Hi George,

You can find a lot of info on ASM internals at this blog: http://asmsupportguy.blogspot.com/

A few years ago I also did some research on the subject. I guess the wiki page I wrote at the time with some of the findings can still be useful (although not fully up-to-date with the latest Oracle versions): https://twiki.cern.ch/twiki/bin/view/PDBService/ASM_Internals

Best regards,
Luca

Subject: ASM Block distribution

Hi all

I remember when ASM just made it's appearance there was a paper available that explained how ASM distributes blocks when configured in normal or high, thinks like primary block owner and 8 potential partners for each asm disk.

Any chance anyone has this lying around, or have an updated version taking Exadata Storage servers into consideration.

My curious side at work.

Yours Sincerely
