Before you install an NSX Manager, make sure that your environment meets the supported requirements.

Hypervisor Host Requirements for Transport Nodes

Hypervisor Version CPU Cores Memory
vSphere Supported vSphere version 4 16 GB
CentOS Linux KVM 7.4 4 16 GB
Red Hat Enterprise Linux (RHEL) KVM 7.6, 7.5, and 7.4 4 16 GB
SUSE Linux Enterprise Server KVM 12 SP3, SP4 4 16 GB
Ubuntu KVM 18.04 and 16.04.2 LTS 4 16 GB
Table 1. Supported Hosts for NSX Managers
Support Description Hypervisor
ESXi For supported hosts, see the VMware Product Interoperability Matrices.
KVM 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 later. See Understanding vSphere Auto Deploy in the VMware ESXi Installation and Setup documentation for more information.

Caution: 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.

Hypervisor Host Network Requirements

It is required that hypervisor hosts running NSX-T Data Center have a compatible NIC card. For supported NIC cards, see the VMware Compatibility Guide.
Tip: To quickly identify compatible cards in the Compatibility Guide, apply the following criteria:
  • Under I/O Device Type, select Network.
  • Optionally, to use supported GENEVE encapsulation, under Features, select the GENEVE options.
  • Optionally, to use Enhanced Data Path, select N-VDS Enhanced Data Path.

Enhanced Data Path NIC Drivers

Download the supported NIC drivers from the My VMware page.

Intel(R) Ethernet Controller X710 for 10GbE SFP+

Intel(R) Ethernet Controller XL710 for 40GbE QSFP+


NSX Manager VM Resource Requirements

Thin virtual disk size is 3.8 GB and thick virtual disk size is 200 GB.

Appliance Size Memory vCPU Disk Space VM Hardware Version
NSX Manager Extra Small 8 GB 2 200 GB 10 or later
NSX Manager Small VM 16 GB 4 200 GB 10 or later
NSX Manager Medium VM 24 GB 6 200 GB 10 or later
NSX Manager Large VM 48 GB 12 200 GB 10 or later
Note: As of NSX-T 2.4, the NSX Manager provides multiple roles which previously required separate appliances. This includes the policy role, the management plane role, and the central control plane role. The central control plane role was previously provided by the NSX Controller appliance.
  • 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 NSX-T Data Center from the product list.

NSX Manager Browser Support

The following browsers are recommended for working with NSX Manager.

Browser Windows 10 Mac OS X 10.13, 10.14 Ubuntu 18.04
Google Chrome 76 Yes Yes Yes
Mozilla Firefox 68 Yes Yes Yes
Microsoft Edge 44 Yes
Apple Safari 12 Yes
  • Internet Explorer is not supported.
  • Supported Browser minimum resolution is 1280 x 800 px.
  • Language support: NSX Manager has been localized into multiple languages: English, German, French, Japanese, Simplified Chinese, Korean, Traditional Chinese, and Spanish. However, because NSX Manager localization uses the browser language settings, ensure that your settings match the desired language. There is no language preference setting within the NSX Manager interface itself.

Network Latency Requirements

The maximum network latency between NSX Managers in a NSX Manager 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.

    Consult the documentation for your storage technology on how to best design a highly available storage solution.
