The current indexes for data center performance, such as DCiE, EUE and PUE are not sufficient to drive data center efficiency. These indexes focus only on the power or energy consumption of the facilities. Each metric in itself says nothing about how efficient a data center really is. In order to drive and improve efficiency, a common framework that will describe any data center, anywhere, doing anything is required. The next step is to apply industry established metrics for each block that is running in the data center. The combination of a framework and the metrics can form the basis of real data center performance monitoring.
And here come two things together.
Data Center Pulse (DCP), a non-profit, data center industry community founded on the principles of sharing best practices among its membership is working on Standardized Data Center Stack Framework Proposal The goals of the Stack are: Treat the data center as a common system which can be easily described and measured Provide a common framework to describe, communicate, and innovate data center thinking between owner/operators peers and the industry. So the aim is simple – provide one common framework that will describe any data center, anywhere, doing anything. The next step is to apply industry established metrics for each block that is running in the data center.
Another initiative is the open source Open Data Center Measure of Efficiency (OpenDCME). In this model 16 KPIs that span the data center are used to measure data center efficiency. As stated “This first version of the OpenDCME model is based on, amongst others, the EU Code of Conduct for Data Centres best practices in combination with the feedback of applying the model to a large number of data centers.” Mansystems , a European IT specialist in service management, consultancy & support, created and released OpenDCME. The proposed measures belongs to the community and is open for contribution by using the Creative Commons license agreement. The model consists of four domains:
- the IT assets that are located in the data center,
- the IT assets efficiency
- the Availability, Performance and Capacity of the IT assets,
- the efficiency of data center IT processes.
The radar plot shown below is the presentation of the 4 domains and the 16 KPIs (4 per topic). The OpenDCME model, in its current version, does not tell you HOW to measure the 16 KPIs.
Comparing the Stack Framework and the OpenDCME model initiatives you can see that both are complimentary to each other. Bringing these to initiatives together can accelerate the development of performance monitoring and management of data centers.
Lets see what happens …
