vSAN Storage Rules policy capability allows to set dedupe per VM?

There was a question posted on the VMware Community Forums, and as this is something I have been asked regularly, I figured I would do a quick blog post about it. Although I have covered this before, it doesn’t hurt to repeat, as it appears to be somewhat confusing for people. When you create a VM Storage Policy, … [Read more...]

iSCSI IQN may have changed after working after upgrade to 7.0 U2

Last week I noticed some folks reporting that they had an issue with upgrades to 7.0 U2 from 7.0 U1. The issue they experienced was not being able to access their iSCSI Datastores any longer. I did some digging internally and found out there was a change in how we store the iSCSI IQN when the IQN is randomly created. … [Read more...]

How do I change the name of a vSwitch with vSphere 7.0 U2 and higher?

Some of you may have noticed it already, and some may not, but a lot of the configuration details that were traditionally stored in “esx.conf” have now moved elsewhere. The question is where did it go? Well it went into “configstore” and with “configstore” now also comes a … [Read more...]

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...]

Can 2-node or Stretched be used as client or server cluster with vSAN HCI Mesh?

I had this question today, probably sparked by my post earlier where a showed a single-node cluster being able to leverage HCI Mesh to mount a remote vSAN Datastore. The question was if this also works with 2-node vSAN or with a vSAN Stretched Cluster. Unfortunately, the answer is no, a 2-node cluster or a vSAN … [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...]

Using HCI Mesh with a stand-alone vSphere host?

Last week at the French VMUG we received a great question. The question was whether you can use HCI Mesh (datastore sharing) with a stand-alone vSphere Host. The answer is simple, no you cannot. VMware does not support enabling vSAN, and HCI Mesh, on a single stand-alone host. However, if you still want to mount a vSAN … [Read more...]

vSphere Native Key Provider backup not working

I had three people asking this question the past few weeks, they were trying to configure the vSphere Native Key Provider so that they could enable vSAN Encryption, but the backup function wasn’t working. If you have not seen the Native Key Provider in action yet, just watch the video below. As demonstrated in … [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...]

Compute only HCI Mesh with vSAN 7.0 U2

I guess that title explains it all, starting with vSAN 7.0 U2, we now also support connecting a compute-only cluster with a vSAN cluster. Meaning that if you have a vSphere cluster that does not have vSAN enabled, you can now mount a remote vSAN Datastore to it and leverage all the capabilities it provides! I am sure … [Read more...]
