ESXi on ARM/Raspberry Pi for vSAN Witness purposes or for?


Advertise here with BSA

I was just catching up on a couple of VMworld sessions. One session that stood out to me was most definitely once again the session by Chris Wolf and Daniel Beveridge. I am not going to write up a full coverage of it, as it is mostly very similar to the session they did in the […]

HA Futures: Admission Control – Part 2 of 4 – (Please comment, feedback needed!)


Advertise here with BSA

Admission Control is always a difficult topic when I talk to customers. It seems that many people still don’t fully grasp the concept, or simply misunderstand how it works. To be honest, I can’t blame them. It doesn’t always make sense when you think things through. Most recently for Admission Control we introduced a mechanism […]

VMworld Video: vSphere 6.7 Clustering Deep Dive

As all videos are posted for VMworld (and nicely listed by William), I figured I would share the session Frank Denneman and I presented. It ended up in the Top 10 Sessions on Monday, which is always a great honor. We had a lot of positive feedback and comments, thanks for that! Most importantly, it […]

UI Confusion: VM Dependency Restart Condition Timeout


Advertise here with BSA

Various people have asked me, and I wrote about this before in several articles but as part of a longer article which makes it difficult to find. When specifying the restart priority or restart dependency you can specify when the next batch of VMs should be powered on. Is that when the VMs are powered […]

My top VMworld session picks


Advertise here with BSA

Every year I post a list of my favorite VMworld sessions, my top picks. There are way too many sessions to see, but these are definitely the sessions I would like to attend personally. That could be because of the speaker, or the content, and preferably both. Yes I know, this list will have some […]

vSphere 6.5 and limits, do they still apply to SvMotion?


Advertise here with BSA

I had a question this week and I thought I wrote about this before but apparently, I did not. Hopefully by now most of you the I/O scheduler has changed over the past couple of years. Within ESXi, we moved to a new scheduler, which often is referred to as mClock. This new scheduler, and a […]

Module MonitorLoop power on failed error when powering on VM on vSphere

I was playing in the lab for our upcoming vSphere Clustering Deepdive book and I ran in to this error when powering on a VM. I had never seen it before myself, so I was kind of surprised when I figured out what it was referring to. The error message is the following: Module MonitorLoop […]

How to simplify vSAN Support!


Advertise here with BSA

Last week I presented at the Tech Support Summit in Cork with Cormac. Our session was about the evolution of vSAN, where are we today but more importantly which directly will we be going. One thing that struck me when I discussed vSAN Support Insight, the solution we announced not to long ago, is that […]
