Which environmental control is primarily responsible for maintaining optimal temperature and humidity levels in a data center?

Uninterruptible power supply (UPS)

A hospital's data center houses critical patient record servers. The facility is in a region prone to brief but frequent power fluctuations. The servers have dual power supplies connected to two separate UPS units, but there is no backup generator. During a recent storm, a 45-minute outage occurred after the UPS batteries were exhausted. Which additional control would MOST effectively address the risk of extended outages?

Implement a policy to shut down non-critical servers during a power outage.

Add additional battery packs to the existing UPS units to double the runtime.

Move the data center to a location with a more stable power grid.

Install a diesel-powered backup generator with an automatic transfer switch and a fuel supply contract.
