Data Center Interconnect

Connecting data centers with compact, power-efficient, high-speed transport

Macro Trends Driving Traffic Growth

As growing numbers of consumers routinely

turn to cloud-based entertainment and Over-

the-Top (OTT) services such as streaming

music and movies, more and more traffic is

passing through and between data centers.

Three macro trends are driving rapid escalation

in data center bandwidth demand:

■ Evolution to cloud services – Moving

services to the cloud reduces individual

capital expenditures and shifts these

demands to a centralized data center.

■ Explosion of video and OTT traffic – To

reduce total bandwidth costs, when

possible, video and OTT content is cached

locally in data centers, driving increased

need for metro content delivery networks.

■Specialized applications that require

connected data centers – Some

applications, such as digital media delivery,

cloud computing, business continuity

and disaster recovery, require multiple

interconnected data centers.

Factors Constraining Bandwidth

Growth

This growing demand for cloud-based content

delivery is putting pressure on the connections

among and between data centers, known as

DCI. The result is congestion and bottlenecks

that have a ripple effect on the speed of

content delivery.

There is now an urgent need to boost the

capacity and speed of the transport networks

that relay information between data centers

and to/from Internet Exchange Points (IXPs).

At the same time, there is heavy downward

pressure on cost, power consumption, and the

amount of physical space occupied by data

center equipment in general.

Cost Burdens of Co-location Leasing

Lease charges for co-location facilities are

based on the amount of rack space and power

consumed. Because these charges are such a

significant portion of the overall cost of a data

center, it is imperative to reduce the monthly

cost of space and power in order to reduce

Total Cost of Ownership (TCO).

Complex Chassis-Based Systems

Typical data center interconnections use

complex chassis-based systems. These

integrated platforms are populated with

interface cards in a wide variety of

configurations that serve multiple functions,

such as switching, transponding and DWDM

multiplexing. Physical size, wasted space, high

power consumption, lack of flexibility,

insufficient room for growth, and complicated

management procedures are all disadvantages

of this type of hardware architecture.

DCI Traffic Characteristics

■ DCI traffic predominantly flows across point-

to-point connections.

■ Bandwidth demands are typically met with

DWDM multiplexers rather than ROADMs.

■ When leasing space in a co-location facility,

it is sometimes more economical to lease

a few wavelengths rather than owning and

managing DWDM transport systems.

■ Most data center traffic is transported

over 10G and 100G wavelengths, but

increased demand for bandwidth will result

in higher rates.

Application Benefits

Fujitsu Data Center Interconnect (DCI)

applications help solve space and power

challenges while reducing costs:

■ Compact physical footprint

■ Low power consumption

■ Scalability to 200G per wavelength

■ Open, modular architecture

Application Note Data Center Interconnect

Modular, Scalable, Flexible, Operationally Simple

Small Form-Factor Blade-Based Hardware Architecture

Constraints on rack space are the chief reason why it is no longer optimal

to consolidate multiple functions onto a single chassis. A new approach

is to separate functional capabilities into standalone 1RU devices, known

as “blades.”

Advantages of this blade-based, modular hardware architecture include:

■ Shorter, more precisely targeted development and release cycles

■ Lower cost of entry

■ Scalable pay-as-you-grow implementation path

■ Faster and simpler deployment and provisioning

■ Efficient use of resources such as space and power

1FINITY Optical Networking Platforms for DCI

The Fujitsu 1FINITY platform family is a modular “blade-based”

architecture rather than a converged “chassis-based” architecture.

Various 1FINITY platforms can serve different functions in a DCI

application. The following platforms are described in this

application note:

■ 1FINITY T100

• Transponds 100 GbE signals on a 200G wavelength using 16-QAM

• Transponds 100 GbE signals on a 100G wavelength using DP-QPSK

■ 1FINITY T200

• Transponds 100 GbE signals on a 200G wavelength using 16-QAM

• Transponds 100 GbE signals on a 100G wavelength using DP-QPSK

• Transponds 100 GbE signals on a 150G wavelength using 8-QAM

■ 1FINITY T210

• Transponds 100 GbE signals on a 100G wavelength using DP-QPSK

with ultra long-reach

■ 1FINITY T400

• Performs Layer 1 aggregation of 10 GbE into 100G

■ 1FINITY S100

• Provides full-featured E-Line services for 10 to 100 GbE aggregation

■ 1FINITY L100

• Performs DWDM ROADM functions

Application Types

Fujitsu offers five DCI applications. The first four can be deployed for

either metro DCI (mDCI) or long-reach uses, and the fifth, submarine

DCI, is an inherently long-reach application. The applications are:

■ Basic DCI – Metro and long reach

■ Access peering

■ Remote router access

■ Dual-peering with a shared router

■ Submarine DCI (long-reach only)

Basic DCI

With the unprecedented growth in OTT and cloud applications, this

application easily meets growing need for bandwidth at the

interconnection points between data centers. Point-to-point

connections can be set up in a variety of configurations.

Metro DCI

The metro DCI application combines the 1FINITY T100 with other

1FINITY platforms for the following functions:

■ 1FINITY T100 provides 100 GbE services across 100G or 200G

wavelengths using DP-QPSK or DP-16QAM modulation for reach

up to 3,200 km

■ 1FINITY T400 can aggregate 10 GbE to 100G at Layer 1

■ 1FINITY S100 can aggregate 10 GbE to 100G at Layer 2

■ 1FINITY L100 or FLASHWAVE 7120 can provide DWDM mux/demux

Long-Reach DCI

Long-reach DCI applications are available using the 1FINITY T200 in

place of the T100, with the same 1FINITY platforms as in metro DCI, as

listed above.

■ 1FINITY T200 provides 100 GbE services across 100G, 150G or 200G

wavelengths using DP-QPSK, DP-8QAM or DP-16QAM modulation for

extended reach up to 6,000 km

Applications for a Variety of DCI Needs

Access Peering

This application is ideal where a high bandwidth connection is needed

between a data center and a peering point. A variety of 1FINITY point-

to-point configurations can be set up over time to support increasing

demand. Examples include using the 1FINITY L100 for ROADM, mux/

demux or even direct connection; Layer 1 or 2 aggregation; long/short

reach scenarios; and amplified or unamplified configurations.

Additonal options for this application include:

■ Adding the T400 or S100 for 10 GbE demands

■ Substituting the T200 for the T100 in long-reach scenarios

Access Peering Application

Remote Router Access

This application addresses the problem of high demand and limited

rack space, especially where a router and a switch are desired at the IXP.

A variety of 1FINITY point-to-point configurations can be set up to divert

traffic to a router and switch located at a private data center instead.

This reduces the space needed at the expensive IXP while maintaining

a peering presence at that IXP.

Additional options for this application include:

■ Adding the 1FINITY T400 or S100 for 10 GbE demands

■ Substituting the T200 for the T100 in long-reach scenarios

Suitable for High-Resiliency and Long-Reach Deployment

Dual Peering with Shared Router

When increased resiliency is provided using dual access at two nearby

IXPs, the cost and space demands of maintaining a large switch and

router at both IXPs can be high. A variety of 1FINITY point-to-point

configurations can be set up to divert the traffic to a router and switch

located at one of the peering points. This reduces the space

requirements at one IXP and reduces the overall number of expensive

routers and switches, while maintaining dual peering.

Additional options for this application include:

■ Adding the 1FINITY T400 or S100 for 10 GbE demands

■ Use the 1FINITY T200 instead of the T100 for long-reach scenarios

Submarine DCI

The growth in DCI traffic also extends to intercontinental data center

connections. Intercontinental routes almost always traverse deep ocean

and long distances. The 1FINITY T210 can be used in sub-sea

applications, with the 1FINITY T400 or 1FINITY S100 added for 10 GbE

services. Typically these sub-sea applications use an existing DWDM

muxponder and long-reach transponders.

Services Expertise to Support Successful Implementation

Successful implementation depends on the right expertise. A team of

optical network integration experts can provide this crucial expertise

during the design and planning phases, as well as during deployment.

Optical networking experts help you anticipate or avoid obstacles,

control costs, minimize delays and maintain high quality standards.

Most ICPs have plenty of IT talent, but a lack of qualified optical

networking staff can be a deterrent to the move to an owned network.

The economic benefits of moving from leased services to managing

your own optical equipment are impossible to ignore once traffic

volume and the number of wavelengths reaches a certain point.

Delaying the move to owned optical equipment only increases your

service cost. Fujitsu offers optical integration services that close this skill

gap and enable you to reap the benefits of an improved cost structure

and greater control of your business.

Fujitsu offers the following services to support your successful DCI

implementation:

■ Optical network design and planning

■ Optical fiber characterization and testing

■ Supply chain, logistics, inventory and project management

■ Installation and deployment

■ Optical network maintenance and support

Increase Density, Reduce Power Demand, Control Costs

By choosing a Fujitsu 1FINITY DCI solution to provide connections

between data centers or between a data center and an IXP, you can

achieve significant long-term economic benefits. 1FINITY DCI solutions

break through traffic bottlenecks while dramatically increasing density

and reducing power usage at the optical, transponder and Ethernet

layers. By deploying a DCI solution based on 1FINITY, you can reduce

capex and opex, cut time to market for new services, and ultimately

merge your data centers into a single managed network.
