1 The Role of Networking in a Virtualized World Sponsor Technology Roadmap Kevin Ryan Director Data Center Solutions

2 Data Center Trends The New Computer Data center capacity, not server capacity, is the new metric Consolidation High Computational Density Physical Location Consolidation Green Efficient Power Management Virtualization On Demand Provisioning Hardware Independence / High Availability Location Independence Network / Storage Convergence

3 Virtualization: A Networking Problem. And Opportunity The Dissolving Network Edge Network boundary between switch and server has blurred Switching at multiple levels Virtual switch NIC cards Blade switches Network switches Distributed virtual switches All of which creates complexity

4 Virtualization: A Networking Problem. And Opportunity VM: Force-Fits Dynamic into a Static network VM Mobility requires network configuration to follow VMs VLAN, QoS, ACLs, rate limiting tied to VM, not network port Best practices are conflicting Flat L2 versus segmented Creating organizational tension and confusion Requires coordination between server & network administrators

5 Virtualization: A Networking Problem Who owns the networking configuration? Server and network administrators traditionally distinct Server administrators not skilled at network configuration Dealing with inconsistencies in server and network configuration Increased likelihood of errors Troubleshooting, maintenance require direct coordination across groups Shifting locus of control

6 Virtualization: A Networking Opportunity Network Topology Reduce Network Tiers Integration with VM Platforms Network Profiles for VMs Provision 1,000s of Switches across Multiple Sites Direct Attach Automated Configuration User Generated Scripts Bandwidth and Performance Fixed and Modular Platforms Heterogeneous (Best-of-Breed) support for Virtual Machines 1G 10G 40G 100G XML-enabled Infrastructure Open APIs Robust and Flexible Stacking Single pane of glass management Application Awareness & Support Program & Application Integration

7 Efficiently Manage Virtualization Make the network VM Aware Switch detects movement of virtual machines Dynamically provision network parameters for the virtual machine QoS, ACLs, Rate Limiting Enable fast provisioning, migration and deprovisioning with confidence Deliver the valuable control at the network layer in the virtualized world Bridge the organizational divide Extreme Networks, Inc.

9 VM Mobility Issues Today Network has Zero Visibility into VM Lifecycle Server Admin Initiate Network Admin Virtual Machine Manager e.g. Switch Port Config IP: MAC: 00:0A QoS: QP7 ACL: Deny HTTP Switch Port Config None or Disabled When a VMotion or Live Migration occurs automatically or initiated by server admin, the network admin has NO visibility into VM location or when the movement occur NIC VM1 IP: MAC: 00:0A Hypervisor NIC Hypervisor Result: The VM moves to a destination switch port that is incorrectly configured to deliver network services to the specific VM

10 XNV: Network Visibility into VM Lifecycle Query Location-based VM awareness at the network level for efficient VMotion or Live Migration Server Admin Initiate Network Admin Virtual Machine Manager e.g. VM info Switch Port Config Switch Port Config Virtual Port Profile IP: IP: MAC: MAC: 00:0A 00:0A QoS: QoS: QP7 QP7 ACL: ACL: Deny Deny HTTP HTTP Switch Port Config None or Disabled Through XML integration: Pull inventory from VMware vcenter Locate VMs on network switches Show Inventory VM Switch Port Mapping Define Virtual Port Profile (VPP) Assign (VPP) to VMs and Distribute Respond to VM motion occurrences NIC VM1 IP: MAC: 00:0A Hypervisor NIC Hypervisor Result: Both the VM and the Virtual Port Profile move to the destination switch port. Networklevel visibility into VM movement is achieved to deliver better SLA.

11 Scale: Simplify by Eliminating the vswitch Embedded soft switch (Today) Large growth in VMs introduces switch functionality on server Proliferation of switching infrastructure in network Soft Switch (vswitch) in server Each vswitch needs management Direct Attach (Future) Industry support for standardization 802.1Qbg compliant Moves switching functionality back to the network Reduces management complexity Increases performance & security Direct Attach Switching Architecture Direct Attach Switch Infrastructure

12 Direct Attach: Eliminate the vswitch Virtually Reducing Network Tiers Minimal traffic provisioning (if any) is done at the vswitch. vswitch Data Center Core VM1 VM2 Today s Inter-VM Switching

13 Direct Attach: Eliminate the vswitch Virtually Reducing Network Tiers Inter-VM traffic provisioning at the network-level. Dynamic ACLs QoS Rate-limiting Anomaly Detection etc Direct Attach Enabled Switch Data Center Core vswitch VM1 VM2

14 Direct Attach: Eliminate the vswitch Virtually Reducing Network Tiers Inter-VM traffic is transmitted and received on the same network physical port. VM2 CPU and network utilization severely impacted, due to DoS attack. CLEAR-Flow enabled to dynamically provision/block DoS traffic. VM2 CPU and network utilization reverts to healthy. Direct Attach Enabled Switch Guest OS: Ubuntu Active applications: gnome-system-monitor for network and CPU utilization hping to generate DoS attack targeted at VM2 Guest OS: Ubuntu Active applications: gnome-system-monitor for network and CPU utilization tcpdump to monitor attack traffic from VM1 VM1 VM2 Host: Fedora 12 Hypervisor: QEMU-KVM
