Is Asm Constantly Rebalancing To Manage “hot Spots”? |
|
Answer» No, ASM PROVIDES even distribution of extents ACROSS all disks in a disk group. Since each disk will EQUAL number of extents, no single disk will be hotter than another. Thus the answer NO, ASM does not dynamically move hot SPOTS, because hot spots simply do not occur in ASM configurations. Rebalance only occurs on storage configuration changes (e.g. add, DROP, or resize disks). No, ASM provides even distribution of extents across all disks in a disk group.
