Data center s differ with parameters such us building physical security solutions, building and site characteristics, environmental control, technologies installed, location specifics etc. Data center Tier levels and EN 50600 classes are internationally recognized standards to help evaluate the quality and reliability of a data center’s ability to maintain functionality during various kinds of failures and define the overall security level of data center infrastructure that all together measure data center's potential uptime. Tier 1 is a non-redundant system that does not offer fault tolerance while Tier 4 level is fault-tolerant and any unplanned failures do not affect its operations. Some other differences between Tier levels you can see in the table below. DEAC data centers are designed according to Tier level III, level IV and EN 50600-3.
|Annual downtime, h
|Probability of discontinuance in 5 years, %
These are only some characteristics of Tier levels.
EN 50600-x (Information technology - Data center facilities and infrastructures) levels are European standard series that support independent and ambient definitions and requirements for data center design, planning, integration, installation, operation and maintenance of the facilities and infrastructures. This standard is developed by an independent and non-profit European standards organization and it is commercially neutral.
EN 50600 standard demonstrates the usage of the latest and advanced technologies to achieve maximum availability from the data center infrastructure. EN50600 classes include sections for building construction, power distribution, environmental control, telecoms cabling, security systems, management and operations.
