When tasked with analyzing the impact of deploying a new application in an environment utilizing an external storage array, the appropriate What-If Analysis in VMware vRealize Operations is Workload Planning: Traditional. This analysis allows administrators to model the addition of new workloads to traditional (non-hyperconverged) infrastructures, providing insights into resource utilization and capacity planning.
To perform this analysis:
Navigate to the What-If Analysis Section:
In the vRealize Operations interface, go to Plan > Capacity.
Click on the What-If Analysis tile.
Select Workload Planning: Traditional:
Click the ADD button.
Choose Add VMs under the Workload Planning: Traditional tile.
Configure the New Workload:
Specify the data center or custom data center where the new application will be deployed.
Define the workload profile by either:
Manually entering the number of vCPUs, memory, storage, and expected usage percentage.
Importing attributes from existing VMs to use as templates.
Set the Time Frame:
Enter the start and end dates for the period during which the workload will be active. The system can project scenarios up to one year from the current date.
Run the Analysis:
After configuring the workload, run the scenario to receive vRealize Operations' assessment.
The system will indicate whether the proposed workload fits within the targeted infrastructure and provide projections on resource utilization over time.
This process enables administrators to forecast the impact of new applications on existing resources, ensuring informed decisions regarding capacity and performance.
