Service Provider Requirements

Before you install vCloud Director Extender, verify that you fulfill the product release, licensing, network, and access requirements.

Product Release and Licensing Requirements

Products	Requirements
vCloud Director	For information about the interoperability between vCloud Director and vCloud Director Extender, see VMware Product Interoperability Matrices.
NSX	The interoperability between NSX and vCloud Director Extender depends on the interoperability between vCloud Director and NSX. vCloud Director Extender supports all NSX versions that are interoperable with a supported vCloud Director version. For more information about the interoperability between NSX, vCloud Director, and vCloud Director Extender, see VMware Product Interoperability Matrices.
vSphere	For information about the interoperability between vCenter Server and vCloud Director Extender, see VMware Product Interoperability Matrices. VMware vSphere Essentials Plus Kit or above. To download the vCloud Director Extender OVA file, you must have a valid vSphere license.

Network and Access Requirements

Category	Requirements
Network	The network bandwidth between on-premises and vCloud Director VDC must be 100 Mbps or higher. Assign static IP addresses to the virtual machines hosting vCloud Director Extender components and services. vCloud Director Extender does not run any preliminary checks to verify the validity of the static IP configurations that you provide during the configuration. Important: vCloud Director Extender does not support DHCP network configuration. The CX Cloud Service appliance must be configured with a DNS server IP. Based on the source and destination networks, the number of edges deployed can vary. A best practice for configuring DC Extension in the service provider environment is to use an XL-Edge with 8 GB RAM, 6 CPUs, and 500 MB disk space.
User Access	For vCloud Director, a cloud administrator user with specific permissions is required. For more information, see Set Up Authorization for Organization Administrator User. For the Resource vCenter Server and Management vCenter Server instances, vi-admin permissions are required.
