I've always worked on the basis that OS or hardware mirroring
ofers better performance than Informix mirroring, but at the
same time always set your dbspaces up with mirroring enables (1)
but don't specify a mirrored chunk path. It takes no overhead
and offers an alternative 'get-out' route (where you could
add a mirror chunk) in the event of some problems.

->
-> I'm currently installing a new system (obvious due to prior
-> postings).
-> It's running on a Linux-OS, and I'm using software RAID1 for data
-> security. Question is: What's better performance-wise, to use the
-> OS-level mirroring, or let Informix do the mirroring?
->
-> Also, as our customer plans on running a second server as hot-standby
-> machine, we will configure DRBD to update a filesystem area - what's
-> better there, DRBD or using Informix' replication features? Both from
-> performance and security/reliability point of view? (with more weight
-> on reliability of course)
->
-> Tnx!
