Great News From Walldorf – SAP Microsoft Platforms Group Officially Announced Windows Server 2012 General Availability and Support For SAP NetWeaver

SAP Microsoft Platforms group finally released SAP NetWeaver on Windows Server 2012!

Current supported SAP NetWeaver (ABAP, Java, ABAP+Java) releases are:

  • SAP SAP NetWeaver 7.0x based
  • SAP NetWeaver 7.30 and 7.31

Different databases are already supported, for updated list please check SAP Product Availability Matrix (PAM)

Currently supported SAP standalone component is SAP liveCache.

You can run your SAP NetWeaver on Windows 2012 both in physical and virtual environment.

In virtual environment you can run Windows Server 2012 guest OS on these hypervisors:

  • Windows Server 2012 Hyper-V
  • Windows Server 2008 R2 Hyper-V
    (due to scalability limitation of  Windows Server 2008 R2 Hyper-V  it is highly recommended to use Windows Server 2012 Hyper-V )
  • VMware vSphere 5.1
  • VMware vSphere 5.0 (min U1, U2)

High Availability with Microsoft Windows Server Failover Cluster is off course fully supported and fully integrated in SAP sapinst installation software!

For more information on SAP NetWeaver HA in physical and virtual environment you can check in this White Paper: SAP NetWeaver High Availability and Business Continuity in Virtual Environments with VMware and Hyper-V on Microsoft Windows

Windows Server 2012 brought huge improvements in compare to Windows Server 2008 R2, in the area of scalability, server virtualization, business continuity, high availability, networking and storage.

Many thanks to SAP Microsoft Platforms group for making this happen, specially to Jason Kafka for driving overall Windows Server 2012 part and Claudia Baur for driving virtualization part.

A new optimized high performance SAP kernel on Windows speeds up SAP applications performance up to 20 % !

Recently SAP development department called Microsoft Platforms published a new optimized high performance SAP 721 EXT kernel on Windows, which is powering different applications running on top of SAP NetWeaver stack (ABAP, Java and ABAP+Java).

The new SAP kernel is significantly speeds up the performance of the SAP applications up to 20 % !

721 EXT kernel is fully downward-compatible kernel and can be used instead of the 700, 701, 710, 711 and 720 kernel, including the EXT versions, which means you can use it for your SAP Business Suite applications.

You can run this high performance kernel on all supported Windows OS both in physical as well as virtual environment.

All this is achieved by introducing a new compilation method called Performance Guided Optimization (PGO) into the product build process on Windows. More information on PGO you can check in this blog: Profile Guided Optimization (PGO) drives next generation SAP NetWeaver Performance

The whole project was successfully driven and executed by two experts from SAP and Microsoft working in Microsoft Platforms group, namely Jason Kafka ( and Mike Gusev (
