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
