VSICM51 - Slide 14-07 - ESXi Hardware Prerequisites



1. Wrong:

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Besides being out of date, this description is logically a nonsense: "Nehalem" is only one of the various Intel microarchitecture names and is a Xeon processor anyway, where "Xeon" is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:

2. Wrong:

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:

For constantly up-to-date information about the Configuration Maximums, please always check the latest online version of the .PDF Guide.

3. Wrong:

Slide notes show a list of hardware components a host must have:

The ESXi host must have:
  • One or more Ethernet controllers
  • A basic SCSI controller
  • An internal RAID controller
  • A SCSI disk or a local RAID logical unit number (LUN)
3. Correct:

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™.
