Select Compute Resource

Assign the compute resource that will host your virtual machines. This determines the physical or virtual host cluster where the VMs will run.

Sections on This Screen

  1. Compute Resource Selection *

    Choose the appropriate compute resource for this build from your organization’s available infrastructure.

    Tree View Navigation:

    Displays a hierarchical view of available data centers and compute nodes.

    Example:

    ha-datacenter
└── esxi01.acmecorp.com

    Click on the desired compute node to select it. This selection determines the hypervisor or cluster that will host your VMs.

  2. Compatibility Check Panel

    After selecting a compute node, Sigma automatically runs compatibility checks to verify whether the selected OS, VM specifications, and resource requirements can be met.

    • Success: “Compatibility checks succeeded.”

    • Failure: Error messages will indicate issues like CPU generation mismatch, insufficient memory, or unsupported features.

Navigation Controls

  • Previous - Select Operating System

  • Next - Select Storage (enabled only after a compatible resource is selected)

Notes and Best Practices

  • Choose compute nodes based on location, workload capacity, and compliance requirements

  • Compatibility validation helps prevent common provisioning failures by detecting hardware mismatches or unsupported configurations early

  • The system may auto-filter hosts that do not meet the minimum requirements

Example Use Cases

Scenario

Recommended Action

You need VMs on a specific ESXi host

Select the corresponding node (e.g., esxi01.sigma-automate.com)

Building VMs in a DR site

Navigate to the appropriate secondary datacenter branch

Target node fails compatibility check

Choose an alternate compute resource or modify VM specs
