Use dynamic Power node Manager to save energy for enterprise

Does your IT system cost more and more? Are you at pains to reduce power and conserve energy? We will from the chip, components, systems, software and even data centers, and many other levels, from a number of points of view, sorted out a series of practical it energy-saving coup, I believe there is always a trick for you!

Power control is not only realized in the chip layer, but also can be realized in the node layer and the cabinet layer. Intel Dynamic Power Node Manager is one such technique. Node Manager is an Out-of-band (OOB) power management policy engine embedded in the Intel server chipset. It and BIOS and operating system power management (OS Management, OSPM) to dynamically adjust the power of the platform to achieve at the node (server) level to achieve maximum per watt performance.

It can be programmed, for a server, or a cabinet, or according to the application to define a good target power consumption value, and then monitor the system running under the target power consumption value, and performance will not have a big impact. Intel has done a test in Baidu, found that when a nominal 300W machine power to 260W, the impact on its performance is very small, so that the advantage is that we can use the software to control the maximum power of the machine in 260W, if 11545.html "> We have 10 servers, The equivalent of saving a server's power space, so that you can put more servers in a cabinet.

Node Manager has the following features:

Dynamic Power monitoring: measure the actual power consumption of a server platform and keep acceptable errors in +/+ 10%. Node Manager collects information from a power device configured with PSMI, provides real-time electricity consumption data (the average of a point or time period), and then reports up through the IPMI interface.

Platform power consumption Capping (Platform): Sets the platform's power consumption to a target power level, and maintains the maximum performance level on this power levels. Node manager accepts power policies from the external management console through the IPMI interface, and then maintains power at the target level by dynamically adjusting the CPU's p-states.

Power Threshold Alerting: The Node Manager monitors the actual power consumption of the platform according to the set target power consumption value. When the target power consumption value is unstable, Node Manager issues an alert message to the management console.
