Since I am the lone DBA in my company, I would like to bounce some decisions i need to make. I am setting up a 2 node RAC on HP-UX and my question is about placement on the NON raw files and diretcory structures. Specifically, whether to place certain directory file systems on the HP boxes internal drives or on the external disk enclosure. The internal drives will be R0+ 1. The external disk enclosure will have a mixed bag of raw devices and file systems, all RAID0+1.

So, in your opinion, where would you put the following file systems?
Server internal drive or External disk array?

/oracle (for node 1) oracle binaries (instances will NOT share)
/oracle (for node 2) oracle binaries (instances will NOT share)
/archive_thread1 – archive logs for thread1
/archive_thread2 – archive logs for thread2
/backup_thread1 - misc backups NOT rman
/backup_thread2 - misc backups NOT rman
/backup - RMAN backups to disk prior to going to tape
/export
/data - This is basically the output of UTL_FILE dir

Much thanks for your opinion!
Frank
