DCO 8.2.7, how to setup server power redundancy

DCIM_Support · ‎2020-07-04

Just for clarity please....

in DCO how would you set them up in this scenario?

1x UPS with N+1 redundancy with 2 feeds to PDPM277H style distribution boards with each one feeding an A and B rPDU in the racks. Assume all servers have dual power supplies with 1 feed from rPDU A and 1 feed from rPDU B.

What should the server power settings be setup as?

Distribution Redundancy

N+1

Distribution Redundancy N+1

I await your answers...

Hi Garry,

For this setup (nice illustration) I would use "Distribution Redundancy N+1" settings for server. As described in the following page: What does the power tool tip tell me, this is a combination of "Distribution Redundancy" and "N+1". For this type of redundancy, the power distribution is redundant and there is internal redundancy on the UPS level (one UPS with one redundant power module).

Kind regards

Thanks Jef. I had been previously advised that this would be N+1 because the UPS is N+1. Can't remember the source of this as it was so long ago...

After setting the servers up this way I noted that DCO will not calculate potential failover load so changed some of them to "Distribution Redundancy N+1" and the figures seemed to make more sense.

I am even happier that I was right in what I thought...

Thanks again
