Description

technical field

[0001] The present invention relates to the field of computers, in particular to a storage system and a method for implementing the storage system. Background technique

[0002] The storage system is one of the most important components in a computer system. People have always wanted storage systems with high speed (high IOPS and high throughput), high reliability, and low cost.

[0003] Most existing servers or personal computers still use hard disk drives (HDDs) as the primary storage system. Despite the lower cost of HDD-based storage systems, improvements in HDD access latency have lagged far behind improvements in capacity in recent years. High latency will greatly affect the IOPS (input / output operations per second) value. Especially for workloads where random I / O dominates, such as database workloads, the HDD will become a performance bottleneck. For workloads where sequential access is dominant, HDDs have better access performance. For example, a ...
