The evolution of storage has been dramatic. As computing has become an integral part of our daily activities, storage media has had to evolve to keep pace, moving from tape and mechanical hard disk, to solid state hard disk, NAND, and now emerging 3D XPoint technologies.

Demand is only expected to increase. The data boom created by connected devices coupled with growth areas such as Artificial Intelligence and Machine Learning bring higher expectations — greater capacity, scalability, and faster access, not to mention increased availability and reliability. These challenges have resulted in the rise of distributed storage systems and cloud-based services, to help providers meet those demands. Software plays a key role in this transformation. The emergence of software-defined storage enables more scalable and flexible solutions, as well as greater levels of management and orchestration. Offerings such as virtual machine and container persistence storage help meet a growing range of business needs.

Open source provides the foundation for modern storage systems and a platform for rapid innovation. Intel has been active in the open source software community for 20+years, and our contributions to storage technologies such as Intel® Storage Acceleration Library （ISA-L）, Storage Performance Development Kit （SPDK）, and the Ceph project help accelerate performance for storage virtualization platforms.

As a leader in developing storage hardware and software, Intel recognizes the importance of the Chinese ecosystem to the growth of the storage market. It is with great pride we present this book as a resource to the China storage community.
