New Exalytics default storage configuration questions

Greetings,

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.

[[email protected] bin]# vgs

  VG         #PV #LV #SN Attr   VSize VFree

  VolGroup00   1   2   0 wz--n- 1.09t    0

  VolGroup01   1   1   0 wz--n- 3.27t    0

[[email protected] bin]# lvs

  LV       VG         Attr       LSize    Pool Origin Data%  Meta%  Move Log Cpy%Sync Convert

  LogVol00 VolGroup00 -wi-ao---- 1019.84g                                     

  LogVol01 VolGroup00 -wi-ao----   96.31g                                     

  LogVol00 VolGroup01 -wi-ao----    3.27t

[[email protected] bin]# df -H /u01

Filesystem            Size  Used Avail Use% Mounted on

/dev/mapper/VolGroup01-LogVol00

                      3.6T  208M  3.4T   1% /u01

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;

  1. Is this new configuration now standard and if so, why?
  2. 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;
