Canonical title: LegoOS: A Disseminated, Distributed OS for Hardware Resource Disaggregation
Question: What OS architecture can present a coherent machine abstraction over disaggregated processors, memory, and storage?
Context: Monolithic kernels assume resources share one server and do not naturally support independent scaling or failure domains.
Method: LegoOS uses a splitkernel with monitors colocated with each disaggregated resource and assembles virtual nodes for applications.
Evaluation: workloads=applications on an emulated disaggregated cluster; baselines=Linux; metrics=performance, packing, failure rate; results=Linux-comparable performance; qualitative packing/failure improvements
Interpretation: Disaggregation benefits from distributing OS responsibilities to the resource that owns the relevant state.
Reusable lesson: Split kernel services along hardware ownership boundaries while preserving a familiar application abstraction.
Applicability: Rack-scale disaggregated compute, memory, and storage fabrics.
Limits: Evaluation used an emulated commodity-server environment rather than native disaggregated hardware.
