Sorry for the confusion. Let me rephrase the question.
The question relates to placing the 'online redo
logs'. Based on the current activity, the 'archived
redo logs' amount to ~960G a day. That number is used
only to demonstrate that it is a busy system.
One option given to us by the Unix admin is to use
Raid 10 as we have been using for rest of the
datafiles. Other is to attach 3 EMC Hyper Devices,
that have their own set of cache pages. I'm not sure
what he means by the second option though and how
reliable that would be.
Thanks,
Deepak
