VXA Series Media Flow Engine andMedia Flow Solution Overview

Juniper Networks Media Flow Solution is a content delivery, distribution, and caching

solution that is purpose-built to address service providers’ needs for a new media network.

Media Flow Solution combines content intelligence with scalable, carrier-class Juniper

Networks hardware appliances to enable multiscreen delivery over a single, converged

content delivery infrastructure. Media Flow Solution enables service providers to monetize

rich media content, drive down transit costs, and improve the efficiency of content delivery.

Media Flow Solution combines advanced software and hardware that is specifically

designed to address the service provider’s new media delivery challenges. Purpose-built

for service provider deployments, Media Flow Solution provides a converged content

storage, distribution, and delivery solution that offers superior scale and dynamic

hierarchical caching capabilities. The solution is applicable to wireline and wireless service

providers and cable operators, and can be deployed to dramatically improve the efficiency,

scale, and performance of media delivery networks.

Media Flow Solution includes the following components:

• Media Flow Controller—A Junos®

Ready software application that combines deep,

media-aware intelligence (which identifies content and tracks and analyzes its

popularity) with awareness of the network, storage, and caching systems. Within a

single cache device, Media Flow Controller places objects into storage based on type,

size, and popularity, and dynamically manages content based on demand. Media Flow

Controller can be deployed in a hierarchy to efficiently distribute content across different

regions and geographies. Content that is requested frequently (hot content) can be

cached closer to the subscriber where it can be served rapidly, while content that is

rarely requested (long-tail content) can be kept more cost-effectively deeper in the

network. This capability enables service providers to rapidly and automatically adapt

to the unpredictable and ever-changing challenges of Internet content demand, while

concurrently optimizing the use of network resources.

• Media Flow Activate—A Junos Space software application that provides efficient,

centralized management of multiple Media Flow Controllers that can be deployed

throughout the service provider network. Media Flow Activate monitors system

resources and proactively maintains a record of key performance metrics. Media Flow


Activate also enables remote management and provisioning of the entire caching

infrastructure even in the most geographically distributed deployments. Interoperability

with existing operations support systems (OSSs) and base station subsystems (BSSs)

is provided by standard interfaces.

• VXA Series Media Flow Engines—A portfolio of purpose-built hardware appliances

that optimize the performance of the Media Flow Controller software and offer flexible

storage options. These appliances are powered by dual core or quad core Intel

processors and are available in four configurations that include models with Network

Equipment Building System (NEBS)-compliant form factors. Media Flow Engine

appliances offer expandable content storage options and can be flexibly configured

with up to 8 TB of cache that leverages a variety of RAM, solid-state drive (SSD), Serial

Advanced Technology Attachment (SATA), and Serial Attached SCSI (SAS)

technologies.

VXA Series Media Flow Engines include the following appliances:

• VXA1002 (model number VXA1002-JMF)—A 1-U appliance with a quad core CPU,

8 GB RAM, an AC power supply, and four pluggable drives.

• VXA2002 (model number VXA2002-JMF)—A 2-U Network Equipment-Building

System (NEBS) Level 3-compliant system with a quad core CPU, 36 GB RAM, dual

redundant hot-swappable DC power supplies, and 16 pluggable drives. Dual

redundant AC power supplies are an available option.

• VXA2010 (model number VXA2010-JMF)—A 2-U NEBS Level 3-compliant system

with a quad core CPU, 36 GB RAM, dual redundant hot-swappable DC power supplies,

and 16 pluggable drives. Dual redundant AC power supplies are an available option.

EnvironmentalRequirementsandSpecifications forVXA2USeriesMediaFlowEngines

The appliance must be installed in a rack housed in a dry, clean, well-ventilated, and

temperature-controlled environment.

Ensure that these environmental guidelines are followed:

• The site must be as dust-free as possible, because dust can clog air intake vents and

filters, reducing the efficiency of the appliance cooling system.

• Maintain ambient airflow for normal appliance operation. If the airflow is blocked or

restricted, or if the intake air is too warm, the appliance might overheat, causing the

appliance temperature monitor to power off the appliance to protect the hardware

components.

NOTE: InstallVXA2USeriesMediaFlowEnginesonly in restrictedareas, suchas dedicated equipment rooms and equipment closets, in accordance withArticles 110–16, 110–17, and 110–18of theNationalElectricalCode,ANSI/NFPA70.

Rack Requirements for VXA2U Series Media Flow Engines

Before you install a VXA2U Series Media Flow Engine in a rack, you must ensure that the

rack complies with a standard 19-in (48.26 cm) rack as defined inCabinets, Racks, Panels,

and Associated Equipment (document number EIA-310-D) published by the Electronics

Industry Association (http://www.eia.org). Refer to this standard for details on rack size

and mounting hole spacing.

When selecting a rack, ensure that the physical characteristics of the rack comply with

the following specifications:

• The size, strength, and location of the rack must accommodate the appliance's weight

and external dimensions.

• The inner edge of the rack rails must allow sufficient space for the width of the chassis.

• The rack must have sufficient vertical usable space to accommodate the height of the

appliance: 3.5 in (88.9 mm), or 2 U.

NOTE: AU is the standard rack unit defined inCabinets, Racks, Panels, andAssociated Equipment (document number EIA-310-D) published by theElectronics Industry Association.

• The rack must provide holes or hole patterns spaced at 1 U increments that match the

holes provided in the appliance mounting brackets.

• If you do not ground the appliance directly to a site earth-grounding facility, the rack

must be grounded to a reliable earth ground.

• You must use only copper grounding conductors.



http://www.eia.org

• To ensure a reliable, low-resistance ground bond between the chassis and the rack,

the mounting area on the rack should be paint-free, bare plated metal. The use of

thread-forming screws and placing external-tooth, paint-piercing lock washers between

the screw head and equipment mounting brackets help ensure a good ground bond.

You must provide these fasteners.

• The location of the rack must allow for the clearance requirements specified in

“Clearance Requirements for Airflow and Hardware Maintenance for VXA2U Series

Media Flow Engines” on page 17.

CAUTION: Always secure the rack in which you are installing theMedia FlowEngine to the structure of the building. If your geographical area is subject toearthquakes, bolt the rack to the floor. For maximum stability, also securethe rack to ceiling brackets.


General Safety Guidelines and Warnings for VXA Series Media Flow Engines on page 36•


• Clearance Requirements for Airflow and Hardware Maintenance for VXA2U Series


Clearance Requirements for Airflow and HardwareMaintenance for VXA2U SeriesMedia Flow Engines

When planning the installation site, allow sufficient clearance around the rack.

• For the cooling system to function properly, the airflow around the chassis must be

unrestricted.

• Allow at least 6 in. (15.2 cm) of clearance on the side between devices that have

fans or blowers installed.

• Allow 2.8 in. (7 cm) between the side of the chassis and any non-heat-producing

surface such as a wall.

• Ensure that the airflow vents in the front and rear panels remain open and uncovered

for proper cooling.

• For service personnel to remove and install hardware components, there must be

adequate space at the front and back of the appliance. NEBS GR-63 recommends

that you allow at least 30 in. (72.6 cm) in front of and behind the chassis.

Additional Hardware Requirements for VXA Series Media Flow Engines

Before installing the Media Flow Engine, ensure that you have access to the following

additional hardware devices:

• Serial console server or terminal server to assign an IP address after first powering on

the appliance.

• Uninterruptible power supply (UPS) for all appliances or systems running Media Flow

Solution software-storing data (such as consoles, event processors, or flow processors)

to preserve your data during a power failure.

We recommend that you install the Media Flow Engine on your LAN to ensure that it can

communicate with your applicable resources, such as authentication servers, DNS servers,

internal Web servers through HTTP/HTTPS, external Web sites through HTTP/HTTPS

(optional), the Juniper Networks update server by HTTP, Network File System (NFS) file

servers (optional), and client/server applications (optional). Table 11 on page 19 lists

DC Power Electrical Safety Guidelines for VXA2U Series Media Flow Engines

The following electrical safety guidelines apply to a DC-powered appliance:


Chapter 10: Electrical Safety Guidelines and Warnings

• A DC-powered appliance is equipped with a DC terminal block that is rated for the

power requirements of a maximally configured appliance.

NOTE: Tosupplysufficientpower, terminate theDC inputwiringona facilityDC source capable of supplying at least 8 A at –48 VDC.

Incorporate an easily accessible disconnect device into the facility wiring. Be sure to

connect the ground wire or conduit to a solid office earth ground. We recommend a

closed loop ring for terminating the ground conductor at the ground stud.


• Run two wires from the circuit breaker box to a source of 48 VDC.

• You must provide an external certified circuit breaker rated minimum 20 A in the building

installation.

• A DC-powered appliance that is equipped with a DC terminal block is intended only

for installation in a restricted access location. In the United States, a restricted access

area is one in accordance with Articles 110-16, 110-17, and 110-18 of the National Electrical

Code ANSI/NFPA 70.

CAUTION: Primaryovercurrentprotection isprovidedby thebuildingcircuitbreaker. This breaker must protect against excess currents, short circuits,and earth grounding faults in accordance with NEC ANSI/NFPA 70.

• Ensure that the polarity of the DC input wiring is correct. Under certain conditions,

connections with reversed polarity might trip the primary circuit breaker or damage

the equipment.

• For personal safety, connect a wire for earth ground at both the appliance and the

supply side of the DC wiring.

• The marked input voltage of –48 VDC for a DC-powered appliance is the nominal

voltage associated with the battery circuit, and any higher voltages are only to be

associated with float voltages for the charging function.

• Because the appliance is a positive ground system, you must connect the positive lead

to the terminal labeled RTN, the negative lead to the terminal labeled –48 VDC, and

the earth ground to the chassis grounding points.

• In addition to connecting a wire for earth ground to the chassis grounding studs, you

must also connect a wire for earth ground to the ground terminal provided on each DC

power supply.

Prevention of Electrostatic Discharge Damage on VXA Series Media Flow Engines

Media Flow Engine components that are shipped in antistatic bags are sensitive to damage

from static electricity. Some components can be impaired by voltages as low as 30 V.

You can easily generate potentially damaging static voltages whenever you handle plastic

or foam packing material or if you move components across plastic or carpets. Observe

the following guidelines to minimize the potential for electrostatic discharge (ESD)

damage, which can cause intermittent or complete component failures:

• Always use an ESD grounding strap when you are handling components that are subject

to ESD damage, and make sure that it is in direct contact with your skin.

If a grounding strap is not available, hold the component in its antistatic bag in one

hand, and touch the exposed, bare metal of the appliance with the other hand

immediately before inserting the component into the appliance.

CAUTION: For safety, periodically check the resistance value of the ESDstrap. Themeasurementmust be in the range of 1 through 10Mohms.

• Avoid contact between the component that is subject to ESD damage and your clothing.

ESD voltages emitted from clothing can damage components.

• When removing or installing a component that is subject to ESD damage, always place

it component-side up on an antistatic surface, in an antistatic card rack, or in an

antistatic bag. If you are returning a component, place it in an antistatic bag before

packing it.

CAUTION: ANSI/TIA/EIA-568 cables such as category 5e and category 6can get electrostatically charged. To dissipate this charge, always groundthe cables to a suitable and safe earth groundbefore connecting them to thesystem.

Returning VXA Series Products for Repair or Replacement on page 83•

Before You Install VXA2U Series Media Flow Engines

Before installing a VXA Series Media Flow Engine:

• Verify that the site meets all environment specifications. See “Environmental

Requirements and Specifications for VXA2U Series Media Flow Engines” on page 15.

• Read and understand the clearance requirements for the appliance to ensure adequate

ventilation and enable access to the appliance for maintenance. See “Clearance

Requirements for Airflow and Hardware Maintenance for VXA2U Series Media Flow

Engines” on page 17.

• Have the tools and accessories needed to complete the installation. See “Unpacking

and Inspecting VXA Series Media Flow Engines” on page 47. In addition, you need a

wrench or nut driver sized to fit the nuts on the chassis earth ground lugs, and the

appropriate tools to fasten the ground wire to the rack frame, ground rail, or other site

grounding facility.

• Verify that the cables you plan to use meet the specifications, and review the cabling

recommendations. See “AC Power Cord Specifications for VXA Series Media Flow

Engines” on page 21 and “RJ-45 Console Connector Pinout for VXA Series Media Flow

Engines” on page 21. Have plastic cable ties or other means to secure traffic and power

cables safely out of the way.

• Verify that the electrical supply meets all DC or AC power requirements. See “Power

Specifications for VXA2U Series Media Flow Engines” on page 25.

When equipped with DC power supplies, the VXA2U Series Media Flow Engine supports

a DC isolated return (DC-I) installation. In a DC-I installation, the DC power return



conductor is isolated from the equipment chassis or frame when connected to the

power supply.

• Consider the following guidelines before installing the appliance:

• The nominal working voltage range for a DC-power-equipped appliance is -48 VDC.

This appliance can operate over an input voltage range from -38 VDC to -72 VDC.

• For DC-power-equipped appliances, you must provide an external certified, dedicated

circuit breaker rated at a minimum of 20 A for each DC power supply.

• For DC-power-equipped appliances, you must supply four DC power cables that

meet your local code requirements.

• For AC-power-equipped appliances you must provide an external surge protection

device (SPD).

• You must supply a cable to provide an earth ground for the chassis. On

DC-power-equipped models, you must supply a ground cable for each power supply.

We recommend using a ground cable identified according to local standards to

ground the appliance.

For example, a green wire is typical for ground conductors in the United States,

Canada, and countries that follow similar wiring codes for 60-Hz power supplies. A

green-and-yellow striped wire is typical for ground conductors in Europe and countries

that follow a similar wiring code for 50-Hz power supplies.

We recommend using the following ground lug: Panduit P/N LCDX8-10A-L, #8 AWG,

#10 stud, 0.625-inch spacing for the ground connection to the chassis grounding

studs.


• To ensure a reliable low-resistance ground bond, you must provide and use

thread-forming screws with paint-piercing lock washers to secure the ground wire

to the rack frame, and to secure the appliance chassis to the rack

If you connect the ground wire to a ground rail in the rack or to any other grounding

facility provided by the site, you must use the appropriate fasteners to ensure a

reliable ground bond. When the ground wire is attached with bolts or to studs, lock

washers can help ensure the ground wire does not come loose.

• Tighten all fasteners to the torque specification recommended by the manufacturer

of the fastener or recommended by a recognized standards organization for that

size of fastener. Do not overtighten the fasteners.

For example, the following values are typical torque specifications for rack screws:

• 10-32—20 in-lb

• 12-24—30 in-lb


Chapter 11: Preparing the Installation

• M6—20 in-lb

• You must coat bare conductors with an appropriate antioxidizing compound before

making any crimp connections. Bring all unplated connectors, braided strap, and

bus bars to a bright finish and then coat them with an appropriate antioxidizing

compound before you connect them.

Connecting Power to DC-Powered VXA2U Series Media Flow Engines

Figure 10 on page 57 shows the DC power connections on a VXA2U Series Media Flow

Engine.

WARNING: Before performing DC power procedures, ensure that power isremoved from theDC circuit. To ensure that all power is off, locate the circuitbreaker that services the DC circuit, switch the circuit breaker to the offposition, andsecure theswitchhandleof thecircuit breaker in theoffposition.

CAUTION: Donotmix ACandDCpower supplieswithin the sameappliance.Damage to the appliancemight occur.

NOTE: See “Grounding VXA2U Series Media Flow Engines” on page 53 fordetailed information on grounding requirements.

Ensure that the equipment rack is properly grounded and the appliance has a good

low-resistance ground bond to the rack before you connect power to the DC power

supplies.

Connect DC power to the appliance by attaching power cables from the external DC

power sources to the terminals on the power supply faceplates. You must provide the

power cables.


Chapter 13: Cabling

To connect the DC source power cables to a DC power supply on the appliance:

1. Switch off the dedicated customer site circuit breakers for the power supplies. Ensure

that the voltage across the DC power source cable leads is 0 V and that there is no

chance that the cable leads might become active during installation.

2. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect

the strap to the ESD point on the chassis.

3. Verify that the DC power cables are correctly labeled before making connections to

the power supply. In a typical power distribution scheme where the return is connected

to chassis ground at the battery plant, you can use a multimeter to verify the resistance

of the V- (–48V) and V+ (RTN) DC cables to chassis ground:

• The cable with very large resistance (indicating an open circuit) to chassis ground

is V- (–48V).

• The cable with very low resistance (indicating a closed circuit) to chassis ground is

V+ (RTN).

CAUTION: Youmust ensure that power connectionsmaintain the properpolarity. The power source cablesmight be labeled (+)and (–) to indicate

their polarity. There is no standard color coding for DC power cables. Thecolor coding usedby the externalDCpower source at your site determinesthe color coding for the leads on the power cables that attach to theterminals on each power supply.

4. Attach the power cables.

a. Remove the protective cover from the DC terminals on the power supplies.

b. Loosen the DC terminal screws.

c. Insert the positive (+) DC source power cable, and tighten the screw to secure the

cable to the V+ (RTN) return terminal.

d. Insert the negative (–) DC source power cable, and tighten the screw to secure the

cable to the V- (–48V) input terminal.
