Changing the Way Systems are Deployed
1
* Ghost since 1999
* Almost 4500 licenses
* Prior to 2007 license count increase of 5% or greater a year
* Last three years license count increase less then .05% a year
* Across campus over 40 images
* Half within Distributed Support Services (DSS)
* Most were essentially identical

* Request from management to consolidate images
* “Can a single base image be created for everyone’s use?”
* Too many people doing the same thing
* Do more with less
* Microsoft released Vista and its associated deployment
tool Imagex
* Microsoft changed the OS architecture
* Hardware architectures changed
*

*
* NO licensing cost
* Smaller image sizes
* Mostly non-destructive
* File & folder based
* Single instance file storage
* Disk accessible after imaging
* Multicasting needs WDS
* Extra Partitioning Step
* Extra Formatting Step

* Multicasting
* Some support areas replace large quantities of
machines all at once and pre-stage all at once
* Windows PE has limited application and
browser functionality
* Cisco NAC
* Unable to authenticate a bare metal system to
Cisco Clean Access via Windows PE

* WIM & Ghost
* Additional Ghost licenses purchased last year is less than 10%
what were purchased before switching
* Number of images reduced by more than half
* Many remaining images start with the DSS Base Image and build
on from there
* One image for each OS, including Virtual Machines
* VMWare, Virtual PC, Fusion, VMWare View (VDI), Parallels*,
Boot Camp**

* Ghost license count renewal to begin to drop
* Ghost used only in areas requiring multicast
functionality until WDS is in place
* WDS brought online July 2010
* Number of images reduced to less than 10
* Not including lab images could be as low as 4
* Non direct OIT supported departments starting
to use
*

* Vista is gone
* No department expressed interest in deploying
Vista going forward
* Windows Deployment Services
* Attached to SCCM (Configuration Manager)
* Multicast capabilities
* Wake On Lan
* Networking and IT Sec may prevent this
* Intel Active Management Technology
* Task Sequences to further modify base image
* Potentially no more “image” required
