High Performance

Sun's new UltraSPARC IV+ 64-bit Chip Multithreading (CMT) processor has significantly enhanced cores, 2-MB on-chip L2 cache, and a new 32-MB L3 cache using the latest 90nm process technology. It delivers over 5 times higher performance than UltraSPARC III servers, and over double the performance of previous generation UltraSPARC IV servers in the same footprint. The UltraSPARC IV+ processor is supported in previous generation Sun Fire E25K and 15K servers via in-chassis upgrades
Exceptional scalability:

The new Sun Fire E25K server extends Sun's tradition of reducing risk and enabling customers to comfortably scale capacity. As the lead member of the industry's most scalable server line, it scales up to 72 processors, executing up to 144 simultaneous compute threads, and supports up to over 1TB of memory to provide maximum headroom for data-intensive applications.
Run demanding applications:

The new Sun Fire E25K server delivers significant productivity gains to address ever-demanding data and business logic workloads such as business processing, databases, data warehouses, IT infrastructure, application serving, and compute-intensive scientific engineering applications.
Dynamic Tracing:

DTrace allows real time data collection and analysis of production systems, enabling customers to optimize application performance up to 30x.
