What Is Asm Striping?

1.	What Is Asm Striping?
Answer» ASM can use VARIABLE size data extents to support larger files, reduce memory requirements, and improve performance. Each data extent resides on an individual disk. Data extents consist of ONE or more allocation units. The data extent size is: Equal to AU for the first 20,000 extents (0–19999) Equal to 4 × AU for the next 20,000 extents (20000–39999) Equal to 16 × AU for extents above 40,000 ASM stripes files using extents with a coarse method for load balancing or a fine method to reduce latency. Coarse-grained STRIPING is always equal to the effective AU size. Fine-grained striping is always equal to 128 KB. The data extent size is: ASM stripes files using extents with a coarse method for load balancing or a fine method to reduce latency.
