Features and Benefits

 

High Performance
Feature Function Benefit
2nd generation dual-core processor design. Increased throughput The UltraSPARC IV+ processor features a design that's much improved over the UltraSPARC IV processor—including enhancements to its dual-cores utilizing the latest 90nm process, which enables frequency improvement through smaller transistor sizes.
Chip Multithreaded Technology. Increased throughput The UltraSPARC IV+ processor uses Chip Multithreaded Technology that supports two simultaneous threads as a result of two independent cores. Operating at 1.5 GHz, the UltraSPARC IV+ offers up to five times the performance of UltraSPARC III servers and up to double increased performance over UltraSPARC IV servers in the same footprint, with no increase in power and cooling requirements.
Mission-critical throughput Highest reliability and availability Sun's UltraSPARC IV+ processor provides a unique combination of real world application performance and exceptional product quality for mission-critical enterprise, High Performance Technical Computing (HPTC), and other compute-intensive applications.
Core enhancements. Increased performance The UltraSPARC IV+ processor features core enhancements optimized to increase application performance.
Investment Protection
Feature Function Benefit
Application compatibility guarantee Customer investment protection Sun's UltraSPARC IV+ processor protects customers' investments through the Solaris 100 percent application compatibility guarantee on all previous SPARC implementations.
Painless upgrade. Protects customer software investment Sun's UltraSPARC IV+ processor provides a natural upgrade path for midrange and high-end UltraSPARC III and IV processor-based systems by enabling in-chassis upgrades.
Protects your training investment. Leverage existing resources The Solaris OS compatibility guarantee protects customers' software and training investments across time and product lines.
Reliability
Feature Function Benefit
Wide ranging support. Leverage ISV community The UltraSPARC IV+ processor and the Solaris Operating System support a wide range of applications with enterprise-class reliability.
Solid interconnects. Highest reliability ECC or parity protection on all interconnects results in enterprise class reliability, availability, and serviceability.
Reduction in soft errors. Highest reliability The new UltraSPARC IV+ processor delivers a 3x reduction in already-low soft error susceptibility, even with a 5x increase in the number of transistors.
