1 Sneak Preview to Windows 2008

2 Key Areas of Focus of Windows 2008 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

3 Windows 2008 “Under the Hood”

4 Dynamic Partitioning Dynamic 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

5 SMB2 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

6 Clean 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

7 Windows Server 2008 is IPv6- Ready 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

8 Hypervisor 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

34 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, …)

35 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…

36 Some good starters –Get-Help –Get-Command | more –Get-Command | sort-object noun | format- table -group noun –Get-Alias | more –Get-Help stop-service -detailed | more Commands are built with logic Verb-noun
