ReiserFS only journals metadata, I thought? So there's not really duplication of effort, as ReiserFS will be journaling changes to inode structure and stuff like that while the redo log will be journaling changes to records in the various database table files.
I could be wrong about what ReiserFS does, though.
Talli, that's interesting. Perhaps the high-capacity DDR DIMMS haven't hit the end-user market yet but are available to OEMS?
