some questions regarding dumping databases to stripes.
how do we decide the optimal number of stripes in terms of performance for dump database?
afaik, the important factors are :
1. CPUs/engines
2. disk controllers
3. memory (-m parameter in backupserver)
if a filesystem/disk has only one disk controller, will striping improve performance in a database dump (even if there are multiple CPUs)?
likewise with only one cpu, will striping improve performance (even if the filesystem is controlled by multiple disk controllers)?
what are the cases if any, where stripes can only be as fast as a dump to a single file?
appreciate the insights.
