The following is a basic Overview of the Tezro rackmountable workstation.
Size / Physical
The Tezro workstation consists of either one or two enclosures, each is 2U in height, the first enclosure contains CPU's and the second enclosure is for I/O and memory only.
CPU / Memory
The maximum CPU capacity is 4xR16000 CPU's @ ???MHz (IP53) (CPU's are
only present in the first enclosure)
With one enclosure the maximum memory is 8GB, with two enclosures the
maximum becomes 16GB (no more CPU's can be added with the additional
enclosure)
Disks
The first enclosure can contain two disks, one of which will be the system disk, with a second enclosure and an additional IOC9 card two more internal disks can be added
The disks are connected to an Ultra 160 SCSI bus.
A VHDCI connector is on the back for additional SCSI devices
CD/DVD
There is an internal IDE DVD-ROM in the first enclosure.
Graphics
The Tezro has VPro graphics, however it appears to differ from the Octane VPro graphics in that it appears to support the standard 1280x1024@72/76Hz, the graphics connector is a DVI-I connector with Analog RGB and TMDS video.
Audio
Expansion
PCI: The PCI slots can take 33/66 MHz PCI and 66/100/133MHz PCI-X cards
The main enclosure has two PCI busses with two PCI connectors on each, one of the connectors is used by the IOC9 card.
The expansion enclosure adds an additional two PCI busses, each with two PCI connectors.
The total PCI I/O connectors free are 7, 3 in the first enclosure and 4 in the second expansion enclosure (unless an additional IOC9 card is added to the second enclosure)
NOTE: one (or two if an additional IOC9 card is used) of the PCI connectors share the bus with the IOC9 card - this card needs to be able to run at 66MHz otherwise it will slow down the IOC9, if a faster card is inserted it will be forced down to 66MHz.
