报告摘要:

现有的SSDHDD等存储设备都用传统的MCU和固件来管理和控制存储数据。随着新型存储介质技术如闪存、PCMRRAMMRAM等不断涌现,管理和控制数据存储变得越来越复杂。另一方面,在大数据时代,结构化数据和非结构化数据的指数型爆发增长对存储管理提出了空前的挑战,大数据应用的多样性也对存储的I/O性能、安全性和可靠性提出了更高的要求。因此,现在已经到了一个新的历史时刻,需要我们重新考虑存储控制器的架构,使得更好的适应大数据和新存储介质的发展。

为此,我们首次提出一个新概念——数据存储处理器(Data-storage Processing Unit,简称DPU)。DPU是一种专门针对大数据、云计算特性而定制设计,用于管理、控制和分析大数据并对数据进行分类。DPU把智能带入到SSD存储设备中,通过机器学习算法来不断学习和优化I/O性能,提高数据可靠性、安全性和可用性,从而针对各种不同的大数据应用达到最优的管理和控制性能。

 

Traditionally, storage devices such as HDD and SSD are managed and controlled by standard MCUs and firmware running on them. As new storage technologies emerge such as flash memory, PCM, Memristor, and MRAM, management and control of storage devices have become more and more complex. On the other hand, data that are stored in storage devices grow exponentially encompassing all kinds of data including structured and unstructured data, which further complicates data storage management. In addition, variety of big data applications demands high I/O performance and high data reliability/availability, placing stringent requirements on storage devices. Therefore, it has come to a historical point where we should reconsider storage controller’s architecture to keep pace with the explosive growth of big data and fast emergence of new storage media technologies.

 

We introduce and have built a storage controller ASIC with built-in intelligence, referred to as DPU for Data-storage Processing Unit. DPU manages, controls, analyzes, and classifies big data at the place where they are stored. The idea is to place sufficient intelligence closest to the storage devices that are experiencing revolutionary changes with the emergence of storage class memories. Machine learning logics are a major part of DPU that learns I/O behaviors inside the storage to optimize adaptively I/O performance, data reliability, security, and availability for a variety of applications.
