965.0. "Connectors and Sizing" by ZPOVC::YINGYONG () Mon Mar 31 1997 08:28

    There are info from the Performance group on the Exchange sizing on
    AlphaServer.  What about servers that have MS mail, SMTP, and site
    connectors ?  The link speed for site connectors are 64K bps or lower.
    
    How would these connectors affect the sizing of Exchange servers ?

    Any connector or connectors would decrease the number of users from
    the single server numbers by at least 30%.  This is due to the increase
    in mail processing.  Based on the 80/20 rule where 20% of recipients
    are off node. 
    
    See our web site (yesmom.zko.dec.coom) for the latest .PPT presentation
    for more info on connectors.
    
    It is also our recomendaton that if you have multiple connectors on
    your systems a Bridgehead server be used.  Then you will only have
    1 active connector on each system.  A second connector with a higher
    cost should be used to a backup bridgehead system.
