1. Distributed good storage
New storage applications and new requirements are changing with each passing day, and new technologies for distributed storage are developing vigorously.
What is good storage? In layman's terms, it is easy to use, solid and efficient.
Professionally speaking, it is stable and reliable, highly available, highly scalable, high-performance, high-efficiency, and easy to manage.
The RAS feature is a necessary prerequisite for good storage, so it goes without saying.
The key criteria for a good storage product are high scalability, high performance, and low cost.
Distributed storage emerged as the times require, and SDS has become the mainstream of the storage market.
In 2021, the inflection point for SSD flash memory to fully replace HDD hard disks has appeared.
All-flash SDS 2.0 is accelerating its development and will soon become the mainstream of the storage market.
Focusing on the high expansion, high performance, low cost/high efficiency of All Flash SDS 2.0,
EB-level ultra-large scale, NVMeoF all-flash memory, DPU, AIOps, etc. will be the hotspots in the development of distributed storage technology.
2. New opportunities in the storage market
SDS storage is replacing traditional storage in an all-round way. All-flash SDS 2.0 accelerates this process and gradually penetrates into core applications.
The key requirements of emerging markets are high scalability and high performance/low latency, such as bare metal cloud computing, big data, AI/HPC/HDPA,
Both traditional storage and SDS 1.0 are not enough. This is a great opportunity for all-flash SDS 2.0.
Industrial upgrading focuses on storage scalability and cost reduction, such as radio and television media, video surveillance, HPC,
Capacity-based SDS 1.0 better meets this demand and has become the mainstream in the market.
The cost of SSD continues to drop, and it will develop into performance-based SDS 2.0 in the future.
Xinchuang project requires autonomy and controllability, and prefers to build an advanced storage system from 0 to 1.
SDS 1.0 is mainly open source, and all-flash SDS 2.0 is the only way for Xinchuang storage.
3. Small insight into storage technology
Domestic open source SDS is too involuntary, and encourages the construction of SDS from 0 to 1, especially the advanced all-flash SDS 2.0.
SDS block storage, almost all Ceph, homogeneous competition and performance bottlenecks, NVMeoF all-flash block storage is a good direction.
SDS file storage, mainly Lustre/Gluster/CephFS/BeeGFS, is a good product for Qumulo/Wekaio's next-generation all-flash file storage, and file storage will usher in a new development.
SDS object storage, minio besides Ceph, and intel DAOS push object storage to the high-performance market.
