This is the first publication starting a series of blogs about High Availability of SAP NetWeaver in
virtualized environments running on Windows Server 2012 Hyper-V.


Part 1 gives an introduction and a brief overview (see attached document):

- Introduction
- Windows Server 2012 Hyper-V
- Basic WS2012 Hyper-V HA Scenarios

  1. Partial       : virtualizing application servers / dialog instances only and keeping the database
                         as well as message server and ERS on bare-metal. This is the easiest way to start
                         with virtualization in a SAP landscape. No specific HA configuration is needed for
                         application servers / dialog instances. It’s handled by redundancy. One just has to
                         make sure that there are enough of them running on different physical servers.

   2. Low          : rely on storage only (e.g. RAID ) / backup
   3. Medium    : accept downtime due to HA only on host level
   4. High         : HA on host level + application level inside VMs
   5. Ultra         : HA across data centers or fire safety zones
   6. Ultra+       : business continuity -> adding disaster recovery in 3rd remote DC

More blogs with technical implementation details regarding specific HA scenarios will follow in the future.

    When is the next part coming out?

  • Hi,

    unfortunately this will take a little bit. I am in contact with hardware vendors to discuss this. To provide high quality information it's necessary to try things out at least in a lab environment before talking about the topic. Right now I have e.g. no access to a metro cluster spanning two data centers.

    There are already articles out there describing WS2012 Hyper-V like these three examples :

    But these articles are not SAP specific. I am working on it.


    Best Regards


  • Very good article

  • Excellent timing as we are just about ready to embark on such a project on VMWare! Hopefully your work will translate to VMWare as well. Thanks!
