Advertisement OceanStor Dorado is the next generation all-flash array (AFA) from Huawei. The Dorado uses five intelligent chips and a multitude of efficient algorithms to deliver 20 million input/output operations per second (IOPS), 100-microsecond latency, and hundreds of gigabytes of bandwidth. It more than satisfies the requirements of online transaction processing (OLTP) and online analytical processing (OLAP) in mainstream databases for the finance and carrier industries. In addition, OceanStor Dorado has adapted and enhanced algorithms for virtualization and supports ecosystem plug-ins ...

133,000@1 ms 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 ...
