Data Centre Design
Uptime Institute certified Tier III Data Centre
The team has successfully built the only Uptime Institute certified Tier III Data Centre south of the Perth river with the following environmental friendly features:
Data Centre Construction
Single storey, non-descript building of 3,000m² on 9,600m² land
Total ICT white space of 2500m²
10 segregated data halls up to 248m² per hall
Office and common areas total 500m²
Raised flooring which exceed maximum equipment loading to 8.8kN concentrated load
Fire Prevention & Protection
Traditionally, Data Centres have relied on either water or inert gas as the chosen method of fire suppression. These are effective; however both have inherent problems with collateral damage.
The damage that water does is obvious but the inert gas systems have also had issues with corrosive residue and hard-drive damage due to the massive percussive blast when the gas is released. While newer gas systems appear to have overcome the corrosive effects, questions remain over long-term impact. It is also important to note that both these methods are after the fact: The fire has already started and begun its destruction.
As oppose to fire suppression commonly deployed, we have instead implemented the Oxygen Reduction Fire Prevention system. This is a fire prevention technology that is designed to prevent fire from occurring by reducing and maintaining oxygen at non-combustible levels. Each Data Halls will be filled with oxygen-reduced (hypoxic) air, coupled with VESDA, provide the highest level of protection to all valuable assets, including ICT equipment.
VESDA (very early warning smoke detection and alarm) system, smoke detectors installed throughout facility. The VESDA is designed to alarm the site personnel in the event of a smoke detection within the facility so that immediate action is undertaken. It is also connected to the fire department as an added measure.
Fire prevention using hypoxic air. The hypoxic air is breathable air and safe for the people and the environment. No chemicals or gases are involved.
Data halls are also constructed to FM 4880 (Class 1 fire rating) fire performance requirement
Uninterruptable Power Supply based on Flywheel Technology
The Flywheel UPS's use of 100% kinetic energy is a key feature to allow unlimited and fast charge/discharge cycles to clean and correct power quality and power factor. In contrast, chemical battery gets consumed every time current flow thru them (in a non-deterministic way). There is no chemical battery storage on site.
The UPS have static switches, chokes filters and other systems to address all 9 power qualities issues described by IEEE. The flywheel is always connected (no switching between mains and energy storage) and is more efficient because in normal operation very little power go thru the two inverter/rectifier modules.
Another advantage is allowing parallel feeds, that is allowing multiple UPS to be sync and feed on a common bus. With load increment or maintenance purpose, the power module(s) can be added online/offline and sync without interruption.
