Data center power supply system

Power requirements depend on the desired level of availability and may include two or more utility lines, a UPS, a stand-alone generator, and multiple electrical circuits to systems and equipment. Determining energy requirements requires careful planning ahead.
Energy needs assessment involves determining the amount of energy required for all existing devices and devices that are planned to be installed in the future. The energy needs assessment should also take into account the needs of all ancillary equipment such as UPSs, generators, electronic converters, HVAC, lighting, etc. The assessment of the energy supply needs to be done taking into account the required redundancy and future growth.

Power supply systems in ffxiv data centres are implemented as systems with uninterrupted, guaranteed, and uninterrupted guaranteed power supply. The latter are used when it is necessary to ensure long-term autonomous operation: in the event of a disconnection of the main sources of power supply, the equipment is powered by emergency generators and UPS. The introduction of a UPS helps not only to avoid interruptions in the operation of the data center but also to reduce the number of equipment failures by improving the quality of power supply.
To increase the reliability of a double-conversion UPS, a static bypass (redundant inverter) and other design solutions are used – duplicated power supplies for the UPS electronics, separation and duplication of inverter, rectifier, and static bypass control systems
However, in the event of problems with the power supply, only the generators of electric current can provide the necessary readiness.


Examples of UPS systems:

APC Symmetra is modular and provides power redundancy in the event of a module failure. This UPS series is most often used in the construction of ffxiv data center split. Solutions built on top of APC Symmetra help ensure that the power supply remains operational in the event of a failure of one or more components of the UPS system. The following modules are redundant: Power, Control, Battery and Bypass Modules. The modular structure allows the UPS infrastructure to scale at minimal cost. APC Symmetra is part of the APC InfraStruXure data center solutions. There are several series of the Symmetra family. Medium-sized data centers are mainly built with the Symmetra PX series, which provides power from 10 KVA to 160 KVA. And for the largest data centers and data centers, APC Symmetra MW is used, providing power up to 1.6 MVA (1,

data center power supply systems


APC-MGE Galaxy is a high-performance and powerful UPS that can be used in large data centers and industry. MGE Galaxy supports stackable configurations, supports the same as Symmetra supports node redundancy, and among other things, supports redundancy of entire networks. With the help of MGE Galaxy, one data center can be connected to several power grids (several substations), and in case of a power failure in one network, it will automatically switch to a backup network. MGE Galaxy also supports the connection of controlled diesel generators, which can be started in the event of a power outage in all networks and when the UPS batteries are significantly discharged. MGE Galaxy provide a maximum power of 225 KVA.

uninterrupted guaranteed power supply of the ffxiv world status


For heavy loads, the battery capacity is consumed very quickly, providing a short backup time (or you need to take very large batteries). As a result, in order to provide power to such a load at least for a day, you will need to use a system of a whole hall of accumulators … And the issue of restoring their capacity after discharge is not very simple. The cost of such a solution will also be not small.
On the other hand, a diesel generator with a capacity of 100-500 kVA will cost much less money … Thus, already at the stage of organizing an uninterruptible power supply system in your business, you save significant money using diesel generators in conjunction with battery cabinets.
Diesel generators can also be used as standby (emergency) power supplies in those organizations where a constant uninterrupted power supply is required that does not depend on fluctuations in the central power grid. In this case, diesel generators operate during outages or power outages in the main network.
And if we take into account that, with reasonable use, diesel generators can last up to 10 or more years (depending on properly organized service and operating conditions), and batteries fail after a few years, the difference becomes quite astronomical. Therefore, in order to solve the problem of long-term guaranteed power supply, the choice in favor of diesel generators is obvious.
As a result, the use of one diesel generator for one or another section of the infrastructure requires the installation of a whole complex of supporting equipment, the laying of additional communications, special engineering work to isolate and eliminate vibration, and is a rather difficult task that requires a separate qualified approach.
