Case:
Customers In order to calculate the scientific research center, the disk cabinet storage of a scientific research project computing platform is damaged, causing the calculation data to be unable to access.The specific environment of the customer is that the host server is two Dell 2U server, stored as Dell MD3200 header, with 3 MD1200 cabinets, divided into three sets of LUN nodes for server use.The server OS is the Reahat 5 Enterprise Enterprise, which runs a set of scientific test data and uses a specific dedicated database system.
Solution:
