ASM normal redundancy

Sarat_yahooSep 3 2016 — edited Sep 8 2016

Hello Gurus -

Version : 11.2.0.4

Configured with ASM/FSF/Oracle Restart

Database size : 3 TB

Each size of disk is 1 TB

The current architecture of +DATA diskgroup is normal redundancy, has for every disk an own failure group. I am not familar with ASM - I have couple of queries, can you please give me some light on this?

1) What are advantages for having each disk an own failure group, compare to having separate failure groups?

2) Suppose if I have two failure groups ( FAL 1, FAL 2) with two disks each - If one failure group (FAL 1) is crashed (two disks became offline) - Do i lose my data?

3) Also as per my current environment architecture (normal redundancy) i.e., every disk an own failure group - In this case If two disk became offline - Do i lose my data? or my ASM stop working?
