Data Center Security is compartmentalized with biometric access controls. If your business prioritizes redundant capacity components, then you may want to look at this level of infrastructure. Companies who need a dedicated infrastructure solution beyond installing a server in their office for storing data could use a Tier 1 level data center. Tier 2 colocation data centers are more robust than Tier I centers. Mindestverfügbarkeiten garantiert heute jedes Service Level Agreement. Why data center tiers? Tier IV Data Centers have capability levels designed to host “mission-critical” servers and computer systems. Uptime Institute is the only organization permitted to Certify data centers against the Tier Classification System. The right server in the wrong location means lousy performance. For these customers, down time is very costly. The Uptime Institute categorizes data centers into four basic certification groups – Tier I, II, III, and IV. This gives the customers more reliability against disruptions. This is especially true as facility age. It guides enterprise customers to find the right level of redundancy for their needs, so they don’t invest more than necessary. Most experts agree that the standardized system has been well received. These standards classify Data Centers into 4 Tiers based on critical systems that determine uptime—1 being the lowest, 4 the highest. The way one expert put it: something as simple as running a power line to and from a system along the same wall can bump a Tier III down to a Tier II. Understanding their scope and value is essential for choosing a service provider. Our flagship facility, the connectivity hub of the southwest in North America, meets or beats the requirements of a Tier 3+ rated facility with all systems being greater than N+1 and concurrently maintainable.
