to the difference in mechanical dimensions and electronic specifications. However, since Intel defined new standard RPSU form factor CRPS, server suppliers have been able to offer modular system integration capability and design by upgrading power capacity based on different system application requirements.
At the early stage, due to limitations in internal design space, CRPS power units with higher than 1600W dimensions are hard to keep the same as those with lower watts. Luckily, with technological evolution in several product generations, the current mainstream specifications from 300W to 2200W follow a standard design specification.
Advantech has been designing products with CRPS power units into system applications, such as models with 300W to 800W for Telecom system applications and those with 800W to 2000W for storage servers and GPU server applications. Compared with previous redundant power supplies, these new power solutions enhance competitiveness in product cost and provide modular design and supply chain planning efficiency. Even now, Advantech is planning to phase in many compact CRPS units in 2019 with a maximum wattage of 2200W, among the same size CRPS for 2U 4-node servers.
