PredecessorSGI Origin 2000

The SGI Origin 3000 series is a family of modular servers made by Silicon Graphics, built from rack-mounted "bricks" that each do one job: C-bricks hold processors and memory, I-, P- and X-bricks provide I/O, R-bricks route the NUMAlink 3 interconnect between C-bricks, D-bricks hold disks, and a power bay supplies them all.[7] SGI sold it as the Origin 3200, with up to 8 processors in a 17U short rack; the Origin 3400, with up to 32 processors in a 39U tall rack; and the Origin 3800, with 16 to 512 processors in two or more tall racks.[7] It succeeded the SGI Origin 2000, and with graphics bricks added the same system becomes the SGI Onyx 3000.[7][1] The SGI Origin 300 is an entry-level server built on the same architecture.[1]

History

[edit | edit source]

SGI introduced the Origin 3000 and Onyx 3000 in July 2000 to succeed the Origin 2000 and Onyx2.[1] The sgistuff.net hardware pages, a community reference, record 500 MHz R14000 processors in May 2001, 600 MHz R14000A in February 2002, the denser Origin 3900 in November 2002, an 800 MHz processor upgrade announced in October 2003 together with the end of production of the Origin 3200 and 3800 on 31 March 2004, and the end of production of the Origin 3900, announced in July 2006, with last shipments in March 2007.[2] Wikipedia gives the Altix 3000 as its successor in 2004 and 29 December 2006 as the discontinuation of the last model.[1]

C-brick

[edit | edit source]

The IP35 motherboard carries the L1 controller logic, the Bedrock ASIC, eight DIMM slots for 512 MB to 8 GB, a serial ID EEPROM and three 2.5 V, 30 A VRMs that make the board's voltages from the 48 V supply. The processors sit in pairs on one or two processor integrated memory modules (PIMMs), each processor with 8 MB of secondary cache.[8] Memory goes in two DIMMs at a time; the standard DIMMs serve systems of up to 128 processors and the "premium" DIMMs, with extra directory memory, larger ones. The DIMMs do not fit the Origin 200, Origin 2000, Onyx2 or Octane.[8] The C-brick's LINK connector joins it to an R-brick (or directly to a second C-brick in an Origin 3200) at 1.6 GB/s each way, and its XIO connector to an I/O brick at 1.2 GB/s each way.[8]

Power

[edit | edit source]

The power bay holds three to six hot-swappable supplies, each taking single-phase 200-240 V AC and delivering 950 W at 48 V DC to a common bus; the bay feeds the bricks through eight output connectors and also supplies a 12 V standby voltage that runs each brick's L1 controller. The VRMs and DC-to-DC converters in each brick make the lower voltages from the 48 V.[5] The supplies run N+1, so the loss of one leaves enough power for the system.[5] D-bricks have their own 220 V supplies.[5] SGI reserved the power bay and its supplies for its own engineers.[5]

Cooling

[edit | edit source]

Air flows from front to rear. Each brick has three front fans, and the R-brick two smaller single-speed ones. The L1 controller varies the fan speed with temperature; the fans are N+1, and if one fails the others speed up and an error is reported.[7] Each power supply has two fans of its own.[5]

System control

[edit | edit source]

Every C-, I-, P-, X- and R-brick has an L1 controller with a display on its front panel. Tall racks with C-bricks have an L2 controller with a touch display on the front door; on the Origin 3200 it is optional.[7] The L1 controllers monitor power and temperature and shut bricks down to prevent overheating.[7]
