Performance improvement of OceanStor V3 where 12 Gbit/s SAS disks are supported but 6 Gbit/s SAS disks are also present
The rate negotiated between the expander and the 6 Gbit/s SAS disk is 6 Gbit/s. The single disk channel rate is 6 Gbit/s, which is sufficient to requirements. However, the rate negotiated between the expander and the initiator is increased to 12 Gbit/s, which is the shared rate of expanded disks. Therefore, the overall back-end bandwidth is improved.
