or more specifically... would the "additional disk space for ASM metadata" be on 3 separate disks or be part of the database storage disks?

Finding the manual confusing when it explains how to set up storage. This is 11gR2 on linux. The install guide indicates I will need: assuming for normal redundancy minimum 3 disks of 1.5GB each for Clusterware minimum 2 disks 9GB each for database storage and additional disk space for ASM metadata -- at least 3 disks of 2GB each. Putting it all together -- Does this mean I need 8 disks minimum? or would some of these normally be combined? Thank you in advance!
