NOTE: Solution can be scaled down by using just a single UCS B-series shelf
* 16 RU excludes the Nexus Switch element & NetApp storage
• Power, cooling, and space efficient, “Wire-once”, policy driven, self-provisioning
environment
• UCS B-series uses the Intel e2590 CPU, offering 240 cores for VM hosting in 16RU*
• Data-center class solution with flexible expansion options
– ability to scale to thousands of cores

26. Potential use of GENI in NEBULA*
26
• GENI Technology:
- Enables experiments involving multiple sites
- Isolates NEBULA experiments to a single VLAN
- Eliminates need for special HW & Address Translation
• Potential Uses:
- Multisite student collaboration on Ncore (NEBULA
Core)
- Testbed for NDP (NEBULA Data Plane) experiments
- Platform for NVENT (NEBULA extensible control plane)
- * No GENI-enabled switches on NEBULA campuses-->so
preliminary thoughts

• No other clear needs
identified yet
• Possibilities:
– Large numbers of nodes
