This document discusses end-to-end data center virtualization presented by Ronnie Scott in Toronto, Canada on May 30, 2013. It begins with an overview of virtualization and definitions of virtual, then outlines the agenda which includes data center virtualization, virtual networking and cloud services, virtual compute and storage, and software defined networking. It proceeds to discuss topics like front-end data center virtualization including virtual port channels, fabric extenders, and FabricPath. Virtual networking services from the Nexus 1000V are also examined including port profiles, VXLAN, and vPath for service chaining.
34. Virtual Extensible Local Area Network (VXLAN)
• Ethernet in IP overlay network
Entire L2 frame encapsulated in UDP
50 bytes of overhead
• Include 24 bit VXLAN Identifier
16 M logical networks
• VXLAN can cross Layer 3
• Tunnel between VEMs
VMs do NOT see VXLAN ID
• IP multicast used for L2 broadcast/multicast,
unknown unicast
• Technology submitted to IETF for
standardization
With VMware, Citrix, Red Hat and Others

55. Cisco UCS C-Series Adapter-FEX and VM-FEX
UCS P81E & VIC 1225 Virtual Interface Card
• NIC partitioning to OS, 802.1BR to switch
Adapter-FEX mode: up to 16 Eth vNIC and 2 FC vHBA
VM-FEX mode: up to 96/112 vNics
• Adapter Failover: vNICs transparently mapped to standby port on primary path failure
• Security and scalability: no need to trunk all VLANs to one server interface
56. Adapter-FEX at UCS C-Series Servers
Network admin controls veth configuration and server NICs
