New Exalytics default storage configuration questions
Our company has several Exalytic machines, but we have just received a new delivery of an Exalytic X5-4 machine on which the default storage configuration is confusing.
As shown in the outputs below, the logical volume that /u01 belongs to is completely dedicated to the /u01 file system.

This server is slated to host multiple instances. Our older systems all arrived with the /u01 logical volume sized at 100Mb and as such, individual instances were placed in their own logical volume and /u01 became a mount point. The current configuration does not allow this which brings me to my questions;
- Is this new configuration now standard and if so, why?
- If our company were to shrink the /u01 logical volume to a smaller value, would this be supported by Oracle?
For reference, here is the output of exalytics_imageinfo;
