Solaris OS on Nehalem-EX white paper

Sun has recently published a white paper that discusses how the Solaris OS will take advantage of the future Intel Nehalem-EX processors. With over 20 years of SMP expertise, what better OS than Solaris to run on top of Intel's future 8-socket, 64-core, 128-thread architectures? With features such as Memory Placement Optimization or Predictive Self Healing, the Solaris OS has the critical technologies necessary to large SMP architectures today. The paper discusses the collaboration between Intel and Sun to optimize Solaris for Nehalem-EX and leverage new features such as Hyper-Threading, QuickPath Technology, Turbo Boost Technology or I/O acceleration.

All the details in the paper  "The Solaris OS and Intel Nehalem-EX".

Increase the memory bandwidth by 12% with a BIOS upgrade

Sun has engineered its Intel Xeon 5500 (Nehalem-EP) based servers to reliably operate at 1333 MT/s with two DDR3-1333 DIMMs populated per channel. The increase in bus speed results in up to 12% memory bandwidth improvement. This mode can be enabled after a software update download from sun.com.
