OpenSolaris Running Great on Intel Nehalem

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.

For more information, visit the Sun Intel page. There are serveral engineering videos available which discuss Solaris and OpenSolaris on Nehalem.

Also make sure to check the video from Dave Stewart of Intel discussing Intel and OpenSolaris.

That was a great information regarding Nehalem.

Its actually a great excitement everywhere regarding Intel's Nehalem and now this would also add fire to it.

Especially I'm more concerned about the power consumption which is reduced by 30%...

Hi Roman,

Thanks for the great post and links.

It looks like the power management features built into these new processors should help to achieve lower idle power consumption.

Do you know if the Xeon E5500 series support ECC memory?
I.e. if I get an LGA 1366 X58-based mobo plus a Xeon E5504 processor and unbuffered ECC RAM, will I get ECC support? I was considering the Supermicro X8SAX mobo:
http://www.supermicro.com/products/motherboard/Xeon3000/X58/X8SAX.cfm

I thought that with Nehalem the memory controller has been moved into the processor, so am I correct in assuming that the ability to use ECC RAM is now a feature of the processor and not some off-processor memory controller chipset?

Cheers,
Simon

I like to see Intel is always looking for a way to improve the level of attractiveness of their processor, add some new useful features, etc.
Probably that is why I am a big fan of Intel and all their products =)
