Sun's 4-chip CMT system raises the bar

Find out about Sun's new 4-chip UltraSPARC T2 Plus system direct from the source: Sun's engineers.

Sun today announced the 4-chip variant of its UltraSPARC T2 Plus system, the Sun SPARC Enterprise T5440. This new system is the big brother of the 2-chip Sun SPARC Enterprise T5140 and T5240 systems released in April 2008. Each UltraSPARC T2 Plus chip offers 8 hardware strands in each of 8 cores. With up to four UltraSPARC T2 Plus chips delivering a total of 32 cores and 256 hardware threads and up to 512Gbytes of memory in a compact 4U package, the T5440 raises the bar for server performance, price-performance, energy efficiency, and compactness. And with Logical Domains (LDoms) and Solaris Containers, the potential for server consolidation is compelling.

Standard configurations of the Sun SPARC Enterprise T5440 include 2- and 4-chip systems at 1.2 GHz, and a 4-chip system at 1.4 GHz. All of these configurations come with 8 cores per chip.

The blogs posted today by various Sun engineers offer a broad perspective on the new system. The system design, the various hardware subsystems, the performance characteristics, the application experiences - it's all here! And if you'd like some background on how we arrived at this point, check out the earlier UltraSPARC T2 blogs (CMT Comes of Age) and the first release of the UltraSPARC T2 Plus (Sun's CMT goes multi-chip).

Let's see what the engineers have to say (and more will be posted throughout the day):
