Event Details
Every major networking vendor is busy promoting its own (usually proprietary) Data Center Fabric. While they're debating the architectures and proprietary nature of competitors' offerings, and solving dubious problems like large-scale bridging with pre-standard implementations, the data center users still face the problem succinctly expressed by James Hamilton: "Data Center Networks are in my Way".
However, we don't need rocket-science fabric solutions to build modern data center networks - it's possible to build large all-point-equidistant networks with no constraints on workload placement with existing gear from numerous vendors using decades-old Clos architectures.
The Clos Fabrics Explained webinar will describe the Clos architecture concepts and designs that can be used to build large layer-2 or layer-3 all-point-equidistant Data Center networks.
The webinar is ideal for architects and designers that have to look behind the vendor marketectures and build large-scale solutions that meet their business and operational requirements.
