SSH on OSX Mojave failing with broken pipe error


Advertise here with BSA

I recently upgraded my Macbook to OSX Mojave (10.14.1). Ever since I upgraded whenever I want to open an SSH session to any server on the internal (VMware) network I would receive the following error message: packet_write_wait: connection to x.y.z. port 22: broken pipe Very annoying as it made deploying labs in our dev cloud very […]

Cormac and I decided to update the vSAN Essentials book. We added a whole bunch of extra info and also decided to rebrand it. “Essentials” did not really cut it, it is much more than that. Considering I just finished the Clustering Deep Dive with Frank and Niels, we figured this could be a nice […]

Project Dimension – VMware’s Edge Computing effort


Advertise here with BSA

Internally some of my focus has been shifting, going forward I will spend more time on edge computing besides vSAN. Edge (and IoT for that matter) has had my interest for a while, and when VMware announced an edge project I was intrigued and interested instantly. At VMworld US the edge computing efforts were announced. The […]

Audio stops working on MAC / OSX


Advertise here with BSA

I have this issue where my sound / audio just stops working on my Mac / OSX. Very annoying, and as I find myself searching for the command every time I have this issue I figured I would simply drop it on my blog as a reminder, much easier to find, at least for me. […]

HA Futures: Per VM Admission Control – Part 4 of 4 – (Please comment!)


Advertise here with BSA

As admission control hasn’t evolved in the past years, we figured we would include another potential Admission Control change. Right now when you define admission control you do this cluster-wide. You can define you want to tolerate 1 failure for instance, but some VMs simply may be more important than other VMs. What do you […]

VMCP, or VM Component Protection, has been around for a while. Many of you are probably using this to mitigate storage issues. However, what if the VM network fails?
