vSphere 6.7 ICM – Topic 6.3 – Creating VMFS Volume.

Hello All! Hope you are learning  something new everyday.  Remember! Together we learn, Together we rise!

This blog helps you with the steps required to create a VMFS Volume in vSphere ESXi environment.

Points to Cover: –

  1. Creating a VMFS Volume.
  2. Key  Features of VMFS 6 over VMFS 5.
  3. Specifying the partition configuration for datastore.

In our lab we are connected to vCenter through webclient.

  • Select the ESXi host in the left pane2018-07-28 17_18_31-vSphere - cp-esxi-02.pathshala.com - Storage Devices.jpg


Once you right click on the host on the left pane, it will open a dialogue box as shown below-

In our next screen, we need to choose the VMFS version for the datastore. Please choose based on your requirements of environment.

VMFS 6  was introduced in vSphere 6.5 with following key features over VMFS 5-

  • VMFS 6 is not accessible to ESXi 6.0 and earlier.
  • VMFS 6 supports automatic space reclamation- It gives functionality to storage arrays to reclaim deleted or unmapped disk blocks a datastore.
  • VMFS 6 also supports space reclamation from Guest OS.
  • It supports 4K native drivers in 512e (Emulation) mode which means legacy applications and guest operating systems are supported.2018-07-28 17_19_29-vSphere - cp-esxi-02.pathshala.com - Storage Devices.jpg


Upon choosing the VMFS version, the next screen asks you choose the size of the datastore and the partition configuration. By default, it would be GPT unless specified.2018-07-28 17_19_35-vSphere - cp-esxi-02.pathshala.com - Storage Devices.jpg


At the end, it would ask you verify the details provided in the previous screens. Ensure to verify and return back if any changes are needed.
