COARSE STRIPINGIt is used for all voluminous input/output, e.g. input/output operations on datafiles.The size of the coarse grained data stripes is large.It manages the load balance across the disk groups.The size of the coarse-grained stripe is always equal to the size of ASM Allocation Units (AU).The size for coarse striping can be set using the _asm_ausize parameter.
FINE GRAINED STRIPINGIt is used for all small input/output, e.g. input/output operations on online redolog files and control files.The size of the fine grained data stripes is small.It spreads the load on disk groups reducing latency for certain file types.The size of the fine-grained stripe is always 128 KB.The size for fine grained striping can be set using the _asm_stripesize parameter.
