NEW QUESTION 152
The engineer went to a customer unit to install Huawei OceanStor 9000 equipment (a total of 5 Huawei OceanStor 9000 C Nodes, both front and rear are 10GE TOE networking, and the TOE network card is installed on site). The equipment has been put on the shelf, and the signal cable and the power cord will be connected next, and software debugging. Due to the tight construction period, the following phenomena occurred during the hardware installation process. Which of the following descriptions of these phenomena are wrong? (Multiple Choice)
- A. The signal cable labeled "NODEO1A0-0" is inserted into the network port at A0-1, and the signal cable labeled "NODEO1B3-1" is inserted into the network port at B3-0. Because the two network ports of the same network card are paired etc., you can plug the wires in different positions, and you cannot adjust them.
- B. There are two stacking copper cables connected to the CE6850 switch. One of the faulty cables needs to be replaced later. Since it does not affect network communication, you can perform basic software commissioning first.
- C. In order to manage each Node separately, all Nodes must connect the NICo port to the management network.
- D. There are two ways of inserting the TOE network card into A0, B1 and A0, B3 in the 5 devices. Since they are all inserted in the PCle slot, it will not affect the system deployment or network bandwidth, so it is not necessary to adjust.
Answer: A,D

During the copying process, for the special identification of all zero data, only a small special page is transmitted to the opposite end, and the full amount is no longer transmitted.
- C. HyperMetro uses the granularity of host I/O to perform concurrent and mutual exclusion on the LBA interval between host I/O accesses and distributed range locks, so as to achieve the purpose of two-way real-time synchronization. This solution can save unnecessary data transmission between arrays. Auxiliary bandwidth, and effectively reduce the number of data transmissions.
