Modeling IO latency of SSDS

摘要

SSDs support various type of parallel IO mechanism. Thus, simulating IO latency of SSDs is difficult. In this paper, we develop SSD IO latency model for multi-channel, multi-way SSD. With the IO latency model, An SSD simulator can generate IO latency with a single thread. The IO latency models has 4% error rate compared with a real SSD, Intel X25-M.
