Data Center Networking
This course provides an insight to the students on design guidance, configuration examples and best practices with respect to data center networking. This course also deals with current data center architectures, new technologies adopted to create modern data center architecture, and merits and demerits of the same. This course examines these new technologies and demonstrates how consolidation can be realized using a unified network approach.
On successful completion of this course, the learner will be able to
- Critically discuss data centre networking technologies and protocols.
- Evaluate key concepts in modern Layer 2 & Layer 3 data centre networks.
- Research a topic related to networking technologies in modern data centers.
- Design, build and configure complex routed and switched networks.
- Justify the implementation of networking solutions in a virtualized environment.
- Evolution of Data Centre Design: Design for flexibility, scalability, environmental control, electrical power, flooring, fire protection, security, network infrastructure. Energy use and greenhouse gas emissions. Requirements for modern data centers, high availability and Service Orientated Infrastructures (SOI). Modern data centre use case studies.
- Data Centre Architectures: Network connectivity optimization evolution: Top of rack (TOR), end of rack (EOR), scale up vs scale up, solutions that reduce power and cabling. Data Centre standards; TIA/EIA-942. Structured cabling standards, fibre and copper cabling characteristics, cable management, bandwidth requirements, I/O connectivity.
- Server architectures: stand-alone, blades, stateless, clustering, scaling, optimization, virtualization. Limitation of traditional server deployments; modern solutions. Applications; database, finance etc. Redundant Layer 2 and Layer 3 designs. Case studies.
