Hi,
We recently migrated from sun a5200 storage to EMC symetrix, and we have been seeing occasional performance problems. When contacted, Oracle support among other things pointed out the stripe width we have used 1M, is very large and also said users will not see an advantage above 64K.

When we had Sun storage before we had 64K as the stripe width.

Has anyone faced this kind of issue or has any comments..or can someone explain the low level impact of the stripe width on the ORACLE I/O operations?

Much appreciated..

Regards
