A government customer purchased a Huawei OceanStor Pacific9550 storage. During an inspection, the engineer found that the onboard optical port indicator on the rear panel of the device was always yellow, indicating that data was being transmitted at a rate of 25 Gbit/s.
- A . True
- B . False
During routine inspection, an engineer of a bank found that the interface module of a Huawei flash storage device was down. At this time, he could directly remove and insert the interface module without any prior operation.
- A . True
- B . False
When delivering the Huawei OceanStorPacific storage project, a Huawei engineer vigorously promoted the SmartEncryption data encryption feature of distributed storage to the customer. Which of the following descriptions of this feature is wrong?
- A . This feature supports encrypted writing using any protocol such as NFS, CIFS, HDFS, or S3, and then decrypted reading using any protocol such as NFS, CIFS, HDFS, or S3
- B . File service clients can write plain text data via NFS/CIFS/DPC protocols
- C . Huawei OceanStorPacific series distributed storage supports hard disk encryption. All data issued by the business is stored on encrypted disks.
- D . When reading through the DPC or NFS protocol, the encrypted disk obtains the identity authentication key from the key management server, then reads the ciphertext data in the encrypted disk and decrypts it, and then returns the plaintext data to the protocol layer, which returns the plaintext data to the client application
Daily management of Huawei flash storage systems involves power-on and power-off operations.
Which of the following descriptions about powering on and off the storage system is wrong?
- A . For Huawei OceanStor Dorado6800 storage, when the controller enclosure is powered on, the disk enclosures cascaded to it will automatically power on.
- B . To power on the storage system again after an emergency power off, follow the steps to power on the storage system. That is, press the power button on the controller.
- C . When all controller boxes in the cluster are powered off, you can log in to the BMC system through the BMC external management IP and execute the power-on command to power on all controller boxes in the cluster.
- D . Before powering on the storage system, ensure that all cascading cables are correctly connected. If the cascading cable connection method is adjusted after powering on, the storage system may malfunction.
In Huawei’s converged storage, the () end-to-end fully interconnected architecture includes front-end 4-controller shared interconnection, controller full interconnection, and back-end 8-controller shared interconnection. Among them, the front-end 4-controller shared interconnection means that the interface card is fully interconnected with all controllers in the engine through a shared interface card, and the shared card can access 4 controllers simultaneously in AA mode.
In distributed storage, the EC mechanism can provide better redundant protection for data.
Which of the following descriptions of the EC mechanism are wrong? (Multiple choice)
- A . In the node-level security scenario, when the number of storage nodes is 2NH, the N+ redundancy ratio is used. When the number of (N+M)/Ms storage nodes is <N+M, the N+M:1 redundancy ratio is used.
- B . In the node-level security scenario, after capacity expansion, when the number of storage nodes reaches 2N+/, the system will automatically balance N+M:1 to N+I through the background.
- C . When expanding capacity, if the current hard disk pool can support a larger EC redundancy ratio, the N value of the hard disk pool is usually expanded after stopping the business.
- D . Node-level security layout has the highest space utilization rate. The hard disk of the faulty node can be taken over by the normal node, and the scope of the fault impact is smaller.
In actual business scenarios, the characteristics of engineering data and earthquake geological data are similar to database backups. The storage format of these data is the same, but the similarity between the data is low. At this time, the () characteristics of flash storage can be used to reduce the storage space occupied by the data, thereby reducing investment costs and operation and maintenance costs.
A financial customer newly purchased several Huawei distributed storages for business deployment, with a total of 6 nodes, including 2 computing nodes and 4 storage nodes, and the business, storage, and management switches were deployed independently.
An engineer needs to plan interfaces for a 25GE switch. Which of the following descriptions about interface planning is wrong?
- A . In interface planning, engineers can reserve interfaces. To shut down reserved interfaces, engineers can execute the shutdown command.
- B . If engineers want to plan M-LAG interfaces, each switch can use two 100GE interfaces to configure M-LAG.
- C . In this scenario, engineers do not need to plan aggregation interfaces, but must plan 8 MGT interfaces to connect to the BMC/management switch.
- D . If engineers want to plan node interfaces, each switch can use 4 to 6 25GE interfaces to connect to computing nodes and storage nodes in sequence.
A government customer purchased several Huawei flash storages for business deployment. The administrator configured the SmartVirtualization heterogeneous virtualization feature on the storage. Which of the following descriptions of this feature are wrong? (Multiple choice)
- A . After the administrator configures this feature, when the application server sends a request to read data from an external LUN, the eDevLUN of the local storage system receives the data read request and reads the data from the external LUN of the heterogeneous storage system.
- B . When the administrator configures offline takeover of a third-party heterogeneous storage system, there is no need to first establish a logical connection between the local storage system and the heterogeneous storage system.
- C . When the heterogeneous storage is a third-party storage system, the local storage system needs a license file to authorize its use
- D . When the heterogeneous storage system is a Huawei storage system (excluding OE storage systems), the heterogeneous storage system needs to obtain a license to use the SmartVirtualization feature.
The alarm level indicates the severity of the impact of the alarm on user business. The important alarm level indicates a global alarm that has caused customer business interruption or system paralysis.
- A . True
- B . False
