[CentOS] 'Extremely lazy' disk flush?

Are there any good options to configure a filesystem so most activity 
takes place in the RAM buffer with the flush to physical media allowed 
to lag very far behind?  OpenNMS does some data collection that keeps 
the disk very busy.  I don't want to lose the history completely in a 
crash like you would with a ramdisk, but it wouldn't be a big problem if 
only the last 10-30 minutes would be dropped.
