Proiduct Overview The proliferation of virtual switches in the data center has presented data center operators with a significant challenge—namely, how to manage these virtual network elements in conjunction with the physical network. The tools that network operators currently use to manage their physical infrastructure provide no access to, or visibility into, the virtual infrastructure.
Junos Space Virtual Control unifies physical and virtual infrastructures, providing network operators with a comprehensive view into the complete end- to-end network. Using Junos Space Virtual Control, network operators can manage, monitor and control both virtual and physical networks through a single pane of glass, ensuring that network policies are consistently and automatically applied across the infrastructure. This enables error free network operations and simplifies the deployment of value-added services such as virtual machine live migration (e.g., VMware VMotion).
Product Description
Juniper Networks® Junos® Space Virtual Control allows users to manage, monitor, and control the virtual networks that run within virtualized servers deployed in the data center.
Built on the Junos Space Network Management Platform, a software platform providing comprehensive FCAPS and element management of Juniper devices to help improve operator efficiencies, Junos Space Virtual Control contributes to a comprehensive solution that extends across the routing, switching, and security infrastructure.
Rather than rebuild the virtual switch that comes as part of the hypervisor software, Junos Space Virtual Control integrates with the hypervisor vendor’s existing management tools, delivering a combined solution that benefits from both vendors’ innovation and Juniper Networks’ orchestration solutions.
The Challenge of Server Virtualization
Server virtualization allows IT organizations to collapse multiple physical servers onto virtual machines running on a single host using software called a hypervisor. The hypervisor provides the physical resource abstraction to virtual machines deployed on the host, while virtual switches provide connectivity between virtual machines residing on the same host.
These virtual switches blur the lines of responsibility between traditional network, security, and server teams. Virtual switches require a different set of management tools than physical switches, making it difficult for network operators to obtain a consolidated and consistent view of the entire network. Since the physical network must be in sync with the virtual network to provide the connectivity services required by applications in a virtual environment, this lack of visibility hampers the network operator’s ability to ensure smooth operations in virtualized data centers, especially when dynamic events such as virtual machine live migration are taking place.
Junos Space Virtual Control
Your ideas. Connected.™
Junos Space Virtual Control addresses these problems by providing network operators with an open, scalable and unified policy-based solution for managing both virtual and physical networks. By implementing a collaborative management
paradigm, Junos Space Virtual Control enables flexible operational deployment models and management handoffs between network and server teams, depending on the policies and needs of the organization, to ensure maximum business agility.
Junos Space Virtual Control’s Virtual-to-Physical Mapper and P+V Dynamic Orchestrator features also fully automate physical infrastructure provisioning, helping to eliminate configuration conflicts between virtual and physical networks and increasing the efficiency of day-to-day network operations.

Integration with VMware
Junos Space Virtual Control integrates with VMware vSphere, providing access to the VMware virtual switch (vSwitch) framework (both vNetwork Distributed Switch and vNetwork Standard Switch). Using Junos Space Virtual Control, users can discover, manage and monitor the entire virtual network (vNetwork) inventory consisting of vSphere Hosts, vSwitches, and virtual machines from multiple VMware vCenter Server instances.
Junos Space Virtual Control efficiently manages vSwitch Port Groups and Uplink Port Groups and constantly monitors, logs, and reacts to vNetwork events to keep track of virtual machine locations in the network. Junos Space Virtual Control also allows users to group VMware’s recommended vSwitch Port Group best practice settings into profiles; using these profiles, Port Groups that share best practice settings but have varying VLAN requirements can be quickly and easily deployed on different vSwitches.
Junos Space Virtual Control can also be used to discover Port Groups being managed via VMware vCenter Server. This allows for flexible operational models that define how management responsibilities are split between network and server teams. In addition, Junos Space Virtual Control enables error free deployment of VMware services such as VMotion, Distributed Resource Scheduler (DRS), high availability (HA), and fault tolerance.

Web-Based Interface
Junos Space Virtual Control uses a Web 2.0 interface to manage both virtual and physical networks consisting of Juniper devices such as switches, routers, and security platforms. The application provides a task-oriented GUI which enables users to complete tasks in congruent navigation steps and screen flows without context switches.

Features and Benefits
Feature Description Benefits
Collaborative management
Junos Space Virtual Control supports the following operational models:
1) vNetwork Access Control: Enables the network operator to provision, define, and deploy end-to-end policies on virtual and physical networks.
Server administrators retain control over virtual machine management and associating virtual machines with the policies defined by the network operator.
2) vNetwork Monitor: Gives network operators visibility into the virtual network, but not necessarily “write” access.
3) vNetwork Cloud: Delivers powerful P+V Dynamic Orchestrator and vNetwork event monitoring capabilities in cloud deployments where virtual network infrastructure provisioning is fully automated by cloud management tools such as VMware vCloud Director.
Provides the flexibility to adopt an operational model that best fits the organization.
vNetwork inventory management
Discovers and constantly updates the complete virtual network inventory, including vSphere Hosts, virtual switches, and virtual machines, as well as existing Port Group definitions on the vSwitch, and presents various views of the inventory to the network operator.
Offers complete visibility into the current state of the vNetwork.
Virtual-to-Physical Mapper
Provides information on connectivity between virtual and physical networks and the association of virtual switch uplink ports to external physical switch ports.
Provides end-to-end network view and simplifies troubleshooting.
VM Locator Ensures that the network operator always knows the current location of each virtual machine on the vNetwork. The network operator can also shut off ports to prevent “misbehaving” virtual machines from accessing the network.
Improves operational efficiency.
Virtual switch port profiles
Allows grouping of common networking attributes on virtual switch ports.
Virtual Control supports profiles for VMware vSwitch Port Groups, enabling the rapid deployment of Port Groups that share VMware best practices network settings (QoS, security, network interface card teaming, failover; etc.) but have conflicting VLAN requirements on different vSwitches. Profiles can be cloned, and Port Groups that share a profile can be easily viewed.
P+V Dynamic Orchestrator
• P+V Dynamic Orchestrator constantly monitors vNetwork changes and automatically provisions the physical network infrastructure to adjust for those changes.
• Orchestration supports “strict” and “very strict” modes. Strict mode automates the setup of specific network policies (i.e. VLAN) on physical switch ports spanning a server cluster based on the corresponding configuration enabled on the vNetwork. This is the “connectivity for cluster”
model.
• Very strict mode automates the setup of specific network policies (i.e.
VLAN) on physical switch ports spanning a server cluster based on
“active” policies being used by virtual machines in the vNetwork. Policies may be dynamically reconfigured when a virtual machine changes locations. This is the “connectivity on demand” model.
• Automates physical network setup and reduces downtime due to configuration conflicts.
• Enables error free and scalable deployment of services such as VMware VMotion, Distributed Resource Scheduler (DRS), high availability, and fault tolerance.
• Offers better network security and efficiency, especially in multi- tenant deployments.
Configuration audit Virtualized data centers are dynamic environments with frequent changes.
With Virtual Control, network operators can issue configuration audit checks for the vNetwork as well as the connected physical network. Junos Space Virtual Control also generates a detailed audit report and raises alarms whenever an incorrect configuration affects virtual machine traffic.
Allows network operators to be quickly informed of and react to configuration faults that could cause outages.
Multiple vCenter server instances
Discovers and maintains inventory from multiple vCenter server instances to provide a consolidated network view.
Consolidates management in multi- tenancy cases.
Event and audit logs Maintains a log of all vNetwork events and automatically records all actions performed by users in the GUI. Network operators can check and generate reports on user activity.
Provides historical record of vNetwork events and user activities.
