2014 Score Card 56.7 56.4 51.4 C Enterprise Year on Year ITSx Performance 10 Data Centre Quick Wins ■ Install light sensors in Data Halls – don’t pay for lighting 24/7 when people are not there ■ Install rack blanking panels and side brushes – improves rack airflow and takes only a few minutes to install ■ Increase Data Hall temperature - refer to ASHRAE standards for guidance, check equipment and importantly increase the temperature in small increments ■ Use heat reflective paint on roofs ■ Increase chiller flow and return temperatures - usually set at 6/12 degrees (Celsius), these should be reviewed and can be raised to 10/15 degrees ■ Use adjustable floor vents to improve cooling and air flows ■ Repair and plug any leaks in Data Halls - up to 25–30% more energy is wasted through “leaked cooling”* ■ Install under-floor pressure control systems ■ Implement Cold / Hot aisle containment ■ Be more informed - review educative guidelines such as Green Grid, EU Code of Conduct, and the Australian NABERS rating for Data Centres *Data Centre talk, Daniel Prabhu, Mar 2012 What Is It? The Enterprise index looks at the associated sustainability performance of Data Centre operations in addition to the broader hosting environment of ICT infrastructure, Networks, Software Architecture. This index also looks at organisation’s adoption and readiness to outsourcing and cloud applications. Summary and Trends Enterprise and Data Centre sustainability performance has taken a definite backwards step over the past two years. The below par scores are disappointing considering the significant impact these operations have on the environment, and given that efficiency gains in enterprise management are almost always coupled with lucrative financial paybacks through reduced energy costs. However, the low scores across all sectors in this area provide an exciting platform for future win-win sustainability improvements from which businesses can now build. It is possible that the decline in Enterprise and Data Centre performance is due to the promotion of cloud and new hosting services that have prompted CIOs to refrain from further investment with existing data centres. With advancements in cloud platforms rapidly changing the data centre services landscape, data centres of tomorrow will look very different than those of 2012. For example, in 2012 cloud hosting such as Amazon Web Services did not exist. Today it has revolutionised software delivery processes. While data centre services is a rapidly evolving and changing landscape, there is no justification for corporate complacency nor a reason for CIOs to overlook proven ICT practices that clearly aid sustainability.
