I have an environment that backups up data via IP to DD2500. We then use Networker to clone backup jobs to LTO-6 PTL (2 tape drives) all over DD boost over FC.
There is a storage node configured solely for tape out so all tape out traffic is on the SAN (FC).
We currently see about 80 MB/s per tape drive with some spikes to 100 MB/s here and there.
My question is, for anyone that has a similar set up (DD2500 -> PTL via FC), what speeds are you guys seeing? I've optimized block sizes and ran additional sessions for clone jobs but seem to be capped at around 80.
