Win372 - Mdt vs Wds

Windows Deployment Service (WDS) vs Microsoft Deployment Toolkit 2012 (MDT) Choose The Right ToolRhonda LayfieldSr. Deployment ArchitectDeployment Done Right

Rhonda Layfield• I live in Washington DC in the States…• Been in the IT industry for 30 years• US Navy for 7 years• Setup and Deployment MVP• Desktop Deployment Product Specialist

(DDPS)• I am self employed

• I provide training and consulting services

The Free Giveaway…

• Almost 16 hours• WAIK• MDT• WDS• SCCM

• 2 sets to giveaway• Valued at $400.00 each

The Goal For This Session• To help you decide which tool is right for

you• All tools deploy both Server and Desktop

Operating Systems (OSs)• All tools are either FREE or In-The-Box

MDT

WDS

What We Won’t Cover:

Config ManagerWindows Automated Installation Kit (WAIK)But First …

Windows Image Formats• There are two

• Windows Image• .Wim

• Virtual hard disk• .Vhd

.Wim Compared to .Vhd• .Wim

• Contain a single volume (c: d: e:)• Multiple images may be stored in a single .wim file• Single instancing

• No redundant file storage• Service image offline

• .Vhd• Contain an entire hard drive (multiple volumes)• Service image offline

Three Types of Images:Thick, Thin, Hybrid

• Thick images contain an OS and all applications• More difficult to make changes to later

• Thin images usually contain only the OS• Applications are deployed after the OS

• Group Policy deployment• MDT 2010 U1• Manually

• Hybrid images contain OS and corporate approved applications• Like line of business (LOB) applications created in-house

Add Components• Applications

• Office 2010• Adobe Reader

• Drivers• 3rd party

• Packages• OS patches• Language packs

Over Time You Will Have Multiple Images To Deploy:

• Multiple OSs• Windows 7 SP1 base DVD• Windows 7 custom Hybrid .wim image• Windows Server 2008 R2

• Drivers for different models of machines• Applications for different groups of users• So you will need a way to group components

together for a specific deployment• This is called a Task Sequence

Update The Deployment Share• Updating the deployment share creates a

custom MDT Windows Pre Installation Environment (WinPE)

• This WinPE is very intelligent• Pre-configured to know who the MDT server is

and the name of the Deployment Share

Quick Note on Using USB Hard Drives• Different BIOS number the USB hard drives

differently• When numbered 0 – they can show up as fixed

drives and you don’t want that• ConfigMgr OSD does not support booting from

USB hard drives

Automate the Clients Experience• When you run the Deployment Wizard• Choose which screens are displayed during

the deployment• Suppress the ones you don’t want anyone

to see or change like:• Product Key• Administrator’s password

• Customize the words displayed on the pages

Linked Deployment Shares (LDS)

Good WAN Links



Linked Deployment Shares (LDS)• LDS allows you to copy a subset (or all if

you choose) of components to another machine

• Even Windows 7 can host a LDS• But, if you host the LDS on a server you

can integrate WDS with it• To create a LDS• Begin on the target computer

MDT Database• Automate what gets installed on a computer

• Original image and re-imaging• How it works:

• When a client begins the Deployment Wizard a script runs: ZTIGather.wsf

• Gathers all kinds of information from the client like:• Universally Unique ID (UUID)• Serial number• Asset tag• MACAddress

• Queries the MDT database for a match• Applies the configured settings

New To MDT 2012

MDT 2012 & ConfigManager• Aligned more closely with Config Manager 2012• Shipping times:

• RTM after Config Manager 2012 ships• Beta 2 – around October• Still need to integrate MDT 2012 into Config Manager 2012

• New Terminology• Advertise = Deploy• Packages can either be optional or mandatory

• Optional = available• Mandatory = required

New Features• New Deployment Wizard• Deploy .vhd images• Supports deploying ThinPC and POSReady

• ThinPC – basic Win7• Citrix or Terminal Services client

• POSReady• Point of Sales – cash registers

• Cross platform deployment• 32 bit WinPE can deploy 32 or 64 bit OSs

More New Features• Diagnosis and Recovery Toolset (DART)

• Allows remote control of target machines• Even in the WinPE phase

• Deployment Workbench gets a new tab• Monitor deployment clients

• Properties of the deployment share are more streamlined• New UDI wizard designer• Image factory – create .wim or .vhd

• Vhd can be deployed via Virtual Machine Manager as templates to create new virtual machines

Unified Extensible Firmware Interface (UEFI)

• Full support of UEFI• Intels replacement for PC BIOS• Offers support for GUID partition tables (GPT)

• MBR partition tables restricted disk partition sizes to a maximum of 2.19 TB

• MBR supports only 4 partitions• 4 primary• 3 primary and 1 extended (break it up into logicals)

• GPT allows a maximum disk and partition size of 9.4 ZB• 1 zettabyte = 1 billion terabytes• Supports upto 128 volumes

512 Byte – 4K Misalignment• Legacy drives support 512-byte physical

sectors • OSs use 4K logical block sizes

• virtual memory pages & file systems like NTFS

4K

Sector Overhead• Data• ID Information

• identify each sector by number and location• a single bit is used to indicate if the sector has been marked defective

• Synchronization Fields• Where do I go to find the next piece of a file

• Error Correcting Code (ECC)• ensure data integrity

• Gaps or spacers• separate sector areas and gives the controller time to process what has been

read before moving on to process more data

What’s The Problem? The Fix• The result is performance is degraded

• 10% – 30%• The fix is for hardware and OSs to both

read at a 4K sector size• 4K sector sizes are not supported for XP• But they are in WinPE 3.0

Windows Deployment Service (WDS)

Windows Deployment Service• WDS replaces Remote Installation Services

(RIS)• Provides both boot and installation images

from the WDS server • Supports .WIM and .VHD technology

Use a Specific WDS Server

Adding a Boot Image• A boot image is a Windows Pre Installation

Environment (WinPE)• The most current will always be best• Windows 7 SP1 Boot.wim can deploy

• Vista SP1 – Windows 7 – Windows 7 SP1• Windows Server 2003 R2, 2008 and 2008 R2

• Use an older WinPE will produce undesired results

Adding an OS Image• Both .wim and .vhd are supported• Adding a .wim

• Right–click Install Images• Add Install Image• Image Groups

• Adding a .vhd• Elevated command prompt• WDSUTIL /Add-Image /ImageFile:\\Server\Share \

Win7.vhd /Server:WDSServer /ImageType:Install /ImageGroup:Windows7 /Filename:"Windows7.vhd"

Add Drivers & Applications• 3rd party drivers only

• No Applications can be deployed from WDS• Only a Thick image containing your

applications

From The Client• Perform a Network Boot

• Sometimes called a Pre Execution Boot Process• OR• PXE Boot

Windows Deployment Services

Multicast Enhancements• Multiple streams of traffic– Optimized rates based on

client connection

• Client Auto Removal– Slower clients can be dropped

to unicast or entirely (only in standard multicast)

• Boot Image Multicast– Windows PE boot

images can use multicast (clients with EFI)
