1 Windows Server 2012: New Features

2 Administering Servers with Server Manager Using Server Manager, you can: Manage multiple servers from one instance of Server Manager Deploy roles and features to remote servers Generate Windows PowerShell scripts for actions performed in Server Manager Group servers View the status of all servers from a single location Determine whether roles on the network are functioning efficiently

3 Adding and Removing Roles and Features Remotely deploy roles and features Add roles and features to virtual hard disks even if the virtual machine is turned off

4 Using Windows PowerShell in Windows Server 2012 The new PowerShell Integrated Scripting Engine provides: Integrated help – enables you to search for Windows PowerShell cmdlets if you know a few characters in their name. IntelliSense - which suggests values as you type and prompts you for parameter values.

5 Removing and Restoring the Graphical Interface Benefits of Using Server Core  Reduced update requirements.  Reduced hardware footprint. Graphical shell is now a feature. Can be turned off and back on again Server Core Installation Options  Server Core. The standard deployment of Server Core. It is possible to convert to the full version of Windows Server 2012.  Server Core with Management. This works the same as a deployment of Windows Server 2012 with the graphical component, except that the graphical components are not installed.

6 Important New Features New features of AD DS: New deployment methods Simplified administration Virtualized domain controllers Active Directory module for PowerShell Windows PowerShell History Viewer Active Directory Based Activation

7 Active Directory Recycle Bin The Active Directory Recycle Bin: Cannot be disabled once it is enabled Now has a user interface to simplify restoration of objects Is enabled and accessed through the Active Directory Administration Center Cannot restore sub-trees of object in a single operation Requires the forest level be at least Windows Server 2008 R2 Requires Enterprise Admins Increases the size of the Active Directory database Objects are preserved in the recycle bin for a configurable period, which is 180 days by default Deleted objects can be viewed in the Active Directory Administrative Center console Objects can be restored by selecting them and choosing Restore

8 Improvements to Domain Controller Virtualization You can safely clone existing virtual domain controllers by: Creating a DcCloneConfig.xml file and storing it in the AD DS database location. Taking the VDC offline and exporting it. Creating a new virtual machine by importing the exported VDC. DcCloneConfig.xml to AD DS database location Export the VDC Import the VDC

9 Group Managed Service Accounts Group Managed Service Accounts provide: Automatic password and SPN management to multiple servers in a farm A single identity for services running on a farm Group managed service account Farm server1 Farm server2 Farm server3

10 Introduction to Dynamic Access Control Dynamic Access Control provides :  Data classification  Access control to files  Auditing of access to files  Optional RMS protection integration Give users access to file system objects based on their attributes in AD DS and the Classification of the file system object Finance

11 What are Identity, Claims, and Central Access Policy? Identity is information provided from a trusted source about an entity Claims are statements made by AD DS about specific user or computer objects Central Access Policy contains one or more Central Access Policy rules which determine applicability and permissions

12 Overview of How to Implement Dynamic Access Control TaskPurpose Enable support in AD DSTo enable AD DS to apply Dynamic Access Control Create and configure user and device claims To identify attributes that will be used in Dynamic Access Control Create resource property definitionsTo identify resource properties that will be used in conditional expression Classify filesTo automatically set values on properties Create Central Access RulesTo define scope and conditional expressions Create Central Access PolicyTo group Central Access Rules and act as a safety net over resources

13 New Storage Features in Windows Server 2012 Multi-terabyte volumes Data deduplication Storage Spaces and Storage Pools Unified remote management of File and Storage Services in Server Manager. Server Message Block 3.0 iSCSI Target server Resilient System Scale-Out File Server Windows PowerShell cmdlets for File and Storage Services

14 Storage Spaces To create a virtual disk, you need the following: One or more physical disks Storage pool that includes the disks Virtual drives (or storage spaces) that are created with disks from the storage pool Disk drives that are based on virtual drives You can use storage spaces to add physical disks of any type and size to a storage pool and create highly-available virtual disks from it Virtual drives are not virtual hard disks; they should be considered as a drive in Disk Manager Physical Disks Storage Pool Virtual Disk Disk Drive

15 What is SMB 3.0? High Speed SMB Multi-Channel SMB Direct SMB Encryption

16 iSCSI Target The iSCSI initiator: Runs as a service in the operating system Installed by default on Windows 8 and Windows Server 2012; just needs to be started The iSCSI target server: Is available as role service in Windows Server 2012 Provides the following features:  Network/diskless boot  Server application storage  Heterogeneous storage  Lab environments

17 Data Deduplication Data deduplication identifies and removes duplications within data without compromising its integrity or fidelity with the ultimate goal to store more data on less space You should consider using deduplication for the following areas: File Shares Software Deployment Shares VHD Libraries

18 BranchCache Improvements BranchCache caches data from head office to branch office, reducing network bandwidth and improving performance at the branch office BranchCache improvements in Windows Server 2012 include: Performance Performance is improved through chunking improvements and caching starting sooner.

25 Overview of Networking Changes DNSSEC DHCP Data Center Bridging NIC Teaming IIS

26 DNSSEC Improvements New Resource records defined in Windows Server 2012  DNSKEY  DS  RRSIG  NSEC3 Trusted Anchor  In DNS it is the DNSKEY resource record or DS resource record hash of DNSKEY resource record. Clients use these records to build trust chains. Name Resolution Policy Table  Contains rules that control how DNS clients validate responses.

27 DHCP Improvements DHCP name protection can be configured in properties at the IP level or scope level DHCP LimitationsWS 2012 solution Failure of DHCP will result in loss of network connectivity for clients DHCP failover Windows systems can have their DNS name registrations overwritten by non-Microsoft systems bearing the same system name DHCP name protection

28 Data Center Bridging Reserves bandwidth by the type of network traffic Requires DCB-capable NICs Bandwidth Reservation: Live Migration Media Streaming Video Conferencing

29 NIC Improvements NIC Teaming Consistent Device Naming NIC 1

30 IIS 8 Application Initialization Centralized SSL Certificate Support: SSL Scalability and Manageability CPU Throttling: Sand-boxing Sites and Applications Dynamic IP Address Restrictions FTP Logon Attempt Restrictions Multicore Scaling on NUMA Hardware Server Name Indication (SNI): SSL Scalability WebSocket Protocol Support

31 What Is IPAM? IP administration areaDescription Planning Reduces the time and expense of the planning process when changes occur in the network Managing Provides a single point of management and assists in optimizing utilization and capacity planning for DHCP and DNS Tracking Enables tracking and forecasting of IP address utilization Auditing Assists with compliance requirements and provides reporting for forensics and change management IPAM facilitates IP management in organizations with complex networks by enabling administration and monitoring of DHCP and DNS

32 IPAM Functions and Architecture IPAM discovery IPAM address space management Multiserver management and monitoring Operational auditing and IP address tracking IPAM provides four main functions : Distributed Centralized Hybrid You can deploy IPAM in the following topologies:

33 Address Space Management IP address blocks IP address ranges IP addresses IP inventory IP address range groups You can view and manage the IP address space using the following views: DNS and DHCP servers DHCP scopes DNS zone monitoring Server groups You can monitor the IP address space using the following views:

34 Features of VHDX File Format Virtual hard disks can be as large as 64 terabyte File structure minimizes the chance that the disk will become corrupt if the host server experiences a power outage VHDX supports better alignment when deployed to a large sector disk Allows larger block size for dynamic and differencing disks, which provides better performance for these workloads VHDX
