RAID control/data paths should exploit the network topology and overlap protection work rather than emulate a local controller. Disaggregated RAID Storage in Modern Datacenters workloads=dRAID microbenchmarks; object-store workloads; baselines=conventional disaggregated RAID; metrics=bandwidth; object-store throughput; reconstruction efficiency; results=up to 3x bandwidth; 1.5–2.35x object-store throughput How should RAID be redesigned when disks, compute, and network are disaggregated across a datacenter? lab Redesign recovery and parity flows around disaggregated peer bandwidth, not a centralized legacy abstraction.

Canonical title: Disaggregated RAID Storage in Modern Datacenters Question: How should RAID be redesigned when disks, compute, and network are disaggregated across a datacenter? Context: Centralized RAID controllers and blocking multistage writes underuse peer bandwidth and magnify network overhead.

Evaluation: workloads=dRAID microbenchmarks; object-store workloads; baselines=conventional disaggregated RAID; metrics=bandwidth; object-store throughput; reconstruction efficiency; results=up to 3x bandwidth; 1.5–2.35x object-store throughput Interpretation: RAID control/data paths should exploit the network topology and overlap protection work rather than emulate a local controller.
