  • 3. Business Challenges Data growing at 62% annually to 800,000 Petabytes Mandates to reduce OPEX and CAPEX Hardware underutilized or overutilized Reduce power consumption and footprint Faster response to business changes In addition deal with all of this across multiple data centers Virtualization is not an option, it is a requirement Copyright 2010 EMC Corporation.

  • 4. Defining Virtualization Virtualization provides logical views of physical resources while preserving the usage interfaces for those resources. Virtualization removes physical resource limits and improves resource utilization. Copyright 2010 EMC Corporation. All rights reserved. 4
  • 5. Virtualization Comes in Many Forms Virtual Virtual Virtual Memory Servers Servers Each application sees its own Each application sees its own logical logical memory, independent of server, independent of physical physical memory servers Virtual VirtualNetworks Storage Each application sees its own logical Each application sees its own logical network, independent of physical storage, independent of physical network storage Copyright 2010 EMC Corporation.

  • 6. Virtualization Comes in Many Forms Virtual Memory Physical Memory Each application sees its own logical memory, independent of App physical memory App App Benefits of Virtual Memory Swap Space Remove physical memory limits Run multiple applications at once Copyright 2010 EMC Corporation.

  • 7. Virtualization Comes in Many Forms Virtual Virtual Virtual Memory Servers Each application sees its own Each application sees its own logical logical memory, independent of server, independent of physical physical memory servers Virtual VirtualNetworks Storage Each application sees its own logical Each application sees its own logical network, independent of physical storage, independent of physical network storage disks Copyright 2010 EMC Corporation.

  • 8. Virtualization Comes in Many Forms Benefits of Virtual Networks Common network links with access VLAN A VLAN B VLAN C control properties of separate links. Manage logical networks instead of physical networks. Virtual SANs provide similar benefits for storage area networks. VLAN Trunk Virtual Switch SwitchNetworks Each application sees its own logical network, independent of physical network Copyright 2010 EMC Corporation. All rights reserved. 8
  • 9. Virtual Networks Unify Network Traffic VLANs: different classes of traffic share network iSCSI, FCoE, NFS, CIFS, web, etc. Ethernet LAN Unification: Reduce cables, interfaces, etc. Limited interaction among traffic classes Controls (access and QoS) for each traffic class FCoE switches iSCSI/FCoE Storage Switch A Switch B FC SAN Ethernet Servers FC Copyright 2010 EMC Corporation.

  • 10. Distributed Virtual Networks: Virtualization across Locations OTV [Overlay Transport Virtualization] (Cisco) Overlay network extends VLANs over arbitrary network connectivity Works over any WAN type dark fiber, MPLS, IP No network architecture change in datacenter just add OTV edge devices Seamless add/ drop of edge nodes w/o reconfiguring other edge notes Distributed network virtualization VLANs based on physical network resources across multiple locations Core IPA IPB West East IPC South Copyright 2010 EMC Corporation.

  • 11. Defining Distributed Virtualization Distributed Virtualization provides logical views of distributed physical resources while preserving the usage interfaces for those resources. Distributed Virtualization removes location barriers and physical resource limits, improving resource utilization. Copyright 2010 EMC Corporation. All rights reserved. 11
  • 12. OTV Use Case Data Center Growth ConstraintsProblem: Primary data center maxed out (space, cooling and power)Requirement: Seamlessly extend clusters & workload across datacentersChallenge: Rapidly establish network interconnect between data centers Deployover One
