Quick Tip - New remote version of ESXCLI 8.x

by // 1 Comment

I was recently made aware of a nice update from our developers that we now have a new version of the remote ESXCLI utility that is much simpler to install across any operating system and is fully backwards compatibility with ESXi hosts running 6.7.x, 7.x and 8.x.

Many of you are probably familiar with the local version of ESXCLI which is available when connecting to ESXi whether that is over SSH or directly in the ESXi Console. However, a remote version of ESXCLI has been available since the introduction of ESXCLI back in vSphere 4.0, but surprisingly, I still come across users who never knew that this was possible!

In the past, the remote version of ESXCLI was platform specific and it was distributed in a number of diffrent ways from being bundled as part of the vSphere CLI (6.7) to being a standalone download (7.0) and this inconsistency brought many challenges, not just from an internal development standpoint but also operationally for users who needed to deploy this utility across their administrative systems.

What is vc-ws1a-broker service on vCenter Server Appliance (VCSA)?

by // 2 Comments

When vSphere 8.0 Update 1 was released, I noticed an interesting message about containers being installed while deploying the vCenter Server Appliance (VCSA) ...

As shared in the Tweet/X above, it turns out this was for a service called vc-ws1a-broker, which I came to learn was for enabling the new Identity Federation Provider for the VCSA with Okta.

I ended up correctly guessing that the vc-ws1a-broker process was indeed our very own VMware Workspace One Access (WS1A) application but running as a Container workload within the VCSA. In vSphere 8.0 Update 2, support for Microsoft EntraID (formally Azure AD) is now also possible as additional identity provider option.

One important thing to be aware of the vc-ws1a-broker service is that it is configured to be able to consume up to 2GB of memory, as shown using the cloudvm-ram-size utility in the screenshot below.

Support for read-only VMDK in vSphere 8.0 Update 2

by // 3 Comments

vSphere 8.0 Update 2 was just announced last week at VMware Explore and it brings a lot of exciting new capabilities, check out this What's New in vSphere 8.0 Update 2 and What's New in vSAN 8.0 Update 2 blog posts for a nice summary of all the new features.

While doing some testing in my vSphere 8.0 Update 2 lab, I came to learn about a really cool feature that has been requested by customers over the years, which is the ability to configure a read-only virtual disk (VMDK). The most common use case for this feature is being able to share a single VMDK across multiple Virtual Machines and prevent any changes to the original data, a common scenario for VMware App Volumes or VMware Horizon environments.

I could also see this capability get leveraged by users as a way to distribute and install software where traditional application management systems are unavailable but still ensuring that workloads can not manipulate or modify the original files, definitely opens the door for some interesting capabilities.
