Tiers: A Classification System for Data Centers in Spain

The Tiers system is a classification framework developed by the Uptime Institute that defines the availability and reliability of Data Centers in Spain. Tiers allow companies to understand the level of redundancy and security they can expect when using a data center. Below, we explain each of the four levels, from the most basic to the most advanced:

Overview of Tiers in Data Centers

Tier Type Availability Downtime Per Year Features
Tier I 99.671% 28.8 hours No redundancy, vulnerable to interruptions.
Tier II 99.741% 22 hours N+1 redundancy in some systems.
Tier III 99.982% 1.6 hours N+1 redundancy, maintainable without downtime.
Tier IV 99.995% 0.4 hours Fully fault-tolerant (2N+1).

Tier I: Basic Data Center

  • Availability: 99.671%
  • Features:
    • Single path for power and cooling distribution.
    • No redundant components, making it susceptible to planned or unplanned interruptions.
    • Requires periodic shutdowns for maintenance.

Who is it for?

Small businesses or non-critical projects that can tolerate planned downtimes.

Tier II: Redundant Data Center

  • Availability: 99.741%
  • Features:
    • Basic redundancy in critical systems (N+1), reducing the risk of unplanned interruptions.
    • Can maintain service during minor infrastructure failures.

Who is it for?

Businesses needing higher availability but that can tolerate maintenance-related interruptions.

Tier III: Concurrently Maintainable Data Center

  • Availability: 99.982%
  • Features:
    • Maintenance can be performed without interrupting operations, thanks to multiple paths for power and cooling distribution.
    • Unforeseen events may still cause downtime, but interruptions are minimized.
    • Includes redundancy in key components (N+1).

Who is it for?

Ideal for medium and large companies that cannot afford downtimes during maintenance.

Tier IV: Fault-Tolerant Data Center

  • Availability: 99.995%
  • Features:
    • Multiple distribution paths and full redundancy (2N+1), enabling operations to continue during failures without interruptions.
    • Fault-tolerant critical systems ensure uninterrupted service, even during severe unplanned events.

Who is it for?

Critical sectors like healthcare or finance, where service continuity is essential, regardless of cost.

Comparison of Availability and Downtime by Tier

Tier Type Availability Downtime Per Year
Tier I 99.671% 28.8 hours
Tier II 99.741% 22 hours
Tier III 99.982% 1.6 hours
Tier IV 99.995% 0.4 hours

Common Mistakes When Choosing a Data Center Tier

  1. Choosing a Tier that’s too high without needing it: Many companies select a Tier IV thinking it’s the best, when a Tier III can offer sufficient availability at a lower cost.
  2. Underestimating downtime impact: Small businesses may underestimate the damage caused by unplanned outages when opting for a Tier I or Tier II.
  3. Overlooking future growth: It’s crucial to anticipate future growth when selecting a Data Center. A Tier III might be a better long-term investment as your business expands and requires higher availability.
