QUESTION NO: 1
A company purchased a set of Huawei hybrid flash devices to run services on a virtualization platform. The host system uses Huawei multipathing software and uses an Ethernet switch to connect to the two controllers of the storage system. Storage engineers discover service outages and delays on hosts. Upon inspection, they found that the active link of the multipath software was being switched continuously. This problem can be solved by disassembling the multi- directional software on the premise of ensuring service reliability.
