Difference Between Tier 2 and Tier 3 Data Centers

The term “Difference Between Tier 2 and Tier 3 Data Centers” comes to mind when firms prepare to relocate critical Business applications and services to a data center. To assess the caliber and dependability of a data center’s capacity to host servers. The Tiering of Data Center standards was created.

The Uptime Institute created the concept of data center tiers. Which divided data centers into four categories: Tier 1, Tier 2, Tier 3, and Tier 4. The categorization is a sign of the sophistication of a data center’s overall availability and system redundancy in terms of design or architecture. The highest standard for a data center’s reliability is Tier 4 ranking.

Data Centers in Tier II

A Tier II facility must have an uninterruptible power supply (UPS), cooling systems, and auxiliary generators in addition to the criteria for a Tier I data center. With additional infrastructure and redundant (N+1) safeguards. Tier II data centers are less vulnerable to unplanned outages.

A Tier III data center standard typically contains one path for cooling and power as well as some redundant and backup parts. These facilities have somewhat greater predicted uptime than Tier I data centers at 99.741 percent (annual downtime of 22 hours).

Data Centers of Tier III

All of the standards for Tiers I and II must be met by a Tier III data center availability.

Data Centers in Tier II

Even totally fault-resistant technology is offered by a few Tier III data centers. They are marketed as Tier III+ data centers and boast 2N or N+1 for all infrastructure and systems.

For the vast majority of medium-sized to big firms and industries, a Tier III / Tier III+ data center is the most affordable solution. With a projected uptime of 99.982%, you may expect to have a downtime of no more than 1.6 hours per year.

A Tier III or Tier III+ data center is the wise choice for businesses that need a constant online presence because the risk is lowered to less than 2 hours annually.
