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
