|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|
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.
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|
- 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.
- 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.
