When covering options based on Software defined and Open Networking during engagements, I make use or a particular slide (which is fluid and always evolving)
Dell EMC Networking Approach to Software Defined and Open Networking
Software Defined and Open Networking is one of the key drivers and value props for Dell EMC Networking. At a high level, the SDN and
Leaf & Spine Vs. Spline (+ Dell EMC Networking S6100-ON)
In essence, Spline collapses the Leaf & Spine functions – much like the Functions of Core & Aggregation Layers in a traditional 3-tier topology, would
SDN Design Principles for Networks
Software Defined and Open Networking as a topic of interest, crops up in close to 80% of all Data Center opportunities I engage in. Even
VLT, Peer Routing and Routed VLT – Dell Networking
Core Config Options: First Hop/Gateway Redundancy: VRRP: Same Switch hosts VRRP and STP Master-ship for deterministic forwarding @ L2/L3 and eliminate suboptimal forwarding path. In
Force10 DCB Configuration – S4810 + MXL Sample / Example
. First, some background on DCB itself. DCB is an extension to Ethernet that enables the dedication of resources in the converged network. To ensure
Layer 2 Discards Troubleshooting – RX TX Discards
