Data Centre

Data Centre – Overview

42-24’s Co-location Services give you full rack allocation at nominated 42-24 data centres in Derwent Park and Cambridge.

All 42-24 data centres include site security, access card entry, carrier-grade air conditioning, lockable rack cabinets, uninterruptible power supply (UPS), diesel back-up generators and environmental monitoring.

• Racks can accommodate a range of power requirements between 3kW and 21kW
• 650kVA diesel generators provide backup power to the entire site in the event of a mains failure
• Optimally efficient cooling design (hot aisle containment) available
• Site entry and access to each section of the facility controlled by proximity access cards and individual security codes issued only to inducted and authorised personnel
• Monitored 24/7 security alarm
• Internal and external CCTV monitoring on site, with full coverage of customer areas
• Swipe card rack access available
• All 42-24 data centres are carrier-neutral, and access to multiple service telecommunications providers is supported
• Geographically diverse fibre connections are available via the 42-24 telecommunications network

Data Centre – Technical

Power system

• Main electrical supply to the Derwent Park site comes via a dedicated 1500MVA transformer connected to the local grid in a ring-main configuration. This allows supply from two separate zone substations, with primary supply from a single substation – switchable to an alternate substation in the event of a prolonged substation outage, giving you a faster return to N + N resilience from the main switchboard to rack power distribution units.
• 2N electrical infrastructure downstream of Main Switchboard provides true concurrent maintainability of electrical infrastructure right through to customer racks.
• Dedicated generator mains board at the Derwent Park site provides the ability to isolate the main distribution board in the event of a mains distribution board fault.
• 650kVA diesel generators provide back up power to the entire site in the event of a mains failure.
• Racks can be configured to accommodate a range of power requirements between 3kW and 21kW (monthly rack rental includes 3kW per month).
• Power usage reporting for individual racks and managed PDUs available on request.

Cooling and environmental systems

• Systems utilised include:
  
  • Closed loop cooling (eliminating the need for constant water supply)
  • Hot aisle containment (recognised as the most efficient cooling design)
  • Emerson & Schneider in-row coolers, with chilled water distribution in a ring main configuration
  • Free air cooling via Dry Cooler, leveraging Tasmania’s cooler climate for a reduced carbon footprint and reduce Power Utilisation Efficiency (PUE)
  • Cooling system architecture: N+1
  • Environmental reporting available for individual racks on request

Security systems

• Documented Data Centre Policy and Access Protocols apply to all parties accessing the facility.
• Mandatory site induction required for all attendees.
• Adherence to Data Centre Policy and Access Protocols is compulsory to all authorised personnel.
• Entry to the site and access to each section of the facility is controlled by proximity access cards and individual security codes, issued only to inducted and authorised personnel.
• Monitored security alarm in operation24/7.
• CCTV monitoring is deployed internally and externally, with full coverage of customer areas.
• Swipe card rack access available (POA).

Fire detection and suppression systems

• Fire detection via multi-zone VESDA® system.
• Fire suppression ProInert™ IG-55 gas system or FM 200.
• Dedicated mechanical and plant area provides fire and suppression separation to data suites.

Third party carrier neutrality

• All 42-24 data centres are carrier-neutral and access to multiple service telecommunications providers is supported.
• Geographically diverse fibre connections are available via the 42-24 telecommunications network.
• Dedicated Carrier Room (MMR) provides clear demarcation between third party external carriers and customer racks

Service reporting

• Service Performance Reporting is available on request, with performance measures including but not limited to:
  • Environmental metrics
  • Power utilisation metrics
  • Access request logs
  • Authorised person register

Performance criteria

• The following performance criteria applies to all Co-location Services:

Service support period

• All Data Centre Services include the following Service Support Period (7 days, 24 hours per day).
  • Incident response is provided 24/7. All other requests will be actioned the following business day
  • All incident reports outside business hours MUST be made via telephone 1800 650 779 (opt 2)

Acceptance Tests

• 42-24 will complete Acceptance Testing for each new Co-location Service as part of the Service Provisioning process. Acceptance tests will:
  • Confirm delivery of power to PDUs
  • Test inter-connects and rack to rack cabling to relevant standards (note that the testing of inter-connect cabling is included in the Communications Services Acceptance Tests where these services are also provided by 42-24)
  • Include any additional test which may be agreed between 42-24 and the customer
  • Document the Test Results and will retain these for the period of the Agreement. Copies of the Acceptance Test documentation will be made available on request

Demarcation points

• Points for Co-location Services are:
  • Communications Interconnect – the customer allocated interface located within each rack
  • Carrier Room – optical distribution frame (applies to third party cross connects)
  • Power – customer side of power of the Power Distribution Units
