Hardware upgrade Recommendations

Hey guys,

We are looking to upgrade our primary poller and SQL server, I am looking for hardware sizing guidelines. We have a large network that is currently pushing our hardware close to its limits and there doesn't seem to be any documentation provided which will provide a definitive guide to what hardware could handle what size network. Any body know where I could find this info? Cheers!!

  • This part of the documentation should provide some helpful information.  I'll check with the PM to see if they can elaborate more based on the size of your network.

  • Hi there,

    Could you tell us how many elements are you monitoring, how many pollers you have etc? Also, are you using Universal Device Pollers, receiving Traps and Syslogs? What type of hardware are you using now?

  • Hi Deltona,

    Thanks for getting back. Yes we are using Universal Device Poller and we are receiving Traps and Syslogs. We are currently monitoring 19,000 elements and want to upgrade to allow for 30,000. We have 2 pollers, a primary and a secondary, our primary poller is running on a virtual machine and our secondary is running on a stand alone machine. We are happy with the performance of the secondary poller but we are looking to put the primary poller on a machine of its own. Our SQL server is running on its own machine with a total disk space size of 136G. Processor =  2 x Intel Xeon 3Ghz with 3.25GB of RAM. Size of the Net Perf Mon database on the SQL Server is 30GB. The machine on which the primary poller is running has Intel Xeon 3Ghz with 3.25GB of RAM.

    Thanks!

  • noobes,


    Have a look here.

    Do you have hardware specifications for the additional polling engine?

  • Hi Noobes

    With 19000 elements on the way to 30000 will need server no. 3

    Solarwinds recomend  up to 12,000 element per engine.

    If you run pollers on VM that just fine if they get the CPU and RAM they need to work 2X 64bit Intel 2Ghz +4-6GB RAM

    SQL run 2 or 4X64bit  2.8Ghz min 16GB RAM in your case.

    To keep Solarwinds run fast

    1.Hardware server SQL with alot of RAM and 15k disk.

    2.Keep the engine under 10,000 if you can.

    3.If you introduce netflow to that setup you will probebly will talk to a DBA.


  • Hardware spec for secondary polling engine = 6 core AMD Opteron Processor 8435 2.6 Ghz, 2GB of RAM

  • Hi Danielle,

    My thread regarding planning a hardware upgrade was getting some response, but has since been idle. I was wondering if you could recommend what more I could do to get some solid hardware recommendations? I've provided some more information on the thread, is there anything more I should provide? Is there anyone in the Solarwinds team I could contact to get some really solid recommendations? !Thanks

  • I try more than ones to push that to  PM.

    NPM customer’s networks verite in so many ways that

    A full deployment guide will be benefit to Solarwinds and the customers.

  • Hi noobes,

    as Deltona has mentioned above. It mainly depends on what you need to monitor (interfaces, routers, switches, wireless, netflow?) in order to make a good recommendation. Polling engines has so many variables to work with (size of SNMP requests/responses - post processing) so there is no linear ratio regarding used HW and polling performance.

    If you can put here specific details we can get accurate estimates and I can validate with QA if they tested similar configuration.

    In general. SQL is almost always the bottleneck and IO is a key. SJA wrote that 15K drives are recommended which I agree with and RAID should be used to. If there is a really heavy load, you may consider SSD drives too.

    Polling engines usually consumes CPU and memory. they are written for a multiple cores so 6 core or 8 core processor may handle more than 12K elements per single poller.

    ping us with more details.

    thanks,

    Michal
