Consideration for Dell EMC PowerScale (Isilon)

The following considerations and limitations are applicable:

Recommend limit for the snapshot of directory is 1024 and the cluster-wide Snapshot limit is 20000.
See: https://www.delltechnologies.com/asset/en-us/products/storage/industry-market/h16857-wp-onefs-best-practices.pdf
Avoid creating snapshot directories that are already referenced by other snapshots. For example, if you create 500 snapshots of /ifs/test_fs1 and 500 snapshots of /ifs/test_fs1/test_fs2, you have created 1000 snapshots of /ifs/test_fs1/test_fs2.
For replication, set the SyncIQ policy for the backup selection as synchronize on the Dell EMC PowerScale (Isilon array).
