Hello all,

does anyone have a "rule of thumb" as to how much Replication for disaster recovery slows down overall disk I/O?

We are replicating about 45 terabytes from HDS USP using asynch. We recently had issues that slowed our mainframe to a crawl. The work around was to stop replication. During the time replication was shut down our batch ran twice as fast as it does with replication up.

Regards
Manshadi
