The ShareMaximum property defines the maximum number of I/O Drivers that are grouped into a shared I/O Server. This property is only used when the ShareServer property is enabled. Example:

' This driver will not be shared
ShareServer = False
ShareMaximum = <any value>
' All drivers are grouped into the same IOServer
' Does not define a limit
ShareServer = True
ShareMaximum = 0
' Groups every 5 drivers into an IOServer
ShareServer = True
ShareMaximum = 5
