The data center is a global collaborative network of specific equipment, which is used to transfer, accelerate, display, calculate and store data information on the Internet infrastructure. Most electronic components in the data center are driven by low DC power.

The emergence of data centers has led people's understanding to move from a quantitative and structural world to an uncertain and unstructured world. Like transportation and network communication, data centers will gradually become a part of the infrastructure of modern society, and thus have a positive impact on many industries. However, the development of the data center should not only rely on experience, but also really combine practice to promote the data center to play a real value role and promote rapid social change.

Enterprise data centers:

They are facilities built and operated by enterprises to support their data processing and storage needs. It is generally placed in the enterprise park.

Managed Services Data Center:

Hosting service data center is a data center model deployed, managed and monitored by a third-party data center service provider. They provide features and functions similar to those of a standard data center, but through a hosted service platform.

Managed Data Center:

Generally, companies seeking hosting services rent space from hosting providers and provide management components, including servers, storage and firewalls, while the hosting data center provides the hosting infrastructure: buildings, cooling, bandwidth, security, etc.

Cloud data center:

Cloud data center is a new type of data center based on cloud computing architecture, which is fully virtualized.

Data center core components:

Routers, switches, firewalls, servers, storage systems, and application delivery controllers, as the basic infrastructure of the data center design, together constitute the core components of the data center: computing, storage, and networks. Three core components help ensure data security and availability.

Data center infrastructure standards:

The construction of the infrastructure of the data center is critical to the security of the data center, including generic cabling, partition decoration, uninterruptible power supply (UPS), computer room environment monitoring system, ventilation, cooling system, grounding system, lightning protection system, access control, monitoring, etc.

1: Basic capacity. The tier 1 data center provides a dedicated site infrastructure and physical protection of IT equipment. It does not include redundant equipment, tools and network services, and is the most basic technical layout.

2: Redundant capacity components. The tier 2 data center combines the features of the tier 1 data center with redundant IT equipment to improve availability and data protection. It includes multiple servers, storage, network equipment and telecommunications equipment.

3: It can be maintained at the same time. The Layer 3 data center has a high level of security to prevent almost all physical events. It uses redundant power equipment and networks to improve availability, accessibility and survivability, and can remove or replace each component without interrupting service to end users, thus greatly improving the uptime of the data center.

4: Fault tolerance. Tier 4 data center, which adds the concept of fault tolerance to the site infrastructure topology. All components can be designed as 2N full redundancy. Failure of any power or cooling infrastructure component will not result in downtime.
