Slide notes list the CPU generations required for running VMware vSphere® ESXi™:
VMware vSphere® ESXi™ requires a 64-bit server (AMD Opteron, Intel Xeon, or Intel Nehalem).1. Correct:
Besides being out of date, this description is logically a nonsense: "Nehalem" is only one of the various Intel microarchitecture names and is a Xeon processor anyway, where "Xeon" is the Intel brand name for multi-socket-capable processors. Hence, mentioning "Intel Nehalem" as opposed to or an alternative to "Intel Xeon" is lexically a nonsense.1. Info:

When listing some of the configuration maximums for a host, slide notes state:
The server can have up to 160 logical CPUs (cores or hyperthreads) and can support up to 512 virtual CPUs per host.2. Correct:
The new configuration maximum for virtual CPUs per host is 2048. The number shown in the slide notes is related to vSphere 4.x.2. Info:

Slide notes show a list of hardware components a host must have:
The ESXi host must have:3. Correct:
- One or more Ethernet controllers
- A basic SCSI controller
- An internal RAID controller
- A SCSI disk or a local RAID logical unit number (LUN)
The above list cannot be considered a "must", yet - rather - a list of hardware components an ESXi host can have.
Just think of - in example - diskless hosts booting via PXE and deployed via VMware vSphere® Auto Deploy™.
