[gpfsug-discuss] naive question about rsync: run it on a client or on NSD server?

[Giovanni Bracco]

We must replicate about 100 TB data between two filesystems supported by 
two different storages (DDN9900 and DDN7990) both connected to the same 
NSD servers (6 of them) and we plan to use rsync.

Non special GPFS attributes, just the standard POSIX one, we plan to use 
the standard rsync.

The question:
is there any advantage in running the rsync on one of the NSD server or 
is better to run it on a client?

The environment:
GPFS 4.2.3.19, NSD CentOS7.4,  clients mostly CentOS6.4 (connected by IB 
QDR) and CentOS7.3 (connected by OPA), connection between NSD and 
storage with IB QDR)
