Data center infra allocation change request reserves rack units using the rack allocation agentic workflow. The rack allocation
agentic workflow handles change requests and finds racks that can accommodate the capacity requirement based on specific physical and logical constraints.

## Data center infrastructure allocation overview {#data-center-rack-allocation__section_xkb_sgq_tjc}

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 you have configured.

When
a data center infrastructure allocation change request is submitted, the target data center, rack units, power, weight, temperature constraints, and any equipment specifications in Short description,
Description, and Work notes fields, are taken as input for rack allocation analysis.

Selecting the Find Allocation button initiates the rack
allocation agentic workflow. It handles change requests and finds racks that can accommodate the capacity requirement based on specific physical and logical constraints. The workflow processes change requests that require
rack unit allocation and creates Affected CI records. To learn more see
After data center infrastructure allocation completes, the change request is updated in the following areas:

* Work notes: The Placements and Decisions sections list the placement result, which racks were selected, which were excluded, and the reason for each decision.
* Review output panel: Displays the rack placement recommendation and a structured summary of the requirements as interpreted from your change request.
* Affected CIs tab: Shows the allocated slot and rack created automatically.

{#data-center-rack-allocation__ul_l4j_b3q_tjc}

In the rack view, reserved slots display the change request number. Select the number to view change request details, including the short description, requested by, scheduled dates, and current state, without leaving the rack
view.

When allocation fails, the Close Code field displays Unsuccessful as the status and the Close Notes field displays the reason for the failure.

## Re-initiating rack allocation {#data-center-rack-allocation__section_wr1_4kq_tjc}

When you re-initiate the Find Allocation action on a change request with the same or slightly modified short description that already contains Affected CIs, a dialog appears asking whether to continue
or finish without changes.

* Continue: The system treats slots marked as reserved from the previous run as occupied. This reduces available contiguous space and may affect which racks are eligible for the new run.
* Finish: The system exits without making changes.
