Sharing a single NVMe device with NVMe Tiering? 

by // 4 Comments

I am a huge fan of the new NVMe Tiering capability within vSphere 8.0 Update 3 and it has been fantastic to hear more users taking advantage of this new feature to see what it can do for their homelab/development setup but also for their various production workloads.

As of right now, enabling NVMe Tiering requires a dedicated NVMe device, which for a production system is probably acceptable as you will probably want to ensure there are no other workloads competing for IO on the NVMe device. However, for a development environment or homelab, this can be challenge due to number of available NVMe devices that can be used.

Thank you to fellow reader Andrea T, for sharing this awesome tidbit with the community and how you CAN actually share a single NVMe device with NVMe Tiering! 😍

New ESXi-Arm Fling based on 8.0 Update 3b

by // 22 Comments

I am very happy to share that the ESXi-Arm team has just released a brand new version of the popular ESXi-Arm Fling (v2.0), which is now based on ESXi 8.x codebase and specifically using the latest ESXi-x86 8.0 Update 3b release! This is a very exciting update, as the original release of the ESXi-Arm Fling (released 4 years ago this month) has been based on the ESXi 7.x codebase for its initial port from x86 to Arm.

After delivering the initial productization of ESXi-Arm with the release of vSphere Distributed Service Engine (vDSE), formally known as Project Monterey, the ESXi-Arm team has been hard at work to converge the ESXi-Arm codebase, which is also used powers our vDSE technology!


In addition to porting the ESXi-Arm codebase from 7.x to 8.x, the team continues to support a large variety of Arm-based systems, which you can see from the list below:

Useful NVMe Tiering reporting using vSphere 8.0 Update 3 APIs

by // 2 Comments

After successfully enabling the NVMe Tiering feature, which was introduced in vSphere 8.0 Update 3, you can find some useful details about your NVMe Tiering configuration by navigating to a specific ESXi host and under Configure->Hardware and under the Memory section as shown in the screenshot below.


There is quite a bit of information that we can see, so lets break down the individual items that are useful from an NVMe Tiering point of view and the specific vSphere APIs that can be used to retrieve this information.
