Becoming a VMware Storage Expert

How to become a VMware Storage Expert. Let me make it clear this is not a new certification VMware has introduced. This is a series I am starting to help people understand the storage part in the ESXi and implement it better.

I have engaged in several support calls where customers complain that the storage isn’t performing well, very high latency, production environment is down after the LUN’s failed over between the storage processors.

Becoming a VMware Storage Expert means you have to understand and master how ESXi works with Storage. I am starting a series in this blog to explain the components involved when a Datastore is presented (Block or NFS) and mounted to an ESXi, how VVOL works, also will touch-base on vSan.

We will go over all the topics about Storage & availability and explain in detail.

What happens to ESXi when it encounters events like APD-PDL

Few other outage scenarios causing the storage to be unavailable

Here is the Series.

  • ALUA- What is it and how it works
  • Storage Plugins- PSA, NMP
  • What are APD and PDL?
  • How to Handle APD and PDL?
