  1. Data Center Best Practices Randy Cross Infrastructure & Fabric Technologies

  2. Data Center Trends • Confusion • Technology Soup • SDN, cloud, fabric • Hype • Cisco • Disappointment • Islands • Integration • Orchestration • Solution Focus • Simplification • Monoliths • Disaster Avoidance • Point Trends • ToR • Fixed Core • Modular Design

  3. “No Soup for you!” Software-Defined Networking is a work-in-progress… Energy Efficient Ethernet IPv6 Network Access Control Telepresence WanOp Unified Communications and Collaboration MEF MDM Network Performance Monitoring 802.11n SIP ADC SAN Fault Monitoring MPLS Location Awareness … Geo VM Moves DCB Video Conf Infra Fabrics APM FCoE SDN Virtual Switch Change Management 802.11ac Which has a long way to go to prove successful

  4. Where to Begin? • The Problem • Complexity • More with Less • Or about the same • Resource Capacity • Refresh • New Builds • Goals • Enable Business Growth • Ensure Agility • Maximize Assets • Simplicity

  5. Enable Business Growth • Solutions • No more Silos • User Focused • Tied to Growth Initiatives

  6. Ensure Agility • Integrate the Stack • Virtualization EVERYWHERE • Pick the Right Technologies • Policy/Controller • Fabric • Storage • WOC, ADC, Security, etc • HVAC • Pick the Right Devices • ToR • Fixed vs Modular Core • Open Rack vs Blade Servers Row A Row B Row C Rack 2 Rack 3 Rack 4

  7. Maximize Assets • Modular Design • Greenfield • Virtual Modular Design • DC to DC • Disaster Avoidance • User Experience Data Center 1 Avaya Fabric Connect SPB-mode DToR Flexible: up to 480 Switches, 15,360 x 10GbE Ports, 259.2Tbps

  8. Proposed Recommended Link Speed Metrics

  9. Example: Highest Available BW SPB-mode DToRFlexible Interconnect: up to 200 Switches (6,400 10GbE Ports & 112 Tbps) Rack 1 Rack 2 Rack 3 Rack 4 Row A VSP 9000 A VRRP Master or RSMLT Row B Using defined SPB Path Costs Using manually assigned SPB cost metrics, traffic is assured to always use the most effective path. Examples: Row A Rack 1 L2 to B3 = 17 Row B Rack 4 L2 to C2 = 17 Row D Rack 2 L2 to A4 = 35 Row A Rack 4 L2 to D1 = 32 Row A Rack 1 (L3 traffic) to VSP9K A VRRP Master = 40 (5+35) VSP9K A (L3 traffic) to Row D Rack 4 = 35 (direct 10Gig) VSP9K A (L3 traffic to Row D Rack 1 = 40 (35+5) Row C VSP 9000 B VRRP Backup or RSMLT Row D • Rear Port Mode with SPB • FI Port legend: • Black – 120/240 Gbps • Red – 80/160 Gbps • Blue – 40/80 Gbps • (Full-Duplex/Aggregate) MLT NNI • SBP Manually Assigned “Highest Available Bandwidth” Cost Metrics • Black = 3 • Red = 5 • Blue = 9 • 10Gig = 35

  10. Example: Most Equitable SPB-mode DToRFlexible Interconnect: up to 200 Switches (6,400 10GbE Ports & 112 Tbps) Rack 1 Rack 2 Rack 3 Rack 4 Row A VSP 9000 A VRRP Master or RSMLT Row B Using defined SPB Path Costs Using manually assigned SPB cost metrics, traffic is assured to always use the most effective path. Examples: Row A Rack 1 L2 to B3 = 25 Row B Rack 4 L2 to C2 = 15 Row D Rack 2 L2 to A4 = 25 Row A Rack 4 L2 to D1 = 30 Row A Rack 1 (L3 traffic) to VSP9K A VRRP Master = 50 (15+35) VSP9K A (L3 traffic) to Row D Rack 4 = 35 (direct 10Gig) VSP9K A (L3 traffic to Row D Rack 1 = 50 (35+15) Row C VSP 9000 B VRRP Backup or RSMLT Row D • Rear Port Mode with SPB • FI Port legend: • Black – 120/240 Gbps • Red – 80/160 Gbps • Blue – 40/80 Gbps • (Full-Duplex/Aggregate) MLT NNI • SBP Manually Assigned “Most Equitable Load Sharing” Cost Metrics • Black = 5 • Red = 5 • Blue = 5 • 10Gig = 35

  11. Multi Data Center Optimization VRRP-BM BEB’s w/ L2 VSN for servers + L3 VSN for network access BCB or BEBs BCB or BEB’s BEB’s w/ L2 VSN for servers + L3 VSN for network access Data Center A Data Center B 10.10.10.2 10.10.10.4 VLAN 10 VLAN 10 NNI NNI NNI IST/NNI IST/NNI VLAN 10 VLAN 10 ESX Host ESX Host NNI NNI NNI 10.10.10.5 10.10.10.3 VRRP VR 10.10.10.1 VM Gateway is 10.10.10.1 L3 VSN I-SID 500 supporting VRF routing to multiple locations VLAN 600 VLAN 200 L3 ISID 500 L3 ISID 500 ISID 10 VLAN 500 L3 ISID 500 VLAN 300 ISID 10 ISID 10 ISID 10 VLAN 400 VLAN 100 Client

  12. Simplicity • Automation • Orchestration • SDN • Solutions • Full Stack • Monolithic vs Best-of-Breed • Support • Trust

  13. Summary • Don’t get sucked into the drama! • K.I.S.S. • Be Farsighted • Get Your Money’s Worth • Be a Hero: Grow the Business Simplicity is the ultimate sophistication. - Leonardo Da Vinci
