Application Note 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 Overthe-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 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 Functional Elements Fujitsu DCI applications comprise three main elements, which can be mixed and matched to provide a variety of configurations: ■■1FINITY™ optical networking platforms ■■ Virtuora® SDN/NFV software suite ■■ Fujitsu optical services Page 1 of 5 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. us.fujitsu.com/telecom Application Note Data Center Interconnect Modular, Scalable, Flexible, Operationally Simple Small Form-Factor Blade-Based Hardware Architecture Basic DCI 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.” 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. 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 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 ■■ 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 Virtuora Virtuora Virtuora NM Design NC Network Management DCN ■■ 1FINITY T210 • Transponds 100 GbE signals on a 100G wavelength using DP-QPSK with ultra long-reach Data Center ■■ 1FINITY T400 Data Center Long Reach DCI • Performs Layer 1 aggregation of 10 GbE into 100G ■■ 1FINITY S100 • Provides full-featured E-Line services for 10 to 100 GbE aggregation mDCI ■■ 1FINITY L100 Fujitsu Optical Services • 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 Data Center Data Center Basic DCI Application with Long Reach (Top Right) ■■ Remote router access ■■ Dual-peering with a shared router ■■ Submarine DCI (long-reach only) Page 2 of 5 us.fujitsu.com/telecom Application Note Data Center Interconnect Applications for a Variety of DCI Needs Access Peering Remote Router Access This application is ideal where a high bandwidth connection is needed between a data center and a peering point. A variety of 1FINITY pointto-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. 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. Additonal options for this application include: Additional options for this application include: ■■ Adding the T400 or S100 for 10 GbE demands ■■ Adding the 1FINITY T400 or S100 for 10 GbE demands ■■ Substituting the T200 for the T100 in long-reach scenarios ■■ Substituting the T200 for the T100 in long-reach scenarios Virtuora Virtuora Virtuora NM Design NC Internet Network Management DCN IXP Virtuora Virtuora Virtuora NM Design NC Network Management DCN Internet Data Center IXP Fujitsu Optical Services Fujitsu Optical Services Access Peering Application Data Center Remote Router Access Application Page 3 of 5 us.fujitsu.com/telecom Application Note Data Center Interconnect Suitable for High-Resiliency and Long-Reach Deployment Dual Peering with Shared Router Submarine DCI 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. 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. 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 Virtuora Virtuora Virtuora NM Design NC Network Management DCN Virtuora Virtuora Virtuora NM Design NC Cable Termination Station Internet Network Management DCN Cable Landing Station Wet Plant IXP Cable Landing Station IXP Fujitsu Optical Services Data Center Cable Termination Station Submarine DCI Dual Peering with Shared Router Page 4 of 5 us.fujitsu.com/telecom Application Note Data Center Interconnect Complete Solutions: Hardware, Software and Services Software Control for DCI Applications Services Expertise to Support Successful Implementation The Fujitsu Virtuora suite of SDN/NFV software products provides software-defined, virtualized network control, management and orchestration.
