摘要

SSD (Solid-State Disk) is a storage device that is considered as an HDD replacement, due to its potentials such as high random I/O performance, reliability and low-power consumption. SSDs are widely being used these days, from small-size mobile equipment to high-end storage subsystems. In this paper, we introduce NF-hybrid (New-Form of hybrid) file system whose primary objective is to utilize performance potentials of SSDs, while addressing their drawbacks. The main obstacle in building large-scale storage subsystems solely composed of SSDs is the higher cost per capacity over HDDs. Furthermore, in applications generating sequential workloads, using disk arrays can deploy a similar performance bandwidth to SSDs. Therefore, blindly adopting SSDs to storage subsystems is not a good way to provide better I/O performance. NF-hybrid exploits a cost-effective way of utilizing SSD's performance advantages while offering a large-scale storage capacity. NF-hybrid's address space is provided with a hybrid structure where both HDD and SSD are integrated through the flexible internal structure. In addition to the hybrid internal structure, NF-hybrid supports the reconfigurable SSD address space by allowing multiple, logical data sections that are composed of the different extent size each. On top of those data sections, files can transparently be mapped to the appropriate data section, by considering their access characteristics. The performance evaluation verifies the effectiveness and suitability of NF-hybrid.
