I'm curious if anyone feels that the new AIXDIRECTIO option in TSM 5.1
affects their opinions about how to utilize disk for storage pools.  TSM
5.1 also has an Async I/O option (AIX).  For more info, refer to
<http://www.redbooks.ibm.com/redpieces/pdfs/sg246554.pdf>, starting at
about page 107.  The AIXDIRECTIO option does not work with
large-file-enabled filesystems, so the filesystem must be 2GB or
smaller.  This option bypasses VMM file cache.
