1. The development course of the storage industry.

The development history of the storage industry is the evolution of technology and demand. In order to meet the users' different application requirements, four kinds of products have been born. From the dimensions of generic and application-oriented products, the history, present and future storage products are plotted in quadrants.

Disk array is the main formation of universal storage, its development passed through direct storage (DAS), more than double disk array, accused of disk array, lateral extension of more disk array, according to the different business performance at the same time, adopt different storage medium, and gradually subdivided mixed arrays and flash memory arrays.

Network additional storage (NAS) originates from the file server, which is essentially a file system, which belongs to the application type storage, and is a storage product in different application scenarios and different hardware combinations. Because of the extensive use of files in storage, NAS has evolved from a proprietary system to a more common integrated NAS, namely SAN/NAS integration. In the future, it will develop into a dedicated distributed or cluster NAS trend.

Built-in hard disk of server storage belongs to applied storage, from the beginning of the form a complete set of application servers to software defined storage (SDS), and then to ultra fusion architecture (HCI), more and more present a specific application characteristics of the solution.

Object storage belongs to applied storage, originated in addressing the content of the technology at the turn of the century and the beginning dominated by a few large manufacturers such as EMC and amazon, now gradually developed more and more open source products, such as CEPH. In the field of public clouds, generally by the Internet enterprise own development based on the characteristics of their own needs, in the field of private cloud, object storage is commonly used in sea document filing, to replace the traditional tape library or cd-rom library, had not formed industry scale and leading brand. With the development of big data analysis industry, it is expected to form a certain scale market in the future.


Ii. Storage industry industry chain.

Where data is stored, big storage "industry chain can be roughly divided into memory chips/components/core software, storage, and solutions, system integration and storage services three levels. Upstream includes common chip/components (such as CPU, memory, connector, etc.), memory dedicated chip/components (such as HDD, SSD, SAS chip, etc.), and storage core software. Middle reaches are mainly storage and solutions, including enterprise storage (such as SAN, NAS, multi-protocol, etc.) and consumption level storage (such as mobile hard disk, flash disk, etc.); The downstream is mainly the system integration and storage service, which integrates the storage products with other products to provide the end users with the overall system or service mode.

1. Upstream: memory chip/components/core software.

The upstream of the storage industry is mainly semiconductor manufacturing, storage medium manufacturing, data transmission equipment manufacturing and core software development. Upstream manufacturers produce products that seem to be the basic components of "steel" and "cement", and the development of upstream industries has an important impact on the cost and technology of the industry. On the one hand, the core components such as chips, memory, hard drives, and other products upgrading will directly change the hardware structure of storage products and the upgrade of the entire product innovation, on the other hand, the main raw material for the change of supply and demand and price fluctuation will affect the production cost of this industry. Core software development is also very important. Only with the core software development ability, it is possible to reasonably use various raw materials to form high-quality storage products. The stronger the software, the stronger the ability to control and play the hardware. Taken together, storage upstream related hardware industry after years of development, has the high technology, the maturity of market pattern is stable, price competition fully, as a whole, is conducive to the stable development of the storage industry.

2. Middle game: storage and solution.

Middle reaches of the storage engine and solution generally refers to the use of upstream chip/components and core software, assemble into which has the function of data storage storage system, the use of "reinforcement" and "cement" building a house. The usage scenarios can be divided into consumer level/personal storage and enterprise/data center storage.

In addition to personal storage devices, the consumer level/personal storage includes PCS, tablets, smartphones, and smart terminal devices that could explode in the future. DRAM, NAND Flash, hard disk and other memory are widely used in these devices, which is an important part of data storage.

Enterprise/data center storage is mainly used in the construction of IT systems and data centers of government, enterprises and institutions. Due to storage industry upstream of the core software and hardware has high technical threshold, so the middle manufacturers generally adopt two kinds of competitive strategies: one is the control of the upstream manufacturers purchase, RAID card, hard disk, the core software of assembly, and even directly purchase the machine for OEM sales; Upstream and middle reaches, the other is a through independent research and development design core software, controller, interface components, etc., and other common parts with upstream manufacturers (such as a hard disk, fan, power supply, etc.) be assembled to form the whole machine products, such as huawei and macro Chinese fir.

3. Downstream: system integration and storage services.

IT requirements of the end user is often due to storage industry comprehensive calculation, three aspects of the network, storage, but usually downward industry manufacturers focus on storage, systems integration ability are relatively limited, so need to rely on professional system integrators to provide complete terminal products.


In recent years, with the rapid development of cloud computing and big data, cloud storage service providers have emerged gradually. Cloud storage was developed on the cloud computing concept extension, the cloud storage service no longer sell hardware, through the cluster or distributed file system, etc., makes the different types of storage devices connected to the network to work together, provide access to data storage and business functions, sold to individuals or enterprises, users need to purchase the performance only according to the actual capacity and related services, the ready-made "house" rent collection "rents". Cloud computing companies on the market at present basically with cloud storage services, such as Google, AWS, Microsoft, tencent, ali cloud cloud, cloud computing giants such as baidu cloud, and focus on niche of seven NiuYun, Letv cloud, etc. Cloud storage providers provide different levels of cloud storage services based on differentiated business categories and data values. Current public clouds cloud storage service is mainly geared to the needs of individual users, and corporate users of important data backup, for enterprise users with high performance, high reliability, high safety storage services are still in the preliminary exploration stage, is expected to future cooperation with middle manufacturers have a lot of space.

Storage industry end-users are widely distributed in all of data storage requirements of all walks of life, covers most areas of the national economy, the size of the market and development potential is tremendous, is not because of the abnormal fluctuations of individual industry caused great influence on the whole market demand.
