    Overcoming typical barriers

    Q & A

  • Challenges With Desktop Computing

    The “thick-client” PC has been the workhorse of desktop computing. It has offered the best available combination of price, performance, and capabilities. However, for many use cases thick- client PCs are less than an ideal solution. Among their drawbacks: •Difficult to manage •High total cost of ownership •Difficult to protect and secure data •Inefficient resource utilization

  • Virtual Desktops - Architecture


    Thin Client



    Server Pool

    Storage Pool


    Desktop VMs

     Separate the physical endpoint from the logical desktop

     Host the logical desktop in a data center

     Access the logical desktop over the network

    Data Center

    Operating System

    User Data


  • Typical Business Drivers for Desktop Virtualization

    Microsoft Windows 7 Migration

     Reduce migration costs

     Reduce application incompatibility

     Extend life of existing desktop software

    Contractors and Employee-Owned IT

     Deploy and manage a desktop image on employee-owned assets

     Centrally control desktops and data

     Provide separation between corporate and personal desktops

    Remote Office and Branch Office

     Reduce costs by managing desktops and users centrally

     Centrally control sensitive data

     Streamline desktop and application deployment

    Business Process Outsourcing

     Reduce costs by managing desktop applications and users centrally

     Centrally control sensitive data

     Streamline desktop and application deployment

    Business Continuity and Disaster Recovery

     Support end-users working from remote locations

     Ensure desktops are available 24 x 7

     Quickly provision new desktops

    Mobile Users

     Enable desktop access regardless of network connection

     Extend security and control of offline users

     Use local device resources

    tenancy concerns • ‘Trustworthiness’

    User access & authentication ?

    User Profiling ?

    Anti Virus

    Data Security ?

  • Securing the Infrastructure: A Simple Checklist

    • Standard security infrastructure

    • Harden the platform based on the respective technologies

    • User Authentication and User Profiling

    • Clear boundaries of management

    • End Client Protection

    • Access Control policies

    • And finally ….Monitoring & Compliance


  • Cisco Datacenter Optimization for Desktop Virtualization

  • Simplified Management • Embedded single point of management and provisioning • Visibility and control across datacenter organizations • Infrastructure policy management and compliance

    Scalability and Rapid Deployment

    • Massive Scalability: Scales to 320 servers (Thousands of Virtual Desktops)

    • Simple Operation: Start in Minutes, Scale in Seconds • (Cisco Service Profiles)

    Built for Virtualization • Fine-grained control, portability, and visibility

    of network, compute, and storage attributes • More than double the memory capacity of competing systems

    (60% more virtual desktops per blade)

    Unified Fabric Infrastructure • Wire once, low latency FC and Ethernet • Less than half the normal number of adapters, switches (LAN

    and SAN), cables (1/3 less infrastructure cost)

    Cisco UCS - Ideal Platform for Desktop

    Virtualization The Cisco UCS is designed to dramatically reduce datacenter total cost of ownership while simultaneously

    increasing IT agility and responsiveness.

  • Desktop Pools with QoS on UCS

  • Video inside a Desktop Session

    • 1 Pixel = 3 Bytes • 1 Row = 3 Kbytes (3 Bytes X 1024 ) • 1 Screen = 2 Mbytes ( 768 X 3 Kbytes) • 1 Sec of MPEG Video = 2 Mbytes X 25 = 50 Mbytes /sec

    1024 Pixels (24 Bits)

    768 Pixels (24 Bits)
