Hi Gurus ,

I am having AIX servers for which DR needs to be settle down soon. Can you guide how to calculate the bandwidth sizing for Storage based replication.What factor i need to consider or calculate for Bandwidth sizing.

In solaris we run crontab scheduled iostat for every 15 mins & get the data as average write / 15mins. How to accomodate the same in AIX.

Kindly help.
