Disclosed is a method and system which promote the development of Green Data Center management. The method implements intelligent algorithm within the server which allows Internet Protocol (IP) switching within the service processors in a lab. As a result, fewer IPs are needed and less energy is consumed in the process of fetching out-of-band data.

Method and System for enablement of Green Data Center Management with Innovative IP address management

A Remote Supervisor Adapter (RSA) is the Out-of-Band management interface card used with many server machines. Support for the Power Management task can be provided by service processors that can communicate Out-of-Band. Service processors provide support for the Power On, Restart Now, and Power Off Now subtasks.

In a setup for a Green Data Center having many power-consuming elements, such as hardware and servers, there is a need to monitor and control power and thermal data at the server level via systems management applications. Currently, each server requires a separate network port and Internet Protocol (IP) address to fetch data Out-of-Band from the service processor.

Labs or data centers may have limited availability to active/available IP addresses, preventing administrators from scaling-up the Green Data Setup for all the machines in the lab. In a general case, administrators would need three IP addresses:
1. Operating System (OS) system IP
2. Baseboard Management Controller (BMC) IP
3. Remote Supervisor Adaptor (RSA) IP

On the systems which have an RSA and a BMC, the Network Card is attached to the RSA and the IP is configured there. The BMC will not be accessible from outside the network. Management functionality is accessible from the RSA only.

In a scenario where ten systems in a lab are managed by a management server, due to the limited number of available of IPs within the lab network, administrators cannot assign IPs to all Integrated Management Module (IMM)/RSA cards.

There are two ways to communicate with the service processor (SP):
a. Out-of-Band: This requires a dedicated network connection to the service processor.

b. In-Band: This uses the communication path of the OS drivers to communicate with the service processor. A dedicated IP is not needed for SP.

IMM\RSA is used mostly in Out-of-Band for below use cases:
1. Management server and enterprise management software/system get power management data from the BMC when the server is completely ON. When the system is offline, the management server and enterprise management software/system need to communicate to the RSA for fetching the power consumption and configuration tasks.

2. The RSA needs to be active and accessible for other features (or for external purpose other than the management server and enterprise management software/system) and the same system needs to be active.

3. Provide web interface for remote administration (e.g., remote console for re-OSing the system or power on

Systems administrators need a method to provide improved IP address management so that a dedicated IP port to an RSA card can be optimally utilized. The solution would allow additional machines to be monitored via a management server and enterprise management software/system with optimum usage of physical n/w ports and IP addresses.
