Network-on-SSD: A Scalable and High-Performance Communication Design Paradigm for SSDs
In recent years, flash memory solid state disks (SSDs) have shown a great potential to change storage infrastructure because of its advantages of high speed and high throughput random access. This promising storage, however, greatly suffers from performance loss because of frequent "erase-before-write" and "garbage collection" operations. Thus. novel circuit-level, architectural, and algorithmic techniques are currently explored to address these limitations. In parallel with others, current study investigates replacing shared buses in multi-channel architecture of SSDs with an interconnection network to achieve scalable, high throughput, and reliable SSD storage systems. Roughly speaking, such a communication scheme provides superior parallelism that allows us to compensate the main part of the performance loss related to the aforementioned limitations through increasing data storage and retrieval processing throughput.
