For a system administrator at KeckObservatory, setting up a new client PC(“client deployment”) takes 3-5 man-hours.

ProblemProblem

SolutionSolutionAutomate client deployment using MicrosoftDeployment Toolkit 2008 (MDT 2008) over anetwork connection to the target client PC.

Bandwidth Usage Sample (Heavy Load)

• Doesn’t work with Zip Drives

• Requires DHCP

• Hard drive space

• Bandwidth

BenefitsBenefits Limitations Limitations•Very little user interaction

•Should reduce time todeploy

•One OS image vs. 1 perdifferent PC

•Greater flexibility ResultsResults Net time to complete client deployment: 1-2 hrsNet time to complete client deployment: 1-2 hrs

This is where you manage and store the files andtools necessary for deployment

The Task Sequence allows customization fordeployment and/or image creation to thetarget client PC

The Deployment Point creates theenvironment for deployment and allowscustomization with LTI

• Mock Server sends the OS image andsource files to Main Server

• Main Server deploys OS Image and otherfiles to Target Client PC

• Future implementation will upgradehardware for the Mock Server
