제목	Disaggregated RAID Storage in Modern Datacenters
궁금했던 점	How should RAID be redesigned when disks, compute, and network are disaggregated across a datacenter?
해본 것	dRAID enables peer-to-peer disaggregated data access, nonblocking multistage writes, pipelined I/O, and bandwidth-aware reconstruction.
당시 조건	Venue: ASPLOS. Year: 2023. Centralized RAID controllers and blocking multistage writes underuse peer bandwidth and magnify network overhead. Verification: official_abstract; confidence=high.
실제 결과	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
왜 그랬는지	RAID control/data paths should exploit the network topology and overlap protection work rather than emulate a local controller.
다음에 기억할 것	Redesign recovery and parity flows around disaggregated peer bandwidth, not a centralized legacy abstraction.
언제 맞는지	Datacenter disaggregated storage and object stores. Limits: Benefits depend on topology, network balance, failure model, reconstruction traffic, and object-store integration.

Verification: official_abstract; confidence=high. 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. Method: dRAID enables peer-to-peer disaggregated data access, nonblocking multistage writes, pipelined I/O, and bandwidth-aware reconstruction. 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. Reusable lesson: Redesign recovery and parity flows around disaggregated peer bandwidth, not a centralized legacy abstraction. Applicability: Datacenter disaggregated storage and object stores. Limits: Benefits depend on topology, network balance, failure model, reconstruction traffic, and object-store integration.
