DESCRIPTION
SMART POWER DISTRIBUTION UNIT FOR SERVER CABINETS
Technical Field
This invention is related to an electronic system configured to carry out the remote access control of, to measure the energy consumption of and to monitor the environmental conditions of servers placed in server cabinets at data processing centers.
The invention is a system configured to measure and control the energy consumption of servers from different companies at data processing centers and, by this means, to measure the energy consumptions of the corresponding companies. The invention is a system that monitors the environmental conditions of servers placed at data processing centers and sends warning notifications as needed to ensure their durability.
Prior Art Although there are many domestic server cabinet manufacturers today, they fall behind the foreign competitors. For many cabinet producers, the power distribution units required for the server cabinets are acquired from abroad. In foreign products, power measurements are in the form of power consumption for the whole of the cabinet, and thus, power consumption measurement per each socket has been carried out for the first time.
Turkish patent document number 2011/00290 of the known state of the art describes a measurement system developed for use in meters calculating energy consumption such as that of electricity, water and natural gas, wherein consumption values are automatically determined without the need to go near the meters and wherein such values are transmitted to the desired server. United States patent document number US2206259447 of the known state of the art describes a system related to determining and reporting energy consumption by means of a consumption meter.
Turkish patent document number 20 1/05148 of the known state of the art describes a point of metering and measurement system for electrical energy that is received from or supplied by a connection mechanism at a point at a fixed setting. Taiwanese patent document number TW201318543 of the known state of the art describes a server cabinet. The server cabinet consists of support plates, a cooling device and a body.
Aim of the Invention
The main objective of the invention is to provide a system that enables server cabinets used in data processing centers to be opened and closed, their energy consumption to be measured, shut down under negative conditions and for environmental conditions to be measured remotely over the internet/intranet.
Another objective of the invention is to provide a system that enables servers in data processing centers belonging to different companies or individuals to be monitored by their owners. Another objective of the invention is to provide a system that enables access over the internet and can send out notifications via e-mail and snmp in emergency situations, opposed to non-smart power distribution units placed in server cabinets. Another objective of the invention is to provide a system that is able to protect the servers from noise and interference from the mains. Another objective of the invention is to provide a system that allows energy supplied to the sockets servers to be accessed over a mobile phone or any internet browser (Internet Explorer, Firefox, Chrome, etc.) by means of a web server and each server to be controlled and monitored over a web interface.
Another objective of the invention is to provide a system enabling sensory information such as heat, humidity, flooding, gas leak to be acquired and providing a warning notification by e-mail, snmp when limits are exceeded.
Another objective of the invention is to provide a system that aims to prevent all servers from being affected by an outage or power fluctuations that may occur at any one phase in a so-called RST system wherein multiple servers in a cabinet work in equilibrium at different mains phases.
