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.
- 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.
