Sun recently announced the Sun SPARC Enterprise T5120 and T5220 and Sun Blade T6320 systems based on the UltraSPARC T2 processor. You can find lots of information on the various features and functionality provided by these servers.
One other cool feature is that these systems ship with Cool Stack pre-loaded. The Cool Stack 1.1 packages are available in /var/spool/pkg. You can install the ones you want using the pkgadd(1M) command as follows :
root@wgs40-82 # cd /var/spool/pkg
root@wgs40-82 # ls
