Transforming Server Virtualization with Cisco VN-Link

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
