Unable to enable Private AI blueprint for projects using Cloud Consumption Interface in large scale environment

Products

• VCF Operations/Automation (formerly VMware Aria Suite)

Issue/Introduction

In VMware Aria Automation, you are unable to create a Kubernetes cluster for the Private AI service. This issue occurs specifically in environments containing over 500 projects.

Symptoms include:

• Cluster creation failure when using the Cloud Consumption Interface (CCI).
• Inability to utilize Private AI Foundation (PAIF) GPU guaranteed reservation features.
• Failure to scale Kubernetes orchestration within the modern tenancy (All Apps Org) model.

This typically impacts customers transitioning through an upgrade path from VCF Automation 8.x to 9.x, as PAIF features require modern tenancy and are unavailable in the 8.x series.

Environment

VMware Aria Automation 8.18.x

Cause

The root cause is a project scaling limitation within the CCI when operating under modern tenancy. Upon upgrading to version 9.x, both CCI and PAIF require the All Apps Org modern tenancy model, which currently cannot scale effectively for cluster creation when the project count exceeds 500. Soft-tenancy is not supported for these specific workloads.

Resolution

Permanent Resolution

Plan an upgrade to VMware Aria Automation 8.18.4 or higher once available. This release contains the formal fix to integrate scaling capabilities into the product core for high-project-count environments.

Workaround

If an immediate fix is required before the release of version 8.18.4, apply the provided hotpatch to your VMware Aria Automation environment.

Steps to apply:

1. Contact Broadcom Support to obtain the specific hotpatch for your version.
2. Apply the patch following the standard service update procedures.
