NTP Compliancy: disable NTP sync with host completely (PowerCLI)

Last week I was identifying a root cause for a P1 outage my customer had suffered from. This customer has a business-critical application running 24/7 which is very important for all activities within the company. They had suffered an outage for at least three times last month, and therefore they requested my employer ITQ to perform a health check including a root cause analysis for the latest P1 incidents.


A match made in Heaven: Yamaha MT-10

For a couple of years, I drove a Kawasaki Z750 which was manufactured in 2008. Since last year I was looking for a new bike which just has some more ‘epics’ and more comfort as well. During the last year I have been searching the internet for the perfect model and every time the MT-xx series of Yamaha came across. So, there was no doubt anymore, my new bike will be a Yamaha MT-xx. But which one? MT-07, MT-09 or the MT-10. (more…)

Issue with replacing certificate for a new Load Balanced PSC setup (vSphere 6.5 & NSX 6.4)

Last week I ran into an issue while I was configuring a Load Balanced Platform Service Controller setup. My initial configuration was as follows: VCSA01 is pointed to the PSC01, and the VCSA02 is pointed to the PSC02 (within the same SSO domain). My goal was to load balance my existing Platform Service Controllers via a VIP on a NSX Load Balancer for the two vCenters and one NSX Manager (Connected to VCSA01).

Lab Expansion: Like in the old days

Currently i’m running my home lab environment on three physical Intel NUC devices. ESXi 6.5 is installed on each one of the NUCs and they are running a vSAN cluster (two M2 SSD inside each NUC, one for cache and the other for the capacity tier). Each NUC  comes with 32 GB memory and a Intel(R) Core(TM) i5-6260U CPU @ 1.80GHz installed as well. Due to the fact that the Intel NUCs are just not flexible enough for me to test certain scenarios I decided to expand my existing lab environment.


NSX-V: Create Logical Switches, Distributed Firewall Sections and Rules based on existing portgroup/vlans

In my previous blog post I wrote about how to automate the Enable MAC learning function on a VMware NSX Logical Switch via Powershell/PowerNSX. In this post I referred to a script which I used to export the configuration of the portgroup/vlans that where currently existing in the environment. I’m writing this blogpost, to share the script because someone might have a use case for it (more…)
