Sun Fire X4640 Server Features and Components

The Sun Fire X4640 server takes full advantage of the exceptional power and performance of the AMD Opteron processor. The server is a four rack-unit chassis capable of supporting up to eight vertically-mounted customer-replaceable (CRU) CPU modules. Each CPU module is a single-board unit containing a CPU, eight DIMM slots, and on-board diagnostics.

This server provides the following maximum system configurations:

This server is 24 inches (610-mm) deep and is compatible with all data center 28-inch (711.2-mm) racks. Airflow is strictly front-to-back and supports the highest-performance Opteron CPUs at 95° F (35° C) ambient temperature.

Standard I/O includes four 10/100/1000BASE-T Gigabit Ethernet ports, VGA video, serial, four USB ports, and one 10/100BASE-T Ethernet management port. An SAS on-board disk controller supports up to four SAS disk drives.

The Sun Fire X4640 server includes an extensive set of Reliability, Availability, and Serviceability (RAS) features, such as hot-swappable and redundant hard disk drives (when RAID1 is used), fans, and power supplies. The servers also provide an integrated lights out management (ILOM) service processor function, which includes remote boot and remote software upgrades.
