Key Areas of Focus of WindowsKey Areas of Focus of Windows20082008

• Improvements in Server Security• New Terminal Services capabilities• Network Access Protection (NAP)• Improvements in Networking• Enhancements to Directory Services• New Deployment Roles• Improved Interoperability with Unix• Reliability and Performance Improvements• New Application Server• Management improvements


Windows 2008 “Under the Hood”


Dynamic PartitioningDynamic Partitioning

• In the past, hardware upgrades and maintenance have required a shutdown, resulting in downtime

• Windows Server 2008 reduces the need for downtime by supporting these hardware configuration changes without a reboot

• Hot plug PCI Express• Hot replace of memory• Hot add and replace of processors


SMB2SMB2• SMB is the original Windows remote file

system protocol– Can’t adapt to new NTFS features– Not designed for today’s large data sizes

• SMB2 introduced in Windows Vista and Windows Server 2008– Supports NTFS client-side symbolic links– Operations can be batched to minimize client/server

round trips– Support for arbitrary buffer sizes for more efficient

copies result in 30-40x throughput improvement


Clean Service ShutdownClean Service Shutdown• In the past, services had no way to extend the time

allowed for shutdown– After a fixed timeout (default 20 seconds), SCM was killed

and system halted (while services were running)– This was a problem for services that needed to flush data

• In Windows Server 2008, services can request preshutdown notification– Can take as long as they want to shut down as long as they

are responsive– If the service stops responding the system gives up on it after

3 minutes– After pre-shutdown services stop, the system performs

Windows XP-style shutdown for other services


Windows Server 2008 is IPv6-Windows Server 2008 is IPv6-ReadyReady

• As with Windows Vista, IPv6 is on by default (and can be centrally managed)

• IPv6 can be used on IPv4 networks using numerous built-in transition technologies:– Intra-Site Automatic Tunnel Addressing Protocol

(ISATAP)– Teredo (NAT traversal for IPv6 over IPv4 networks)

• Example of current IPv6 applications:– Windows Meeting Space enables shared views,

text messaging, presentations, file sharing– Remote assistance possible through NATs by using

IPv6


HypervisorHypervisor

•Windows Server 2008 is the basis for Microsoft’s new virtualization offering (codename “Viridian”)•Hypervisor to control low level access to system resources•Root partition implements device support using Server Core

•Different than VMWare ESX where hypervisor implements


Examples of Windows Server 2008 Roles:Examples of Windows Server 2008 Roles: – Active Directory Certificate Services– Active Directory Domain Services– Active Directory Federation Services– Active Directory Lightweight Directory Services– Application Server– DHCP Server– DNS Server– Fax Server– File Services– Network Policy and Access Services– Print Services– Terminal Services– Web Server– Windows Deployment Services– Windows Server Virtualization– Windows Server Update Services 3.0 Service Pack 1 (New!)


• Revolutionary interactive shell and scripting language– Based on .NET

– New set of built-in tools (~130)

– New language to take advantage of .NET

– Can continue to use current tools

– Can continue to use current instrumentation (COM, ADSI, WMI, ADO, XML, Text, …)


• Do I need to learn .NET before I can use PowerShell?– No - you can continue to use existing tools

• Do I need to rewrite all my existing tools?– No - existing tools will run just fine

• Do I need to learn the new language?– No - You can easily run existing commands

without modification – Many Linux commands work… try them…


Windows Server 2008 Installation Types:

• Full Server Installation• Server Core

– Stripped down version without GUI
