The journey of ESXi 7.0.3 is legendary in IT circles—not always for the right reasons. When 7.0 Update 3 first launched, it was hailed as a major leap for vSphere. However, within weeks, it was pulled from the market. Admins who rushed to update found themselves facing critical driver conflicts and the dreaded "Purple Screen of Death" (PSOD).
