The correct answer is B. The maximum read bandwidth provided by the front-end link is 780 MB*2=1560 MB D. The effective read bandwidth provided by the hard disk = 40 MB*48 = 1920 MB. See the full explanation below for the reasoning.
Question
A company purchased a set of Huawei hybrid flash storage. The maximum read bandwidth that this storage product can provide is 3000MB. The planned configuration is: 48 600 GB, 15K SAS disks (single disk read bandwidth is 40MB), controller A and controller B each have one FC port (8Gb, unidirectional bandwidth 780MB, bidirectional bandwidth 1300 IB) as the front-end business port connected to the host. In this scenario, which of the following methods of calculating bandwidth (theoretical value) are correct? (Multiple choice)
Options
- AMaximum read bandwidth provided by the front-end link = 3000 MB
- BThe maximum read bandwidth provided by the front-end link is 780 MB*2=1560 MB
- CThe maximum read bandwidth provided by the front-end link is 1300 MB*2=2600 MB
- DThe effective read bandwidth provided by the hard disk = 40 MB*48 = 1920 MB
