Not too long ago word came out that Sun was preparing the release of two new workstations, one Opteron and the other UltraSPARC, because it had published manuals and pricing. Now, the machines appear to be officially on sale, even though announcements have not been made yet. First of is the Sun Ultra 40, the bigger and badder brother of the Ultra 20. It can handle up to two dual-core Opteron processors, and 16GB of memory. Secondly, we have the Ultra 45, an UltraSPARC IIIi-based workhorse, holding two UltraSPARC IIIi processors at 1.6Ghz each, also capable of 16GB of RAM.
