#Mb dexture series

The Octane series has single and dual CPU modules.

The Octane uses ARCS boot firmware, like all contemporary SGI computer systems. This bridging includes the system board (for the IOC3 multi-I/O chip, two ISP1040B SCSI controllers and RAD1 audio), MENET cards (four IOC3s) and the PCI cage (used for PCI cards in Octane). The XIO can be bridged to PCI-X, using a chip named BRIDGE. This makes it very similar to a single node of the Origin 200 system. One of the ports is used for the processor and memory subsystem, one is available for PCI-X expansion, and four are XIO slots (packet-based high-bandwidth bus, somewhat similar to HyperTransport). Xtalk does not use a system bus, but a Crossbow application-specific integrated circuit (ASIC), referred to as Xbow, a dynamic crossbar switch that connects the XIO ports to the hub. The Octane's system board is designated as IP30, based on SGI's Xtalk architecture. It is a series of Intel based deskside systems, as a Xeon-based workstation with 1 or 2 3U EATX trays, or as cluster servers with 10 system trays configured with up to 10 Twin Blade nodes or 20 Intel ATOM MINI-ITX nodes. Octane III was introduced in early 2010 after SGI's bankruptcy reorganization. Support for the Octane2 ceased in June 2009. SGI withdrew the Octane2 from the price book on May 26, 2004, and ceased Octane2 production on June 25, 2004. The Octane is the direct successor to the Indigo2, and was succeeded by the Tezro, and its immediate sibling is the O2. The codenames for the Octane and Octane2 are 'Racer' and 'Speedracer' respectively. Later revisions of the Octane include some of the improvements introduced in the Octane2. The Octane2 has VPro graphics and supports all the VPro cards. The Octane2 has four improvements: a revised power supply, system board, and Xbow ASIC. Newer Octanes are based on the R12000 and R14000. Octane and Octane2 are two-way multiprocessing-capable workstations, originally based on the MIPS Technologies R10000 microprocessor. Octane series of IRIX workstations was developed and sold by SGI in the 2000s.
