Abstract

This paper proposes new methods with Host Memory Buffer to improve IO performance in NVMe interface. Although Host Memory Buffer is a versatile memory architecture, it has been considered limitedly as metadata cache such as Logical-To- Physical table. The proposed architecture uses Host Memory Buffer as data cache with modification of an NVMe command process and the additional DMA path between system memory and Host Memory Buffer. The proposed architecture improves the performance of IO request by 23% in case of sequential writes compared to a device buffer architecture.
