Hi,

I have a question about redundant power supplies on servers.  I think I had a dell, which if the primary ps died, the other took over.  I think on my DL 380 G5 the two ps are both live, so if one looses power, the other if it is getting power keeps the server on.

When buying equipment that talks about redundant ps, is there a way to know which is being referred to - if the primary ps has to die for a switch over vs if both are looking for power all the time, and if either one gets power you are good.

As for the later description, it would work if both ps were plugged into different ups and one ups died, whereas in the ps fail over only method, if the primary ps is plugged into the ups that dies, the server goes down, because it senses that ps is fine, it just doesn't have power so no switch to the second ps ever happens.

Thanks,
gsgi
