VMware has published a patch for ESXi 6.5 and the corresponding vCenter Server version. This patch [..l}] and is the first 6.5 release to support VMware NSX.

Last week VMware has silently removed the download for the latest version of VMware NSX. Today the Support Insider blog, which is a great resource for first-hand field experience, reported that the NSX for vSphere 6.2.3 release has been officially pulled.
- Distributed Firewall Issue in NSX 6.2.3 (Virtual machines with Distributed Firewall (DFW) and Security Groups (SG) configured may encounter traffic disruption after a vMotion followed by changes to configuration of the Global Address Sets in the SG referenced for that virtual machine)
DFW rules using SG not correctly being applied to VMs (KB2146227)
- ARP Issues with Windows VMs in NSX 6.2.x (When the pMAC of DLR is the MAC address in the default gateway instead of generic DLR MAC address, windows virtual machines loose network connectivity)
Virtual machines lose network connectivity in NSX 6.2.x (2146293)
VMware recommends to suspend updates until the replacement for NSX 6.2.3 is released.
Intel NUCs with ESXi are a proven standard for virtualization home labs. I'm currently running a homelab consisting of 3 Intel NUCs with a FreeNAS based All-Flash Storage. If you are generally interested in running ESXi on Intel NUCs, read this post first. One major drawback is that they only have a single Gigabit network adapter. This might be sufficient for a standalone ESXi with a few VMs, but when you wand to use shared Storage or VMware NSX, you totally want to have additional NICs.
A few month ago, this problem has been solved by an unofficial driver that has been made available by VMware engineer William Lam.
VMware has release an update for their network virtualization platform NSX. Together with some minor changes to the product itself, VMware announced that all users with a NSX 6.2.3 (and beyond) license are now entitled to vRealize Log Insight for NSX at no additional charge.

What's new in VMware NSX 6.2.3
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
For network analysis I want to have Distributed Switch port statistics in my Graphite installation. I’ve created a script that pulls dvSwitch port statistics from a vCenter server, or directly from an ESXi host and sends them to a Carbon Relay. Ports connected to NSX Logical Switches, which are actually distributed Port Groups, are also included. This allows to create universal dashboards with Grafana for example.
This script is intended to run as cronjob every minute. Port Statistics are provided as counters which can be easily converted to per second values with Graphite functions.
To monitor VMware NSX Edge Gateways I want to send interface statistics to my Graphite installation. NSX Manager comes with a REST API that allows to pull information in XML or JSON format. I've created a script that pulls Interface, Firewall and Load Balancer statistics from all ESGs and sends them to a Carbon Relay. This allows to create universal custom dashboards with Grafana for example.
An Edge Services Gateway allows to connect services running on Logical Switches outside of NSX based networks. I've explained the base installation from zero to the first ESG here. This post explains how to connect Web servers running on logical networks VXLAN to the outside.
In this example I'm running 3 nginx web servers on small Linux appliances connected to a logical switch.
