AFAIK, EMCs Controlcenter dbtuner is just SAN and disk array tuning utility
with integration to major database vendors software (i.e. you can see on
which actual disks your datafiles reside, allow resolving disk bottlenecks
etc..).

But OEM is whole Oracle database management software, not just limited to IO
tuning. Actually Oracle9i has IO topology feature, which should be able to
help on (or help to understand better) physical disk issues with EMC and
some other vendors, but I think EMC's software is much more mature
currently.
