ESXi itself needs 1 G or less. I am speaking about the memory ESXi will provision for VMs. The expectation of the documentation is that you need at least 12 G to actually perform anything useful. The docs mean physical memory in your ESXi host that will be used by ESXi itself and VMs.
So my recommendation from the start has been to configure a system with 32 G. Assign 16 G to TrueNAS and use the rest for your other VMs. Since ESXi can overprovision and share memory, the limits are not that exact. You can run 4 VMs of 4 G each and ESXi will "find" memory for its own use.
