The Huawei OceanStor Dorado systems are a family of all solid-state dual controller storage systems with a common architecture. The Dorado models are all-flash versions of the base OceanStor systems – 5000, 6000, 8000, and 18000. The Dorado systems consist of the V3 series and the newer generation V6 series. More details on the base systems are in the corresponding Evaluator Group Huawei OceanStor product analysis. The models differ in physical packaging and in the processor and memory for the controllers. The Dorado systems are targeted at accelerating applications such as databases, virtual desktop, and server virtualization. The Dorado (officially OceanStor Dorado) line uses Huawei SSDs attached by 12 Gb/s SAS or by PCIe using the NVMe protocol. All models utilize modular architecture, standard racks and enclosures and support additional 2.5” SFF device enclosures. The Dorado system supports block access.
The OceanStor Dorado systems are adapted from the “T” models and run the same base embedded software system and support additional add-on software features. The Huawei Dorado all flash systems compete against EMC Unity all flash models, NetApp All Flash FAS, HPE Primera, PureStorage FlashArray and other leading all flash systems.
