How to simulate Persistent Memory (PMem) in vSphere 6.7 for educational purposes? 

A really cool new¬†capability that was introduced in vSphere 6.7 is the support for the extremely fast memory technology known as¬†non-volatile memory (NVM), also known as persistent memory (PMem). Customers can now benefit from the high data transfer rate of volatile memory with the persistence and resiliency of traditional storage. As of this blog post, […]

Quick Tip - What hashing algorithm is supported for ESXi Kickstart password?

I had a question the other day asking whether the encrypted password which can be specified within an ESXi Kickstart file (denoted by the –isencrypted flag) can use a different hashing algorithm other than MD5? The answer is absolutely yes. In fact, MD5 as a default hashing algorithm has NOT been used for a number […]

Leveraging Instant Clone in vSphere 6.7 for extremely fast Nested ESXi provisioning

The idea of “Instant Cloning” a¬†Nested ESXi VM (running ESXi in a VM) is not a new concept.¬†In fact, I had shared a solution back in 2015 using the private VMFork APIs. However, what has changed is the ease of consumption, primarily due to the¬†re-architecture of Instant Clone in vSphere 6.7 (more details here and […]

Native MAC Learning in vSphere 6.7 removes the need for Promiscuous mode for Nested ESXi

Over the years, several solutions have been developed¬†here and here to help reduce the impact of promiscuous mode, which is a requirement for running Nested ESXi as a workload. Although these solutions worked extremely well, it however did require users to install additional software to enable this functionality. The most recent solution was a new […]
