has anyone experiences with VTL self Deduplication Backup Appliances, like Quantum DXi4800 for Example (smaller Modells ~27 TB)? The deveices are non Deduped backuptargets for commvault. Later Aux-Copy to a physical Tape-Library is performed.
I got a Performance Best Practice Guide from Quantum. They said use small cartridge size 50/100 GB (like Ultrium 1) but not how many Tape Deveices in parallel and how this relates in backup and restore performance.
To much Tape-Drives maybe slow down the throughput but i have no idea which throughput per drive stream is possible comparred to a physicale tape drive which normaly only receive 100-200mb/s.
Would be nice if someone else use this "old"stuff and can explain something in correlation with commvault. My last VTL implementation was 10 years ago.
