Methodology for Anticipating Operational Budget to Ameliorate Hybrid Storage Clouds

摘要

The dramatic evolution of various disk and memory technologies has helped with the rapid establishment of hybrid storage environment comprising of heterogeneous storage units. In order to provide an improved and effective storage management, there exists a necessity of adapting S.M.A.R.T changes in the storage management stack that enables compact sensing, processing, decision making capability based on the importance of data, disk life span predicted on operational workloads and financial analysis estimating the disk replacement cost etc. This paper reviews system architecture for two faces of RAS (Reliability Availability Serviceability) storage cloud features namely disk breakage prediction independent of disk technology, host aware data tier based on disk life span and subsequently describes operational budget anticipation based on predicted disk failures.
