Fair Allocation of Asymmetric Operations in Storage Systems

Managing the trade-off between efficiency and fairness in a storage system is challenging due to high variability in workload behavior. Most workloads are made up of a mix of asymmetric operations (e.g. read/write, sequential/random, or striped/isolated I/Os) in different proportions, which places different resource demands on the storage device. The problem is to allocate device resources to the ...
