Traditional Dual PDU Solution vs. Eaton ATS Solution
Provide redundant power to a rack that has clustered 1U servers.
Traditional Dual |
Eaton |
The Eaton Advantage |
|---|---|---|
| Two 3-phase rack PDUs feed single-phase 208V loads | 3-phase rack ATS feeds single-phase 208V loads |
|
| Two power supplies per server | One power supply per server; the Eaton ATS provides redundant power to each server power supply, so a second power supply is not required |
|
| Two power cords per server | One power cord per server |
|
The Eaton ATS can also provide redundant power to a single-cord top-of-rack switch, eliminating the need to purchase a separate ATS dedicated to the switch. (1) The estimated efficiency gain assumes 80 PLUS® certified power supplies, with dual power supplies loaded at 25% compared to single power supplies loaded at 50%.
