Sun is rolling out the first three servers based on its 64-thread UltraSparc T2 processor, previously code-named Niagara.
The first systems integrating the T2 CPU will be the rackmount servers T5120 and 5220 as well as the T6320 blade module.
All three systems will be available with T2 processors clocked at 1.2 GHz or 1.4 GHz. While the 1.4 GHz model is only available with eight cores, the 1.2 GHz version can also be purchased with six or four cores. ALL CPUs are capable of running eight threads per core and up to 64 different operating systems (8 cores x 8 threads) in virtual containers.
