The hardware requirements are based on the number of VMs used for each component. For example, two VMs are used for load balancing, each of which requires two CPUs for a total requirement of four CPUs. The requirements vary depending on whether your OpenStack deployment uses Virtual Distributed Switch (VDS) or VMware NSX for vSphere (NSX) with the Networking component.

VMware Integrated OpenStack Requirements for Compact Mode
VMware Integrated OpenStack 3.0 supports a new deployment mode -- compact mode, which runs using a minimal amount of hardware. For information on the hardware requirements for running in compact mode, see the VMware Integrated OpenStack Installation and Configuration Guide.
NSX Components
Additional CPU, RAM, and disk space is required for NSX components if they are deployed with VMware Integrated OpenStack.
