Hi Matthew,
That document does not explain what do they do to keep exchange database
synchronized in an active/active configuration.
Do you know if in active/active "some mechanism" replicates "all the time"
data from NodeA to NodeB, so in the vent of NodeA going offline then NodeB
takes place? and also I do not understand why do they alert on number of
storage per server..is it that NodeB and NodeA can have diffente number of
staorages? should not they be two identical servers/databases/paths.
thx
