A datacenter has exceeded the load on the central uninterruptible power supply (UPS). What is the best temporary solution for adding new servers?

Adding standalone UPSs for new servers not wired off the central UPS is a sound temporary solution when a datacenter has exceeded the load of the central unit. This approach helps maintain power reliability and protects new equipment from potential power issues caused by overloading the central UPS. By using standalone UPS units, the new servers can have their own dedicated power backups, mitigating the risks associated with energy fluctuations or outages, and ensuring that they function correctly without overwhelming the existing power infrastructure.

Plugging the new servers directly into the power that is not on the UPS may seem like a viable option, but it doesn't provide any backup during power outages, which can jeopardize server uptime and data integrity. Similarly, putting the central UPS on bypass increases the risk of failures during a power outage, as it disrupts the protective mechanisms that the UPS is designed to provide. Claiming that the actual load supported is higher than stated can lead to dangerous overloading, which may damage the UPS and the connected equipment. Thus, utilizing standalone UPSs ensures safety and continues to provide the necessary backup power for added servers.
