Self-Determining Resource Control in Multi-Tenant Data Center Storage with Future NV Memories
Chihiro Matsui, Ken Takeuchi · 2019
Self-determining resource control (SDRC) of hierarchical non-volatile memories is proposed for the multi-tenant data center storage. Proposed SDRC adjusts the capacity of emerging storage class memories (SCMs) such as MRAM (memory-type SCM) and PRAM (storage-type SCM) by considering the tenant-specific Service Level Agreement (SLA). Proposed SDRC is a self-contained system and therefore is immune to the frequent generation transition of non-volatile memories with different bit cost, latencies, and I/O bandwidth. This paper also introduces the circuit design of future scaled and high capacity PRAM as S-SCM, and the future interface for SCMs. The vertically integrated total optimization is achieved from memory device, memory circuit, and application to service and memory hierarchy-level. Evaluation results show that the optimal balance of performance and costs are automatically adjusted by SDRC and the Quality of Service requirement is achieved.
