The UltraSPARC T1 and UltraSPARC T2 are the first CMT processors designed by Sun Microsystems and these processors have been open-sourced and you can download them from OpenSPARC.net.

The UltraSPARC T2 Plus is the latest CMT processor and the Sun SPARC Enterprise T5140 and T5240 are the first systems to use this processor. The UltraSPARC T2 Plus is essentially an UltraSPARC T2 but includes multi-chip coherence links which allows systems to be built that use 2 or 4 of these processors together in one system.

You can read about the details of the UltraSPARC T2 Plus codenamed Victoria Falls made during a presentation at the HOT CHIPS 19 which was held on August 20-21, 2007, Stanford, CA. Victoria Falls - Scaling Highly Threaded Processor Cores
