Typically, we use a 3Ware controller, with anywhere from 2 - 16 individual hard-drives attached. Although we use 3Ware's tw_cli tool in both a daily cron-job and also in a Nagios monitor, it's also a good idea to get a daily logwatch-email stanza with drive-statistics and alerts. Belts and suspenders, you know.
In addition to (passive) monitoring, we actively invoke Long Self-Tests on each drive. These tests are scheduled to try to hit low-usage times, and also avoid our tape-backup times.
Install the (Gentoo) package:
hostname # emerge -av smartmontools
Start the smartd monitoring daemon automatically in the default runlevel:
hostname # rc-update add smartd default
Representative configuration file:
hostname # emacs -nw /etc/smartd.conf
# This file: /etc/smartd.conf
# created April 14, 2010, Gordon Pritchard
# Monitor 16 SATA disks connected to a 3ware 9650 controller which
# uses the (built-into-kernel) 3w-9xxx driver.

In order to find what parameters are available for monitoring or ignoring, issue the smartctl command:
hostname # smartctl --all /dev/twa0 -d 3ware,0 (of course, change the 0 to any other 3Ware-connected drive you're interested in)
