What is Lights-Out Data Center?
A lights-out data center is a server or computer room that is physically or geographically isolated at an organization's headquarters, which limits environmental variability and human access. Unnecessary energy used for lighting and maintaining a suitable climate around frequently used doors can be saved by turning off lights.
In addition to saving energy by keeping the data center dark and climate controlled, limiting human error is one of the main advantages of this approach to IT management. Having large numbers of people access to a data center increases the chances of losing a cable, tripping a power cord, tampering with storage, and many other minor incidents that can cause nightmares for IT administrators.
Some other benefits include:
- Lower insurance costs
- Less theft and other data breaches
- A more efficient use of IT resources
Ein Lights-Out-Rechenzentrum kann auch als Lights-Out-Serverfarm, Serverraum, Datenraum oder Servercenter bezeichnet werden.
A lights-out data center is basically sealed off from the rest of a building and the majority of the people who work in it. The data center can even be housed in a separate building that can be miles away or even in a different country.
One potential problem with using Lights-Out data centers is that resource management, air conditioning, troubleshooting, and all other tasks need to be handled remotely. That is, the remote access hardware and resource management software make this a relatively simple job.
Aside from external factors like an earthquake, geographically separated data centers can be just as reliable as a data center in the headquarters of an organization. In reality, the likelihood of an earthquake, explosion, or direct lightning strike is much less than the likelihood that someone spilled soda on the power supply or forgot to lock the server room door. For this reason, a Lights-Out data center is often much safer and more reliable than a conventional server room in the house.
