In-Row Cooling - how to provision for redundancy?

[karbonphiber_apc]

How would one provision for air distribution redundancy when designing a data center with in-row cooling? The problem that I am stuck with is if I have an in-row rc failure at either end of the row, how does cool air now get to those racks?

You can build additional RC's into the solution. IE

RACK | RC | RC | RACK | RACK | RC | RC | RACK

RACK | RC | RC | RACK | RACK | RC | RC | RACK

Would you be building these RC's into a enclosed Hotaisle?

no HACS. Having redundant RCs at either end, as you have shown looks like a feasible way to do it.

Any thoughts on using a perimeter downflow crac unit with perf panels that have slide dampers to control air flow distribution for backing up my RC's?
