In vSphere 6.5 the smallest supported memory configuration for the vCenter Server Appliance has been raised from 8GB to 10GB. The smallest "Tiny" deployment size allows up to 10 ESXi Hosts and 100 Virtual Machines. Resources in Homelabs are limited and you might want to lower the memory consumption of the vCenter Servcer Appliance. This article explains how to lower the resource consumption to be able to lower the memory to about 6GB without noticable impacts.

USB Devices as VMFS Datastore in vSphere ESXi 6.5

In ESXi 6.5, there are some changes concerning devices connected with USB. The legacy drivers, including xhci, ehci-hcd, usb-uhci, and usb-storage have been replaced with a single USB driver named vmkusb. The new driver has some implications if you are trying to use USB devices like USB sticks or external hard disks as VMFS formatted datastore.
Some people have reported that they have issues with USB Datastores since ESXi 6.5. I've tried to reproduce and fix those problems. This post explains the changes in the new version and how to create VMFS 5 or VMFS6 formatted USB devices as datastore on your ESXi host. Read more »
Deploy VMware NSX in Homelabs with Limited Resources

When deploying VMware NSX in a homelab, its huge resource requirement might be an issue. In the default configuration a small setup with NSX Manager, 3 NSX Controllers and 2 Edge gateways requires 30 GB Memory. Consumer VMs to connect to logical switches requiring additional resources.
This post explains how you can deploy VMware NSX in your homelab with less than 8GB Memory by downsizing each component including:
- NSX Manager
- NSX Controllers
- NSX Edge Gateways
- Consumer VMs
VMware NSX 6.2 Beginners Guide - From Zero to Full Deployment for Labs

VMware NSX is the SDDC technology of the future. What ESX was once for Servers, NSX is now for Networks. I highly encourage everyone to make yourselves familiar with this technology. NSX with all its features is quite complex, but the entry point is quite simple and requires only basic vSphere and networking skills. This beginners guide explains how to deploy NSX in your homelab even with limited physical ressources by downsizing NSX Manager and NSX Controller VMs. The guide starts at zero and quickly explains how to deploy NSX and connect your first Virtual Machine to a VXLAN based logical switch that is able to communicate to the physical world through an NSX Edge Gateway.
What do you need to create the Lab?
- vCenter 6 with some physical ESXi Hosts
- vSphere Distributed Switch (dvSwitch)
- NSX Manager Appliance (Download: NSX 6.2.2)
- There is no special physical Switch requirement
VMware Host Client (HTML5 based Web-Client) on Android

The VMware Host Client is a HTML5 client that is used to connect to and manage single ESXi hosts without a vCenter Server. The Host client was initially created as a Fling, but made it to a supported component of vSphere 6.0 Update 2.
No Flash, no Windows-based C# Client - Shouldn't it work on Android based smartphones and tablets? I've tried to manage a standalone Homelab ESXi Host with the Web-based Host Client and it works quite nice (with some tweaking).
Of Course, it's not suitable for large platforms, as the vCenter Web-Client is still Flash based.
USB Devices as VMFS Datastore in vSphere ESXi 6.0

In the last years I've seen many requests in forums and blogs where people are trying to use USB devices like USB sticks or external hard disks as VMFS formatted datastore. It was actually possible in vSphere 5, but very picky. Some USB flash drives were working, others not. In vSphere 6, this behavior has been changed obviously. This post explains how you can use USB devices as datastore on your ESXi host. Of course, this is neither a supported, nor a performant storage solution, so use at your own risk. Read more »
