  • 1.  Maximum device limit in ca spectrum 9.4

    Posted Nov 24, 2015 06:02 AM

    Hi

     

    Can some one tell me what is the maximum limit of devices or elements we can discover in CA Spectrum 9.4. Because we have some issues in our CA spectrum (Devices are discovering with "No Name" or it will be in Initial status with blue colour for 2 days, and Online scheduled back up is taking more than expected time like 2 to 4 hours, And device down alerts are not clearing though they starts pinging or polling). CA customer support guy told us because we have around 220000 elements that is around 4000 devices. But we can not find in any of the documents where its written about the device limits. Can some please help on this.

     

    Regards

    CA statements on supported number of devices for 9.x is 2000 per landscape. That's a conservative number, as they are thinking of monitoring everything SPECTRUM can do on that server. At least that the number I've heard many times. From experience and depending on what you're monitoring, it can handle up to 4000 devices. That is if your not monitoring QoS, MPLS or other services on all devices. I have installations that are working fine with 4000 devices.

     

    SPECTRUM 10 was built to handle 10.000 devices and 1.000.000 models on a single SpectroSERVER. That's the new number.

    There is no real hard limit on the number of device models or total number of models that can be managed by a single 9.4 SpectroSERVER. The rule of thumb is between 2000 and 2500 managed device models but again, that is not a hard limit.

     

    There are two main factors:

     

    1. The hardware (amount of memory, speed of processor, number of processors disk speed, and bus speed)
    2. What you are doing with your Spectrum database. How many integrations, number of Global Collections, number of SpectroWatches, number of users, number of OneClick systems, polling intervals, number of traps per second processed, etc

     

    I can take a 2000 device model database and load it on a high end Linux or Solaris system and bring it to its knees. I can take that same database and load it on my Windows laptop and make it run without any issues.

     

    If you are having performance issues, please open a case with Spectrum support so a performance analysis can be done to determine where performance bottle neck is.
