A Multi-Tiered Storage Structure for Cloud Computing

摘要: During recent decades, cloud-based shared storage has become a popular solution. Nevertheless, current I/O subsystem assumes that the devices are homogeneous. Recently, multi-tiered system extends hierarchy by using SSDs to cache data from hard disks received significant attention. Thus, in this paper, we design an framework for storages multi-tenant environments. Specifically, propose two-tier per-user queuing structure solve user interference and device problem. Furthermore, on basis of credit-based request scheduling algorithm, introduce concept credits, instead credits previous schemes, proper charge users different types devices. The experimental results show our proposed is effective realizing multi-tiered-based systems cloud computing
