The OpsMgr 2007 R2 Sizing Helper is an interactive document designed to assist you with planning & sizing deployments of Operations Manager 2007 R2. It helps you plan the correct amount of infrastructure needed for a new OpsMgr R2 deployment, removing the uncertainties in making IT hardware purchases and optimizes cost. A typical recommendation will include minimum hardware specification for each server role, topology diagram and storage requirement.

  • Awesome sheet guys, this will help a lot, congrats! I'm happy to one server topology here, and in the next version of this XLS you can talk about suggested monitored network devices number too, please.


  • How does clustering for redundancy fit into this guidance?

  • The deployment guide is the right resource that provides clustering guidance.

    If you want to cluster a RMS, then each physical node in the cluster should have the same min h/w spec for the RMS role as specified in the sizing helper for a given scenario.

  • Very interesting, and certainly one of the nicest looking sizing spreadsheets I've seen.  A couple of questions though,

    1. What kind of assumptions are made as to the monitoring load. In other words is this assuming a base Windows, or is it factoring in monitoring Exchange, SQL, etc.

    2. I don't see any reference to ACS, is that in here as well?

  • Hey bob - long time no see!

    The assumptions behind the monitoring load is constructed from real customer data with key monitoring work load such as AD, Exchange, SQL, IIS, base OS & etc... (data are gathered from the larger enterprise customers - so the model tends to be more conservative & recommends numbers a little bit on the high end)

    The key factors that influence ACS and the resulting topology is a bit different from the core OpsMgr deployment - so we didn't include ACS to prevent the sizing helper from getting over complicated...

    You can still find ACS sizing guidance in the OpsMgr Design guide.
