Dormancy/wakening method for server and server with dormancy/wakening function

Abstract

The embodiment of the invention provides a dormancy method for a server. The server comprises a system management board and at least one single board, wherein each single board comprises an intelligent management controller. The dormancy method for the server comprises that: the system management board receives a dormancy signal transmitted by a remote host computer; and the system management board transmits the dormancy signal to the intelligent management controller of the corresponding single board so as to cause the intelligent management controller of the single board to control the single board to enter a dormant state according to the dormancy signal. The embodiment of the invention also provides a wakening method for the server, and the server with a dormancy / wakening function. Theintelligent management board of the single board controls the single board to enter the dormant / wakened state according to the received dormancy / wakening signal, so the embodiment of the invention realizes the dormancy / wakening function of the server, and can make the single board of the server consume less electric energy when the load is relatively lower, effectively save the energy consumption, and when the traffic is boosted, quickly waken the single board of the server to share the load.

Description

technical field [0001] The present invention relates to the technical field of servers, in particular to a server dormancy / wake-up method and a server with a dormancy / wake-up function. Background technique [0002] In December 1996, five companies including HP, Intel, Microsoft, Phoenix, and Toshiba jointly drafted the ACPI specification to replace the previous APM power management specification. APM implements power management functions at the BIOS level, while ACPI implements power management at the operating system level. In the ACPI specification, the system operation status is subdivided into six categories: S0 / S1 / S2 / S3 / S4 / S5, and the system power consumption decreases in turn. [0003] The commonly referred to as the S3 state is the Suspend to RAM (STR) state. As the name implies, STR is to store all the working status data of the system before entering STR into the memory. In the STR state, the power supply continues to supply power to the most necessary devices su...

AI Technical Summary

Problems solved by technology

In the special field of servers, it is generally believed that servers must provide services 24 hours a day, so they cannot enter a dormant state, so most servers do not support the S3 function

However, with the increase of operating costs, the power consumption of servers has increasingly become a relatively large cost in the operating cost structure of Internet Service Providers (Internet Service Providers, ISPs) and Internet Data Centers (Internet Data Centers, IDCs). overhead, which is why today's new servers and server processors are emphasizing power saving
