Using RLUs to Determine In-Feed Capacities
In-feed capacities are the grand totals of the power, cooling, physical space, weight, and bandwidth you will need to support a given number of racks. Let's say you plan to build a data center with 40 Sun Fire 6800 servers (RLU-C). Each Sun Fire 6800 server will have four Sun StorEdge racks (RLU Superset-A) connected to it. That's 40 RLU-Cs and 160 RLU Superset-As.
The following table shows the total floor load support and in-feed requirements for these RLUs.
| Specifications | 40 RLU-C Racks | 160 RLU Superset-A Racks | Totals |
|---|---|---|---|
| Weight | 40,000 lbs (18,144 kg) | 155,200 lbs (70,398 kg) | 195,200 lbs (88,542 kg) |
| Power | 160 30Amp 208V L6-30R outlets
RM=2 339,506 W × RM = 679,012 W |
