 Provisioning is slow
 Placement is limited
 Mobility is limited
 Hardware dependent
 Operationally intensive

26. Who Am I?
• Jeremy Hanmer (@fzylogic)
• 13 years of experience with DreamHost
• System Engineer -> Network Engineer ->...
• ... VP Security -> Cloud Architect
• Focusing on OpenStack and Network
Virtualization

28. Why Virtualize?
• Customers deserve it
• Better Security (Isolate customers from one another)
• Live Migration (Zero-downtime maintenance!)
• Replicate their existing IP addressing schemes
• Easier administration
• Live Migration (Hypervisor maintenance becomes easy)
• Much easier to know what’s going on on the network
• Automating VLAN provisioning STINKS and doesn’t scale
• We’re now able to migrate workloads to avoid hot spots

29. Why VMware?
• Confident in their team
• Roadmap (It included IPv6!
I’m told it’s getting close!)
• Easy integration of our own Layer 3 services
• Community presence in OpenStack
is awesome
• Emphasis on ease of troubleshooting
• Super great support from the beginning

30. Why Cumulus?

31. Physical Network Design
• IPv6 Native
• Storage network is 100% IPv6
• Customers all receive a /64 of public IPv6 space
• Layer 2 domains terminate at the TOR
• OSPF v2/3 running on every switch
• 10G Ethernet to every server
• 40G Ethernet between spines
• Dedicated networks for storage (one frontend, one backend),
NSX, and administration
• Simple!
• VRRP, QFabric, HSRP often cause more problems than they fix
• Debugging Layer 3 is easy. Debugging Layer 2 is not

32. Rack Architecture

33. Virtualization Workflow
•

•
AKA: Why this is all so awesome

34. The Future!
• Migrate to NSX’s L3 services
• Just waiting for IPv6 to ship with BGP support
• Get Chef running on the Cumulus gear
• Hasn’t been a priority because of the nearly
identical configs
• Move to a full mesh architecture that wasn’t
possible before
