Before you install or upgrade NSX, consider your network configuration and resources. You can install one NSX Manager per vCenter Server, one instance of Guest Introspection and Data Security per ESXi™ host, and multiple NSX Edge instances per datacenter.

*As a general guideline, if your NSX managed environment contains more than 256 hypervisors, we recommend increasing NSX Manager resources to 8 vCPU and 24 GB of RAM. For specific sizing details contact VMware support.

For information about increasing the memory and vCPU allocation for your virtual appliances, see the following vSphere documentation pages (or the equivalent pages for your version of vSphere):


For the latest interoperability information, see the Product Interoperability Matrixes at

These are the recommended versions of VMware products.

  • VMware vCenter Server 5.5U3

  • VMware vCenter Server 6.0U2


VMware vCenter Server 6.x is required for cross-vCenter NSX.

Note that for an NSX Manager to participate in a cross-vCenter NSX deployment the following conditions are required:



NSX Manager

6.2 or later

NSX Controller

6.2 or later

vCenter Server

6.0 or later


  • ESXi 6.0 or later

  • Host clusters prepared with NSX 6.2 or later VIBs

To manage all NSX Managers in a cross-vCenter NSX deployment from a single vSphere Web Client, you must connect your vCenter Servers in Enhanced Linked Mode. See the VMware vSphere 6 Documentation
