On the positive side:

It provides a single point of support so there is no finger-pointing.
It provides easy management of block devices (raw partitions).
It automatically moves hot blocks to the outside of the disk.
It is vendor and operating system neutral.
It, additionally, provides all of the features of an LVM.
It is included in your license so no additional cost for the software or its support.

But does Oracle gain control over the storage system? I don't see how this is any different from letting any other vendor supply an LVM.
