A Survey on Tiering and Caching in High-Performance Storage Systems
Although every individual invented storage technology made a big step towards
perfection, none of them is spotless. Different data store essentials such as
performance, availability, and recovery requirements have not met together in a
single economically affordable medium, yet. One of the most influential factors
is price. So, there has always been a trade-off between having a desired set of
storage choices and the costs. To address this issue, a network of various
types of storing media is used to deliver the high performance of expensive
devices such as solid state drives and non-volatile memories, along with the
high capacity of inexpensive ones like hard disk drives. In software, caching
and tiering are long-established concepts for handling file operations and
moving data automatically within such a storage network and manage data backup
in low-cost media. Intelligently moving data around different devices based on
the needs is the key insight for this matter. In this survey, we discuss some
recent pieces of research that have been done to improve high-performance
storage systems with caching and tiering techniques.Comment: Ph.D. Research Exam Repor
