22 The Promise of Utility Computing Virtual I/O Cluster computing w/ RDMA Compute Virtualization LAN, WAN, Internet Access Networked application services Integrated security Application or Policy Storage Virtualization Fabric-assisted Applications Data Replication Services Racks of compute resources virtualized in the data center Allocated to applications dynamically Network, storage and compute services applied dynamically to pools of resource 22

23 What is VFrame? Cisco s end-to-end virtualization, provisioning manager Virtualization What is VFrame Cisco s data center-wide virtualization software suite Enterprise software package that runs in the data center Delivers the end-to-end manageability, control, and virtualization benefits of the mainframe on top of today s commodity components and the Cisco IIN Provides virtualization, orchestration, and provisioning for the data center resources that sit between the OS and the wire 23

CSM Load Balancer Campus/ WAN/VPN Catalyst 6500 FWSM Firew all VFrame picks server with right criteria to run application and boots server VFrame gives new server right VLAN, VSAN and LUN info so it can find/be found by right clients and storage VFrame provisions security policies to FWSM VFrame provisions CSM to add new server to load balancing pool 25

26 Utility Computing example Server Failover 1. Physical server fails Group 1 Group 2 x Standby Pool 4. New server restarts in new group 2. VFrame detects fault 3. VFrame programs MDS to map standby physical server to LUN Storage Network Campus/ WAN/VPN 26

27 Utility Computing example Add Capacity on Demand 1. Application monitors issue triggers to VFrame 3. Standby servers restart in new group with new mappings Group 1 Group 2 Standby Pool 2. VFrame programs MDS to add new servers from standby pool Campus/ WAN/VPN Storage Network 27

28 VFrame Benefits Manage the data center from a service-oriented, application-centric perspective Eliminate number of layers/devices required to be touched to provision or modify Treat the entire data center infrastructure (from the OS to the wire ) as one manageable entity of shared virtualized resources (Virtual Mainframe) Expose a single orchestration and provisioning interface for all data center infrastructure Dramatically reduce TCO 28
