Note: The system supports a maximum of 12 memory DIMMs. Memory DIMMs must
be installed in groups of four, and each group of four must be of the same speed and
memory capacity.
Each deskside visualization system is available with 1 or 2 processors. The processors are
available with different clock speeds and cache sizes. Processor upgrades are
accomplished by replacing the entire system node board (which requires a service call by
a trained technician).
For a complete list of available processor, I/O, or graphics upgrades, contact your sales
representative.
The following storage upgrades are available for the system:
• One additional hard disk drive (total internal capacity is two hard drives)
• External SCSI DAT drive
An SGI InfiniteStorage TP900 non-RAID SCSI array is available for optional mass storage
capacity. This unit is normally mounted in a rack.
The system can also be connected by way of a fibre channel PCI option card to a
high-performance storage array, such as the SGI InfinitePerformance TP9700. These disk
arrays offer large storage capacities in RAID configurations.
In addition to the items listed above, there are a variety of other storage solutions
available from SGI. For more information, contact your SGI sales representative.
