Canonical title: Asymmetric RAID: Rethinking RAID for SSD Heterogeneity | |||
Question: Can RAID use heterogeneous SSD capacity and performance without forcing symmetric participation in every stripe? | |||
Context: Conventional RAID assumes similar devices and lets the weakest member constrain capacity or speed. | |||
Method: Asymmetric RAID distributes data unevenly and exposes different portions of stripe address space to devices for placement according to their characteristics. | |||
Evaluation: workloads=; baselines=symmetric RAID; metrics=capacity utilization; performance; rebuild behavior; results=no quantitative result verified | |||
Interpretation: Stripe geometry can be a placement policy rather than a fixed equal partition. | |||
Reusable lesson: Represent heterogeneous capacity/performance explicitly instead of normalizing every device to the minimum. | |||
Applicability: RAID arrays containing heterogeneous SSDs. | |||
Limits: Preliminary workshop work; accessible primary sources do not provide a complete evaluation, recovery analysis, or numbers.</nowiki> | |||
