I wrote a blog post a while back about VMFork, which then afterwards got rebranded to Instant Clone. In the vSphere 6.7 release there has been a major change to the architecture of VMFork aka Instant Clone, so I figured I would do an update on the post. As an update doesn’t stand out from […]

vSAN Stretched Cluster: PFTT and SFTT what happens when a full site fails and multiple hosts fail?


Advertise here with BSA

This question was asked on the VMTN community forum and it is a very valid question. Our documentation explains this scenario, but only to a certain level and it seems to be causing some confusion as we speak. To be honest, it is fairly complex to understand. Internally we had a discussion with engineering about […]

I was talking to a partner and customer last week at a VMUG. They were running a two node (direct connect) vSAN configuration and had some issues during maintenance which were, to them, not easy to explain. What they did is they placed the host which was in the “preferred fault domain” in to maintenance […]

Cormac and I updated a bunch of Core Storage whitepapers recently, and one of them was the iSCSI Best Practices white paper. It appears that this little section about routing and […]

I had some customers asking where the storage performance proactive test and the multicast proactive test was in the latest release of vSAN.
