Preparing for a Successful HCX Deployment: Understanding Prerequisites and Requirements
As a seasoned System Engineer in the Information Technology field, I have always been fascinated by virtualization technology and its potential to revolutionize the way we deploy and manage IT infrastructure. In my journey so far, I have had the opportunity to work with various virtualization platforms, including VMware’s Software Defined Data Center (SDDC) solutions. One of the most exciting projects I have worked on is the deployment of VMware HCX (Hyper-Converged Infrastructure), which has allowed me to dive deeper into the world of hyper-convergence and cloud computing.
In this blog post, I will share my experience and knowledge of the prerequisites and requirements for deploying HCX in a production environment. Before we begin, it is essential to understand that the hardware requirements for HCX may change with different versions, so it’s always recommended to check the latest requirements by visiting System Requirements for HCX.
Prerequisites for HCX Deployment
——————————-
Before we can proceed with the deployment of HCX, there are several prerequisites that must be in place. These include:
1. Hardware Requirements: The resources below are required for deploying the HCX Managers and service appliances in source and destination environments up to the current HCX 4.5 version:
* 2 vCPUs (minimum)
* 4 GB RAM (minimum)
* 10 Gb Ethernet (recommended for optimal performance)
* SSD or NVMe storage (recommended for optimal performance)
2. Network Requirements: For a successful HCX deployment, a list of ports must be enabled for communication between services on the HCX appliances, and between HCX peers at the source and destination sites. The following ports must be allowed in HCX deployments:
* TCP 443 (default)
* TCP 80 (default)
* UDP 4172 (default)
* UDP 4173 (default)
3. NSX Requirements: For on-premises HCX deployments, NSX must be installed and configured before deploying HCX. NSX is not required for the source site (HCX Connector installations), except when extending NSX networks. While the destination site (HCX Cloud Manager installations) mandates to have the current NSX-T (or NSX for vSphere) deployed, and meeting all the requirements listed in this link.
Understanding HCX Network Ports and Protocols
———————————————-
To ensure a successful HCX deployment, it’s essential to understand the network ports and protocols used by HCX services. The following is a list of HCX network ports and protocols:
1. Management Port: TCP 443 (default) – Used for management traffic between the HCX Manager and the service appliances.
2. Data Port: TCP 80 (default) – Used for data traffic between the source and destination sites.
3. Control Plane Port: UDP 4172 (default) – Used for control plane traffic between the HCX peers at the source and destination sites.
4. Data Plane Port: UDP 4173 (default) – Used for data plane traffic between the source and destination sites.
Conclusion

In conclusion, deploying HCX in a production environment requires careful planning and preparation to ensure a successful deployment. By understanding the prerequisites and requirements for HCX, you can avoid potential issues and ensure that your deployment is smooth and efficient. As a seasoned System Engineer, I have learned that attention to detail and thorough planning are crucial for any IT project, and HCX deployments are no exception.
