The term “Data Center Tier 1 2 3 4” comes to mind when firms prepare to relocate critical Business applications and services to a data center tier level.
To assess the ability 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 difficulty 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.
What Are Tiers in a Data Center?
According to Data Center Tier 1 2 3 4 standards created by the Uptime Institute. Types of Tier Data centers are rated according to the redundancy systems they have in place. Then, each data center can be assigned to one of four tiers, ranging from 1 to 4.
Tier 1 data center requirements have the least redundant components. Whereas Tier 4 data centers have all the redundant components necessary for the best uptime.
Tier 1 Data Center
The lowest level of redundancy is seen in Tier one data centers. Which makes them vulnerable to outages during scheduled maintenance.
- Uptime:671% of the time
- Power: The facility will only have one non-redundant power connection.
- Cooling: Specific Cooling Devices
- Battery Life: 12 Hours
In order to filter power spikes, sags, and brief outages. Tier 1 facilities are also required to include a UPS. To meet the needs of the data center, there must be enough electrical capacity.
Due to the absence of redundant hardware to install and operate. A Tier 1 facility is likely to provide the most affordable server hosting. As a result, it is an excellent choice for data that doesn’t need to be completely available, such as cold storage for backups.
Tier 2 Data Center
Data centers in the Tier 2 requirements include redundant capacity components, and the data centers are served by a single distribution line.
- Uptime:741% of the time
- Redundant power: sources like an engine generator or fuel cells are available.
- Cooling: Dedicated Cooling, Redundant Chillers, and Heat Distribution Equipment
- Fuel: On-Site Storage for N Capacity for 12 Hours
- UPS: Redundant Modules
In the definition of a Tier 2 data center, individual components can be removed for maintenance without causing any downtime. However, servers may be dragged offline if the distribution path needs to be removed for any reason.
As every component needs to be shut down for regular maintenance, according to Data Center Tier 1 2 3 4 standards, the uptime Tier 2 data centers frequently experience a scheduled annual downtime. Without a backup distribution route, this data center frequently necessitates server outages.
Tier 3 Data Center
Data centers in the Tier 3 requirements have separate and redundant distribution paths in addition to redundant capacity components (cooling, power, etc.).
- Uptime:982% of the time
- Power: Backup energy sources like fuel cells or engine generators. several independent delivery channels to servers
- Cooling: Dedicated Cooling, Redundant Chillers, and Heat Distribution Equipment
- UPS: Redundant Modules
- Fuel: On-Site Storage for N Capacity for 12 Hours
To ensure that servers stay online in the event that one distribution path goes down. All servers in Tier 3 data centers are redundantly powered to the two distribution paths.
Tier 4 Data Center
The highest level of redundancy is included in Tier 4 data center requirements at all levels. In order to provide redundant capacity components and various diverse and independent channels that feed the servers.
Data Center Tier 1 2 3 4, these data centers have many independent, classified, and physically segregated systems.
- Uptime:995% uptime
- Power: Backup energy sources like fuel cells or engine generators. several independent delivery channels to servers
- Cooling: Dedicated Cooling, Redundant Chillers, and Heat Distribution Equipment
- UPS: Redundant Modules
- Fuel: On-Site Storage for N Capacity for 12 Hours
Hosting servers in a Data Center Tier 1 2 3 4 data center can be more expensive because it is very expensive to deploy and maintain all of the redundant parts. Additionally, you must pick a data center in the appropriate geographic area for your project.
