Cabling for Next Generation Data Center Technologies BRKDCT-2998 Presentation_ID © 2009 Cisco Systems, Inc All rights reserved Cisco Public Cabling for Next Generation Data Center Technologies Abstract: An understanding A d di off facilities f ili i and d iits restrictions, i i and d the h resulting l i iimplication li i on the h placement of switches, servers, racks/cabinets and cabling media is critical to the success of the planning and deployment of a Greenfield data center The transition from 1G to 10GE and the evolution toward Unified Fabric environments have close ties with the physical critical infrastructure infrastructure The next generation data center architecture is as good as the flexibility provided by physical facilities Therefore, a facilities architecture that enables network layer architecture flexibility will provide customer with network deployment options at enable modularity and flexibility The session explores server access layer network architecture deployment models for Top-of-Rack (ToR) and Middle of Row (MoR) / End-of-Row (EoR), Distributed Access p to cabling g strategy gy to support pp 1G to 10GE migration, g , 10GE Fabric ((DAF)) with respect transceiver form factors, 40GE/100GE infrastructure support, horizontal and in rack cabling Modular design methodology leveraging the POD concept for repeatable access layer building blocks to support server access and aggregation will be explored with respect to impact on the critical facility cabling architecture BRKDCT-2998 © 2009 Cisco Systems, Inc All rights reserved Cisco Public Agenda ƒ Data Center Tends Affecting Cabling ƒ Media Options for 1GE - High Speed Ethernet Migration g Models ƒ Data Center Access Cabling ƒ DC Access Cabling Options ƒ Summary BRKDCT-2998 © 2009 Cisco Systems, Inc All rights reserved Cisco Public DC Facilities Top of Mind Complexity, Cost, Power, Cooling Increased Efficiency, Standards Compliance Simpler Operations Reliability, y, Availabilityy Scalability, y, Flexibility, y, Management, Security Technology adoption, Future Proofing Modularity, Mobility BRKDCT-2998 © 2009 Cisco Systems, Inc All rights reserved Cisco Public Data Center Architectures and Design Facilities? ƒ Complex process involving several correlated inputs ƒ Optimizing one area can significantly impact others ƒ Careful consideration of current and future needs required to maximize Investment in Data Center Facilities & infrastructure Cabling?
