Specifications
Imagine: one chip, eight cores, 64 threads. Plus integrated 10 GbE networking (UltraSPARC T2 only), crypto, and PCI-Express expansion. Let's add Solaris 10 to the capabilities, the free and open source OS, and no-cost virtualization with a choice of Logical Domains and Solaris Containers. We introduced Sun's second and third generation CMT processor while the rest of the industry is straining to catch up with our first generation.
