Oracle 11G ASM configuration with EMC storage guideline?

Hi Experts,

I know EMC has some recommendation for ASM configuration for Oracle 10G:

ASM disk group configuration guidelines

• Use multiple disk groups – preferably a minimum of four, optimally five;

place the Data, Redo, Temp, Undo, and FRA/archive logs in different

(separate) disk groups

• Optimally, use RAID 1 for tier-1 storage

• Use external redundancy instead of ASM mirroring

• Configure disk groups so that each contains LUNs of the same size and

performance characteristics

• Distribute ASM disk group members over as many spindles as is practical for

the site’s configuration and operational needs

From what I heard, Oracle 11G ASM has huge difference from 10G. Has EMC published any guideline for ASM configuration? Thanks.
