Clarification on Maximum Network Latency Guidelines in VCF 9.x Data Center Network Design

Products

• VMware Cloud Foundation

Issue/Introduction

This article explains about the maximum network latency specified in the VMware Cloud Foundation 9 Physical Data Center Network Design document, which is considered as a strict requirement and what are the potential impacts of slightly exceeding this threshold.

Environment

VCF 9.x

Resolution

The maximum latency guideline in VCF 9 is not a strictly enforced software limit; however, it is a critical design recommendation.

1. Installation: VCF 9.x allows installation even if latency exceeds the guideline.
2. Operational Impact: Exceeding recommended latency can degrade workload performance and jeopardize the stability of VCF operations.
3. Recommendation: To ensure stable performance, especially during high-demand periods, minimize network latency as outlined in the design documentation.
