Exchange 2007 SP1 and Windows 2008


Now Windows 2008 has been released to manufacturing (RTM), all new implementations of Exchange 2007 SP1 can be designed using Windows 2008 Server (SP1 is a minimum requirement for Windows 2008, a full list of prerequisites can found at http://technet.microsoft.com/en-us/library/bb691354.aspx ).


Windows 2008 new features


 


For a full new and updated list of features in Windows 2008 see the following link http://www.microsoft.com/windowsserver2008/en/us/compare-features.aspx


Topology


 


If you are running Windows 2008 Read-only DC’s (RODC) or Read-only Global Catalog servers (ROGC), be aware that no version of Exchange supports these new types of server roles and Exchange requires a writeable server. However Exchange 2003 SP2 and Exchange 2007 are supported in a Windows 2008 AD environment.


Windows Upgrades


 


In place upgrades cannot be performed when the server is running Exchange, so in order to run Windows 2008 and Exchange 2007 SP1 you will need to build a fresh server. Official guidance for migrating from Exchange 2007 running on Windows 2003 to Exchange 2007 running on Windows 2008 can be found at http://technet.microsoft.com/en-gb/library/cc296562.aspx


Exchange 2007 Sp1 new features when running Windows 2008


 


These are only a few of the new and improved features of running Exchange 2007 SP1 on Windows 2008


 


·         Faster log shipping – Windows 2008 includes SMB v2, which increases the throughput performance by around 30-40%


·         Support for multi-subnet failover cluster – Running a Windows 2008 failover cluster with Exchange 2007 SP1 includes support for geographically dispersed cluster for failover across 2 subnets


·         Improvements for Client Access Servers (CAS) – Windows 2008 removes RPC Proxy service TCP connection limits. Previous versions of Windows had a limit of 65,535 connections per server, Windows 2008 now supports 65,535 connections per IP address


·         Easier deployment – Windows 2008 includes Windows PowerShell


·         Support of IPv6 – IP addresses can be entered using IPv4 or IPv6 (the default installation supports both versions)
