987.0. "System sizing" by ENUF::GASSMAN () Fri May 03 1991 16:01

    For a computerworld survey on SNMP managers, one of the questions asks
    how many devices can you manage with your system.  What's a good answer
    given a Vaxstation 3100 with 24mb memory and 1.2 gigabyte of disk?

    Bill, do you want to know the theoretical limits or the practical
    loading limits. I am guessing the latter. If so, the answer is define
    what you/they mean by managing. If it is simply interactive monitoring
    you get one answer, if you are doing historical data recording you
    get another answer. I am sure this is not news to you but without
    some guidance, I doubt that anyone is going to volunteer any answers.
    Another issue is that the answer you want is based upon Ultrix and
    with not being in field test just yet, I doubt that there are any
    resources to put together the experiment to get your answer. Also
    How many MIB extensions would you like us to address for the answer.
    That is important because it establishes how big the data dictionary
    is.

987.2Sizing Info is ImportantEISNCG::OLEARYTue May 07 1991 12:2930
    
    The problem of sizing was a big issue with NMCC/DECnet Monitor, and
    really needs to be addressed.  Obviously, there are marketing and
    advertising implications as Bill's request proves.  Bill, how do other
    companies answer that question?  My guess is that they put some
    theoretical value in that *could be true* (through minimal management)
    and *looks attractive*.  
    
    Without effective sizing information how can we figure out:
    
    	. What kind of system (CPU, memory, disk space, etc) to get for 
    	  DECmcc?
    
        . IF more than one MCC licence/director is needed for a customer's
          environment?  It is essential that the sales people know this up
          front so proper expectations can be set.
    
    	. WHEN additional directors/MCC's are needed for a customer's
    	  environment?  This is essential for customers to plan
          appropriately (budgeting, etc).
    
    
    I'm sure there are many other needs for sizing information.  Wally, I
    realize that this kind of stuff is difficult to obtain (and maybe too
    early at this time), but please don't underestimate its importance.
    What can be done to help get it?
    
    Thanks

987.3>1000 is today's answerENUF::GASSMANTue May 07 1991 13:387
    Since they only wanted a number, and not a story - I put down >1000
    depending on configuration - when ultrix and then eventually when
    distributed management comes along - that number should be in the
    10,000 range or even higher.
