Table 1. Supported Hosts for NSX Managers

Support Description



For supported hosts, see the VMware Product Interoperability Matrices.


RHEL 7.4 and Ubuntu 16.04 LTS

For ESXi hosts, NSX-T Data Center supports the Host Profiles and Auto Deploy features on vSphere 6.7 U1 or higher. See "Understanding vSphere Auto Deploy" in the VMware ESXi Installation and Setup for more information.


On RHEL, the yum update command might update the kernel version and break the compatibility with NSX-T Data Center. Disable the automatic kernel update when you run yum update. Also, after running yum install, verify that NSX-T Data Center supports the kernel version.

  • The NSX Manager Extra Small VM resource requirements apply only to the Cloud Service Manager.

  • The NSX Manager Small VM appliance size is suitable for lab and proof-of-concept deployments, and must not be used in production.

  • The NSX Manager Medium VM appliance size is suitable for typical production environments and can support up to 64 hypervisors.

  • The NSX Manager Large VM appliance size is suitable for large-scale deployments with more than 64 hypervisors.

For maximum scale using the NSX Manager Large VM appliance size, go to the VMware Configuration Maximums tool at and select VMware NSX-T from the product list.

NSX Management Clustering Requirements

  • In a production environment, the NSX Management cluster must have three members to avoid an outage to the management and control planes.

    Each cluster member should be placed on a unique hypervisor host with three physical hypervisor hosts in total. This is required to avoid a single physical hypervisor host failure impacting the NSX control plane.

    The normal production operating state is a three-node NSX Management cluster. However, you can add additional, temporary NSX Managers to allow for IP address changes.


    As of NSX-T 2.4, the NSX Manager contains the NSX Central Control Plane process. This service is critical for the operation of NSX. If there is a complete loss of NSX Managers, or if the cluster is reduced from three NSX Managers to one NSX Manager, you will not be able to make topology changes to your environment, and vMotion of machines depending on NSX will fail.

  • For lab and proof-of-concept deployments where there are no production workloads, you can run a single NSX Manager to save resources. NSX Managers can be deployed on either ESXi or KVM. However, mixed deployments of managers on both ESXi and KVM are not supported.

  • A given NSX Management cluster is designed to run in a single site. NSX Managers in a single NSX Management cluster should not be deployed in different physical data centers.

NSX Manager Browser Support


Windows 10

Windows 8.1

Ubuntu 14.04

Mac OS X 10.11. 10.12

Internet Explorer 11



Firefox 55



Chrome 60




Safari 10


Microsoft Edge 40



Internet Explorer 11 in compatibility mode is not supported.

Supported Browser minimum resolution is 1280 x 800 px.

Network Latency Requirements

The maximum network latency between NSX Managers in a NSX Management cluster is 10ms.

The maximum network latency between NSX Managers and Transport Nodes is 150ms.

Storage Requirements

  • The maximum disk access latency is under 10ms.

  • It is recommended that NSX Managers be placed on shared storage.

  • Storage should be highly available to avoid a storage outage causing all NSX Manager file systems to be placed into read-only mode upon event of a storage failure.

    Please consult documentation for your storage technology on how to best design a highly available storage solution.
