Solaris Volume Manager & soft partition striping

I have a Sun V880 with 6 internal 72GB drives that I need to configure
as a database server (Oracle 10g). The Oracle data layout consists of
20 separate filesystems (e.g. dbfs01, dbfs02, dbfs03, etc.) of varying
sizes ranging from 2GB to 32GB. There's also a requirement that each
file system be striped across 3 disks (RAID 0).

Using Solaris Volume Manager it doesn't appear as though there are a
sufficient number of physical slices/partitions for the stripes though
it does seem that soft partitions may work. What would people recommend
regarding setting up striping with soft partitions to attain. For
example, create 2 large soft partition stripes comprised of three disks
each (minus root, swap & metadb partitions) and create the Oracle
filesystems within those soft partitions. Are there other approaches
folks would recommend? Thanks.
