• 600 routers• >100 Load Balancers• > 12,000 Network switches
• Including PC6248• Nseries, Sseries, Zseries Dell
Networking• Cisco Nexus and Catalyst
Networking in Numbers
Dell IT GNS Responsibilities Our Team is Made up of… Our Footprint

IntroductionDell’s network was lacking standards; required more investment; the team was fractured; processes for change and governance were absent and there was no clear architectural roadmap/ get well plan.
What were our immediate concerns?• EOL Kit• Skilling up a large team• Quality Control/ Change Mgmt• Password Mgmt• Monitoring Standards• Documentation• Support Model
Result of our problems were…• Business downtime• Productivity loss• Employee dissatisfaction• Network Blame Game• Affect Dells bottom line

Dell IT legacy campus designThree layer network model
Catalyst 3750(E)
Dell PowerConnect6248P
• Reliant on legacy Cisco Topologies and Procurement
• EOL models up and down the stack
• Dependent on Spanning-Tree for LAN protection
• Poor convergence times at the WAN layer
• Lots of outrages due to legacy config & topology failures
