1 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 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 3 Domain Model with Active Directory Domain –Group of users and computers managed by the same security database Active Directory Domain Services (AD DS) –Technology that 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 4 Domain Model with Active Directory (continued) Group Policy –A way to set up specific configurations for users and computers within an Active Directory domain Forest –A network of domains related to each other by relationships known as trusts Transitive trusts –Trusts between Active Directory domains in a tree are created automatically when you create domains

5 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

6 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 7 New Roles in Server 2008 Server role –Defines the specific task that a server is responsible for performing Roles can be organized into three groups –Active Directory –Infrastructure –Network roles

8 8 Active Directory Roles Windows Server 2008 includes five Active Directory roles –Active Directory Certificate Services –Active Directory Domain Services –Active Directory Federation Services –Active Directory Lightweight Directory Services –Active Directory Rights Management Services

9 9 Network Roles DHCP –Network standard protocol used to dynamically allocate and track IP addresses for clients on a network DNS –Main goal is to match a domain name to an IP address based on a client query for information Network Policy and Access Services (NPAS) –Allows you to implement Network Policy Server Routing and Remote Access Service Health Registration Authority Host Credential Authorization Protocol

10 10 Infrastructure Roles Active Directory roles that can be installed in Server 2008 –Terminal Services –Fax Services –Print Services –File Services –Hyper-V –UDDI Services –Web Server (IIS 7) –Windows Deployment Services

11 New Features Feature –Similar to a job responsibility performed by a specific role 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 11

12 Roles and Features Management Server Manager console and Server Manager command-line utility –Used to manage roles and features Major areas of information within Server Manager –Server Summary –Roles –Features –Diagnostics –Configuration –Storage 12

13 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 13

14 14

15 15 Server 2008 Deployment Tools Windows Server 2008 includes improvements to the following tools and technologies –Windows Deployment Services (Replace RIS in W2K3) –Multicast –Trivial File Transfer Protocol

16 16 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

17 17 ImageX Command-line tool that organizations can use to –Capture, modify, and apply file-based disk images for rapid deployment Can capture an entire disk partition or a specific folder

18 18 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

19 19 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

20 20 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

21 21 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

22 22 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

23 23 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 Microsoft Share None Model –NO two nodes can access the same data at any given time Shared Storage –All nodes can access the same data when the other node fails

24 24 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
