RETROFITTING HOT AISLE CONTAINMENT FOR GREATER EFFICIENCY
Telstra is Australia’s largest telecommunications which builds and operates telecommunications networks and data centres. Data centres have become increasingly more important to the business because of the rapid growth of digital content consumption and streaming services. According to Telstra Annual Report 2017, Telstra delivered over 5,000 petabytes of data on both fixed & mobile network each day, an increase of 40% compared to the year before.
EziBlank® hot aisle containment was a tremendous success with significantly improvement on cool-ing performance. The containment reduces the temperature fluctuation by 4.3°C or 73% and up to 35% saving on cooling energy costs. In addition, the real-time power monitoring also detected up 18kW of wasted energy due to in-correct configuration of the CRAC units. The success of this pilot study had instigated an energy efficiency initiative within Telstra Sustainability Business unit to incorporate new air flow management strategies inspired by EziBlank® solutions and also helped shaping operational strategies for data centre management group.
With the consumption of digital services continue to grow at an unprecedented rate, enabling efficiency
across all areas of data centre has become a business priority. IDC Solutions with more than 20 years data centre services experience was engaged by to conduct a case study of hot aisle containment using EziBlank® containment solution at Telstra Windsor T.E (Telecommunication Exchange). Windsor T.E. houses some of the high-performance data halls, with power density ranging from 2.5kW to 10kW per equipment rack, a H3 suite of 150kW capacity was selected as a the subject of this study. The immediate challenges faced by the project engineers were to seamlessly integrate a power monitoring system into the highly sensitive power & IT systems for measurement & verification and the feasibility of retrofitting airflow management components into a custom-build DC environment.
IDC Solutions installed power monitoring systems – a high accuracy energy/power data with zero interference to the 24/7 mission-critical infrastructure. On the airflow management side, EziBlank® containment solution was the only data centre ready solution in the market that could be retrofitted into any custom-build environments. IDC Solutions retrofitted EziBlank® blanking panels into vacant spaces within rack cabinets and EziBlank® Wall rack substitute panels were erected in air conditioned areas without rack cabinets.
Optimal hot aisle containment was achieved without out downtime or major works, EziBlank® installations were mostly plug-n-play where some small areas required minor modification. Customer & insurance underwriter were also satisfied with EziBlank® panels that are tested to UL-94 standards to be used without adverse risk within the mission critical facility.
