Hi,
we are in the middle of choosing the most suitable standard for our estate
for I/O. we are using vxfs as filesystem and I wonder if any one in the
list can share their experiences on using Oracle Disk Manager (odm) or
Concurrent I/O and why would I chose one on another.
in the past on 10g, I experienced very slow backups from DR site when ODM
is used. Never had chance to be in a position to test both on the same
application but I experienced very good improvements by using CIO to attack
log file sync issues.
on the paper odm looks like it has more features around block management
which I'm not able to prove so I wonder if the features on the paper are
still valid for 11g.
For me , What really matters is performance. During our tests, If CIO
performs way better then cio will probably the the best choice but if the
difference is not big then benefits from ODM will probably impact the
decision as the features on paper attracts the platform guys.
appreciate if any of you can share your experiences
Thanks in advance
by the way asm is not an option.
