Overall Satisfaction with IBM PowerHA SystemMirror

PowerHA is currently used by the IBM Power Infrastructure Support group for high-availability clustering and to replicate our user profiles to our DR infrastructure. Is also use for asynchronous geographic mirroring and space-efficient FlashCopy where we perform our backups.

Pros

  • Asynchronous geographic mirroring extends the host-based replication to our DR environment.
  • FlashCopy provide us with a point in time snapshot of our Production environment from which we can run our daily backups without downtime.
  • Since PowerHA runs at the kernel level it allows the system to send a message from the primary system to the backup or secondary system when the node has crashed.

Cons

  • IBM Sybase replication has been an issue for those who don't [use] MIMIX on their systems to keep the Sybase up to date.
  • The graphical interface really needs an update.
  • Technical support isn't as responsive as it should be.
  • The inability to maintain our Sybase up to date with IBM PowerHA SystemMirror
We installed IBM PowerHA SystemMirror to perform the clustering and switching functionality.

If you have an environment where you have to replicate your Sybase I would recommend an implementation that includes MIMIX for PowerHA as part of the entire environment, but if you have a Sybase that never changes and you run all your applications on an iASP the IBM PowerHA SystemMirror is the solution for your business.
