The Silicon Graphics Tezro (styled as silicon graphics tezro) is a high-end workstation introduced by Silicon Graphics in 2003 to replace the Octane 2. Built on the Chimera architecture, the Tezro is closely related to the Origin 350 and Onyx 350 systems offered by SGI during the same time period and shares the graphics module, node boards, drive sleds and some cooling parts. The Tezro is essentially a single-node Onyx 350 mounted on its side and connected like a sandwich to the IO backplane. The system was succeeded late in 2006 to early 2007 with the launch of the Prism. The Tezro is highly sought after in the collector market for its style, power, and the distinction of being among the last MIPS workstations produced.

Summary

The Tezro is the last in the line of high-end, MIPS-based, workstations produced by Silicon Graphics. It is the largest and heaviest of the workstations produced and shares many parts with the rackmount Origin and Onyx 350 including graphics, node board (Which holds the CPUs and memory) and memory. By this time, Silicon Graphics had fallen behind many of its competitors in performance, and thus the Tezro did not sell as well as anticipated and continues to hold its value on the secondhand market.

Configurations

The Tezro is powered by the MIPS R16000 series of processors and came in dual and quad CPU node boards. The CPUs are attached to the node board, thus a configuration upgrade required removal of the entire node board.

L2 Cache: Dual (MHz): Quad (MHz):
4MB 700; 800 700; 800
8MB 700; 800 700; 800
16MB 1000 1000

The Tezro shipped with between 512MB and 8GB of DDR RAM - and can be expanded to a maximum of 8GB.

A maximum of two 300GB U160 SCSI drives can be added to the system via the front access panel using the Origin/Onyx 350-style sleds.

Tezro supports the V10 and V12 graphics options. Dual-channel options were produced, allowing up to two 1920x1200 displays.

Form Factor and Transportation

The Tezro measures 21 x 14 x 17 inches in L x W x H dimensions and weighs at minimum 61lbs, more if it is heavily equipped. The front access panel is very fragile, and the system should not be held by the plastics as they grow brittle with age.

The unit has wheels on the rear, allowing for easy movement on hard surfaces. It should be carried gently and preferably with the rear of the unit supporting the weight, not the sides or the front.

Collectibility

The Tezro maintains a market value between $700 to over $2000 USD, depending on configuration.

Shipping the Tezro is expensive. It needs at minimum 5 layers of plastic bubble wrap, styrofoam protection and considerable reinforcement to survive shipment.
