Grid Redundancy

In Grid Redundancy mode with six PSUs, all six PSUs are active. The three PSUs on the left must connect to one input power grid, while the three PSUs on the right connect to another power grid.

  • CAUTION: To avoid a system failure and for Grid Redundancy to work effectively, there must be a balanced set of PSU properly cabled to separate grids.

If one grid fails, the PSUs on the functioning grid take over without interruption to the servers or infrastructure.

  • CAUTION: In Grid redundancy mode, you must have balanced sets of PSUs (at least one PSU in each grid). If this condition is not met, Grid redundancy may not be possible.
