The statement is correct. The Huawei OceanStor V3 series of storage systems, spanning from entry-level to high-end models, was designed with a 12 Gb/s SAS backend architecture. This ensures high-speed connectivity between the controller enclosures and the disk expansion enclosures. Official product documentation for all major V3 models, including the 2000, 5000, 6000, and 18000 series, consistently specifies the availability of 12 Gb/s SAS expansion ports as a standard hardware feature.

The statement would be false only if there were an OceanStor V3 model that did not support 12 Gb/s SAS for its backend connectivity. A review of the official hardware specifications across the entire V3 product line confirms that this is not the case; the 12 Gb/s SAS interface is a foundational component of the V3 architecture.
