Anyone have any pictures, datasheets, or other ephemera related to Sequoia Systems line of fault tolerant systems?
This is unrelated to the "IBM Sequoia". The Sequoia computers I'm referring to were around roughly '86+ish maybe and were fairly large minicomputers. Their claim to fame was being "massively fault tolerant". I am not sure, but Ian Sandler may have worked there on that design before heading to General Automation perhaps, not sure I have my history right. What I do recall for sure, is I worked on a lot of programming on the Sequoia systems (the ones I used ran Pick or one of the MVRDBMS's) at Eagle Snacks (back when that was part of the Anheuser-Busch family). On a whim I decided to google and while I can find a few white papers on the Sequoia Fault Tolerance design, I see no marketing brochures, datasheets, pictures, etc. I do recall a story from back when I worked there. the head of eagle snacks was called into the office of the VP of AB for a dressing down, because all the other departments submitted downtime reports to him on their systems and Eagle Snacks (running on the Sequoia) did not submit any reports for over a year. When asked why he wasn't submitting downtime reports the eagle snacks guy replied "because we haven't had any". The VP said - yes, but I see here maintenance logs that you had cpu boards failed and replaced, memory boards failed and replaced, "etc etc". and the ES guy said "Right. No downtime". Anyone remember these systems? Best, J
