Sun Fire's dynamic reconfiguration allows the addition or removal of system resources -- CPUs, memory modules, I/O -- without shutting down the operating system or powering down the system itself.
Components such as I/O cards, power and cooling, and even the system clock are fully redundant. The system interconnect is redundant and reconfigurable.
Sun Fire E6900 servers capture the ongoing history of key system components, including data on installation, power, temperatures and soft (memory) errors. In the event of some of the most common errors, Proactive Self Diagnostics provides easy-to-understand diagnostics and identifies which components have been affected.
The Sun Fireplane Interconnect is a packet-switched, crossbar architecture. It provides high sustained bandwidth of 9.6 gigabytes per second and very high aggregated bandwidth, up to 67.2 gigabytes per second.
