Before you install an NSX Manager or other NSX-T Data Center appliances, make sure that your environment meets the supported requirements.

Supported Hypervisors for Host Transport Nodes

Hypervisor Version CPU Cores Memory
vSphere Supported vSphere version 4 16 GB
CentOS Linux KVM 7.9, 8.4 4 16 GB
Red Hat Enterprise Linux (RHEL) KVM 7.9, 8.2, 8.4 4 16 GB
SUSE Linux Enterprise Server KVM 12 SP4 4 16 GB
Ubuntu KVM 18.04.2 LTS, 20.04 LTS 4 16 GB
Note: To avoid memory errors on a hypervisor host running vSphere ESXi version 7.x.x, ensure that at least 16 GB is available before deploying NSX Manager.
Table 1. Supported Hosts for NSX Managers
Support Description Hypervisor
ESXi For supported hosts, see the VMware Product Interoperability Matrices.
KVM RHEL 7.7 and Ubuntu 18.04.2 LTS

For ESXi hosts, NSX-T Data Center supports the Host Profiles and Auto Deploy features on vSphere 6.7 EP6 or higher. See Understanding vSphere Auto Deploy in the VMware ESXi Installation and Setup documentation for more information.

Caution: On RHEL and Ubuntu, the yum update command might update the kernel version, which must not be greater than 4.19.x, 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

The NIC card used must be compatible with the ESXi version that is running NSX-T Data Center. For supported NIC card, see the VMware Compatibility Guide. To find the supported driver for the NIC card vendor, see Firmware Versions of Supported Drivers.
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.

NSX Manager VM Resource Requirements

Thin virtual disk size is 3.8 GB and thick virtual disk size is 300 GB.

Appliance Size Memory vCPU Shares Reservations Disk Space VM Hardware Version
NSX Manager Extra Small (NSX-T Data Center 3.0 onwards) 8 GB 2 81920, Normal 8192 MB 300 GB 10 or later
NSX Manager Small VM ( NSX-T Data Center 2.5.1 onwards) 16 GB 4 163840, Normal 16384 MB 300 GB 10 or later
NSX Manager Medium VM 24 GB 6 245760, Normal 24576 MB 300 GB 10 or later
NSX Manager Large VM 48 GB 12 491520, Normal 49152 MB 300 GB 10 or later
Note: 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 provide by the NSX Controller appliance.

  • You can use the Extra Small VM resource size only for the Cloud Service Manager appliance (CSM). Deploy CSM in the Extra Small VM size or higher, as required. See Overview of Deploying NSX Cloud for more information.

  • 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 the autoselected appliance size during deployment and is suitable for typical production environments. An NSX-T management cluster formed using this appliance size can support up to 128 hypervisors. Starting with NSX-T 3.1, a single NSX Manager cluster is supported.

  • The NSX Manager Large VM appliance size is suitable for large-scale deployments. An NSX-T management cluster formed using this appliance size can support more than 128 hypervisors.

For maximum scale using the NSX Manager Large VM appliance size, go to the VMware Configuration Maximums tool at https://configmax.vmware.com/guest and select NSX-T Data Center from the product list.

Language Support

NSX Manager has been localized into multiple languages: English, German, French, Japanese, Simplified Chinese, Korean, Traditional Chinese, and Spanish.

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 80 Yes Yes Yes
Mozilla Firefox 72 Yes Yes Yes
Microsoft Edge 80 Yes
Apple Safari 13 Yes
Note:
  • 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 utilizes 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 disk access latency is under 10ms.
  • It is recommended that NSX Managers be placed on shared storage.
  • Storage must 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.
