This chapter describes the GT200 cards, their features and network environments.
2.2 Network Features
The GT200 Network has the following features:
• A ring topology with a maximum network throughput of approximately 205
Megabytes (MBps) (base10).
• All writes to GT200 memory generate network traffic (no filtering occurs based
on current values present in memory).
• Protocol-supported network addressing for 128 MB shared memory for each
node processor.
• Variable-length frame with a maximum pay load of 128 bytes.
• 255-node capacity on each ring.
• No operating or system software is required to support network protocol.
• No network-dependent application software is required.
CAUTION: Check with the host computer manufacturer to find out which slots are
available for third party PCI memory cards before installing the GT200 Network board
into any system. Installing any type of PCI card in a non-standard PCI slot may result in
serious damage to the host machine.
