Disk Drive layout OLTP

Disk Drive layout OLTP

 

  

Is there an industry standard for disk layout on DB2? If so, could you guide me to it.
I'm talking SAN.
I know how to layout my files and have my disks configured for optimal performance on an OLTP system. Is there somewhere or someone that can assist me with this for DB2. Also, does it differ based on O/S ie, Solaris/AIX or Linux (SLES 10)?
Thanks
