  7. 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. 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. 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) No spanning tree to manage for uplinks .Double L2 Multipath the uplink bandwidth http://www.ieee802.org/1/pages/dcbridges.html IEEE Datacenter Bridging Task Group
  11. 11. So What Good is DCE? Supports FCoE FCoE Benefits Fewer Cables Mapping of FC Frames Both block I/O & Ethernet over Ethernet traffic co-exist on same Enables FC to Run cable on a Lossless Fewer adapters needed Ethernet (10Gbps) Overall less power Network Interoperates with existing SAN(s) & SAN Mgmt Ethernet No Gateway - Stateless Fibre Channel Traffic
  12. 12. DCE >> Unified Fabric = 1 CABLE Mgmt Network Front-End Network Backup Network Unified Fabric Storage Back-End Network Network Today:- 6-10 Unified Fabric cables per server Increased Efficiency, Simpler Operations
  13. 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
  14. 14. Transmission Media: Copper Twin-AX SFP+ SFP+ Cu SFP+ Slot Characteristics: 10 Gbps bandwidth PHY = 1.8 watt Max Temp = 70 C Power Transceiver Technology Cable Distance (each side) Latency (link) SFP+ Cu Twinax 8m ~0.1W ~0.25µs µ Twin-Ax MM OM2 10m SFP+ USR 1W ~0 MM OM3 100m ultra short reach 82m MM 62.5µm SFP+ SR µ 1W ~0 300m MM 50µm short reach µ ~4W 2.5µs Cat6 55m µ 10GBASE-T Cat6a/7 100m ~8W 2.5µs µ

  18. 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. 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.
