After releasing the Origin3000 series in July 2000, it was expected that at some point SGI would produce a workstation based on the O3K architecture. Sure enough, in January 2002 the Fuel workstation was announced, offering 500MHz and 600MHz CPU options at launch.
Fuel is a effectively a single-CPU Origin3000 with VPro graphics - the same graphics technology used in Octane2, though Fuel's faster architecture can get more out of the graphics subsystem just as the later multi-CPU O3K-based Tezro workstation can. For background information on how Fuel works, see my Origin3000 guide.
When Fuel launched, some assumed it was to be regarded as a new low-end desktop to replace O2, but that was not what SGI had in mind at all (SGI never released a new low-end desktop after O2). Instead, I was told, many customers wanted a performance desktop solution that did not require them to pay for the expense of having multi-CPU support which they didn't need. Fuel plugged this gap and was thus 35% cheaper than Octane at launch.
Alas, SGI did make some mistakes, some of which can be debated but others are certain. Fuel's maximum RAM is 4GB, which is not really high enough for some tasks. Customers who would have been happy with a single-CPU system nevertheless often needed a lot of RAM, eg. processing with ANSYS, or as an entry Flame/Smoke system. Fuel should have supported 8GB or preferably 16GB. Likewise, the lack of built-in Gbit ethernet and audio was an odd decision.
However, Fuel did sell quite well; today it is one of the most popular hobbyist choices due to it's more expansive support of DVD, USB and Firewire devices compared to O2 or Octane, the fact that it's a much faster system in many ways (all the speed advantages over Octane described here also apply to Tezro of course) and its lower cost compared to an Octane with the nearest equivalent CPU/gfx options. Fuel has 4X faster SCSI than Octane (U160 instead of UW, with U320 optional via LSI PCI cards), 2X faster 66MHz PCI (4 slots on 2 buses built-in as standard!), 2X faster RAM, 2X faster system/RAM bandwidth, better RAM latency (ie. faster access time) and produces less noise.
Here are the available CPU options for Fuel:
A slight claim to fame btw - it was my moaning to the admin of sgi.com and his help in nagging SGI PR that in May 2006 led to the SGI marketing department finally allowing the web site to mention both the 1GHz CPU for Tezro and the 900MHz CPU for Fuel, though some of the PDFs have still not been updated. For reasons unknown, SGI never publicised these CPU options. My thanks to David Kascht at SGI for his assistance.
Fuel has four DIMM slots (2 banks of 2 slots each), minimum 512MB, maximum 4GB, using the same DIMMs found in Tezro and Origin300/3000. Most Fuels on the 2nd-hand market have 1GB RAM using one bank. There is a price premium for 2GB kits, but it's usually not too bad.
Audio is not included as standard in Fuel. An M-Audio Revolution 7.1 PCI card is the best audio board to look for, though this card is expensive even 2nd-hand. A cheaper alternative is the SoundBlaster Audigy2 ZS; the quality is not as good, but it does the job.
Unlike Octane, Fuel supports Firewire and USB to some extent, so one can use a USB device (Griffin imic or Telex USB audio device) to provide audio if the PCI options are not available. A more recent version of IRIX is essential though for using USB devices (I recommend 6.5.28 or later; 6.5.17 was the first IRIX version for Fuel, but that is far too old to properly support USB/Firewire devices).
For professional audio, one can use the RAD Audio PCI card which provides eight ADAT optical audio channels, but it must be the 3.3V version of the card (SGI PN 030-1441-001 or 030-1649-001), as opposed to the 5V version for Octane which is PN 030-0950-002 (make sure you find the right model).
Internal Storage/Media Expansion
DVD devices work better with Fuel than Octane. Fuel has two internal 5.25" bays included, with a DVDROM typically already installed in most systems (usually a Toshiba SD-M1401, though the SD-M1711 is better if you can find one), but not always. A CDRW or CDROM is also possible, or a DAT drive (Sony SDT11000 DDS4 works very nicely, though older models will work fine aswell). Here is a speed comparison of the 1401 vs the 1711, copying a single 1GB file to disk from a DVDR, and copying a CD with 667MB of data (1207 files) to disk:
DVDR Copy CD Copy m:ss.ss m:ss.ss Toshiba SD-M1711: 4:49.23 3:07.02 Toshiba SD-M1401: 6:25.09 3:15.17
Various models of IDE DVDRW drives also work ok when connected via a Yamaha SCSI/IDE adapter (full details at the excellent Fuel Hardware Aggregator on Nekochan), but again this does require a recent version of IRIX and up-to-date Nekoware apps for best usage. The system has space for three internal 3.5" disks, though one could always employ the 5.25" bays aswell if required.
Fuel can also use various FibreChannel (FC) and certain SAS/SATA PCI cards, so one could use FC, SAS or SATA drives aswell, though the PCI cards are not visible to the PROM during power-on so such devices could not be used as a system disk. However, a setup such as a 147GB 15K system disk plus a 1TB SATA option disk is perfectly possible.
Here is an example diskperf result on a 36GB 15K disk in a 600MHz Fuel:
# req_size fwd_wt fwd_rd bwd_wt bwd_rd rnd_wt rnd_rd # (bytes) (MB/s) (MB/s) (MB/s) (MB/s) (MB/s) (MB/s) #--------------------------------------------------------- 16384 52.24 59.79 44.27 22.78 7.83 4.33 32768 71.53 83.55 63.22 29.89 15.99 8.23 65536 85.37 97.17 72.86 33.94 25.94 14.63 131072 90.45 97.41 76.38 39.27 36.07 24.34 262144 93.92 97.67 73.13 53.03 49.27 38.13 524288 93.84 52.34 81.29 53.06 60.66 52.60 1048576 93.99 66.18 84.41 68.87 69.63 64.74 2097152 94.12 78.18 79.26 78.20 77.12 74.34 4194304 94.33 85.46 86.43 85.77 85.41 83.87
Easily 3X faster than the typical speeds possible with Octane's internal UW bus. Octane can have faster speeds, via the use of a suitable SCSI option card in a PCI cage or XTalk, but this can be expensive to setup.
Even a 10K drive runs faster in Fuel compared to Octane though, eg. here is a diskperf test on a 36GB 10K:
# req_size fwd_wt fwd_rd bwd_wt bwd_rd rnd_wt rnd_rd # (bytes) (MB/s) (MB/s) (MB/s) (MB/s) (MB/s) (MB/s) #--------------------------------------------------------- 16384 53.74 53.95 13.43 2.87 5.62 3.12 32768 54.51 54.27 19.85 6.06 10.37 5.71 65536 54.52 54.27 27.68 13.49 16.69 10.29 131072 54.11 54.02 36.31 27.07 24.59 17.19 262144 54.45 54.30 41.11 36.48 33.27 25.76 524288 54.26 54.02 40.06 36.57 38.50 34.58 1048576 54.23 54.27 46.33 41.72 43.23 39.56 2097152 54.09 54.35 47.77 46.30 48.43 44.55 4194304 54.07 53.77 52.20 49.66 51.13 48.35
Where Fuel really shines is access time, benefiting greatly from the 15K rpm disk speed. Octane does benefit aswell from a 15K drive, but not as much as Fuel can. For example, I tested how fast a 500MHz Fuel is able to search all of /usr/share for a deliberately non-existent file, thus forcing the search to examine the whole of /usr/share, some 715MB of data (more than 54000 files):
Search Time (seconds) 36GB 15K: 11.08 36GB 10K: 18.32
ie. about 40% faster. I find these shorter search times especially useful as I often have to hunt for something in my email archive.
Note that I do have various 15K drives available, discount for Neko members! Email for details.
Fuel has four PCI64 slots: two at 66MHz and two at 33MHz (the faster slots are nearer the base of the system). PCI with Octane requires either the expensive PCI cage or an XTalk adapter, so Fuel has a major advantage here. My own Fuel has an LSI U320 dual-channel card, QLA12160/66 card, SGI Gbit card and a Revolution 7.1 audio card. Octane does have one small advantage in that in theory it can hold up to six PCI cards (five for systems with VPro gfx), but Octane loses on speed since Fuel can drive two of its PCI slots at 66MHz, vs. 33MHz for all possible Octane PCI configurations.
Fuel supports a wide range of PCI option cards, including QLOGIC and LSI U160/U320 cards, an LSI SAS/SATA card, various FC cards, Gbit Ethernet, audio, serial, USB and firewire options. Here is a list, courtesy of the the Nekochan hardware summary and my own information. Each line has an identifier name to denote the type of card. Any item that is suspected to work but not yet confirmed is shown in italics.

Fuel does not support any XIO options.
The only available options are V10 and V12 - the same VPro technology as used in Octane2, but they use a physically different form factor. The connector is DVI, as opposed to 13W3 on Octane. One can use a DVI/VGA adapter or cable to connect to a monitor or flat panel. For connection to an older monitor with a 13W3 socket, DVI/13W3 cables do exist but they are hard to find - it's easier to use a VGA/13W3 adapter and then either a VGA/DVI cable or VGA cable + VGA/DVI adapter.
V10 has 32MB combined RAM, V12 has 128MB. I've often seen it said that V10 allows up to 8MB for textures while V12 can have up to 108MB for textures, but this is not true. If one uses 1280x1024 with 8 bytes per pixel, then V10 provides 20MB for textures and V12 offers 120MB. Both options are the same speed, but V12 supports a much wider range of display resolutions (hobbyists have created numerous extra video format files to support LCD/TFT displays, eg. 1680x1050 @ 60Hz).
One can use a dual-channel display card to drive two monitors or LCD/displays.
The DMediaPro DM6 supports uncompressed standard definition serial digital video in both PAL and NTSC formats. Sadly this PCI-based option board is hard to find.
Fuel makes less noise than Octane, which is good, but even so there are those who replace the fans with modern low-noise versions to reduce the noise level even further.
Under load, a typical Fuel uses about 200, with a higher spec model draining around 230W. My Fuel, which is utterly maxed-out, uses 281W under load, 259W idle.
One issue with Fuel that has plagued some people is dealing with earlier revisions of the motherboard which have bad environmental monitoring ICs. Turning the monitoring off is one solution, but see the Nekochan thread for full details on this issue and how to replace the ICs if required. In general, later models of Fuel will not suffer from this problem.
Build Style and Appearance
Fuel resembles a PC-style tower unit, with a removeable side panel for access to all internal components. A front flap opens to reveal the two internal 5.25" bays, power button and recessed reset button (these pics are of my own system, showing a Yamaha 16/10/40 CDRW and Toshiba SD-M1711 DVDROM). As with any PC-type tower unit, the rear of the unit presents the keyboard/mouse ports, serial ports, parallel, ethernet, USB, monitor output and PCI slots. Here is a close-up of the PCI slots of my own system, taken at a point before my scanner was connected to the remaining U160 SCSI port.
The cage for holding two internal disks rotates outwards (this image shows my system's 147GB 15K system disk and 300GB 10K data disk), while the large blue cover over the motherboard/fan lifts up easily to give access to the RAM slots. The front panal is removed by gently lifting the tabs on the left side of the panel while pulling the panel away from the chassis. Internal 5.25" devices are attached to rail guides, allowing them to slide out for removal. A bracing bar across the system adds strength, but is easily removed by extracting a single screw (swapping out the motherboard is not particularly difficult).
Fuel was SGI's first desktop system with any significant degree of internal cabling, quite unlike Octane which has almost no cables inside at all. As a result, some hobbyists are not that keen on Fuel's design, but they forget that this deliberately lower-cost build is partly why Fuel was so much cheaper than Octane when first launched. Besides, the flat top of the unit is definitely useful for positioning external devices, and I personally do like the fact that removing the side panel is much less likely to cause any accidental damage to internal parts - contrast this with Octane, where removing the motherboard or gfx assembly can all too easily lead to problems with dust getting on the XIO connector, etc. Swapping the motherboard in Octane is certainly easy, but risky if not done correctly. Likewise, a Fuel graphics board has an edge connector that is more like a PCI card and so is far less likely to come to harm during handling.
For raw speed, a 500MHz Fuel can be 40% faster than a 400MHz Octane2 with a good disk, ie. a better speed increase than is implied merely by the 25% higher clock speed, eg. application startup times for Firefox, OpenOffice, etc. are much better. Fuel can take good advantage of a 15K rpm drive since it has U160 SCSI, eg. 98MB/sec is possible with a nice 15K, more if using XLV stripes, etc.
Although the graphics option can only be a single V10 or V12 VPro, Fuel can get more out of them compared to the same options in Octane, though one would probably only notice this if working with more dynamic datasets or other complex models. Overall, for any basic single-CPU/gfx combination, Fuel is better value for money than Octane2; in other words (for example), a 600MHz Fuel V10 is cheaper than a 600MHz Octane2 V10. Lower-spec Octanes are cheaper, eg. 400/V6, but V6/V8 have resolution restrictions which are absent on V10/V12. I used a 550MHz Octane2 as my main desktop for a long time, but finally switched to Fuel because of the extra responsiveness for heavy applications like Firefox, and the ability to do things like search my email archive at much greater speeds than is possible with Octane.
If you can make good use of dual-CPUs, then Octane2 may be a better though more expensive choice, eg. for use with Blender, Maya, Alias, SoftImage, or other professional applications, but Fuel quickly displays an advantage as the task becomes more complex, eg. my tests show that, for rendering complex scenes in Alias, a 600MHz Fuel is only a little slower than a dual-400 Octane, though it depends on the scene complexity. For a simple Maya scene rendered via mentalray, a dual-CPU Octane scales perfectly, ie. no real gain from the faster O3K architecture in Fuel (thus, a dual-R10K/250 Octane is a good low-cost solution). Likewise, a dual-600 Origin300 is about the same as a dual-600 Octane for simple scenes, but is significantly faster for complex scenes. Given Fuel's low cost though, animation rendering under IRIX is probably best served via multiple 500MHz or 600MHz Fuels or Origin300s instead of expensive dual-CPU Octanes, the exception being dual-250 Octanes for strictly simple scenes. For interactive work, Fuel's faster SCSI means better loading and saving times for large files aswell.
Thus, if single-threaded speed is more important (ie. running applications such as OpenOffice or Firefox), then a 500MHz or 600MHz Fuel with a 15K disk is a good system (I recommend the Maxtor Atlas 15K II), though it's wise to get a system with audio if possible since Fuel does not have built-in audio.
I was once asked about what the best choice was for a performance IRIX solution for animation modelling and rendering. Due to the high cost of good dual-CPU options for Octane, and the similar high cost of 700MHz or higher CPUs for Fuel, I recommended a combination of a Fuel for modelling and an Origin300 for rendering; this would be cheaper, faster and more flexible than a dual-600 Octane2 V12.
The faster SCSI subsystem has one other useful consequence, namely better network transfer speeds when using Gbit connections. My Fuel is able to sustain more than 65MB/sec when transfering files via ftp to/from another Gbit-equipped system such as Tezro or my PC. By contrast, unless a better SCSI system is added via a PCI cage or XTalk adapter, Octane cannot sustain more than about 37MB/sec across a Gbit link because of the limit of the UW SCSI bus. Octane can of course use FC cards, including a dual-port copper XIO FC card, but FC is somewhat more complex to deal with than SCSI, and Fuel has an advantage here anyway since Fuel's faster PCI means it can properly exploit higher bandwidth FC options such as the QLA2342.
Does not mention the 900MHz CPU. Here is the original version from Jan 2002 which only mentions the initial 500MHz and 600MHz CPU options.

According to Reinhard, a disabled 2nd bank should always allow for booting provided the first bank is populated. If a node exception occurs though, then the PIMM is probably bad.

Schleusel's comments on the fan replacements:
Initially I had no intention to replace the large Exhaust fan as it was barely running at half speed most of the time - but as soon as I had replaced the rest I realised the very annoying clatter it produced. If your's is quiet - don't replace it.
The Titan fan I now have in there isn't really optimal as it is only a 25mm thick model. It needs a higher rpm to move the same amount of air (currently its running at ~1500 rpm compared to the ~1200 rpm the original was mostly running at) but its still a lot more pleasent than the old one. It seems to be pretty hard to find 120x120x38mm fans these days.. well, apart from some 30 EUR+ PAPST models.
A note on the PSU fan:
I have the first generation 430W PSU so I can't comment on the newer 480W ones. The PSU fan was by far the noisiest part in the system. Noname thing running at 3400rpm and no rpm sensor (two pin only). The L1 controller does somehow manage to "guess" its rpm but it isn't really controlled. A few minutes after the machine is powered on it just keeps running at peak rpm. Initially I replaced it with a YS-TECH at 3000 rpm that actually moved more air than the original one - and was almost as annoying As the PSU is hardly running at 50% load and barely got hot I decided to try the PAPST I currently have in there. 19% less throughput at 2600 rpm - a lot better. Some Silent PC junkie would probably still run away but I don't really dare to go even lower.
It needed a little software hack though: When initially powered on, the PAPST is running below the warning rpm of the L1 environmental monitoring. So with the monitoring running the L1 would just switch off the machine 60 seconds after power on. To work arount that I wrote an init script that switches off the env monitoring during system shutdown and switches it on again 5 minutes after the system is booted. At that time the PAPST is already running at full rpm and the L1 is happy - very ugly but works.
Anyway, a newer PSU is still quite high on my wishlist. Several l1cmd env outputs of machines with 480W PSU show the stock fan running way slower than my original one.. and hopefully with proper rpm sensor as the rest of the fans too."

Recommended CRT Monitor List
Not directly related to Fuel, but I thought I would include here the results of my search for monitors that support up to 2048 x 1536, the same max resolution of the SGI GDM5411. My 5411 died, so I replaced it with a Dell P1130. I was very pleased with the P1130 and so I then replaced my two ageing GDM20E21s with two HP P1130s. The P1130 is an excellent monitor, highly recommended.

Some of these monitors use exactly the same tube, just with different case colours, styles and control button locations.
