Sgi Fuel Overview The SGI O2's direct successor was the SGI Fuel, a high-end workstation primarily based around a single R14000 MIPS CPU. SGI introduced the Fuel in January 2002 with a list price of US$11,495. It's larger sibling is the SGI Tezro. Architecture The Fuel is based around the same architecture as the high-end servers of its time, the SGI Origin 3000-class servers. It shares many of the same features and uses the same components. That is, the Fuel is essentially a single-node, single CPU SGI Origin 3000, which can make purchasing individual components expensive. Processors The SGI Fuel was available with a R14000 and or a R16000 processor running at speeds between 500 and 700 MHz, with a front side bus (FSB) speed of 200 MHz. Memory The Fuel came standard with 512 megabytes of proprietary DDR SDRAM. It is upgradable to a maximum of four gigabytes via two memory banks (four slots). Graphics The Fuel shipped with the then-latest VPro graphics options, the V10 and V12's. Audio The Fuel is capable of outputting 2-channel 16-bit analogue stereo, 2-channel, 24-bit AES audio, and 8-channel 24-bit ADAT digital optical. Speakers may be attached via USB. Additional audio options are available using PCI expansion cards. Expansion Four 64-bit 3.3V PCI slots are available for expansion, two of which run at 33 MHz and two of which run at 66 MHz. The system also has two internal U160 SCSI busses, with space for two internal 5.25" devices and three internal hard disks. Although this machine was the first to support USB connections in IRIX, only audio and HID USB devices are supported. Operating System The SGI Fuel is only officially capable of running SGI's IRIX operating system. External links Fuel
