Can anybody give me an idea of the potential overheads incurred when using
LSM striping and LSM mirroring together in the same configuration? I
currently have a system that LSM volumes constructed of 4 plexes (2 local, 2
remote via fibre channel), and each plex is formed as an LSM stripe from 3
HSG controller based stripes (complicated or what!). I'm trying to get a
feel for whether the evalated system time I'm seeing is a result of the 4
plexes, the LSM striping or both. In addition if anyone has tried this sort
of thing before, found benefits, drawbacks, gotchas etc. I'd be keen to
known. I'm personally inclined to rip out the LSM striping from a management
overhead perspective - but I'd like to get some feedback from a possible
performance point of view to back up my decision.
