GreenPages Technology Solutions is a national technology consulting and integration company founded in 1992 and headquartered in Maine. It offers services such as virtualization consulting, operational readiness assessments, and managed services. The document discusses the evolution of data center architectures from centralized to distributed to virtualized (DC 1.0 to 2.0 to 3.0). It also covers 10Gb networking technologies like Data Center Ethernet and how the Cisco Nexus platform and Nexus 1000V virtual switch can provide a virtual machine-aware network for faster VM deployment, richer services, and increased efficiencies.

7. 10Gb – Reaching the Tipping Point
Link Cost Reductions –
Advanced switch platforms (Nexus), 3rd Gen Silicon for
advanced 10GbE NICs and low cost copper connections
VMWare Density Driving Demand
Server Consolidation is loading servers with 4, 8, 10, 16, 30
VMs which require populating servers with 4, 8, 10+ 1Gb NICs
10GbE connections are cheaper, easier to install and manage
New Platform Capabilities
Previous Server platforms had difficulty driving 1Gb links, but
new servers with 4-8 cores can drive multiple 10Gb links

9. What is Data Center Ethernet?
Data Center Ethernet is an architectural collection of Ethernet
extensions designed to improve Ethernet networking and
management in the Data Center.
Cisco is showing innovation while working through the
standardization process with these extensions in open
standards forums.

10. Data Center Ethernet Overview
Feature / Standard Benefit
Enable multiple traffic types to share a common
Priority Flow Control (PFC)
Ethernet link without interfering with each other.
IEEE 802.1Qbb
Ability to support storage traffic
Grouping classes of traffic into “Service Lanes”.
Bandwidth Management
Enable consistent management of QoS at the
IEEE 802.1Qaz
network level by providing consistent scheduling
Congestion Management End-to-end congestion management for
L2 network
IEEE 802.1Qau
Data Center Bridging Management protocol for Auto-negotiation for
Exchange Protocol (DCBX) Enhanced Ethernet capabilities (Switch to NIC)

13. 10Gb Cabling Characteristics
Costly Optical Connections – Fibre cheap – XCVRs NOT
Require transceiver options – Xenpak, X2, XPF, SFP+ with costs
ranging from $1,600 to $3,000+ - PER SIDE
Copper - Cisco offers CX1 – Twinax solutions
Short range options use CX1, CX4: No standard RJ-45 solutions
until a new generation of low power PHYs emerges in 2010.
RJ-45 solutions require new cable options to address induced
noise to transmit beyond 30m. Requires Engineering
Vendors converging on SFP+ for lower TCO until RJ-45 emerges
End of Row vs Top of Rack
Distance limits 10Gb EoR solutions to Optical – which is fine for
Uplinks – but cost prohibitive (Transceivers) vs ToR with Copper
10GbE Cabling Favors ToR Solutions until 2010

18. VN-Link Brings VM Granularity to the Network
Problems:
VMotion
• VMotion may move VMs
across physical ports—policy
must follow
• Impossible to view or apply
policy to locally switched
traffic
• Cannot correlate traffic on
physical links—from multiple
VMs
VLAN
101
VN-Link:
•Extends network to the VM
•Consistent services
•Coordinated, coherent
management

19. So what is VN-Link?
VN-Link, or Virtual Network Link, is a term which describes a new
set of features and capabilities that enable VM interfaces to be
individually identified, configured, monitored, migrated and
diagnosed.
The term literally refers to a VM VNIC VNIC
Hypervisor
specific link that is created
between the VM and Cisco
switch. It is the logical
equivalent & combination of a
NIC, a Cisco switch interface VETH VETH
and the RJ-45 patch cable that
hooks them together.
VN-Link requires platform support for Port Profiles, Virtual Ethernet
Interfaces, Virtual Center Integration, and Virtual Ethernet mobility.
