# Data center infrastructure rack allocation

Data center infrastructure allocation reserves rack unit space in a data center based on the requirements specified in a change request and the placement policies that you have configured.

Data center infrastructure allocation evaluates racks in the target data center against the requirements in the change request and against the placement policies you have configured. The infrastructure then reserves rack unit space in the most suitable rack.

-   **[Create a custom placement policy](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/telecom-network-inventory/telecommunications-network-inventory/create-custom-placement-policies.md)**  
Create a Knowledge Base article that defines custom placement policies for your data center racks.

Reserve rack unit space in a data center by creating a data center infrastructure allocation change request and running the allocation.
-   **[Re-initiate rack allocation](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/telecom-network-inventory/telecommunications-network-inventory/reinitiate-rack-allocation.md)**  
Re-initiate the **Find Allocation** action on a change request to find new racks to reserve when your requirements change or when the initial allocation needs to be revised.
-   **[Rack allocation workflow](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/telecom-network-inventory/telecommunications-network-inventory/rack-allocation-workflow.md)**  
The rack allocation agentic workflow reserves rack unit space in a datacenter by evaluating placement policies, capacity metrics, and change request requirements to find suitable rack allocations.
