Good evening to all.
We are facing problems in identifying reliable hardware platform on which ESXi 7.0 can run.
Have you any suggestion regarding vendors (HP, Dell and so on) and platforms (for example server models)?
It depends on your needs. It's not just the server, but also the components like network adapters, controllers, ... which matter.
If you are going to configure the host yourself, make sure the components are supported (https://www.vmware.com/go/hcl).
The current trend is to have as much as possible a single provider in the Datacenter.
Specifically if you purchase hardware with a manufacturer, it would be advisable to also purchase VMware vSphere licenses and support with it.
The top manufacturers such as Lenovo, Dell, HPE and more also offer VMware vSphere licenses and support.
If you plan to opt for version 7.0 see the following link, consider having a couple of small conventional disks (300 or 600GB/15K/SAS) in RAID 1 to install VMware vSphere.
Refer VMware's Hardware Compatibility List for all of your additional supporting hardware, storage/ntw adaptors, etc.
Dell & HP provides custom ISOs for ESXis, you can consider them.
