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 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...]

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...]

How long does it take before a host is declared failed?

I had a question this week around the failure of a host. The question was how long it takes before a host is declared failed. Now let’s be clear, failed means “dead” in this case, not isolated or partitioned. It could be the power has failed, the host has gone completely unresponsive, or anything else … [Read more...]

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...]

Is a crossover cable needed for vSAN 2-Node Direct Connect?

I had this question last week around vSAN 2-node direct connect and whether using a crossover cable is still required to be used or if a regular CAT6 cable (CAT 5E works as well) can be used. I knew the answer and figured this would be documented somewhere, but it doesn’t appear to be. To be honest, many websites … [Read more...]

Can’t have more than 255 characters in VM notes using the vSphere (h5) Client?

I had a question about a limit a customer was hitting with the VM notes using the vSphere (H5) Client. They noticed that whenever they got around ~260 or so characters, they could not add any characters beyond that unless they deleted some. After talking to an engineer within VMware I found out that this is indeed the … [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...]
