CONTROLLING POWER MANAGEMENT IN MICRO-SERVER CORES AND PERIPHERALS

摘要

Systems and methods of enabling power management in a micro server include providing multiple cores, a power management module coupled to the cores, and one or more peripherals coupled to the power management module. The power management module may be configured to cause the one or more peripherals to delay operations based on determining that the cores are in a first power consumption state, and place the cores in a second power consumption state for a predetermined time period. The second power consumption state may consume less power than the first power consumption state. The power management module may cause the one or more peripherals to resume their operations based on expiration of the predetermined time period and may place the cores in a third power consumption state based on the expiration of the time period.

主权项

1. A computer-implemented method comprising:
using side band communication, causing one or more peripherals of a server having multiple cores to delay operations based on determining that the cores are being placed into a first power consumption state; placing the cores into a second power consumption state for a time period, the second power consumption state consuming less power than the first power consumption state; using the side band communication, causing the one or more peripherals to resume operations based on an expiration of the time period; and placing the cores into a third power consumption state based on the expiration of the time period, the third power consumption state consuming more power than the first power consumption state and the second power consumption state.
