Talk Title: "A Hybrid

Electrical/Optical Switch Architecture for Modular Data Centers"


The basic building block of ever larger data centers has shifte

d from a rack to a modular container with hundreds or even thousands of ser

vers. Delivering scalable bandwidth among such containers is a challenge. A
number of recent efforts promise full bisection bandwidth between all serv

ers, though with significant cost, complexity, and power consumption. We
present Helios, a hybrid electrical/optical switch architecture that can

deliver significant reductions in number of switching elements, cabling,

cost, and power consumption relative to recently proposed data center netw

ork architectures. In this talk, I''ll explore architectural tradeoffs and
challenges associated with realizing these benefits through the evaluation
of a fully functional Helios prototype.
