Sun has revealed two new Niagara servers: T5140 and T5240. Both of them have two UltraSparcT2+ processors which gives you 16 physical cores in a system with 128 threads in total. T5240, which is 2U version, also allows you to put up-to 16 SAS disks and up-to 128GB of memory - wow!
Prices - recently Sun re-priced old Niagara systems and now you can buy T5240 with 2x Niagara for the same price you could buy old 1x CPU Niagara system just a week ago - cool.
While T2+ has slighlty faster memory controllers but it has only two of them per CPU instead of four in T2... I wonder how it will impact performance.
