When deploying VMware vSphere on HPE ProLiant servers, using the generic VMware ESXi ISO is a common mistake that can lead to hardware compatibility issues, missing drivers, and poor performance. HPE rigorously tests its servers with VMware and provides a custom image pre-integrated with critical drivers (hpbootcfg, hpdsa, hpsa, i40enu, nmlx5, lpfc, qlnativefc), management agents (HPE AMS), and firmware utilities.
For those running legacy infrastructure but still requiring stability, ESXi 6.5 Update 3 (U3) remains a widely deployed version. This guide walks you through every legal and secure method to download the HPE custom image for ESXi 6.5 U3 in 2025.
Important Note: ESXi 6.5 reached End of General Support on November 15, 2022. However, HPE continues to host older images for existing support contracts. Only download if you maintain a valid VMware/HPE support agreement. download hpe custom image for esxi 6.5 u3

Recommendation: Download the ISO for a clean deployment.
Before you hit “Enter” on the installer, confirm: Important Note: ESXi 6
