Abstract

The RAIN project is research collaboration between Caltech and NASA-JPL on distributed

computing and data storage systems for future space-borne missions. The goal of the project is to

identify and develop key building blocks for reliable distributed systems built with inexpensive off-

the-shelf components. The RAIN platform consists of a heterogeneous cluster of computing and/or

storage nodes connected via multiple interfaces to networks configured in fault-tolerant topologies.

The RAIN software components run in conjunction with operating system services and standard

network protocols. Through software-implemented fault tolerance, the system tolerates multiple

node, link, and switch failures, with no single point of failure. The RAIN technology has been

transferred to RAIN finity, a start-up company focusing on creating clustered solutions for improving

the performance and availability of Internet data centers.
