29. Wave 2 of 10GbE Market Adoption 10GbE IP Storage Web Giants x86 & Unix Rack Servers 65% of Server Shipments More that 2X the Revenue Opportunity Romley from Q4:11 to Q2:11 Modular LOM on Rack More Cards vs. LOMs Cisco, Juniper, Brocade announced Multi-Hop FCoE in last 90 days 10GbE NAS, ISCSI & FCoE Convergence Next Gen Internet Scale Applications (Search, Games & Social Media) Container & High Density servers migrating to 10GbE Growing to 15% of Servers Wave 2 – More Than Doubles 10GbE Revenue Opportunity CY12/13

30. The 10Gb Transition – Cross Over in 2012 Source Dell Oro Group

31. #1) Switch Architecture Top of Rack Modular unit design – managed by rack Servers connect to 1-2 Ethernet switches inside rack Rack connected to data center aggregation layer with SR optic or twisted pair Blades effectively incorporate TOR design with integrated switch SAN Eth Aggregation FIBER FIBER FIBER SERVER CABINET ROW

32. Switch Architecture End of Row Server cabinets lined up side-by-side Rack or cabinet at end (or middle) of row with network switches Fewer switches in the topology Managed by row – fewer switches to manage SAN Eth Aggregation FIBER FIBER FIBER FIBER COPPER SERVER CABINET ROW

33. #2) 10Gb LOM on Rack Servers vs. Typically limited I/O expansion (1-2 slots) Much cheaper 10G physical interconnect – backplane Ethernet & integrated switch – leading 10G transition Earlier 10G LOM Generally more I/O & memory expansion More expensive 10G physical interconnect Later 10G LOM due to 10GBASE-T

34. Today’s Data Center Typically Twisted Pair for Gigabit Ethernet Some Cat 6, more likely Cat 5 Optical cable for Fibre Channel Mix of older OM1 and OM2 (orange)and newer OM3 (green) Fibre Channel may notbe wired to every rack #3) Cables

35. Mid 1980’s Mid 1990’s Early 2000’s Late 2000’s 100Mb 1Gb 10Gb 10Mb UTP Cat 5SFP Fiber SFP+ Cu, Fiber X2, Cat 6/7 UTP Cat 5 UTP Cat 3 TransceiverLatency (link) Power(each side) Cable Distance Technology Copper Twinax 10m ~0.1ms ~0.1W SFP+ Direct Attach 10GBase SR (short range) Optic Multi-Mode 62.5mm - 82m50mm - 300m ~0 1W Optic Single-Mode 10GBase LR(long range) 10 km Var 1W 10GbE Cable Options Cat6 - 55mCat 6a 100m Cat7 -100m ~2.5W (30m)~3.5W (100m) ~1W (EEE idle) Copper Twisted Pair ~2.5ms 10GBASE-T

36. 3X Cost and 10X Performance

37. 10G BASE-T Will Dominate IT Connectivity Crehan Research 2011

38. New 10GBASE-T Options Top of Rack End of Row SFP+ is lowest cost option today Doesn’t support existing gigabit Ethernet LOM ports 10GBASE-T support emerging Lower power at 10-30m reach (2.5w) Energy Efficient Ethernet reduces to ~1w on idle Optical is only option today 10GBASE-T support emerging Lower power at 10-30m reach (2.5w this year) Can do 100m reachat 3.5w Energy Efficient Ethernet reduces to ~1w on idle

47. Volume x86 systems High End Unix Systems To Converge or Not To Converge? Best business case for convergence Systems actually benefit by reducing adapters, switch ports and cabling Limited convergence benefit Typically large number of SAN and LAN ports System may go from 24 Ethernet and 24 Fibre Channel ports to 48 Converged Ethernet ports Benefits in later stages of data center convergence when Fibre Channel SAN fully running over Ethernet physical layer (FCoE)

48. #7) Select 10Gb Adapter 10Gb LOM becoming standard on high-end servers Second adapter for high availability Should support FCoE and iSCSI offload for network convergence Compare performance for all protocols

49. Convergence Means Performance 40 Gb/Sec 900K IOPS/Sec Wider Track: More Data Lanes No Virtualization Conflicts Capacity for Provisioning Faster Engine: More Transactions More VMs/CPU QOS you demand Performance for Storage 24

50. #8) Bandwidth and Redundancy NIC Teaming – Link Aggregation Multiple physical links (NIC ports) combined into one logical link Bandwidth aggregation Failover redundancy FC Multipathing Load balancing over multiple paths Failover redundancy Core Core Core Core a b Redundancy Redundancy Poor Density c d

51. NETWORK FRAMEWORK SAN LAN NETWORKCONVERGENCE #9 Management Convergence Future Proof SAN LAN Investment Protection Protects Your Configuration Investment Protects Your LAN & SAN Investment Protects Your Management Investment

52. Convergence and IT Management Traditional IT management Server Storage Networking Convergence is latest technology to perturb IT management Prior: Blades, Virtualization, PODs Drives innovation Storage Networking Server/Virtualization

53. #10) Deployment Plan Upgrade switches as needed to support 10Gb links to servers Plan for network convergence with switches that support DCB Focus on new servers Unified 10GbE platform for LOM, blade and stand-up adapters
