What A+B feeds mean
A and B are independent power paths. Dual PSUs on both paths keep services up if one side fails. Tier III continuity during maintenance relies on this architecture.
How to size kW
Prefer measured draw over summed nameplate watts and leave headroom. Dense NUMA, GPUs or disk arrays raise kW quickly.
- Record average and peak consumption
- Add 20–30% growth buffer
- Balance load across A and B where possible
PDU and contract notes
- Choose metered/switched PDUs based on monitoring needs
- Plan hardware within contracted amp/kW limits
- Clarify power upgrade lead times with the NOC early
KuzeyDC colocation power options scale from 0.5 kW to 10 kW+; accurate kW sizing is critical for both SLA and cost.
