Software Requirements for NSX Deployments

Before you begin the VMware Integrated OpenStack deployment tasks, the software components must meet all of the version prerequisites for vSphere, ESXi hosts, and the NSX product. 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: See the VMware Product Interoperability Matrix at http://partnerweb.vmware.com/comp_guide2/sim/interop_matrix.php for the supported versions.
ESXi hosts	Supported versions: See the VMware Product Interoperability Matrix at http://partnerweb.vmware.com/comp_guide2/sim/interop_matrix.php for the supported versions. Eight or more logical processors on each host. The vCenter Server 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/kb/1003063 and the vSphere documentation at Edit Time Configuration for a Host.
NSX	NSX Advanced or Enterprise license. See the VMware Product Interoperability Matrix at http://partnerweb.vmware.com/comp_guide2/sim/interop_matrix.php for the preferred version.
