Ensuring reliability through certified data centre standards.

Ensuring high availability, reliability, and compliance through globally recognized data centre certifications and best-practice design standards.

Data Centre Tier Classifications

Understanding Availability, Redundancy & Design Standards

Tier 1 – Basic Non-Redundant Design

Minimal infrastructure with no redundancy

  • Single source of power and one cooling unit
  • No backup systems or failover capability
  • Not recommended due to risk of downtime
  • Very low availability

Tier 2 – Redundant Components, Limited Resilience

N+1 redundancy for power and cooling

  • Backup systems exist but rely on a single utility source
  • Not concurrently maintainable
  • Susceptible to panel failure or cable faults
  • Moderate availability, limited fault tolerance

Tier 3 – Concurrently Maintainable Infrastructure

Balanced design for uptime and maintainability

  • Full power and cooling redundancy
  • Independent cable paths and utility panels
  • Maintenance without downtime
  • Suitable for enterprises requiring consistent uptime
  • High availability with failover protection

Tier 4 – Fully Fault-Tolerant Architecture

Maximum resilience and 99.995% uptime guarantee

  • Dual power feeds from separate utility providers
  • N+N redundancy across all systems
  • Separate rooms for electrical, UPS, battery, etc.
  • Designed to handle unplanned failures without service disruption
  • Ideal for mission-critical operations
