Scale more with less with Sun's 3rd generation CoolThreads design: 16 cores, 128 compute threads, 16 disk drives, and 256 GB of memory in a 2RU space. The Sun SPARC Enterprise T5240 server is the fastest 2-socket server available, with up to 5 times the performance in half the space and 2.5 times better performance per watt than comparable x86 systems.
