We’ve reviewed and changed the lay-out for ESXi system storage partitions on its boot device. This is done to be more flexible, and to support other VMware, and 3rd party solutions. Prior to vSphere 7, the ESXi system storage lay-out had several limitations. The partition sizes were fixed and the partition numbers were static, limiting partition management. This effectively restricts the support for large modules, debugging functionality and possible third-party components.
That is why we changed the ESXi system storage partition layout. We have increased the boot bank sizes, and consolidated the system partitions and made them expandable. This blog post details these changes introduced with vSphere 7 and how that reflects on the boot media requirements to run vSphere 7.
