years ago 1992 discontinued 1997 1997 operating system irix cpu mips architecture memory 16 mb 1 gb predecessor sgi indigo successor sgi octane website sgi com sgi indigo2 impact and a promotional sgi espresso machine in an indigo case indigo2 impact r10000 the sgi indigo2 stylized as indigo 2 and the sgi challenge m are unix workstations which were designed and sold by sgi from 1992 to 1997 the indigo2 code named fullhouse is a desktop workstation the challenge m is a server which differs from the indigo2 only by a slightly differently colored and badged case and the absence of graphics and sound hardware both systems are based on the mips processors with eisa bus and sgi proprietary gio64 expansion bus via a riser card the indigo preceded the indigo2 which is succeeded by the octane contents 1 overview 1 1 cpu 1 2 ram 1 3 storage 1 4 networking 1 5 graphics 2 sgi timeline 3 references 4 external links overview edit indigo2 desktop workstations have two models the teal indigo2 and the purple impact model both have identical looking cases except color and sub model case badging the available cpu types the amount of ram and graphics capabilities depend on the model or sub model variation there is a special version of the teal indigo2 called power indigo2 with increased fpu floating point unit capabilities and specially designed r8000 cpus the later impact indigo2 workstation model gives more computational and visualization power especially due to the introduction of r10000 series risc cpu and impact graphics cpu edit all indigo2 models use one of four distinct mips cpu variants the 100 to 250 mhz mips r4000 and r4400 and the quantum effect devices r4600 ip22 mainboard the 75 mhz mips r8000 ip26 mainboard and the 175 to 195 mhz r10000 ip28 mainboard which are featured in the last produced indigo2 model the impact10000 each microprocessor family differs in clock frequency primary and secondary cache capacity ram edit all sgi indigo2 models have 12 simm slots on the motherboard the indigo2 uses standard 36 bit parity 72 pin fast page mode simm memory the memory modules are seated in groups of four indigo2 could be expanded to a thermal specification maximum of either 384 mb or 512 mb ram the design of the memory control logic in r10000 machines support up to 1 gb ram but the thermal output of older generation of dram chips necessitate the 512 mb limit with newer higher density and smaller scale modules 768 mb is easily within heat output specifications later 128 mb modules allow the full 1 gb with eight out of twelve sockets occupied storage edit all indigo2 models can accommodate two 3 5 scsi disk drives and one 5 25 scsi cd rom drive inside bays on the front of the machine using specially designed indigo2 drive sleds with proprietary connectors all three drive bays are easily accessed when removing the indigo2 front bezel the internal scsi bus speed of the indigo2 is about 10 mb s the typical hard disks are narrow scsi 1 5200rpm and 7200rpm drives all of the indigo2 drive sleds have a 50 pin female scsi 1 connector and standard 4 pin power connector advanced u160 and u320 scsi disk drives can also be used but then one needs appropriate adapters 80 68 pin to 50 pin scsi networking edit 10mbit on board lan interface 100mbit lan options were made by third parties either via eisa or gio64 expansion cards the two most known and widely used indigo2 network cards are the 3com 3c597 tx 100mbit eisa and the phobos g160 gio64 the second one offers better overall performance due to using the superior gio64 bus which also has the effect of reducing the cpu utilization due to dma transfers graphics edit the graphics options available for the indigo2 can be divided in two groups the pre impact and the mgras impact boards pre impact options consist of the following options indigo2 xl24 indigo2 xz elan and extreme these options are based on the same express graphics architecture from the original sgi indigo but feature improved performance the indigo2 xz was launched in august 1993 at 25 500 equivalent to 47 800 in 2021 and the indigo2 xl was launched in third quarter 1993 at 18 000 equivalent to 33 800 in 2021 1 the mgras impact or just impact family include the solid impact high impact high impact aa and the maximum impact these newer boards have a different architecture than the earlier designs physically they appear to be similar to the older graphics options the low end solid impact board takes up a single gio 64 slot the mid range high impact takes up two gio 64 slots and the high end maximum impact occupies three the high impact and solid impact boards provide the same performance for non textured tasks while the maximum impact provides double the performance the high impact aa option has the geometry performance of a maximum impact but is otherwise the same as the high impact including the pixel fill performance the impact graphics is the first desktop graphics system from sgi to offer texture mapping acceleration though only the high impact and maximum impact had this capability and comes with 1 mb of texture memory as standard the solid impact card is named solid due to its applications for solid non textured modeling when expanded by adding a tram texture ram module to the board the amount of texture memory can be increased to 4 mb maximum impact graphics require two of these modules due its two pixel units although this does not upgrade them to 8 mb with the two modules merely working in parallel to render twice as fast of all contemporaries maximum impact graphics is the world s fastest desktop visualization solution a maximum impact with 4 mb of texture memory and the correct graphics settings can play the first three of the quake video game series with acceptable frame rates all graphics options for indigo2 use the standard 13w3 connector for connecting the monitor and another connector for 3d stereoscopic glasses it is possible to have a dual head indigo2 by merely adding another solid impact card valid configurations include solid solid solid high solid maximum although there are four gio 64 slots available and the high impact takes up two it is not possible to have a high high configuration the impact boards draw more power than the gio 64 bus can deliver so impact ready systems have additional power connectors on the expansion riser card with a separate connection to the power supply an impact ready indigo2 must have an impact ready riser card an impact ready power supply and a sufficiently recent prom revision the indigo2 s
