The specific hardware required to run VMware Integrated OpenStack depends on the scale of your deployment and size of controller that you select.

The Integrated OpenStack Manager requires the following hardware resources:

  • 4 vCPUs
  • 16 GB of memory
  • One 60 GB hard disk and one 30 GB hard disk

A non-HA deployment requires between one and ten controllers. An HA deployment requires between three and ten controllers. The supported controller sizes are as follows:

  • Small: 4 vCPUs, 16 GB of memory, and one 25 GB hard disk
  • Medium: 8 vCPUs and 32 GB of memory, and one 50 GB hard disk
  • Large: 12 vCPUs and 32 GB of memory, and one 75 GB hard disk
Note: The small size can be used in HA deployments only. Non-HA deployments must use medium or large controllers.

The following persistent volumes are also required:

  • MariaDB: one 60 GB hard disk for non-HA deployments or three 60 GB hard disks for HA deployments
  • RabbitMQ: one 20 GB for non-HA deployments or three 20 GB hard disks for HA deployments
  • Virtual Serial Port Concentrator (VSPC): one 2 GB hard disk per Nova compute instance

The following table lists minimum and maximum resource requirements for typical configurations.

Note: If you want to enable Ceilometer, the CPUs on the ESXi host running the Integrated OpenStack Manager must support Advanced Vector Extensions (AVX).
Note: The ESXi hosts in one compute cluster should be configured with same CPU, memory, network adapters, GPU adapters, etc.

If you want to deploy VMware Integrated OpenStack with NSX-T Data Center or NSX Data Center for vSphere networking, additional resources may be required.
