HCI Mesh error: Failed to run the remote datastore mount pre-checks

I had two comments on my HCI Mesh compute only blogpost where both were reporting the same error when trying to mount a remote datastore. The error that popped up was the following: I tried to reproduce it in my lab, as both had upgraded from 7.0 to U2 I did the same, that didn’t result in the same error though. … [Read more...]

Does vSAN Enhanced Durability work when you have a limited number of hosts?

Last week I had a question about how vSAN Enhanced Durability works when you have a limited number of hosts. In this case, the customer had a 3+3+1 stretched cluster configuration, and they wondered what would happen when they would place a host into maintenance mode. Although I was pretty sure I knew what would … [Read more...]

vSAN File Services and Stretched Clusters!

As most of you probably know, vSAN File Services is not supported on a stretched cluster with vSAN 7.0 or 7.0U1. However, starting with vSAN 7.0 U2 we now fully support the use of vSAN File Services on a stretched cluster configuration! Why is that? In 7.0 U2, you now have the ability to specify during configuration of … [Read more...]

vSAN 7.0 U2 now integrates with vSphere DRS

One of the features our team requested a while back was integration between DRS and vSAN. The key use case we had was for stretched clusters. Especially in scenarios where a failure has occurred, it would be useful if DRS would understand what vSAN is doing. What do I mean by that? Today when customers create a … [Read more...]

vSAN 7.0 U2 Durability Components?

Last week I published a new demo on my youtube channel (at the bottom of this post) and it discussed an enhanced feature called Durability Components.

What if the disk controller driver included in my vendor’s ESXi image is not on the vSAN HCL?

Sometimes unfortunately there are situations where a vendor’s ESXi image includes a disk controller driver that is not on the vSAN HCL/VCG (VMware Compatibility Guide). Typically it is a new version of the driver which is supported for vSphere, but not yet for vSAN. In that situation, what should you do? So far … [Read more...]

VMs which are not stretched in a stretched cluster, which policy to use?

I’ve seen this question popping up regularly. Which policy setting (“site disaster tolerance” and “failures to tolerate”) should I use when I do not want to stretch my VMs? Well, that is actually pretty straight forward, in my opinion, you really only have two options you should ever use: … [Read more...]

vSphere HA configuration for HCI Mesh!

Advertise here with BSA I wrote a vSAN HCI Mesh Considerations blog post a few weeks ago. Based on that post I received some questions, and one of the questions was around vSphere HA configurations. Interestingly I also had some internal discussions around how vSAN HCI Mesh and HA were integrated. Based on the … [Read more...]
