  1. Transforming Server Virtualization with Cisco VN-Link Belmont Chia Consulting System Engineer Data Center Network Architecture

  2. Agenda • Trends with Server Virtualization • Cisco VN-Link Introduction • Cisco Nexus 1000V • Overview & Architecture • Deployment Scenarios

  3. Server Consolidation And Virtualization Are #1 & #2 Spending Priorities Source: Goldman Sachs CIO Survey 10% of server workloads virtualized in 2008; forecast to be 50%-60% in next 5 years Source: Industry analyst reports Desktop Virtualization Gaining Traction as Tool to Address Desktop Manageability, Security and Cost Source: Goldman Sachs IT Spending Survey Increasing Use of VMotion and DRS resulting in Multiplicative Increase in Complexity Source: Cisco Expanding Role of Server Virtualization

  4. Networking Challenges to Scaling VM Deployments Security and Policy Enforcement Operation andManagement OrganizationalStructure Applied at physical server—poor granularity Security and policy doesn’t follow VM Lack of VM connection visibility Inability to troubleshoot and audit Blurs boundaries between roles Creates loss of productivity & compliance challenges

  5. Nexus 1000V Introducing Cisco Virtual Network Link Virtualizing the Network Domain Policy Based VM Connectivity Mobility of Network & Security Properties Non-Disruptive Operational Model LAN Cisco Nexus 1000V (Software Based) Nexus 5000 with VN-Link (Hardware Based) • Cisco switch for VMW ESX • Compatible with any switching platform • Leverages Virtual Center for server admin; Cisco CLI for network admin • Scalable, hardware based, high performance solution • Standards driven approach to delivering hardware based VM networking • Combines VM & physical network operations into 1 managed node Server Server VM #1 VM #2 VM #3 VM #4 VM #1 VM #2 VM #3 VM #4 VMW ESX VMW ESX Initiator NIC NIC Nexus 5000 Nexus 1000V Two Complimentary Models to Address Evolving Customer Requirements
