We're looking at power options for a z890 in a backup datacenter. The Installation and Planning manual says that the z890 can run off either
single phase or three phase power. The site cost for a three phase suppl y is more than the cost for a single phase supply. I understand what singl e and three phase power are (thanks Google), I just don't understand, and havn't been able to find, what the trade-offs/compromises are other than the cost. This leaves me unable to evaluate the cost benefit of 3 phase vs 1 phase, and hence make a recommendation. Any help would be appreciated. Reference to source material would be great. Brian Nielsen
