CASE STUDY – DATA CENTER INTERCONNECT
USING DWDM OPTICAL TRANSPORT
AGENDA
o Business drivers and solution overview
o Why DWDM as an interconnect?
o ˝High End˝ DWDM
o Network Design & Deployment of ONS
15454 M6 (RING, P-t-P)
o Next steps!
o Summary
BUSINESS DRIVERS
Goal : Identify gaps between “To Be” and “As Is” Architecture and prioritize activities.
BUSINESS DRIVERS
o Disaster recovery
Protecting Data Trough Offsite Data during unexpected event
Replication and Backup
o Business Continuance
Restoration of Business After a Failure
Data Center Interconnect LAN & SAN Extension
o Business Resilience
Continued Operation of Business During a Failure
o Regulations driving Data Protection
Federal laws and regulations dealing with electronic records (PCI, Basel II
etc.)
o IT services agility and flexibility
Virtualization, Consolidation and Cloud services (XaaS)
WHY DWDM AS AN INTERCONNECT?
WHY DWDM AS AN INTERCONNECT?
Interconnect Challenges that were avoided:
o Complex operations
o Transport dependent
o Bandwidth management
o Failure containment
Advantages:
o Scalability
o Low Latency
o Convergence
o Increase Transmission density
o Traffic separation at Layer 1
o Solve distance limitation
o Service Protection
o OAM&P
˝High End˝ DWDM
o Greater Scalability
Support for 40Gbps and 100G bps transport
Service Flexibility (SDH/Ethernet, SAN & Video services)
Covers all requirements for enterprise BC/DR solutions, metropolitan DWDM, LH & ULH
o Number of Channels & Flexibility
DWDM – 40/80/112 (80 in C-band & 32 in L-band)
ROADM-based optical infrastructure providing built-in scalability, flexibility, and easy expansion
o Wide Range of Topologies supported
Point to Point, Ring, Multi-Ring, Mesh, Bi-Directional/Single Fiber Design
o Design tool
