The IDC mains power supply is provided by a 22kV feeder, supplying a single 1500kVA 22kV/415V transformer.
Power to all hosting systems is conditioned and supported by 4 high capacity UPS.
Power is distributed through multiple Power Distribution Units (PDUs).
The environment is supported via a high capacity generator supply.
The generator has sufficient fuel capacity and is maintained onsite to provide approximately 83 hours of running capacity with priority fuel supply service.
In the event of an interruption to mains supply, Web24 power loads will be temporarily supported by UPS battery power while the on-site generator is engaged. If the interruption is brief, the power loads will remain supported by the UPS, otherwise the power loads will be automatically transferred to the generator supply.
The Melbourne IDC has 19 Process cooling units, of which four are separate air cooled units.
All air conditioning units are supported by the emergency power backup systems.
The Melbourne IDC has a Building Management System (BMS) that provides automated control and monitoring of all building services and environmental support systems.
Critical functions are alarmed and monitored 24x7 by staff for immediate intervention and control.
Critical environmental services are continuously monitored.
The Data Center has a water detection system in place. This system provides early warning of any water that may enter these operationally sensitive areas.
The water detection system is integrated with the BMS and monitoring via the NOC.
Fire Detection and Suppression
Fire detection systems installed in the Melbourne IDC include Passive Smoke Detectors (under floor, ceiling and above ceiling), Thermal Detectors (under floor, ceiling and above ceiling) and VESDA (Very Early Smoke Detection Apparatus). The fire detection systems are integrated with the BMS, and monitored by the NOC.
VESDA detects early signs of smoke particles within the data centre by actively sampling the air.
A wet-pipe recessed sprinkler system is installed throughout the facility for front-line fire suppression.
Physical and electronic security is managed by the Security/Administration office.
Entry into the Data Center for visitors and customers is via the Main Reception which has a staffed Security Station. Access is strictly by appointment.
Once within the Main Reception of the Melbourne IDC, a visitor or customer can be viewed from any angle. When ID has been confirmed visitors are issued with temporary passes, and are escorted at all times. A tight security clearance procedure is followed for IDC and Data Hall cage access by customers or known third party suppliers.
Access within the IDC is controlled via card readers. Different security levels are used to control an individual’s access to the various rooms of the IDC.
Customer security cages in the Data Hall are individually keyed. Issuing of keys is controlled by the Security/Administration office.
CCTV cameras are active and will record any security breaches.
The site has ASIO T4 certification.
In 2006 the site obtained the ISO 27001 certification.
Cabling Topology & Data Providers
Multiple telecommunications carriers are used to supply the external data communications links, enabling external connectivity redundancy. Currenlty these providers are Optus, Verizon and UECOMM
Category-6 cabling is used throughout the facility, and fibre-based connections can be used between the Data Hall and Node.
The Communication room is designed and configured for ease expansion and deployment of future-technologies. Device changes can be deployed within the Node and cut-over to the Data Hall will minimal interruption.
All cabling is laid in suspended trays that run under walkways between the caged areas. This design allows ready access for laying new cables to a new or existing cage, without having to enter a customer’s caged area.
Power and data are segregated as per Australian electrical and telecommunications installation standards.
