NSX 6.4.1 Now Available!

On May 24th, VMware released NSX 6.4.1 – the first version of NSX to support vSphere 6.7. This is undoubtedly exciting news for those who have been waiting to upgrade their vSphere deployment. Although 6.4.1 sounds like a minor release, there are a slew of UI and usability enhancements as well as context-aware firewall improvements. There has also been some additional functionality introduced into the HTML5 client, which is very welcome news.

You’ll also notice in 6.4.1 that the service composer canvas view has been removed. This was a bit of an iconic overview page for service composer in the UI, but was not terribly useful and didn’t scale at all to large deployments with many security policies. I honestly don’t think anyone will be missing it.

On top of these enhancements, VMware engineering has been busy with bug fixes. NSX 6.4.1 includes 23 documented fixes across all areas of the product. A couple of notable ones include:

  • Fixed Issue 2035026: Network outage of around 40-50 seconds seen on Edge Upgrade
  • Fixed Issue 1971683: NSX Manager logs false duplicate IP message
  • Fixed Issue 2092730: NSX Edge stops responding with /var/log partition at 100% disk usage
  • Fixed Issue 1809387: Support for Weak Secure transport protocol – TLS v1.0 removed

You can find the complete list in the resolved issues section of the NSX 6.4.1 release notes.

Planning to upgrade? Remember to check the NSX upgrade matrix. Those running 6.2.0, 6.2.1 or 6.2.2 will need to refer to KB 51624 before upgrading. Have a look at my ‘Ten Tips for a Successful NSX Upgrade‘ post for ways to ensure your upgrade is successful.
