Abstract:

Solid state disks (SSDs) become more and more popular in personal devices and data centers. Flash chips can be packaged in Hard disk drive (HDD) form factors and provide the same interface as HDDs. This character makes SSDs easily replace HDDs in existing storage systems. PCIe-based SSD can provide a higher I/O performance, but it is still a little expensive. This paper studies the feasibility of Redundant Arrays of Independent SSDs (RAIS) with different filesystems. We comprehensively analyze the performance of RAIS constructed by SATA SSD and PCIe SSD individually. We investigate different RAIS configurations (RAIS0, 5, 6) and filesystems under various I/O access patterns. Finally, we illustrate our serval key findings and recommendations for building RAIS.
