32 PS Series Asynchronous Replication Best Practices and Sizing Guide | BP1012
7.5.1 Primary group space considerations
The PrimaryGroup is a group with two PS6210 members and two pools (in this example only the volumes in
the hybrid pool will be used).
From a best practice perspective, sizing to the volume total reported size is a way to ensure that secondary
group is sized to accommodate the volume potential growth. The particular needs of the environment may
override this general rule, however the overall growth potential should still be considered.

Example of using the reported size instead of the in-use space.
The total reported size is 840 GB, which includes two volumes each with 420 GB: repl-vol1 (420 GB) and
repl-vol2 (420 GB).
The total space in use is also important to understand, since this will be the total amount of data initially
replicated to the secondary group. In use for this example includes two volumes each around 400 GB. The
first replication will synchronize 800 GB (repl-vol1 in use is ~400 GB and repl-vol2 in use is ~400 GB).
