  • 1.  Spectrum 10: Performance experience regarding number of devices/models

    Posted Jul 09, 2015 05:39 AM

    Hello

     

    According to the release notes of Spectrum 10 we see huge improvements regarding number of devices/models per server (due to 64-bit support).

     

    Has anyone already tested this new scalability and can share their findings/results?

     

     

    Kind regards,

      Leo Bär

    Hi Leo_Baer,

     

    Sharing one of the thread on Spectrum ideas community: Speed up the  model activation process in Spectrum.

     

    Community members talking about improvement in model activation with Spectrum 10.0.

     

    Thanks,

    Nagesh

    Hello Leo,

     

    overall the CA Spectrum R10 64bit improvements will help to allow more "concurrent threading" for the SpectroSERVER - and to load more data "into the stack". But this is a valid improvement in case of a "static" network and without a detailed view to the modeling. Modeling is one factor which can affect the internal CA Spectrum logic - like the Fault-Isolation and the RootCauseAnalysis.

     

    Therefore - knowing the current CA Spectrum runtime - i.e. on R9.3 or R9.4 flavours - needs to be reviewed. Main point to start is the SSPerformance application model which is available per single Landscape /SpectroSERVER. Have a look to the SSPerformance application model - find these via Locater Search - check for the Component Details - Performance tab -- and here select (i.e. for 6 hours):

     

    SS_Idle_Time -- 100% indicates any new thread can immediatelly start / 0% means - no more thread right now (hanging thread / single thread-condition)

    SS_Timer_Latency  -- which is delay in seconds

    SS_Polling_Latency -- which is delay in seconds

     

    In case of temporary high workload condition the "SS_Idle_Time" may show for a 1 minute 0%_condition - which affects anything at SpectroSERVER level - then you may find polling and timer latencies. Having a high loaded SpectroSERVER may require to re-poll many devices - much more then before at R9.4 workload. So - in general there is no common rule that we can suggest to double the number of devices - or more for a SpectroSERVER with Release 10 (versa current R9.3/R9.4). Knowing the current CA Spectrum usage and workload (i.e also the events per second / alarms per second / average) is important.

     

    Next then is - to have on top of a most_current_hardware SpectroSERVER - running a OC-server with also high performance platform being able to process and propagate the high workload.

    In general it is true - the R10 SpectroSERVER allows much higher model load - we tested with 800k models and is runs with good performance. But again - please honor the fact of this 3 tier application design and it is important to have SpectroSERVER and OC-server running on modern platform. Cheers, Joerg
