100-μs latency, 10x faster than the industry average
Huawei OceanStor Dorado not only provides high IOPS, but can also reduce the latency to 100 μs in scenarios with a high cache hit ratio. For example, a test was performed with the SLOB tool. The 4-controller OceanStor Dorado 18000 achieved a 75% read cache hit ratio, 220,000 IOPS, and less than 100-μs latency in the 25% update and 8:2 read/write ratio scenario (the most typical database I/O model). Even if the IOPS of the core service system reaches 200,000, OceanStor Dorado can still keep the latency at about 100 μs. This is 10x the 1 ms latency of the all-flash storage of other vendors and far exceeds the requirements of mission-critical applications.
