Data center migration: in view of the increase in MDC requirements, flexible facilities will be further developed and mature. The rise of the Internet of things, means more and more used in our daily life of things (watches, refrigerators, and other security systems we haven't even thought of things) will be connected to the Internet, continue to upload and download data, access database and storage data set, which will promote more rapid and low cost the deployment of data center. The use of flexible facilities will surely become an integral part of this expansion strategy, so as to provide necessary flexibility for business organizations and build strong internet based products and services.

Electrical modularized components
As with cooling, the power components of the modularized or container - containerized data center can be decomposed into several possible components from an electric power angle. These components include data equipment, mechanical cooling, main power distribution equipment and standby power supply.
A mechanical cooling system can also be located outside its own modular container or directly attached to a data container. This may require a single supply of power to these mechanical systems, or they can be supplied from the same power supply to the container system according to design requirements and layer levels.
The main field power equipment, such as the main switchgear, can be assigned and configured in a variety of ways in order to supply power for the modular data center form. One possible configuration is a simple outdoor rated shell, which may or may not be a walk-in type. These types of outdoor equipment are common in many types of projects, from the data center to the industrial park.
The standby power supply may include a standby generator, a UPS, a rotating or other system source. Due to its strict tolerance and environmental conditions, UPS is very suitable for container or modular units placed in integrated cooling. The outdoor generator shell is usually applied to many projects and can include a stepping and non stepping shell. Like switchboards, generators can be equipped with containerized chassis and integrated as part of a single source vendor's modular data center solution.
Usually, the central power system, including switchboards and UPS, can be specified in advance, and is located in pre production entity building or data center without walls. The data center container is not rare outside or in the entity structure. This hybrid method provides a more traditional central building for the maintenance and operation staff by using data containers, rather than using data center architecture.
Power supply configuration
Like the conventional data center, the electrical system used for modular data centers can be designed around various voltage levels, including 120 / 208, 480 / 277 and 400V. Another similarity is that modular containers can be configured or specified to conform to the overall system level. The Uptime Institute, which specifies the level of assessment, defines four types of hierarchies (level I, II, III and IV) for the electrical infrastructure topology. These layers define performance output for dedicated infrastructure, redundant components, concurrency maintainability, and fault tolerance.  In the actual data module or container, this tends to be attributed to the decision to provide redundant A / B power supply and internal allocation to the rack.
In the outside, the power connection of the data container can be taken in several forms. A hard connection with a traditional conduit, cable, and disconnecting device is connected to a packaged air processor connection. Or, modularized containers can use a more flexible plug - in connection.
The main power discrepancy of most data modules is the maximum power available when using a packed box data center method. In general, a single containerized data module will have a power limit of about 1MW for a data processing device. Based on the customer's computing requirements, the 1 MW limit will drive the number of individual containers required. This restriction does not apply to other types of modular, flexible data centers.
Grounding and lightning protection
The required grounding requirements for modular data containers are similar to any data center. Each container will have components with an inner earthing system to a rack and a container. However, engineers will need to design grounding systems for the site that supports a variety of modular data center containers and power systems. This usually leads to a grounding grid using an underground ring and a grounding rod, which interconnects all containers and systems into a low impedance system.
Besides the grounding system, the lightning protection system is usually designed, and the air terminal is placed on the top of the container, modularized structure, generator and other devices at the data center site.
