VMware vSAN on Consumer-Grade SSDs - Endurance analysis

When you are running an ESXi based homelab, you might have considered using vSAN as the storage technology of choice. Hyperconverged storages are a growing alternative to SAN-based systems in virtual environments, so using them at home will help to improve your skillset with that technology.

To get started with vSAN you need at least 3 ESXi Hosts, each equipped with 2 drives. Alternatively, you can build a 2-node vSAN Cluster using a Raspberry Pi as a witness node.

VMware maintains a special HCL that lists supported drives to be used with vSAN. In production setups, it is very important to use certified hardware. Using non-enterprise hardware might result in data loss and bad performance caused by the lack of power loss protection and small caches.

This article takes a look at consumer-grade SSDs and their durability to be used with vSAN. Please be aware that non-certified hardware should only be used in homelabs or for demo purposes. Do not place sensitive data on vSAN that is running on consumer hardware.

Tanzu Kubernetes Licensing in vSphere 7.0 Update 1

With the release of vSphere 7.0 Update 1, VMware introduced a new licensing model for its Tanzu Kubernetes integration. Basically, the licensing has been changed from an ESXi-Host license to a Cluster license that looks familiar to the vSAN license which is in place for a couple of years. The change does only affect how you have to apply the license. The entity to pay for is still a physical CPU.

In vSphere 7.0 GA, the license required to enable Kubernetes (aka. "Workload Management") was an add-on license for ESXi Hosts named "vSphere 7 Enterprise Plus with Kubernetes". With the introduction of vSphere 7.0 Update 1, which is also referred to as 7.0.1, "vSphere add-on for Kubernetes" has been rebranded and split into 4 licenses Tanzu Basic, Tanzu Standard, Tanzu

Update ESXi 7.0 with VMKUSB NIC Fling to 7.0 Update 1

The USB Native Driver Fling, a popular ESXi driver by Songtao Zheng and William Lam that adds support for USB-based Network Adapters, has been updated to version 1.7. The new version has added support for vSphere 7.0 Update 1.

When you download the latest version, you notice that there are separate versions for 7.0 and 7.0 U1. Both versions are only compatible with their corresponding ESXi version, which makes direct updates a little bit more complex.

This article explains how to upgrade ESXi hosts with USB-based network adapters in a single step.

Tips for using USB Network Adapters with VMware ESXi

Running Intel NUCs and other SFF systems with ESXi is a proven standard for virtualization home labs. One major drawback is that most of the available SFF systems only have a single Gigabit network adapter. This might be sufficient for a standalone ESXi with a few VMs, but when you want to use shared Storage or VMware NSX, you totally want to have additional NICs.

This article explains some basics to consider when running USB-based network adapters with ESXi.

ESXi VMKUSB NIC Fling adds support for 2.5GBASE-T Adapters

The USB Native Driver Fling, a popular ESXi driver by Songtao Zheng and William Lam that adds support for USB-based Network Adapters, has been updated to version 1.6. The new version has added support for RTL8156 based 2.5GBASE-T network adapters.

Multi-Gigabit network adapters with 5GBASE-T are available for a while, but those 5GbE adapters cost about $100 USD. The new driver allows the usage of 2.5GbE adapters that are available for as low as $25 USD. The driver was released yesterday, and luckily I already own a bunch of 2.5GbE adapters, so I could give it a test drive immediately.

How to add AD Authentication in vCenter 7.0

The vCenter Server has an internal user database that allows you to add and manage users very easily. Users management and Single Sign-On is provided by the embedded Platform Service Controller which is available since vSphere 6.0. In a large environment, you might want to connect your virtualization infrastructure to a centrally manage Active Directory.

This article explains how to add AD authentication in vSphere 7.0 and how to get the "Use Windows session authentication" checkbox to work with the "Enhanced Authentication Plugin".
