DC-Store: Eliminating Noisy Neighbor Containers using Deterministic I/O Performance
summary
DC-Store claims deterministic I/O and removes noisy-neighbor effects by physically dividing an SSD into four NVM sets (prototype uses 2 channels per set on a 2 TB, 8-channel device) and by pinning container metadata I/O so page-frame reclaiming goes to per-container swap areas (swap-area pinning). The team modifies Linux 5.0.7 and Docker paths, runs FIO and LAMP/TPCC experiments, builds a hardware prototype plus kernel/userspace support, and reports 31% shorter average execution time with steady latencies, delivering deterministic SSD access time.
