IBM PowerHA SystemMirror- Vikas
As we are running with critical applications and databases including oracle, db2, and others. To make them highly available we are using Power HA System Mirror which is helping to run the environment with minimal downtime window in case of worst scenarios as well as in case of maintenance which is helping a lot in my business.

As I am having long experience with this so no doubt, I am very confident for it where I can deploy easily and manage easily in terms of any issues can go with multiple logs and take further actions on it to fix the issue in a swift manner which matters a lot to me. That's why I have given higher priority to it.

IBM PowerHA Use it or Not!!!
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.
- 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.
- 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.
