Installation on SAN is good but on NAS may not be a good idea. Top level mounts are ok but separate mounts for resource scratch may be better. And From my experience minimum of 0.5x of swap space is required, 2x recommended.
Its my opinion, which may differ for 11.5 (haven't worked on that) or someone may have some better suggestion.

Genius may have its limitations, but stupidity is not thus handicapped.
Not a lot of benefits for separate mount points if on the same SAN if they share the same physical drives. The only benefit is the size of the disk space is reduced. The SAN itself tries to spread the load and most are not optimized for ETL. There is usually lots of buffering in the SAN which helps a lot.
Few years ago, file system hosting the DataStage project ran out of space, subsequently many of the jobs were corrupted. Now it is part of our standard practice to isolate data/scratch directory on separate mountpoints.
Do we know where to change this options we are doing 11.5 install on NFS faced some issues IBM is recommending to do the same but our NAS Team has no clue what it means.
