Advertise here with BSA

I was talking to the HA team this week, specifically about the upcoming HA book. One thing they mentioned is that people still seem to struggle with the concept of admission control. This is the reason I wrote a whole chapter on it years ago, yet there still seems to be a lot of confusion. […]

Adding a fifth (virtual) ESXi host to vCenter Foundation


Advertise here with BSA

When running a 4 node stretched cluster environment it should be possible to use “cheaper” vCenter Server licenses, namely vCenter Foundation. One of the limitations of vCenter Foundation is that you can only manage 4 hosts with it. This is where some customers who wanted to manage a stretched cluster hit some issues. The issue […]

How to simplify vSAN Support!

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.

vSphere HA Restart Priority


Advertise here with BSA

I’ve seen more and more questions popping up about vSphere HA Restart Priority lately. I figured I would write something about it. I already did in this post about what’s new in vSphere 6.5 and I did so in the Stretched Cluster guide. It has always been possible to set a restart priority for VMs, […]

Changing advanced vSphere FT related settings, is that supported?


Advertise here with BSA

This week I received a question around changing the values for vSphere FT related advanced settings. This customer is working on an environment where uptime is key. Of course the application layer is one side, but they also want to have additional availability from an infrastructure perspective. Which means vSphere HA and vSphere FT are […]

New whitepaper available: vSphere Metro Storage Cluster Recommended Practices (6.5 update)


Advertise here with BSA

I had many requests for an updated version of this paper, so the past couple of weeks I have been working hard. The paper was outdated as it was last updated around the vSphere 6.0 timeframe, and it was only a minor update. I looked at every single section and added in new statements and […]
