IO tuning for multiple parallel DVD readings
Objective: copy old backups from 600+ CD/DVD media to a hard disk.
Machine: A desktop with 4 DVD drivers, mainboard has 4 SATA conectors and only one PATA conector.
My questions are:
1. What tuning can I do to the kernel on a Ubuntu Lucid Desktop to achieve maximum IO to dd/cp/rsync/whatever those medias to hd?
2. What's the best scenario regarding HD/DVD drive connections to mainboard regarding IO/throughput?
The intention is to insert 4 medias at a time and copy them all in parallel to a local hard disk.
Any thoughts, hints, insights? I confess I am completely lost where to begin, or if this should work out-of-the-box without any tuneup (will try this).
Thanks and best regards.
