Data Center Tier Comparison

Financial services and high-tech companies demand ultra-low latency as well as a higher degree of data center redundancy in Data Center Tier Comparison. That is helpful to companies of all sizes.

One of the few Tier-4 data centers is in New York City. These facilities include the following features and were built with uptime and dependability in mind:

  1. Annual uptime of 99.995% (Tier 4 uptime)
  2. Fully redundant infrastructure with 2N+1 (the main difference between tier 3 and tier 4 data centers)
  3. 96-hour protection from power outages
  4. 3 minutes annually are lost.

Which Tiers are there?

The standard Data Center Tier Classification System was developed by Uptime Institute to reliably assess different Data Center Tier Comparison in terms of potential site infrastructure performance, or uptime.

The summary that follows should be read in conjunction with Data Center Tier Availability Standard. Topology and the related Accredited Tier Designer Technical Papers. The Tiers (I–IV) are progressive each Tier includes all of the lower Tiers’ requirements.

Tier I: Basic Capacity

An information technology infrastructure with dedicated site support is offered by Tier I data center requirements for use outside of offices.

A dedicated area for IT systems, an uninterruptible power supply (UPS) to filter power spikes, sags, and momentary outages, specialized cooling equipment that won’t shut off at the end of regular business hours, and an engine generator to safeguard IT operations from protracted power outages are all parts of Tier I infrastructure.

Tier II: Redundant Capacity Components Make Up

Requirements of Data Center Tier II facilities have redundant key cooling and power components to ensure safety against IT process interruptions brought on by faulty site infrastructure equipment and to offer limited maintenance possibilities.

Equipment for providing power and cooling, such as UPS modules, chillers or pumps, and engine generators, are among the redundant components.

Tier III: Concurrently Maintainable

No shutdowns are necessary for equipment replacement and maintenance in Tier III data center requirements. Each and every component is required to support.

The IT processing environment can be shut down and maintained without affecting the IT operation thanks to the addition of redundant delivery paths for power and cooling to the redundant critical components of Tier II.

Tier IV: Tolerance for Faults

Building on Tier III, and Tier IV site infrastructure adds the concept of Data center tier 4 fault tolerance to the topology of the site infrastructure.

When a piece of equipment fails or a distribution path is interrupted. Fault tolerance ensures that the consequences are prevented before they affect IT operations.

The Following Factors

Data Center Tier Comparison with Data Center tier Power redundancy and cooling are immediately addressed by the tier categorization in their general definitions. But there are a few more critical factors that may need to be taken into account:

  • Dependable electricity sources
  • Reliability and toughness of utility networks
  • Configuration of the utility distribution network and substations
  • Distribution and dependability on-site
  • Fire extinguishing equipment
  • Much more!

Each of the above-mentioned topics is worthy of its own article. The list above is provided to get your brain working. The point is that boosting uptime involves several different factors. In fact, even if all costs are avoided, danger cannot be completely eliminated, but it can be significantly diminished.

In Conclusion

The goal of this post, which is by no means thorough, is to persuade you to consider your levels of Data Center Tier Comparison infrastructure beyond the boundaries of your IT room, your building, and perhaps even your property line.

This is a useful resource for developing questions to pose to potential service providers if you’re a senior executive thinking about colocation or heavily utilizing cloud computing.
