VSICM55 - Slide 06-11 - NFS



Room for improvement:

Slide graphic states:

Supports NFS version 3 over TCP/IP.
Correct:

As a fellow VMware and NetApp Certified Instructor has noted, the slide graphic should be better stating:

Supports NFS version 3 over TCP.

This as opposed to default NFS transport, which is UPD. Starting with NFS version 3 it is possible to choose between UDP and TCP.

RFC 1813: NFS Version 3 Protocol Specification - Paragraph 2.3 "Transport address".

VSICM55 - Slide 06-57 - Managing Overcommitted Datastores



Wrong:

Last phrase in the second paragraph of the slide notes states:

You can also use the storage reports to view disk space usage, for example, the Show all Datastores report in the Storage tab.
Correct:

The phrase actually has nothing to do with the vSphere Web Client, upon which the course is based, as it instead applies to Windows-based vSphere Client only.

In order to access the storage reports in the vSphere Web Client:

  1. Navigate to the Storage Reports link within the host Monitor tab.
  2. Select Datastores as the report type.

VSICM55 - Slide 06-54 - Creating a VMFS Datastore



Room for improvement:

Slide notes provide instructions about how to configure a new VMFS datastore:

  1. Select your host in the Host and Clusters view.
  2. Click the Manage tab and select the Storage link.
  3. Select Actions and New Datastore.
Correct:

Besides being formally correct, the list includes a few steps which are not compulsory: in order to be able to access the New Datastore task, it is not mandatory to navigate to the Host and Clusters view.
It is possible to leverage the New Datastore option within the Actions menu from wherever in the vSphere Web Client GUI, provided the target host has been selected in either the Host and Clusters view or the Inventory Lists tree.

VSICM55 - Slide 06-53 - Using a VMFS Datastore with ESXi



Wrong:

Last phrase in the first paragraph of the slide note states:

The maximum size of a VMFS datastore is 62TB.
Correct:

The actual maximum size of a VMFS-5 datastore is 64TB.

Source:

Configuration Maximums for VMware vSphere 5.5.



Room for improvement:

The second paragraph in slide notes states the following:

You can use an NFS datastore to store your virtual machines. But not all functions are supported. For example, you cannot store an RDM on an NFS datastore. A VMFS datastore is required for an RDM to store the RDM mapping file (*-rdm.vmdk).
Correct:

Despite the above is formally correct, it is a non-sense to detail NFS datastores limitations within a lesson dedicated to VMFS datastores. I would personally move the statement back to the NFS datastores lesson number 3, within the same course module, starting with slide number 29.

VSICM55 - Slide 06-33 - Configuring an NFS Datastore



Wrong:

The slide notes ordered list instructing you how to create an NFS datastore is either messed up between steps required in the vSphere Client and those in the vSphere Web Client or - in a case - completely wrong:

  1. Click the Storage link in your host’s Manage tab.
  2. Click the Add Storage link and select Network File System as the storage type.
  3. Enter the properties of your NFS datastore.
Correct:

As the "VMware vSphere: Install, Configure, Manage [V5.5]" course has transitioned to the vSphere Web Client GUI, the above list of tasks should be corrected as follows to describe the actual steps in the Web Client:

  1. Click the Datastore link in your host’s Related Objects tab.
  2. Click the Create a new datastore link and select Network File System as the storage type.
  3. Enter the properties of your NFS datastore.
