Why We Are So Confident

Our Data Centre, Micron21 is the first and only Certified Tier 4 Data Centre in Australia. The most secure environment you can get.

Micron21 Tier 4 Data Centre

What is a Tier 4 Data Centre?

Data Centres are rated in terms of Tiers; one through to four. This represents the amount of redundancies in place for Power, Cooling, Fire, Data connections and more.

A Tier 4 data centre is considered the most robust and less prone to failures. Tier 4 is designed to host mission critical servers and computer systems, with fully redundant subsystems (cooling, power, network links, storage etc) and compartmentalised security zones controlled by biometric access control methods. The simplest iteration is a Tier 1 Data Centre used by small business.

Wikipedia has some great detailed information on Data Centres so we’ve taken the liberty of summarising some of the most important content below for easy reference.

Data Centre Quick Reference Table

Uptime Institute’s Tier Standards
Tier level Requirements
  • Single non-redundant distribution path serving the critical loads
  • Non-redundant critical capacity components
  • Meets all Tier I requirements, in addition to:
  • Redundant critical capacity components
  • Critical capacity components must be able to be isolated and removed from service while still providing N capacity to the critical loads.
  • Meets all Tier II requirements in addition to:
  • Multiple independent distinct distribution paths serving the IT equipment critical loads
  • All IT equipment must be dual-powered provided with two redundant, distinct UPS feeders. Single-corded IT devices must use a Point of Use Transfer Switch to allow the device to receive power from and select between the two UPS feeders.
  • Each and every critical capacity component, distribution path and component of any critical system must be able to be fully compatible with the topology of a site’s architecture isolated for planned events (replacement, maintenance, or upgrade) while still providing N capacity to the critical loads.
  • Onsite energy production systems (such as engine generator systems) must not have runtime limitations at the site conditions and design load.
  • Meets all Tier III requirements in addition to:
  • Multiple independent distinct and active distribution paths serving the critical loads
  • Compartmentalization of critical capacity components and distribution paths
  • Critical systems must be able to autonomously provide N capacity to the critical loads after any single fault or failure
  • Continuous Cooling is required for IT and UPS systems.
