Running DB2 8.2 on AIX5.2

When a new application was installed, a consultant recommended that
large tablespaces be defined with just one container, given that the
container was striped into a raid10 array of discs.

There are 2 or 3 other heavy hit tablespaces that share that array.

In this type of raid10 environment, is there any performance advantage
to be gained by breaking up a heavy hit tablespace into separate
containers onto separate hdisks in that array?

Have checked a number of resources .i.e Database Performace Tuning on
AIX.

Is that the best resource possible for the data placement aspect of
tuning in reagrds to Raid arrays?

Thanks in advance.

Not likely.

How did you determine that it's the physical layout of containers that impacts the performance of your system?

When we would get reports of slow performance we noticed ceretain in topas that certain hdiscs were getting slammed. IBM just replied that there is no performance gain to be had by going to multiple containers on a raid 10 and recommended a REdbook..DB2 Performance Guide for OLTP that I am going through now.
