All dual 2.4GHz Xeons, four with 36G SCSI, two with 40 G IDE disks,
RAM upgraded this week from 1G to 2G for the four biggest.

Plan to migrate the two biggest pairs to four pairs.

Software:
OS: RH Linux

ISC dhcp with our own LDAP patch, and the "next file" patch (see
http://nicku.org/software/) so that there is no need to restart the
servers except for dhcpd.conf changes.
Various log tailers to gather statistics and lease details all written
in Perl.
