سوال در مورد دیتا سنترهای tier3

[sherman2000]

tier ارتباطی با کپی رایت نداره و درواقع یکجور استاندارد دیتاسنتر حساب میشه و شامل موارد زیر:

• Tier 1 = Non-redundant capacity components (single uplink and servers).
• Tier 2 = Tier 1 + Redundant capacity components.
• Tier 3 = Tier 1 + Tier 2 + Dual-powered equipments and multiple uplinks.
• Tier 4 = Tier 1 + Tier 2 + Tier 3 + all components are fully fault-tolerant including uplinks, storage, chillers, HVAC systems, servers etc. Everything is dual-powered.

Data Center Availability According To Tiers

The levels also describes the availability of data from the hardware at a location as follows:

• Tier 1: Guaranteeing 99.671% availability.
• Tier 2: Guaranteeing 99.741% availability.
• Tier 3: Guaranteeing 99.982% availability.
• Tier 4: Guaranteeing 99.995% availability.
