Sgi TezroThe SGI Tezro is the most recently released (as of January, 2005) high-end workstation available from SGI, and is the immediate successor to the SGI Octane. The system is available in both rack-mount and tower versions, and was released in June 2003 with a list price of $20,500. The Tezro was released alongside the SGI Onyx4 - the Onyx4 and rack-mountable Tezro share many components, including skins. Both tower and rack-mountable systems marked the return of the original 'cube' logo to SGI machines, which was welcomed by the loyal user base. Architecture Similar to other SGI systems, the Tezro uses a non-blocking crossbar interconnect to connect all subsystems together. Processors Either 1, 2 or 4 800MHz 64-bit R16000 CPUs are available in both rack-mount and tower systems. Single and dual 700MHz R16000 CPUs versions are also available. Both the 800 and 700MHz CPU's have 4MB of L2 cache. Memory The Tezro ships with 512MB of DDR SDRAMM as standard, with tower versions able to utilise 8GB, and rack-mountable versions 16GB Graphics The high-end Odyssey card, V12, is the only graphics card available. Audio Tower systems ship with analogue audio out as standard, while PCI cards provide audio capabilities on rack-mountable versions, and additional 2-channel 24-bit AES and 8-channel ADAT connectors. Expansion The number of available 64-bit PCI slots depend upon the number of installed CPU's in the system: - 7 133/100MHz slots with 2 and 4 CPU tower systems
- 3 133/100MHz slots with 1 CPU tower systems
- 6 100MHz slots and one 66MHz slot in 4U rackmountable systems
- 2 100MHz slots and one 66MHz slot in 2U rackmountable systems.
All PCI slots in each Tezro model are 3.3V card slots. A single U160 SCSI connector is available for attaching external peripherals, as is an optional FireWire card. Operating System The only operating system capable of running on the Tezro is SGI's IRIX. External links Tezro home page Press release announcing the Tezro Tezro
