Instead of having server units with "converged" compute, memory, and storage resources, a disaggregated data center (DDC) has pools of resources of each type connected via a network. Cirrus also provides an efcient in-terface for communication between tasks through distributed memory. . Our solution is to "disaggregate" monolithic servers into distributed, network-attached hardware components that can each manage its own resource and can fail independently.
