Today’s Enterprise Requires a Modern Network
Bandwidth needs continue to grow
Evolving workloads create east-westtraffic jams
Organizations are planning for software-defined networks
Multiple vendors’ chipsetsnow exceed proprietarydesigns
Networking functionality is increasing in Linux

Data Center Networking
Dell continues to strongly push its “open” strategy, with noticeable growth in sales that include partner software solutions…” –Gartner Magic Quadrant for Data Center Networking, May 2016

Why Open Networking?
Investment Protection
Open Architecture
Re-purpose HW & SW
$Lower TCO
Array of Choices
Several options to choose the right OS for
your workload
HW can be replaced to take advantage of merchant
silicon inventions keeping the same SW. SW can be
replaced keeping the same HW.
Opportunity to standardize on HW not requiring fork-lift
upgrade
Reduced CapEx and OpEx compared to traditional
Incumbent infrastructure
A scale-out leaf-spine software-defined
architecture instead of 3-tier traditional networks
Open and agile scale-out deployment to address
future growth
Standardize HW
