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.
Tier 2 Data Center
- 749% Uptime ( tier 2 Data center requirements)
- Partial (N+1) redundancy of components
- 22 hours of downtime per year
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).
There are still considerable hazards associated with employing a Tier II data center uptime, despite the fact that they might be an improvement over a Tier I facility. The plant still needs downtime for maintenance, and it cannot function without its lone utility power source.
Difference Between Tier 2 and Tier 3 Data Centers, Similar to Tier I, selecting a Tier II facility is largely determined by financial factors. Use of Tier II is recommended for non-mission essential systems and data, backups, and offsite storage.
A Tier II is still a dangerous investment if your firm substantially relies on shared systems and data.
Tier 3 Data Center
- 982 % Uptime ( tier 3 data center requirements)
- Fault-Tolerant (N+1) redundancy of components
- 6 hours of downtime per year
Data Centers of Tier III
All of the standards for Tiers I and II must be met by a Tier III data center availability. Because there are several channels for power, cooling, and systems in place at this level of facility, servers, networks, and systems can continue to function both during planned maintenance windows and unexpected outages.
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.
It makes sense to use a Tier III+ data center with full online operations if your company employs shared systems and cloud platforms. Without worrying about downtime, you can support your operations around the clock.
