Hello, I'm working on a fault-tolerant application and need to establish communi- cations between four separate vme backplanes. The maximum distance between backplanes is ~10 feet. The system in each backplane must be able to sustain simultaneous transfer rates on 4 separate bi-directional channels of at least 200KBytes per second. (8 unidirectonal links at a minimum of 100KBytes per second would be acceptable). I've got at least two and mabye four cpu cards with local memory and some other peripherals in each backplane, so whatever mechanism I use for inter backplane communication cannot hog the bus. Based on the througput requirements, I think I can rule out the generic vme serial i/o cards with zilog scc chips. I think that I could use high speed parallel, scsi, or a transputer board. Has anyone done something similar to this? Can anyone recommend specific boards or another approach? Please reply directly to me and I will summarize if there is sufficient interest. If you do not want your name or response included in my summary, please indicate this fact in your reply.
