ESXi 7.0 requires a boot disk of at least 8 GB for USB or SD devices, and 32 GB for other device types such as HDD, SSD, or NVMe.

For a list of supported network adapter models, see the VMware Compatibility Guide at. One or more Gigabit or faster Ethernet controllers.

To support 64-bit virtual machines, support for hardware virtualization (Intel VT-x or AMD RVI) must be enabled on 圆4 CPUs.

Provide at least 8 GB of RAM to run virtual machines in typical production environments.

ESXi 7.0 requires a minimum of 4 GB of physical RAM.

ESXi 7.0 requires the NX/XD bit to be enabled for the CPU in the BIOS.

Starting with ESXi 7.0 the partions layout is now totally changed. VMware ESXi 6.x partitions layout was the same from previous 5.x versions and there ware only some exceptions with bigger disks (with two different diagnostic partitions.

For a complete list of supported processors, see the VMware compatibility guide at. Reading Time: 5 minutes The VMware ESXi partitions layout on the system disk has remained almost the same for several years.

ESXi 7.0 supports a broad range of multi-core of 64-bit x86 processors.

ESXi 7.0 requires a host with at least two CPU cores.

For a list of supported platforms, see the VMware Compatibility Guide at. In fact if you check the ESXi Hardware Requirements you can see:

It is not intended as a comprehensive guide for planning and configuring your deployments.

Then I did force reboot and booted to ESXi fine without issue. This book, Performance Best Practices for VMware vSphere 6.7, provides performance tips that cover the most performance-critical areas of VMware vSphere 6.7. Will this couse possible issues in future upgrade? Or just in the update process there the scratch space could be too much limited? I think that this could be a problem and for this reason could be better consider 8GB the minimum recommended space for a ESXi 7.0 installation! I have not rebooted ESXi host for while and today I restarted a host and first time I get this message: 'Buffer too small'. As you can notice the new boot banks size are not 500MB instead of 1 GB and of course also the VMFSL partition is now smaller.
