You might be here because your organization is powered by your data center. Because of their importance, many businesses choose third-party-managed data centers to maintain essential systems, mitigate risk, and maximize uptime.
The name of the game is data center redundancy, but choosing a redundancy model can be difficult due to the enormous number of available solutions, none of which are comparable to one another.
Read on as we discover more about data center design, as well as redundancy and other factors related to this sector.
Understanding Data Center Redundancy
A data center's redundancy employs duplicated components, such as power supplies, servers, and cooling systems, in the event of a disruption in the supply of electrical power, a hardware fault, or a natural disaster. The great majority of redundant data center architectures are merely duplicates of each other's critical components. Consider how much it would cost to design a completely redundant architecture, with duplicates of everything to ensure a smooth transition in the case of a disaster.
Fortunately, it is not necessary to replicate every component of the data center in order to prevent disruptions. Having said that, you should be aware of the data center's redundancy levels and architectural options.
The Full Function Data Center Redundancy
When talking about redundancy in a data center, component protection should come first. Copying requires the usage of a power supply. Your data center will not be able to function correctly without UPS (uninterruptible power supply systems), even if it contains redundant gear. They often serve as backup power sources, cooling systems, and additional servers.
Despite OEMs' efforts to instill fear, uncertainty, and doubt (FUD) in the usage of third-party hardware maintenance, it can be used on both primary and backup systems. Seeking third-party assistance for redundant data center systems is a no-brainer. This is because redundant systems should lower any perceived risks.
Data Center Redundancy: The Levels
There is no single solution to the problem of redundant data centers. The data center's various layers of redundancy account for this. The levels are classified into:
● N
● N+1
● N+2
● 2N
● 3N/2
Data Center Redundancy Design: What is N?
Define "N" before moving on to data center redundancy design levels. The bare minimum of electrical or cooling capacity required for your data center to operate correctly under full IT load. If your data center requires five UPS units to function, N = five. Each data center's N rating represents the facility's power and performance needs.
Keep in mind that redundancy is not something that N considers. A straightforward approach. If N was five and a UPS unit failed, your data center would be unable to operate at full capacity. As a result, the operation necessitates N. Because this is impractical, firms build redundancy plans that exceed N.
Data Center Redundancy: Levels and Tiers
Tiers 1-4 (Tier 1, Tier 2, Tier 3, Tier 4) are used for data center certification purposes. They also have an effect on the multiple layers on redundancy.
More essential than a data center's N rating is whether or not it is operational. In comparison, Tier 1 data centers have an annual uptime of 99.671%, while Tier 4 data centers have an uptime of 99.995%. To provide uninterrupted service across all tiers, data centers must have several backup systems.
Conclusion
All this information may be intimidating and daunting to take in, but they are essential for running a successful business. Now that you know more about data center redundancy, and its levels and other facets, you can simply apply them to your line of work. This way, you will no longer have to worry about data breaches, data loss, and so on.
