This chapter contains the following sections.
Cisco Virtual Application Cloud Segmentation (VACS) Services is a software solution that automates the coordinated licensing, installation, and deployment of multiple virtual services in your datacenter to enable an easy and efficient setup of virtualized applications. Cisco VACS provides a fully customizable extended application container abstraction to simplify deploying and provisioning the virtual services. Cisco VACS allows you to define extended application container templates and to instantiate them through automated setup and provisioning of the underlying virtual components. Cisco UCS Director provides the management interface to deploy, provision, and monitor the Cisco VACS solution.
Cisco VACS provides you with a choice of ready-to-use application container templates that define the rules for deploying a collection of virtual machines (VMs) within a private network secured by a firewall. An application container is a set of virtual services such as virtual switches, routers, firewalls, and other network devices configured in a consistent manner to deploy different workloads. When you create and instantiate an application container template, Cisco VACS deploys VMs, and configures networks, the firewall, and virtual switches, and enables quick provisioning of network and security at the virtual layer.
The following figure shows how these components fit into the architecture of Cisco VACS.
A simplified and central provisioning solution for virtual network services.
Ready-to-use regulatory compliant secure containers that can be created and instantiated with a few mouse clicks.
Hypervisor-independent architecture that enables you to build and manage a secure, multi-tenant cloud.
Consistent deployment of virtual and physical resources with no additional costs.
For more information about how to configure the application container templates on Cisco VACS, see the Cisco Virtual Application Cloud Segmentation Services Configuration Guide.
Cisco VACS includes a set of wizards that guide you through the installation of Cisco PNSC and Cisco Nexus 1000V, and adding hosts and templates. Following are the available wizards:
Install PNSC
This wizard helps you to install the Cisco Prime Network Services Controller (PNSC).
Install Nexus 1000V
This wizard helps you to install the Cisco Nexus 1000V virtual switch.
Add Host
This wizard helps you to add hosts to the Cisco Nexus 1000V DVS.
Options
This wizard allows you to hide or display the application container configurations that can be edited by the end users.
Add ASAv License
This wizard allows you to install the Cisco ASAv license.
Add Template
This wizard allows you to create a container template.
After you install the Cisco UCS Director – Cisco VACS license and apply the Cisco VACS patch to the Cisco UCS Director, you can view the Cisco VACS solution under the tab.

Service End User—Enables you to instantiate a Cisco VACS container from the catalog and services that are related to the container.
System Administrator—Enables you to have full privileges to manage Cisco VACS in Cisco UCS Director including adding accounts, defining policies, creating application templates, instantiating application containers from the templates, and troubleshoot problems.
Depending on your user role, your view of Cisco VACS solution, and the permissions to access and perform tasks in Cisco UCS Director might differ. For detailed information about user roles and privileges, see the Cisco UCS Director Administration Guide and the Cisco UCS Director Self-Service Portal Guide.
Cisco UCS Director is a 64-bit appliance that uses the Open Virtualization Format (OVF) for VMware vSphere standard template:
Cisco UCS Director delivers unified, highly secure management for converged infrastructure solutions, that are based on the Cisco UCS and Cisco Nexus platforms.
Cisco UCS Director extends the unification of computing and network layers through Cisco UCS to provide you with a comprehensive visibility and management capability. It supports NetApp FlexPod and ExpressPod, EMC Isilon, EMC VSPEX, EMC VPLEX, and VCE Vblock systems, which are based on the Cisco UCS and Cisco Nexus platforms.
Cisco UCS Director automates the provisioning of resource pools across physical, virtual, and baremetal environments. It delivers native, automated monitoring for health, status, and resource utilization. You can do the following using Cisco UCS Director:
Create, clone, and deploy service profiles and templates for all servers and applications
Monitor organizational usage, trends, and capacity across a converged infrastructure on a continuous basis, such as by viewing heat maps that show virtual machine (VM) utilization across all your data centers
Deploy and add capacity to ExpressPod and FlexPod infrastructures in a consistent, repeatable manner
Manage, monitor, and report on Cisco UCS domains and their components
Extend virtual service catalogs to include physical infrastructures services
Manage secure multitenant environments to accommodate virtualized workloads that run with nonvirtualized workloads
The Virtual Supervisor Module (VSM) is the control plane of the Cisco Nexus 1000V. It is deployed as a virtual machine.
Cisco VACS supports the installation of the VSM in a high-availability (HA) pair using the automated Cisco VACS installation.
The VSM, along with the VEMs that it controls, performs the following functions for the Cisco Nexus 1000V system:
The VSM uses an external network fabric to communicate with the VEMs. The VSM runs the control plane protocols and configures the state of each VEM, but it never forwards packets. The physical NICs on the VEM server are the uplinks to the external fabric. VEMs switch traffic between the local virtual Ethernet ports that are connected to the VM vNICs but do not switch traffic to other VEMs. Instead, a source VEM switches packets to the uplinks that the external fabric delivers to the target VEM.
A single Cisco Nexus 1000V instance, including dual-redundant VSMs and managed VEMs, forms a switch domain. Each Cisco Nexus 1000V domain within a VMware vCenter Server must be distinguished by a unique integer called the domain identifier.
A single VSM can control up to 250 VEMs.
While using the VSG, it can control up to 128 VEMS.
See the Cisco Nexus 1000V Resource Availability Reference for information about scale limits.
The Cisco Nexus 1000V architecture is shown in the following figure.
