Hello All,



We are planning on testing a two node 10g RAC using ASM for one of our 
database on pSeries using AIX 5.3. We have a primary requirement of 
mirroring data across TWO data centers (Hitachi SAN).  I have two questions



    
  
  1.   Mirroring.






   Can we use AIX Volume Manager to take care of the mirroring or ASM to 
do mirroring. I am specifically looking for HOW and WHY?



2. Striping



    I have seen a similar post just a few days ago on ASM striping, 
although i couldn't understand much of it (Pardon my knowledge on disk 
technologies). Our storage folks told me that, they have a huge disk 
cache (128 GB) and very high performing SAN (HDS 9980) w/ excellent 
algorithm for striping the LUNS across multiple disks. So HOW best I can 
use ASM striping along w/ HDS storage striping? or will it cause any 
performance problems??



Please advise me...



Good Day,


Madhu
