Internet Information Services (IIS) have some interesting new features in Windows Server 2008 R2, which justifies the new version number, i.e. IIS 7.5. Most noteworthy  is that you can now run ASP.Net applications on Server Core. Of course, it will reduce security if you install .NET on Server Core, but IIS without .NET doesn’t make much sense either. The performance-related improvements are not very exciting in my opinion. However, support for 256 logical processor cores makes Windows an interesting server OS for cloud computing.

Internet Information Services 7.5 (IIS) ^

  • PowerShell provider for IIS 7 has more than 50 new cmdlets

  • Integrated extensions: new kind of extensions that appear to be an integral part of IIS

Scalability ^

  • Support for up to 256 logical processor cores (Windows Server 2008 supports 64 logical cores)
  • Hyper-V virtual machines support up to 32 logical cores (Hyper-V 1.0 supports 4 processor cores)
  • IP Stickiness: Configure the time period (weeks or months) that a connection state to a specific cluster node persists

Storage ^

  • Performance: Reduced processor utilization for “wire speed” transmissions; improved input/output process (NTIO); up to 32 paths to a storage device are supported; improved iSCSI client; storage subsystem allows hardware vendors to optimize their storage mini-driver; better Chkdsk performance
  • Availability: Failover to alternative path; configuration snapshots (ability to restore a previous configuration)
  • Manageability: Automated deployment of configuration settings using Unattend.xml; improved monitoring (new performance counters, logging for storage drivers, health-based monitoring)

    is possible upgrade Windows Server 2008 R0 to Windows Server 2008 R2 ?


  2. Richard 12 years ago

    Yes, you can upgrade from 2008 to 2008 R2


  3. Steven A. Ealy 12 years ago

    You can only upgrade from server 2008 if it using a 64-bit OS. You cannot upgrade from 32-bit server 2008 to 64-bit only server 2008 r2.

    IIS7.5 does not include the IIS Reports Feature.
