VSICM55 - Slide 11-09 - EVC Cluster Requirements



Room for improvement:

While describing the CPU vendors' supporting technologies for EVC, the second sentence in the slide notes states:

EVC automatically configures hosts whose CPUs feature Intel FlexMigration and AMD-V Extended Migration technologies to be compatible with vSphere vMotion with hosts that use older CPUs.
Correct:

The actual complete Intel's marketing name for the technology is Intel VT FlexMigration.

VSICM55 - Slide 11-07 - Other Cluster Settings: EVC for DRS



Wrong:

While describing how to enable EVC, the first sentence in the slide notes states:

In the VMware EVC section of the New Cluster dialog box, you can enable Enhanced vMotion Compatibility (EVC).
Correct:

In the vSphere Web Client, shown in the slide graphic, the mentioned section is actually called EVC only.

VSICM55 - Slide 07-46 - Cross-Host vMotion Migration Considerations



Wrong:

Both slide graphic and notes completely mess-up between Enhanced vMotion Compatibility (EVC) and Cross-Host vMotion. This mistake appears:

  • In the slide title.
  • In the bulleted list items within the slide graphic.
  • In each of the two paragraphs within the slide notes.
Correct:

Wherever you read either Enhanced vMotion Compatibility or EVC you should replace it with Cross-Host vMotion.

  • In the slide title.
  • In the bulleted list title within the slide graphic.
  • In each of the three paragraphs within the slide notes.
Correct:

Wherever you read either Enhanced vMotion Compatibility or EVC you should replace it with Cross-Host vMotion.

VSICM51 - Slide 13-19 - Remediation Enabled for DRS



Wrong:

Slide notes state:

EVC is not a prerequisite for VMware vSphere® Storage vMotion® migration. EVC guarantees that the CPUs of the hosts are compatible.
Correct:

Even if this is formally correct, here VMware vSphere® Storage vMotion® migration is completely out of context. The sentence should be read as:

EVC is not a prerequisite for VMware vSphere® vMotion® migration. EVC guarantees that the CPUs of the hosts are compatible.

Meaning that: even if EVC is not a prerequiste, vMotion will benefit from it as it makes ESXi hosts CPUs more compatible one each other.
