Overview
Windows 8 OEMs
Server 2012
Server Management
Active Directory Enhancements
Storage
Virtualization
• The Windows 8 interface has been “reimagined”
– Tile based “live” apps.
• 2 UI’s
– Tile based interface for supported apps
– Desktop UI for traditional x86 apps
• Interface was designed to be “seamless” when
transitioning between Windows devices
– Less learning curve between desktop down to
mobile device
• Most management tools have been server
focused
• Driving force behind 2012 is to centralize
server infrastructure management
– All servers are centrally managed on the
Dashboard
• Windows 8 and Server 2012 share the same
code base
• Microsoft has identified four key areas of
advancement:
– Virtualization
– Centralized management
– Modern workforce
– New app platform
• Windows 8 RT—designed for mobility. Only
runs built-in apps or apps downloaded from
Windows Store
• Windows 8—consumer based version. Does
can not be joined to domain
• Windows 8 Pro—Domain joinable, BitLocker,
Hyper-V
• Windows 8 Enterprise--
• Features and system requirements:

• System Requirements
Minimum HD
32GB
Minimum Processor
1.4 Ghz
Minimum RAM
512MB
Peripheral Int. Devices
DVD-ROM, Internet connection,
Keyboard, Mouse, SVGA Monitor
• PowerShell
– No one really uses it to it’s capacity
– Server 2012 provides expandable pane to reveal
underlying PowerShell commands to accomplish
certain tasks.
• Copy/Paste code to use later for automation scripts
– Better command “autocomplete”
– More command-lets
• 200 in 2008 R2
• 2300 in Windows Server 2012
• Server ManagerReimagined
• Three goals in mind
– Active Directory (AD) needs to have virtualization
that simply works
– Must be simple to deploy
– Must be simple to manage
• Virtualization that works
– Problems caused by AD
• Virtual Image restoration
– System thinks it from an earlier time (Time Traveler)
– Update Sequence Numbers are used to keep track of
replication of data between DCs.
– Replication issues can occur (time stamps all jacked up)
– Can cause an issue called USN rollback

• Virtualization that works
– Server 2012 is “virtualization safe”
– A virtual DC is able to detect when snapshots are
applied or a virtual DC has been copied.
• Uses VM generation ID (gen ID)
• Works with Hyper-V and are currently working with
other vendors to make sure it works in those
environments.
• Domain Controller Cloning
– Deployment made easier by the gen ID technology
• Upgrades and DCPromo Made Simple
– Upgrade domains and forest entirely from Server
Manager
• No ADPREP/FORESTPREP/DOMAINPREP
– DCPromo was made easier with a troubleshooting
feature built in.
• Administration Improvements
– Any administrative tasks in AD can be
accomplished using PowerShell
• 2002300 cmdlets!!!!
– Less building of scripts. Probably a cmdlet to do what you
want.
• AD Recyle Bin has been GUI-Ized
• ADAC has a hidden PowerShell panel that you can view
to see what are the equivalent PowerShell commands
• Active Directory Product Activatation
– Uses LDAP instead of RPC
– Still requires a KMS server
• Three primary improvements
– Storage pools and spaces
– CHKDSK
• Storage pools and spaces
– Storage pools are units of storage aggregation that
provide administration and isolation
– Storage spaces are give virtual disks performance,
resiliency, and simplified storage provisioning
– Use storage spaces to consolidate individual
storage devices rather than allocating logical drive
mappings
• CHKDSK
– Two phases
• Online scan and corruption logging which checks for
defects behind the scenes
• Offline fixing phase that only corrects defects in drive
data
– Results in an exponentially faster CHKDSK process
• Hyper –V 3.0 Scalability
– Supports up to 160 logical processors
– 2 TB of RAM
– Guests can support up to 32 VCPU’s and 512GB
Ram per VM
– More cost effective alternative to VMWare
• VMWare private cloud comparable solutions can cost 516 times more than a Microsoft solution over 1-3 years.
• Microsoft licenses on a per processor basis which
makes the solutions more scalable and predictable
