Going with a 3Ware SAS controller.
Have some external enclosures with 16 15Krpm drives. They are older
15K rpms, but they should be good enough.
Since the 15K rpms usually have better Transanctions per second I will
put WAL and indexes in the external enclosure.
It sounds like you have a lot of hardware around - my guess it would be
worthwhile to do a test setup with one server hooked up with two 3ware
controllers. Also, I am not sure if it is wise to put the WAL on the
same logical disk as the indexes, but that is maybe for a different
thread (unwise to mix random and sequential io and also the wal has
demands when it comes to write cache).
