Solaris Powers Intel Xeon® Processor 5500 Series Systems
Sun and Intel, as part of a strategic alliance, have been collaborating for over two years to enable the Solaris OS to unleash the power and capabilities of the new Intel® Xeon® processor 5500 series. As a result, the combination of the Solaris OS and the new Intel Xeon-based systems delivers the highest x64 performance, energy efficiency, and reliability available anywhere.  Get the datasheet
Performance
The Solaris OS delivers world-record performance on Intel Xeon-based systems across a wide range of workloads— from Web applications to mission-critical ERP applications— by taking full advantage of the advanced new technologies in the new Intel Xeon 5500 processor.

Power Efficiency
The Solaris OS now takes advantage of Intel's power management functions to improve energy efficiency and performance-per-watt through Integrated Power Gates and Automated Power States.

Multi-chip, Multi-core, Hyper-Threading, Turbo Boost Technologies
Solaris has delivered near-linear scaling across multi-CPU systems over the past decade. Now that capability fully leverages the power Intel designed in their new Xeon-based systems. For example, the Solaris OS advanced scheduler automatically sends work close to the data in memory for the fastest execution. And it leverages Intel's new Turbo Boost mode, which cuts the power of unused cores to speed the active cores, improving single-threaded application performance automatically.

New Power Aware Dispatcher
Together with Intel, we integrated an innovative Power Aware Dispatcher (PAD) into OpenSolaris to maximize performance while minimizing power consumption. It intelligently schedules processes and threads to take advantage of Intel's advanced processor power states (P & new deep-C states), and Intel Turbo Boost Technology.
Reliability
Increased reliability, availability, and serviceability (RAS) comes from the Solaris Fault Management Architecture (FMA) infrastructure, now enhanced to take advantage of the new Intel Xeon systems. Solaris is known for its datacenter reliability with uptimes measured in years, not days or weeks.

Faster I/O, Unlimited Data
Solaris ZFS is the award-wining file system that provides a nearly unlimited storage capacity coupled with RAID-Z, which never loses your data and gives you the flexibility to create enterprise-class storage systems with open server components. Intel's Quick Path Interconnect removes I/O bottlenecks between the CPU and storage devices so you can get great application performance and tremendous I/O throughput with Solaris on the new Intel Xeon 5500 processor.

Looking Out for You and Your Systems
Get up to 2x the memory and I/O capacity of competing blade servers. You can pick a blade that will meet your application requirements: Sun offers up to 256 GB of RAM and up to 270 Gb/s throughput to handle the most demanding, throughput-hungry applications.

Advanced Performance Features for Developers
The Solaris OS now exposes the new Intel SSE4.2 instruction set built into these new Xeon processors, and developers can take full advantage. The instructions are now implemented in hardware, rather than by software running on the CPU. The result is much faster execution and a reduced load on the CPU. For details on leveraging these new instructions, see the new Solaris on Xeon 5500 BluePrint.
