Goodbye NSX-T, welcome NSX!

On 2nd of August VMware released new version of NSX with number as major release. Along new version number, the product name has changed also. From “VMware NSX-T Data Center” to “VMware NSX.” This new name better reflects the multi-faceted value that NSX brings to customers.

This update is apparent in the product graphical user interface as well as documentation. This change has no impact to the functionality of the product or changes to the API that impacts compatibility with previous releases.

Let’s have a look at major enhancements which the new version of NSX will bring to us:

  • IPv6 external-facing Management Plane introduces support for IPv6 communication from external systems with the NSX management cluster (Local Manager only).
  • Block Malicious IPs in Distributed Firewall is a new capability that allows the ability to block traffic to and from Malicious IPs.
  • NAT support for Policy-based VPN on T0/T1 Gateway allows the configuration of DNAT/NO-DNAT rule that matches traffic decapsulated from the Policy-based VPN.
  • DHCP UI configuration workflow improvement offers in a simpler and easier configuration of Local DHCP server; Gateway DHCP server or DHCP Relay . It also offers better visibility and monitoring options.
  • DHCP Standby relocation improves the availability for the DHCP server, allowing the configuration of standby relocation where, in case of failure, the new standby Edge will be elected.
  • Edge relocate API gives the option when an Edge VM enters maintenance mode, to gracefully relocate all T1 auto allocated SRs to other Edge VMs.
  • Maintain Edge Node parameters during upgrade – post-upgrade all user-edited settings of Edge Node will be preserved and not reset to default.
  • Faster Upgrades – benefit from up to a 10% reduction in NSX upgrade time overall to use the maintenance windows more effectively.
  • Live Traffic Analysis & Traceflow support for VPN – get an end-to-end view of live packets in a VPN tunnel using Traceflow or the Live Traffic Analysis Tool

NSX will no longer support either KVM based hypervisors or OpenStack distributions from third-party vendors. Support for VMware Integration OpenStack (VIO) remains. Please see the VMware Product Interoperability Matrix for details on which versions of NSX and VIO are compatible.

NOTE: Please be aware that VMware has removed support of the NSX N-VDS virtual switch on ESXi hosts starting this release, NSX N-VDS will remain the supported virtual switch on NSX Edge nodes, native public cloud NSX agents, and bare metal workloads.

There are also changes to API. Please follow this document to read more:

For compatibility and system requirements information, see the VMware Product Interoperability Matrices and the NSX Installation Guide.

For instructions about upgrading NSX components, see the NSX Upgrade Guide.

Customers upgrading to this release are recommended to run the NSX Upgrade Evaluation Tool before starting the upgrade process. The tool is designed to ensure success by checking the health and readiness of your NSX Managers prior to upgrading.
