RE: PowerHA and Journaling

Since PowerHA includes implementation of iASP, doesn't matter if you you use external storage or internal, as long as you migrate the IFS
folders to the iASP, PowerHA will replicate everything in the iASP, using storage block-page level, so you shouldn't care about journaling.

Please help me understand this. If you are *not* using journaling of your IFS objects what mechanism will bring your changes down to the surface of the disk so PowerHA can replicate them? To my knowledge the single level storage design will try to keep as much hot data as possible in main storage, and as long as they stay in main storage they will not get replicated.

Thanks!

Best regards
