Licensing

Order either the Advanced or Enterprise Plus editions of VMware NSX-T Data Center for use on the VxBlock System. The VMware NSX-T Data Center data sheet provides a detailed breakdown of each edition and the features that are supported . In VMware NSX-T Data Center, the physical Edge hosts and all transport nodes participating in NSX need to be licensed for each physical CPU socket.

You can license any number of transport nodes (compute hosts). Consider the following:

  • The licensed transport nodes can be a subset of the physical hosts in the VxBlock System.
  • The licensed transport nodes could be more hosts than physically exist in the system. Licensing more hosts in this way enables you to stretch overlay-backed segments across multiple VxBlock Systems.
  • All physical edge hosts must be licensed for NSX, even though they are not prepared as transport nodes.
  • All VMware NSX-T Data Center licensing must be purchased directly through VMware. Dell EMC is unable to resell the licensing for the product due to export compliance issues.

Cisco UCS licensing

The licensing that is required to connect the physical edge hosts to the UCS domain varies depending on the following:

  • The type of Cisco UCS domain to which the hosts are connecting
  • Whether there is a FEX connected to the FIs

The various connectivity models and their licensing requirements are detailed in the following table:

Connectivity model Licensing details
Cisco UCS third-generation domain (Cisco UCS 6332-16UP Fabric Interconnects), no FEX Each QSFP port on a Cisco UCS third-generation FI used for VMware NSX-T Data Center edge direct-connect should be licensed using the direct-connect SKU UCS-LIC-6300-40GC.

Two edge hosts require two SKUs.

Four, six, or eight hosts require four SKUs. 

More than eight edge hosts require eight SKUs.

Cisco UCS fourth-generation domain (Cisco UCS 6400 Series Fabric Interconnects), no FEX Each edge compute host that connects directly to a Cisco UCS fourth-generation FI must be licensed to connect to the Cisco UCS domain. The license is the Cisco UCS C-Series Rack Server only 25 Gbps SKU (UCS-LIC-6400-25GC), quantity two ports per server.
Any Cisco UCS domain with FEX Any edge compute host that connects to a FEX and not to an FI does not need any additional port licensing.

VMware ESXi licensing

Each physical edge host consumes standard per-socket CPU licensing for VMware ESXi. In this configuration, each host has two physical CPU sockets that are populated, and consumes two VMware ESXi CPU licenses.
