Of course, the above is for illustration only. If your Company policy does not dictate geographically

Fan IN
When we talk about FAN IN, we are considering the number of replication Source Appliances that are
supported.
HP D2D250x Series
Each HP D2D 2500 Target Appliance can support up to 6 Source Appliances. Each library on the
Target Appliance must be uniquely mapped to one library on a Source Appliance. For example:
a company has 6 remote sites and a Data Center. Four of the remote sites have one library each
62
