Quick Tip - How to download ESXi ISO image for all releases including patch updates?

by // 9 Comments

Not all ESXi releases, including patch updates are available as an ISO image that can be downloaded. Depending on the type of ESXi release, it will either be available as an ISO and Offline Bundle (zip) format which can downloaded from the ESXi Customer Connect portal or only as an Offline Bundle which must be downloaded from the VMware Patch portal.

I typically see folks forgetting about the VMware Patch portal, which also provides patch updates for the vCenter Server Appliance (VCSA), when they are searching for a new ESXi updates. Let's take a look at an example using the ESXi 7.0 Update 3 release, as you can see from the screenshot below, you can download 7.0 Update 3c, d, f and g from the Customer Connector portal but for 7.0 Update 3e, i, j and k you will need to use the VMware Patch portal.


As mentioned earlier, when downloading ESXi patches from the VMware Patch portal, they are only available in the Offline Bundle format, which might work for most typical patch use cases but in some scenarios, you may actually want it in an ISO format, especially for initial installation.

SSD with multiple NVMe namespaces for VMware Homelab

by // Leave a Comment

If space is a constraint for your VMware Homelab, you may want to consider using SSDs that can support multiple NVMe Namespaces. I first came to learn about NVMe namespaces and its benefits back in 2019 when it was first demonstrated by Micron and using it vSAN, which was also the primary use case I had in mind.

While interesting, I eventually concluded that support for multiple NVMe namespaces was only available in higher-end Enterprise SSDs, which is typically outside of the affordability range for most homelab environments. Another challenge that I found with SSDs that supported multiple NVMe namespaces, is that the interface uses a U.2 connector versus the popular M.2, which is what you would typically find in a homelab setup. This also limited the applicability of these SSDs as you would need a motherboard with a U.2 interface.

I recently had revisited the topic of NVMe namepaces as I came across the PM9A3 from Samsung, which not only supported multiple NVMe namespaces, but it was also reasonable priced ($143 for 960GB at the time of purchase). My ultimate goal was to see if I could use the 2.5" SSD in a small form factor system that only has an M.2 slot and slice up the NVMe namespace for ESXi installation + ESX-OSDATA, vSAN and even additional VMFS volumes.

Is my vSphere Cluster managed by vSphere Lifecycle Manager (vLCM) as a Desired Image or Baseline?

by // 11 Comments

Prior to vSphere 7.0, ESXi lifecycle management has been provided by vSphere Update Manager (VUM), which has been around for more than a decade plus and is most likely what you are still using today. With the release of vSphere 7.0, VMware introduced a brand new lifecycle management solution for ESXi called vSphere Lifecycle Manager (vLCM), which you can read more about HERE.


While VMware has made it clear that vLCM will be the future going forward for ESXi lifecycle management, we also understand that most customers will still be using the existing VUM-based solution and we wanted to make sure it was easy to  transition between the two solutions, especially within the vSphere UI.

An interesting question was recently brought up was how to determine whether a vSphere Cluster was using the new vLCM solution based on desired images versus VUM, which uses baselines?

Note: If you are not familiar between vLCM Desired Image and VUM Baselines, be sure to check out this helpful resource HERE.
