On a Cisco Catalyst 3000 switch, with the following benefits, what is this called?

Pay-as-you-grow architecture, similar to the data stack (StackWise)

1+N redundancy, as opposed to the existing RPS-based 1 :N redundancy

Efficiency improvements, using the Green Power feature of offlining supplies when there are multiple supplies available and in low load conditions

MTBF improvements, due to improved efficiency, load sharing, and 1+N redundancy

Flexible installations, from requirements for fewer AC outlets (4 x 250 W vs. 1 x 1.0 kW) and "zero footprint" RPS with 1+N power budgeting

Default power-sharing mode
