These are the Technicians and Engineers working various shifts, doing walkthroughs throughout the data center to monitor the equipment, performing preventative and corrective maintenance, diagnosing potential equipment issues while following their SOPs, and maintaining logs of their work. They are specifically responsible for the critical power, cooling equipment and building monitoring systems. These are the systems that allow the servers to stay online 24/7. In addition, Technicians and Engineers are on the front line and are the first responders if a problem arises.
There are also Critical Facility Operations Managers onsite. These managers schedule the technicians, oversee maintenance, escort vendors while they’re on-site, and put equipment procedures (SOPs / MOPS / EOPs) together for proper maintenance. They are also responsible for interfacing with either the client and/or owners of the facility and any potential customers that come to the site. The path to become a Critical Facility Operations Manager has been typically someone who has started working as a Technician or Engineer and demonstrated a strong proficiency in data center upkeep, working their way up from within the data center facility space.
