SGI Origin 350 technical server.

The SGI Origin 350 computer system uses MIPS-based processors. Current models run at 700-1000MHz, with dual or quad CPU configurations available.

A system consists of up to eight CPU "bricks" (2 rackmount units high each) with up to four CPUs in each brick, giving a maximum of 32 CPUs. CPU bricks are connected together via NUMAlink3 cables going to a central NUMAlink router or hub which is another 3U rackmounted unit. Each CPU brick has four PCI slots across two PCI busses. Each CPU brick also has a Fuel-style XIO slot, which can accept a DMediaPro DM3 card or a VPro graphics card. The first CPU brick in a system has a single PCI slot holding an IO9 BaseIO card with SCSI interfaces for two internal disks, an external SCSI port, audio I/O and a twisted pair Ethernet connection.

Other kinds of bricks are available that are dedicated to disk storage or further PCI slots. Multiple bricks are co-ordinated at startup time via an L2 controller which communicates to the bricks via USB ports. The L2 controller is an external PPC Linux unit with console, USB, modem and ethernet ports.
