A company purchased a set of Huawei hybrid flash storage. This storage product can provide a maximum read bandwidth of 3000 MB. It is planned to configure 48 600 GB, 15K SAS disks (single disk read bandwidth is 40MB). There is an FC port (8 Gb, 780MB one-way bandwidth, 1300IB two-way bandwidth) connected to the host as a front-end business port.
Which of the following methods for calculating bandwidth (theoretical value) is correct in this scenario? (Multiple Choice)
