OpenSolaris Running Great on Intel Nehalem
By Roman Strobl on Mar 30, 2009
Intel has been a great partner for OpenSolaris in the last couple of years. Today, Intel is launching the new Xeon 5500 processor (also known as "Intel Core i7", codename "Nehalem") microarchitecture at a live event in Santa Clara. Intel has been working with Sun to optimize Solaris and OpenSolaris on Nehalem.
Solaris and OpenSolaris OSes are packed with optimizations specific to Intel Nehalem:
\* The Power Aware Dispatcher automatically monitors and optimizes a company's system to maximize performance while minimizing power consumption.
\* As a major contributor to OpenSolaris and an active participant in the OpenSolaris community, Intel has worked with Sun to port its PowerTOP technology to Solaris. PowerTOP utilizes Solaris DTrace to let developers and administrators maximize efficiency and monitor in real time how effectively a system is taking advantage of new processor power-management features like Intel Turbo Boost.
\* To improve reliability, the Solaris platform also provides predictive self-healing capabilities for systems based on Intel Nehalem. The Solaris Fault Management Architecture (FMA), which detects and automatically avoids repeated hardware faults in system components, has been extended to utilize status information from Intel Nehalem.
With these updates and optimizations, Sun and Intel have achieved a new world-record benchmarks for Solaris on the Intel Xeon processor 5500 series:
\* Two-tier SAP SD Standard Application Benchmark - This benchmark highlights the optimal performance of SAP ERP software on Intel Xeon-based systems from Sun as well as seamless multilingual support available for SAP ERP applications.
