Current Projects

As a member of The Green Grid, you can take advantage of the association’s many opportunities to develop new metrics, build tools, and influence initiatives that enable the ICT industry to improve operations, increase efficiency, and deliver more sustainable products and services.

The Green Grid maintains more than 15 projects and numerous standing work groups on an annual basis. Highlights of projects currently underway include:

Infrastructure Utility Effectiveness (IUE)

This new metric is intended to help determine how much design infrastructure capacity an operational data center is able to use. It will measure data centers for effectiveness with a range between 100% (indicating design capacity can be fully used) and 0% (not unusable) with a real IUE between 0% and 100% showing some level of infrastructure usage deficiency or stranded capacity. Data center owners/operators will be able to gauge capacity usage effectiveness and where inefficiencies are and how to find ways to improve resource efficiency.

Power Metrics for IT Equipment

Building on its ICT Capacity and Utilization Metrics that measure data center capacity and utilization in the form of services in compute, memory, storage and networking, The Green Grid seeks to create new metrics that extend the analysis of the IT service areas to integrate a device's power and energy usage. Using the metrics will provide operators with information to assist in the measurement and trending of ITE energy efficiency and the ability to forecast and plan future power and cooling requirements.

Tropical Data Center Cooling Calculator

A data center’s physical location can have a significant impact on its PUE. The efficiency of identical mechanical systems can be drastically different depending on the climate in which the system operates. The local climate also affects the hours of free cooling available. Similarly, some mechanical systems are just not practical in some climates or locations. Location has a significant impact on utility rates and even energy availability. Thus, the objectives of the Tropical Data Center Cooling Calculator are to:

  • Provide an easy-to-use tool to estimate mechanical efficiency of different cooling methodologies, data center configurations, and server inlet temperatures
  • Use the Partial PUE (pPUE) metric, as defined in PUE: A Comprehensive Examination of the Metric, to quantify efficiencies
  • Promote a healthy debate on the effect of cooling technologies, data center configuration, and server environmental requirements in the efficiencies of data centers within tropical climates, characterized by uniform temperature and pressure, high humidity, and abundant rainfall

Liquid Cooling

With the release of the Liquid Cooling Technology Update, The Green Grid turns its attention to best practices and tools that enable data center owners/operators to realize efficiency gains at the IT and infrastructure levels from the implementation of liquid cooling technologies, including:

  • IT Design Enabling Multi-Refresh Liquid Cooling, which will establish recommendations for standardizing the interfaces of evolving liquid-cooled IT equipment to avoid or minimize facility-side changes
  • A Total Cost of Ownership (TCO) Calculator for Liquid Cooling Data Centers, which will reliably forecast the benefits of incorporating liquid cooling in a data center environment. This tool is planned to be flexible enough to integrate different liquid cooling technologies in variable IT environments, yet focused enough to provide a reasonable assessment of cost across the entire data center space

Open Standard for Data Center Availability Tool

The Open Standard for Data Center Availability (OSDA) promises to modernize data center availability classification and rating, similar to how PUE modernized data center power usage. This new approach, which will be applicable new designs and retrofits, will allow for data center designers and operators to increase resource efficiency and sustainability by integrating renewable energy sources into the overall availability considerations. Data centers will be enabled to access innovations and dynamically changing designs and power sources in the area of renewables. OSDA promises to be more inclusive, non-proprietary, flexible, and a means of fostering industry collaboration and innovation. The development of a companion tool will enable owners/operators to put the OSDA recommendations into practice and provide the ability to assess availability and reliability of their data centers.

Hunting Zombie Servers

By popular definition, a server is considered a “zombie” when it is unused, disused, or unproductively used, and it is no coincidence that zombie servers and neglected servers are often one and the same. These servers are among the most vulnerable to being compromised because they receive precious little IT department attention – it is both the cause and result of their zombie condition. Up to now, zombie server “hunts” – coordinated efforts to identify and de-commission under-used servers – are usually justified by perceived cost savings from reducing energy use, software licenses, data center space utilization, and operations budget. Those are legitimate benefits to culling your zombie burden, but the best reason may be to reduce the security vulnerability. The Green Grid is researching best practices for hunting, eliminating, and mitigating the risk these under-utilized severs pose.

Data Center Automation With a DCIM System

A data center infrastructure management (DCIM) system enables the data center operations team to monitor, remedy, report, and audit the evolution of an issue. It also automates systems and operations that support an agile data center. The work group will introduce the stages for automating your data center with a DCIM system and deliver a guide for individuals who need to proactively engage in maintaining uptime and ensure rapid deployment of data center services, desire an automated way to more accurately forecast capacity, and want to curb costs while assuring the highest levels of performance.

Redfish API Utilization

Redfish is a REST API specification and related schema published by the Distributed Management Task Force (DMTF) that defines a modern, secure, scalable management API for server, storage, network, and data center equipment. The Green Grid’s Redfish API Utilization project will provide prescriptive recommendations for architectural reference descriptions that incorporate manageability interfaces based on Redfish REST services, examples of equipment representation using Redfish-aligned data definitions and schema, and analysis of the value proposition for tools and evaluation algorithms using Redfish REST service APIs.
