Journal config for SAN array

The thread in this forum about using SSD for journals...

leads me to ask:

What is the best way to configure journals for about half a dozen servers
accessing some twenty file systems hosted on a RAID-5 SAN array?  The array
holds relational databases which are used in an OLTP style by web-based
apps, so it sees lots of small-ish, nonsequential transactions.  Presume the
array has enough physical disks and cache to provide normally acceptable
performance.  None of the file systems on the array are shared: each file
system is mounted (and zoned and masked) to one and only one server, though
there may be several file systems on a server.

Thanks in advance!
