Rugged Servers


Galleon's rugged Servers are high-performance systems for the most demanding deployed applications. They are designed to meet the most severe environmental conditions without compromising on functionality and performance. The high performance allows server virtualization in size constrained applications. The Size, Weight and Power (SWaP) optimized design makes them ideal for use in small unmanned aerial and ground systems, as well as large manned aircraft and vehicles.

Intel Core Xeon processor options, including the latest 11th generation, are supported with up to 96GB of DDR4 SDRAM with ECC. The flexible I/O architecture allows easy integration with existing infrastructure. Up to eight 10Gigabit Ethernet ports or thirteen Gigabit Ethernet ports are supported, which lends the unit ideal for network-attached storage (NAS) applications. The high number of Ethernet ports can eliminate the need for external switches, but the system can also be supplied with and 8-port internal Gigabit Ethernet switch.

Optional FIPS 140-2 and AES-256 hardware encryption provides a high level of data security with flexible key management options, including physical key tokens through front panel key loading port and remote loading over a secure network connection. Further security enhancements such as quick erase and military erase are supported.
