Nubis Solutions supports the European Union Code of Conduct for Data Centre Efficiency and is awarded Endorser status. March 2010
The European Union Joint Research Commission programme is a voluntary Code of Conduct to raise awareness of the opportunities for energy and cost efficiency that can be realised within the data centre. The Code of Conduct has been created in response to increasing energy consumption in data centres and the need to reduce the related environmental, economic and energy supply demands. The aim is to inform and stimulate data centre operators and owners to reduce energy consumption in a cost-effective manner without hampering the mission critical function of data centres.
The Code of Conduct aims to achieve this by improving understanding of energy demand within the data centre, raising awareness, and recommending energy efficient best practice and targets.
Endorsers are expected to utilise the Code of Conduct in order to develop products, solutions and programmes to enable data centre owners and operators to meet the expectations of the Code of Conduct.
As an Endorser Nubis Solutions actively disseminates the Code of Conduct recommendations and helps implement the Participant Guidelines and Best Practices to data centre owner / operators.
Nubis Solutions designs, manufactures and installs highly efficient and innovative Air Containment Solutions which enable an organisation to realise these energy and cost efficiencies and help them move towards Participant status.
Read our recent interview with The Hot Aisle. December 2009
"Nubis make demountable Aisle Containment systems - they don't care if it is Hot or Cold Aisle - the objective is to stop the air mixing.
Aisle containment has a number of well known issues mainly around safety and fire supression. Steve has a design that is optimised to get out of the way of fire detection and fire supression systems with two drop-down roof panel options ; Fusible Link and Water Soluble.
It is often the case that existing water-based fire suppression systems must be extended through the roof panels into the aisle to be effective, creating additional work, cost and disruption within a highly sensitive area of the business. Nubis recognises that in existing data centres enterprises want to preserve this investment.
In the event of a fire in the data centre Nubis's Fusible Link roof panels fall away at 58C to allow the fire suppression system to be effective (fire suppression systems typically kick in at 70C). If Water Soluble roof panels are deployed then water sprinklers simple dissolve them. Gas fire suppression is usually deployed through the floor tiles and in these cases the Nubis Gas Roof Panel provides an air tight seal to contain the gas and extinguish the fire. All the panels are quick and easy to remove by one person and allow full access to room facilities above the cabinets. Nubis further minimises disruption during ACS installation since it is non-invasive when attaching to sensitive equipment such as storage arrays, tape backup systems and PABX's.
Air Containment Solutions (ACS) are recognised as a simple yet highly effective means of reducing the power requirements to cool the data centre resulting in fewer equipment outages so improving business continuity. ACS reduces the data centre PUE rating, thereby minimising the carbon footprint resulting in savings of up to 20% from cooling power costs. This solution is neat because it is designed for existing data centers. The only constraint is that you have to have hot and cold aisles in place already"
Data Centre Cooling Power
Cooling of the Data Centre is widely recognised as the largest energy loss in the facility and as such represents a significant opportunity to improve efficiency. Improving air flow management is a key element to reducing power consumption from data centre cooling.
The objective of air flow management is to minimise bypass air, which returns to the CRAC units without performing cooling and the resultant recirculation and mixing of cool and hot air increasing equipment intake temperatures. To compensate, CRAC unit air supply temperatures are frequently reduced or air flow volumes increased, which has an energy penalty. Addressing these issues will deliver more uniform equipment inlet temperatures and allow set points to be increased (with the associated energy savings) without the risk of equipment overheating.

Uniform and Non-Uniform Cabinets. September 2009
We tailor make each part of the solution to match your needs; whether the cabinets are of a uniform size or height, different models or different manufacturers we can design a system to suit. We can also accommodate uneven aisles widths and lengths giving you a complete solution from start to finish.
Clear Path. September 2009
Clear path provide no floor level obstructions when you enter or exit the aisle through the sliding doors. We have a heavy-duty track system on the bottom of the doors to maintain rigidity but doesn't impede into the aisle walkways
Water Fire Suppression Roof Panels. June 2009
We have designed a system that releases our roof panels at a temperature 58oc (sprinklers are normally set to release at 70oc). This will allow the sprinklers to distribute water into the aisle without the added cost of altering your current systems.
Gas Fire Suppression Roof Panels. June 2009
To maintain positive pressure in the aisle we encase the edging of our roof panels with a rubber gasket to ensure an airtight seal. We also include a twist lock fixing to hold the panel in place in the event of the gas system discharge. All the panels are quick and easy to remove for a single person and allow full access to room facilities above the cabinets.
Room Lighting Levels. May 2009
All of our roofing panels maintain a high level of light (LUX). We design all of our roofing system to suit the current room layout so you don't have the added cost of introducing extra lighting to the aisles.
