The Sun Fire E25K server is Sun's massively scalable, highly available flagship data center server that scales up to 72 UltraSPARC IV processors with chip multithreading technology executing 144 simultaneous computing threads. With these processors plus new hsPCI+ I/O assemblies, the Sun Fire E25K provides up to twice the compute density in the same footprint and enhanced I/O performance for lower total cost of ownership. The Sun Fire E25K supports over 1/2 TB of memory per domain, making it ideal for mainframe migration, consolidation, decision-support, and other memory-intensive applications. High availability is delivered through Full Hardware Redundancy, fault-isolated Dynamic System Domains, and Dynamic Reconfiguration for hot swapping key server components while applications are up and running, for higher availability. Investments are protected with the ability to mix and manage UltraSPARC IV and UltraSPARC III processors--running at their rated speed--in the same system. This server comes remote-services ready for preemptive support and preloaded with a rich set of applications with the Java Enterprise System. This server is available in the Sun Customer Ready Systems (CRS) program for factory integration into ready-to-deploy, customer-specific solutions.

* Upgrades : The Sun Upgrade Advantage Program (UAP) offers trade-in value for qualified Sun and competitive servers towards the purchase of replacement Sun Fire E25K servers. Whether upgrading one system or consolidating many systems to one, Sun UAP offers the flexibility to trade-in systems and receive credit towards the new Sun system purchased. Upgrades are also available for Sun Fire server system component upgrades including CPU/memory boards, and I/O assemblies.
