Mirror or Raid1? Replication or DRBD? 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! |
