This is why we have found and followed ...
- each db has its own DG's (data + fra) for accounting and sla
- for rac, we have 3; data, fra, and grid
  • number and size of luns per dg for a db is a function of current and projected db growth. It happened that we use 100g luns.

As far rules, this is what i know ...

ASM has the following size limits:

•  63 disk groups in a storage system
•  10,000 ASM disks in a storage system
•  1 million files for each disk group

Thank you.
