I run an Oracle 7.3.2.2 database on Veritas filesystems with good results. I have used straight concatenated disks and the performance is good. I also switched to RAID5 filesystems and found that you must enable fast writes on your disks in order to get fair performance from the filesystem. I would not recommend a RAID5 filesystem for the an Oracle Database unless you don't care too much about performance. Another option that would probably work better than RAID5 is RAID0 which is less complicated on the write side and therefore probably offers better write performance.

I see no detriment in using Veritas Filesystems,in fact there are several things that make using Veritas/Sun Volume Manager a good choice including utilities like `vxstat` which will show you how your volumes are performing.
Good luck.
