Is there a way to caculate srdf r1->r2 daily replicacate data capacity? from SPA(symmetrix performance analyzer) or ECC I can get the min/max/average bandwidth,but I could not find anywhere can tell you how much data replicated daily/weekly/monthly.

HI,
From SPA, you can only tell how much mb/sec you are tranferring in a day/week/month (its average). There is no metric in SPA which can give you the exact figure of the amount of data transferred across the arrays. I think there are few tools which collect this information from the fabric.
regards,
Saurabh

It is very important that the SAV pool be able to keep up with the write rate to the sorce devices at the time the snap is activated. At that time the SAV pool will see 100% writes at the rate at which the source devices are being written to.
This is why RAID1 is best for the SAV pool, and the best configuration is a little bit of SAV capacity on every spinning disk of a given speed in the system. Another important point is every disk should have the same SAV capacity. If one disk has twice as many SAV devices, it will received twice the load from the snap.
