Secure Deletion of Data from Magnetic and Solid-State Memory by Peter Gutmann of the University of Auckland. This paper covers some of the methods available to recover erased data and presents schemes to make this recovery significantly more difficult.
fwipe securely erases files and is immune to filenames containing spaces, carriage returns, dashes, or any other special characters. Free software.
Secure Delete is a set of three utilities to perform secure deletion of files, secure overwriting of the unused diskspace on the harddisk, and secure overwriting and cleaning of the swap filesystem. Free Software.
srm (secure rm) is a command-line compatible rm(1) which destroys file contents before unlinking. The goal is to provide drop in security for users who wish to prevent command line recovery of deleted information, even if the machine is compromised. Free Software.
TCT and unrm/lazarus tools to verify the deletion of files:

scsiinfo, written by John DiMarco is great for debugging Sun SCSI device problems.
dio is a Solaris utility that monitors the I/O from any device on a Solaris machine. The device can be a disk partition, an entire disk, a metadevice created with Disk Suite or any other kind of I/O device. Practical uses include visualising the flow of data to and from a file system, performance checking a new disk configuration. GPL licensed, source and binaries freely available.
HA/FST Free high availability clustering software for Solaris. HA/FST works similar to other HA tools. Heartbeats sent across a private network are monitored. If these heartbeats fail and subsequent checks across the public network fail, then a failover can occur. Additionally, each application is monitored at configurable intervals for soundness. Application failovers can trigger a restart or a failover.
