SunFire Enterprise 20K

The Sun Fire E20K server is a high-performance, high-end data center server that scales up to 36 UltraSPARC IV processors with chip multithreading technology executing 72 simultaneous computing threads. With these processors plus new hsPCI+ I/O assembles, the Sun Fire E20K provides up to twice the compute density in the same footprint and enhanced I/O performance for lower total cost of ownership. High availability is delivered with 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. It is also hot-upgradeable to the Sun Fire E25K server for a seamless upgrade path with no disruption to service. This server is available in the Sun Customer Ready Systems (CRS) program for factory integration into ready-to-deploy, customer-specific solutions.
