VMware Cloud on AWS (VMC-A) Host Types Comparison

With the appearance of i4i nodes in VMC, I realized that I was missing a table in which I could compare all available nodes (i3, i3en, i4i) in details.

Enterprise Storage Synthetic Benchmarking Guide and Best Practices. Part 3. Practical Illustration based on Benchmarking VMware vSAN Case.

Well, let's go through the points outlined in Part 1 and Part 2 and look at an example of how testing might look end-to-end.

Enterprise Storage Synthetic Benchmarking Guide and Best Practices. Part 2. Success Criteria and Benchmarking Parameters.

As I mentioned in the first part of the guide, defining the goals and success criteria is a mandatory step for a successful POC. Of course, success criteria will vary, but they all have something in common — they should follow the S.M.A.R.T. rules:

Enterprise Storage Synthetic Benchmarking Guide and Best Practices. Part 1. General Theory, Methods, and Approaches.

And quite often I faced a situation where tests were not anyhow aligned with the business needs and even were technically incorrect which led to the impossibility to deliver any meaningful results.
