VMware HCX on IBM Cloud overview
VMware HCX™ on IBM Cloud® extends the networks of on-premises data centers into IBM Cloud®, and it helps you migrate virtual machines (VMs) to and from IBM Cloud without any conversion or change. HCX creates an abstraction layer that enables application mobility and infrastructure hybridity through securely stretched networks. You can modernize your VMware® environment without the need to refactor or modify your existing application, as HCX enables a seamless transformation. With HCX, you can bring your IP subnet ranges into IBM Cloud and ensure the IP consistency through a hybrid deployment and by providing high-level security with end-to-end Suite B encryptions. VMware HCX on IBM Cloud is a non-IBM product that is offered under terms and conditions from VMware, not IBM.
The HCX version available for deployment is periodically updated to the most recent version of HCX. VMware® by Broadcom requires you to be on one of their supported versions in order for you to open a support request for HCX. For more information, see the VMware HCX release notes.
For VMware Cloud Foundation for Classic - Automated with NSX-T™ instances, HCX is supported for NSX-T 3.1 or later and for VMware vSphere® 7.
For VCF for Classic - Automated with NSX-V instances (VMware Solutions V4.7 and earlier), HCX is supported for vSphere 6.7.
IBM Cloud® for VMware Solutions offers promotions for some add-on services. Promotional pricing offers a number of months at no cost for a service license, if the service has license charges. For more information, see Promotions for services.
A VCF for Classic - Automated instance with HCX is limited to three simultaneous connections from on-premises sites.
