FabricPath Flexibility

• The network can evolve with no disruption

• Need more edge ports?

• Need more bandwidth?

→ Add more leaf switches

→ Add more links and spines

Benefits • Ethernet LAN Extension over any network

• Multidata center scalability

• Seamless overlay—no network re-design

What’s new• Selective Unicast Flooding for unidirectional MAC

addresses• OTV VLAN translation*• Multiple Uplinks• 10 Overlay, 10 sites dual-home,• 16K MACs, 2K VLANs

• L2-Multipath





Service Profiles

• Contain server state informationMAC & WWN addresses for NICs & HBAs

Boot order and BIOS parameter settings

Firmware bundle for the various hardware components

• User-definedEach profile can be individually created

Profiles can be generated from a template

• Applied to physical blades at run timeFirmware, addresses, connectivity info, and parameters in profile definition applied to blade hardware

Without profiles, blades are just anonymous hardware components
