How to choose an IDC room to participate in Filecoin? Here is a complete introduction to IDC rooms

T1 data center can accept planned and unplanned interruptions of data services. It only needs to provide computer power distribution and cooling systems, and does not necessarily need to provide UPS or generator sets. Therefore, this is a single-loop system, which is prone to multiple single-point failures.

During annual inspections and maintenance, or in emergencies, the system will frequently shut down. Operational failures or equipment failures can also cause system interruptions.

The equipment of T2 data center has component redundancy to reduce planned and unplanned system outages. This type of data center requires the provision of raised floors, UPS and generator sets, and the equipment capacity design should meet N+1 backup requirements and single-route distribution.

When important power equipment or other components need maintenance, the system can be kept uninterrupted or interrupted for a short time by switching equipment.

T3-level data centers allow for any planned actions of supporting system equipment without causing any service interruption of equipment in the computer room. Planned actions include planned regular maintenance, upkeep, component replacement, equipment expansion or reduction, system or equipment testing, etc. Large data centers will install chilled water systems that require dual-circuit or loop water supply.

When other routers are performing maintenance or testing, the working router must have sufficient capacity and capability to support the normal operation of the system. Unplanned actions such as operating errors and equipment failures that cause data center interruptions are acceptable.

T4-level data centers require that the support system has sufficient capacity and capability to avoid the risk of downtime of important loads caused by any planned actions. At the same time, the fault tolerance function requires that the support system be able to avoid the risk of downtime of important loads caused by at least one unplanned failure or event, so this requires at least two real-time and effective distribution routes. N+N is a typical system architecture.

For the electrical system, two independent (N+1) UPS must be set up. However, according to the fire electrical code, the fire power system is allowed to be forcibly cut off in case of fire. Therefore, the T4 computer room requires all computer room equipment to have dual-circuit fault-tolerant power supply. At the same time, it should be noted that the T4 computer room support equipment must match the characteristics of the computer room IT equipment.
