sapdata recommendation for AIX/Oracle

Hello All,

We would like to know what is the best practice to have 4 sapdata or 10 sapdata for Oracle filesystem and distribution of data files.

We have a ECC of 18TB and BW of 25 TB on AIX 6.1 and Oracle 11.2.0.3. I am looking for long term recommendation for filesystem layout of sapdata.

Having 10 or more sapdata for a 10 TB size database would allow parallel read from the 10 different sapdata filesystem.

does anybody have any recommendation for the same.

Thanks,

Dnyandev Kondekar
