Power management system based on multi-node micro servers and micro servers

Abstract

The invention provides a power management system based on multi-node micro servers. The power management system comprises a plurality of micro servers. Each micro server comprises a general purpose input / output (GPIO) interface. A power management bus is connected with the micro servers. An out-of-band (OOB) management chip is connected with the GPIO interfaces of the micro servers and is connected with the power management bus. The OOB management chip is used for sending power control commands to one or the plurality of micro servers, and controlling power supplies of the micro servers through the power management bus. The power management system carries out management on the power supplies of the multi-node micro servers through utilization of an in-band and out-of-band combination mode, ensures power running safety of the multi-node micro servers, improves power management efficiency of the multi-node micro servers, and is simple, convenient, and easy to use. The invention further provides the micro servers.

Description

technical field [0001] The invention relates to the field of server design and management, in particular to a power management system and a micro server based on a multi-node micro server. Background technique [0002] Currently, ACPI (Advanced Configuration and Power Management Interface) is used in traditional X86 platforms to manage server power. This method is only applicable to X86 platforms and cannot be used on other heterogeneous platforms. Use BMC (Baseboard Management Controller, baseboard management controller) chip to manage chassis power through ICMB (Iner-Chassis Management Bus, internal management bus) bus, each node needs a BMC chip for management, for example: the existing 2U4 Server, out-of-band requires 4 BMC chips to manage power, such as Figure 5 shown. [0003] The existing technology has the following shortcomings. The existing multi-node power management methods such as 2U4, 2U6 and 2U8 based on X86 use ACPI in-band for power management, which can o...

Problems solved by technology

[0002] Currently, the traditional X86 platform uses ACPI (Advanced Configuration and Power management Interface, Advanced Configuration and Power Management Interface) to manage server power. This method is only applicable to the X86 platform and cannot be used on other heterogeneous platforms. Out-of-band Use the BMC (Baseboard Management Controller, baseboard management controller) chip to manage the power supply of the chassis through the ICMB (Iner-Chassis Management Bus, internal management bus) bus. Each node needs a BMC chip for management, for example: the existing 2U4 The server requires 4 BMC chips to manage the power supply out of the band, such as Figure 5 shown

[0003] The existing technology has the following disadvantages. The existing X86-based multi-node power management methods such as 2U4, 2U6, and 2U8 use ACPI for power management in the band, which can only be used on the X86 platform and cannot be used on other heterogeneous platforms. For example, Heterogeneous platforms such as MIPS, ARM, or Tilera; out-of-band BMC chips are used for power management, and each node needs to use a BMC chip, which will undoubtedly cause serious waste of resources and increase costs and energy consumption; The power management is independent of each other, and it is impossible to deploy a safe power management strategy for multi-node deployment. If a large number of machines in a cabinet are powered on at the same time, the instantaneous current of the cabinet may be too large, causing a great potential safety hazard
