Juniper SPACE VIRTUAL CONTROL Manual de usuario

DATASHEET

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 Junos Space, an open, extensible platform for developing and hosting

applications designed to reduce cost and complexity while opening networks to new

business opportunities, 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,

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.

Product 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 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).

JUNOS SPACE VIRTUAL CONTROL

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, 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.

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 vNetwork Distributed Switch

(vDS) framework. Using Virtual Control, users can discover,

manage and monitor the entire virtual network (vNetwork)

inventory consisting of vSphere Hosts, vDSs, and virtual machines

from multiple VMware vCenter Server instances.

Virtual Control efficiently manages vDS 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.

Virtual Control also allows users to group VMware’s recommended

vDS 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 vDSs.

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, 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

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.

Junos Space

One of the core members of the Juniper Networks Junos operating

system platform, Junos Space uses the same design principles and

open systems approach as Junos OS to enable programmability at

the network application layer.

Junos Space is a multipurpose application platform designed to

be simple, smart, and open.

• Smart—The core platform provides network abstractions and

automation to enable smart applications, and it includes best

practices to automate repetitive tasks, minimize user input, and

scale services.

• Simple—The platform interface is business intent-oriented, not

technology-centric, with the system guiding the user rather than

the other way around.

• Open—The platform architecture is open and explicitly designed

to enable partners to build and deploy applications that are

smart, simple, and easy to use.

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 vDS, and presents various views of the

inventory to the network operator.

Oers 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 o

ports to prevent “misbehaving” virtual machines from accessing the network.

Improves operational eciency.

Virtual switch port

proﬁles

Allows grouping of common networking attributes on virtual switch ports.

Virtual Control supports proﬁles for VMware vDS 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 dierent vDSs. 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.

Oers better network security and

eciency, 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. Virtual Control

also generates a detailed audit report and raises alarms whenever an

incorrect conﬁguration aects virtual machine trac.

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.

Non-disruptive

installation

Plugs into existing vSphere installations without disruption. Supports plug-and-play operation with

no service disruption.

Variable form factors Runs on the Junos Space platform, as a virtual appliance on a VMware server,

or on a dedicated Junos Space physical appliance.

Oers the ﬂexibility to adapt to the

organization’s management needs.

Web 2.0 graphical user

interface

Uses a Web 2.0 GUI and is designed to simplify the way network operators

interact with the system.

Supports intuitive, personalized

workﬂows, real-time network status, and

a statistical dashboard view to improve

operator productivity.
