1 Week #1 Objectives Review clients, servers, and Windows network models Differentiate among the editions of Server 2008 Discuss the new Windows Server 2008 technologies Review Server roles and features in Server 2008 Navigate the Windows Server 2008 interface Install Windows Server 2008 Fundamental of Load Balance and Virtualization

2 Clients, Servers, and Windows Network Models Workgroup –Network of computers that allow each other access to their files, printers, or Internet connection By default, all Windows Server 2008 computers are placed in a workgroup named WORKGROUP

3 Domain Model with Active Directory Domain –Single security database for all users and computes Active Directory Domain Services (AD DS) –Runs the domain security database Domain controllers (DCs) –Servers that hosts domain security database Domain Name System (DNS) –TCP/IP-based standard for resolving computer names with IP addresses

4 Domain Model with Active Directory (continued) Group Policy –Specific configurations for users and computers Forest –A network of domains related to each other by trusts –More than one domain trees Transitive trusts –Trusts within an Active Directory Forest –Automatically created when domains are created

5 Windows Server 2008 Editions General editions of Windows Server 2008 –Enterprise, Datacenter, and Standard –Editions designed for special-purpose server applications Web Server  Can not be DHCP, DNS or File Server HPC Server  For High Performance Computing Apps Itanium Editions –Standard, Enterprise, and Datacenter editions –Available for servers using Intel Itanium Processors –Itanium processors: Different 64-bit architecture

New Technologies in Server 2008 –Improved installation process: Minimal users inputs –Hyper-V: Virtualization –Server Core: Good for Web server Strip-down installation. Minimum Server roles Reduce attack surface –TCP/IP improvements: Full support of IPv6 –Network Access Protection –Server Manager –Windows Remote Management –PowerShell –Group Policy Management Console (instead of editing Group Policy directly from AD Users & Computers) 6

7 New Roles in Server 2008 Server role –Defines the specific task that a server is responsible Roles can be organized into three groups –Active Directory (AD DS, AD CS, AD RMS, AD FS) –Infrastructure Print Services File Services Terminal Services, Fax Services, Hyper-V, UDDI Services, Web Server (IIS 7), Windows Deployment Services –Network roles DHCP DNS NPAS for RRAS and NAP

New Features Feature –Each Server Role has features/job responsibilities related to the roles Features available in Server 2008 –.NET 3.0 Framework –Windows Desktop Experience –Network Load Balancing –Group Policy Management –Remote Server Administration Tools –Windows PowerShell –Windows Server Backup Features 8

Roles and Features Management Server Manager console and Server Manager command-line utility Major areas of information within Server Manager –Server Summary –Roles –Features –Diagnostics –Configuration –Storage 9

Windows Server 2008 User Interface New or improved features in Windows Server 2008 –Start menu: Use the Start Search text box –Network and Sharing Center –Help and Support –Windows Desktop Experience: Like Vista 10

12 Server 2008 Deployment Tools Windows Deployment Services (Replace RIS in W2K3) Multicast Trivial File Transfer Protocol

13 Unattended Install with Answer File Download and run Windows Automated Installation Kit (AIK) to start System Image Manager Windows System Image Manager to create answer file setup.exe /unattend: drive:\answer_file or use with WDS Allows you to configure and deploy –Windows Vista –Windows Vista Service Pack 1 (SP1) –Windows Server 2008

14 ImageX Command-line tool to –Capture, modify, and apply file-based disk images for rapid deployment Can capture an entire disk partition or a specific folder

15 Sysprep Prepares an installation of Windows for imaging and deployment by –Modifying a system to create a new SID and other unique information the next time it starts Removes user and computer-specific information that should not be transferred to new images Generalization –Removing unique characteristics of an installation before creating an image Out-of-Box Experience –Removes all the SIDs, unique characteristics, and applications from an operating system Audit Mode –Allows you to apply additional application and driver modifications to a specific image

16 Windows Recovery Environment A new recovery environment built into Server 2008 A complete diagnostic and recovery solution A platform for building your own recovery solutions

17 Network Load Balancing Cluster Available on all versions of Windows Server 2008 Two or more servers form a cluster. One cluster has one single virtual IP address & virtual MAC address Each server is an NLB node. All nodes are on the same subnet Data Storage Location: –On each node: For static data. Frequent data synchronization. Inconsistent data due to synchronization lag time –At a common location, outside of the cluster For Dynamic data Always consistent Server Manager  Add Features  Select NLB feature –Add Network Load Balancing Manager tool to the Administrative Tools –Use Network Load Balancing Manager to create & configure a cluster

18 NLB Cluster Parameters ParameterDescription IP Configuration Virtual IP Address Set on all Nodes in the cluster Map to FQDN specified for the Cluster Network Address Virtual MAC Address Operation Mode Multicast: ─Virtual Cluster IP address is a Multicast address ─Single network card in each node Unicast: ─Two network cards in each node:  one for within cluster internal communication  one for Client-Cluster communication

19 NLB Port Rules Granularly control how cluster handles communication by port number Each port can set Filtering mode: –Multiple hosts: load balanced –Single host: one particular host responds particular port –Disabled: Block that port Affinity: –None: different cluster node can handle multiple connection from the same client IP address –Single: same cluster node handles multiple requests from the same client IP address

20 Failover Cluster Active/Passive Failover Cluster –Two nodes: one active and one passive –When active node fails, applications & services fail over to passive node Active/Active Failover Cluster: –All nodes active. One node fails, other nodes pick up load

21 Server Virtualization Available on 64 bits of Windows Server 2008 Hyper-V is a Server Role Windows Hypervisor is installed when Hyper-V Server Role is installed. Hyper-V Supports: –Multiple OS Types: Windows, Linux and other –SMP (Symmetric Multi-Processors): up to 4 –Network Load Balancing –Hardware Sharing –Virtual Machine Snapshot –Quick Migration: VM migrates from one host to another System Center Virtual Machine Manager –Manage Virtual Machines and VM components such as scripts, templates, iso images, etc. –Monitor workloads on physical server
