H500 Chassis Power Redundancy

Jump to solution

I am looking for documentation about power supply redundancy in the H500 nodes in our chassis. Our chassis has 4 H500 nodes each with a single power supply. We have 2 PDUs in the rack, each on it's own circuit. Nodes 1 and 3 are on PDU A and nodes 2 and 4 are on PDU B. What happens if PDU B loses power?

I assume that power from node 1 would keep node 2 up and node 3 would keep node 4 up. Is that really what happens? Our maintenance department is reworking some power in the data center and they will need to take one PDU down to change circuits. I need to make sure that we do not have an outage while they work on the power.

Gen6 nodes are grouped in pairs and share their power supplies. In each group, one power supply can fail without a node failing. But if the last connected power supply fails, two nodes will fail.
