A data processing center (DPC) is a dedicated room (or building) that houses computing platforms, disk storage, and switching equipment.
The data center accumulates the organization’s data inside itself, processes it, and also guarantees its safety and provides backup.
Classification
Data centers are divided into several main types:
- A classic data center is an ordinary building with an increased level of protection. The equipment is placed according to the requirements that apply to the data center. This type appeared first and remains relevant today, despite other alternatives. Some customers independently build a data center for their tasks, while others prefer to rent.
- The cloud data center provides customers with a virtual space for tasks. This option is convenient because the customer receives a ready-made solution and pays only for the actual use of resources.
- The modular data center is assembled from different modules that are supplied to the customer. It is convenient to use in case of frequent travel.
- Container type. It is similar to the modular one, only it is delivered in a protected container. The main reason for use is the harsh operating conditions.
Customers can use different data center options depending on the current task. The cloud data center provides the greatest mobility, while the container model, which is deployed on the customer’s territory, has the maximum reliability.
Reservation
Any data center consists of various main nodes that ensure the efficiency and reliability of the data center. The most critical ones should be duplicated. When building a data center, there are two main options.
In the first case, an N+1 redundancy scheme is used, in which each critical component is duplicated. When one of them is disabled, the second one replaces it.
The second option is 2N, in which there are two independent components in the infrastructure. In case of failure of one of them, the second one takes over the load.
All other options involve mixing the first two in different proportions. For example, a 2N+1 solution means that the client has two identical components and one duplicate. Even if both fail, the third one will take over the load.
The last option that is used to ensure maximum reliability is 2(N+1). Any element, even a substitute, has its own double. Thus, the client receives a fault-tolerant infrastructure in which any element has at least one backup.
A data center is necessary for any enterprise. It ensures the storage and processing of information, as well as guarantees its security. Any data center is built on the principle of backup modules, which ensures reliability and guarantees the safety of data.
