Services and functions to maintain
Available digital services within agreed operating conditions.
A data centre connects physical facility performance with digital service delivery. Available capacity and resilience can change with workload, maintenance, configuration and external supply conditions. Establish which services are supported, who operates each layer and how facility impairment translates into service consequences.
Relevant assets and dependencies
- Power supply, distribution, backup arrangements and cooling support IT operation.
- Connectivity, control systems, monitoring and current configuration information affect continuity and response.
- Workload placement, supplier support and maintenance activities can change the capacity available to absorb disruption.
Reduced cooling during an infrastructure change
A cooling component becomes unavailable while another component is undergoing maintenance. The consequence depends on current demand, the remaining capacity and the services hosted.
Bring facility and service teams together to assess options and authorise an appropriate response. Monitor the affected conditions, confirm the digital services remain within agreed bounds and review the combined maintenance exposure.
This example supports discussion of the framework. It describes no measured result or prescribed operating procedure.
Decisions TAR helps inform
- Assess current demand and available power or cooling capacity, including equipment unavailable for maintenance.
- Evaluate repair windows, operational adjustments and workload options with the responsible service teams.
- Agree approval, rollback and recovery arrangements, then verify both facility and digital service performance.
Evidence of the intended outcome
Select evidence that reflects the service, its agreed limits and the consequences of impairment.
- Digital service performance alongside facility capacity and operating conditions.
- Tests of backup and recovery arrangements, with assumptions and limitations recorded.
- Intervention records, approval history and confirmation that service and capacity were restored.
Record the baseline, assumptions and any remaining constraints. Review what the intervention achieved and use the findings to improve future decisions.

A hospital or university data centre retains this technical profile. Its service priorities should reflect the clinical, teaching or research activities it supports.
