Thank you for your question:
Q: How much redundancy is built into a DSSD D5 / are there any single points of failure?
All hardware components are redundant except for the passive midplane. Dual redundancy is part of the product architecture.
2 X CM, 2 X SM, each survive single component failure, 2 X IOM are redundant if hosts have a connection to each, 2+2 power supplies, survive dual failures, and Cubic RAID survives many failures. 4+1 dual rotor fans survive a single fan module (2 rotor) failure. The midplane is a single nonredundant component but it is passive and should not fail under normal circumstances.
This Ask the Expert event has officially ended, but don't let that retract you from asking more questions. At this point our SMEs are still welcomed to answer and continue the discussion though not required. Here is where we ask our community members to chime in and assist other users if they're able to come up with accurate information.
Many thanks to our SMEs who selflessly made themselves available to answer questions. We also appreciate our community members for taking part of the discussion and ask so many interesting questions.
