Abstract:
This position paper discusses the role of energy-efficient cloud-server-on-chip (CSoC) solutions to reduce the total cost of ownership and the ecological impact of cloud computing data centers. A green cloud computing platform, based on a multi core architecture with upcoming 64-b ARM processors of the ARMv8 family, interconnected by a service-aware Network on Chip (NoC) ensuring cache coherency, could reduce costs (due to energy consumption and extra cooling systems) and increase system reliability (by avoiding thermal issues) of cloud data centers. Implementation figures on 28 nm and 20 nm silicon technology nodes from STMicroelectronics are provided.
