Towards New Interface for Non-volatile Memory Storage

Shuichi Oikawa

Abstract

Non-volatile memory (NVM) storage is rapidly dominating the high end markets of enterprise storage, which requires high performance, and mobile devices, which require lower power consumption. As NVM storage becomes more popular, its form evolves from that of HDDs into those that fit the market requirements more appropriately. Such evolution also stimulates the performance improvement because it leads to the changes of the interface that connects NVM storage with systems. There is a claim that the further improvement of NVM storage performance makes it better to poll a storage device to sense completion of access requests rather than to use interrupts. Polling based storage can expand to become main memory based on NVM storage since there is no complex mechanism required to enable interrupts and access requests are processed one by one. This paper predicts that NVM storage will be in a form of main memory, and proposes constructing a file system directly on it in order to overcome its drawbacks when used simply as main memory. The performance projection of the proposed architecture is that accessing files on such a file system can reduce the overhead introduced by handling block devices.
