At the just-concluded ZTE Cloud Networking Ecosystem Summit, ZTE released a new storage product with a new architecture: distributed disk array KS20000.
Disk array and distributed storage are two major product forms of enterprise storage. Disk array, which is an integrated scale-up architecture of software and hardware, is highly efficient. It has been the main form of enterprise storage for thirty years. Distributed storage, which is regarded as a software-defined storage system based on COTS hardware, is capable of mass scale-out. With the popularization of virtualized infrastructure, there are more applications of distributed storage.
On the other hand, these two product forms have their own architecture weaknesses. Disk array, which is developed for the traditional IT architecture, cannot meet the elastic scalability requirements of virtualized infrastructure. Different types of disk arrays are used for different applications. In addition, data migration between different devices is costly, and data silos are easily formed in DCs. In distributed storage, the data path in the architecture is long and the software efficiency is low. This low efficiency cannot obtain satisfactory performance even through high configuration of hardware. Therefore, distributed storage products can only be used in the scenarios of warm/cold data storage.
Based on an in-depth understanding of the storage architecture and years of technical accumulation in disk array and distributed storage, ZTE has launched a brand-new distributed disk array product: KS20000. It boasts both the advantages of a centralized storage system and a distributed storage system. It is the first distributed storage product in the industry that can completely replace HFAs (Hybrid Flash Arrays) and AFAs (All Flash Arrays). Under the same configuration, its performance is even or better. It is also the first scale-out disk array product in the industry that has mass scaling capability. It can achieve linear growth in performance and capacity.
The major architecture features of KS20000 are described as follows:
The main architecture features of KS20000 determine that KS20000 has unique advantages over other systems in terms of expansion capability, performance, and cost performance support.
KS20000 has the following advantages:
Its high performance feature is displayed as:
Compared with traditional disk array products, the scale-out architecture of KS20000 eliminates the bottleneck of the controller capability and better matches the virtualized infrastructure. KS20000 can support 2-4,096 controllers and provide up to EB-level data management capability. It is applicable to various application scenarios from small edge sites to large cloud DCs.
As one of the few vendors in the storage field that have achieved self-development, ZTE has been investing in R&D of storage products for more than ten years, and has launched several generations of full series of disk array and distributed storage products. As the latest generation flagship storage product, KS20000 inherits ZTE's consistent features of high reliability, high performance and high quality. ZTE will continue to innovate, actively promote digital transformation, and work with partners for a win-win situation.
