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 The paper was outdated as it was last updated around the vSphere 6.0 timeframe, and it was only a minor update.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 […]

In their particular case they simulated a site partition. During the site partition three things were expected to happen: VMs that were impacted by APD (or PDL) should be killed […]

In the past when deploying a stretched cluster (vMSC) it was recommended by most storage vendors and by VMware to set Disk.AutoremoveOnPDL to 0. This basically disabled the feature that automatically removes LUNs which are […]

I thought about it and said “no, that is not possible today”. Yes you can “disable HA restarts” […]
