Software Requirements for VDS Deployments

Before you begin the VMware Integrated OpenStack deployment tasks, the software components must meet all of the version prerequisites for vSphere, ESXi hosts. In a typical deployment, you require at least three ESXi hosts for the OpenStack management cluster and at least one ESXi host for the OpenStack compute cluster.

Requirement	Description
vSphere version	Supported versions: vSphere 6 Update 1 Enterprise Plus vSphere 6 Enterprise Plus vSphere 5.5 Update 3 Enterprise Plus vSphere 5.5 Update 2 Enterprise Plus
ESXi hosts	Supported versions: Version 6.0 Update 1 Version 6.0 Version 5.5 Update 3 Version 5.5 Update 2 Eight or more logical processors on each host. The vCenter and all ESXi hosts intended for the VMware Integrated OpenStack deployment must use the same Network Time Protocol (NTP) server. For details about configuring NTP on ESX servers, see the VMware knowledge base article at http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1003063.
