In the power-on process of Huawei distributed storage devices, if the storage node power policy has been set to "power on but not boot up", it will not automatically power on after the power is turned on. Engineers need to manually press the power button on the front panel of the storage node to power on the device.
- A . True
- B . False
If a performance Issue occurs in Huawei flash storage, an engineer can perform optimization operations according to the storage performance optimization process.
Which of the following statements is false about the performance optimization process?
- A . In the information collection phase, the engineer needs to collect basic information about applications and data, such as the impact of application configurations on data, data size, and read/write ratio.
- B . In the test and application phase, the engineer needs to test the configurations to check whether the optimization objective is achieved. If yes, the engineer can put the system into use.
- C . In the optimization analysis phase, the engineer needs to specify the performance optimization objective, find out the performance bottleneck, and identify the parts that play a key role in Improving the system performance.
- D . In the optimization operation phase, the engineer needs to deploy DR for the service system, and needs to modify multiple configuration at a time during the optimization configuration.
During the use of Huawei flash storage, an engineer wants to calculate the valid write bandwidth of disks.
Which of the following formulas can calculate disk valid write bandwidth?
- A . Valid read bandwidth of disks = Read bandwidth of a single disk x Number of disks x (Number of system disks / Total number of disks)
- B . Valid write bandwidth of disks = Write bandwidth of a single disk x Number of disks
- C . Valid write bandwidth of disks = Write bandwidth of a single disk x Number of disks x (Number of data disks / Total number of disks)
- D . Valid write bandwidth of disks = Bandwidth of a single port x Number of ports
A company purchased multiple Huawei converged storages for remote replication services. If the primary LUN fails in this service scenario, the administrator needs to perform the "Cancel remote replication pair slave resource protection" operation to restore the service, that is, manually set the slave LUN to be writable.
- A . True
- B . False
OLTP is the main application of traditional relational databases, mainly for basic and daily transaction processing.
Which of the following descriptions about OLTP is wrong?
- A . In OLTP business, the bandwidth indicators of the backend ports usually do not require special attention, that is, they do not need to be monitored.
- B . From the database level, the amount of data involved in reading, writing, and modifying each transaction is very small, and many users will access it at the same time.
- C . In OLTP business, you usually need to pay attention to the controller’s average I/O response time and average CPD utilization indicators.
- D . From a storage perspective, it is usually read sequentially, and when the read operation is in progress, the write operation data will be stored in the temporary table space
Which of the following file system sharing methods does Huawei all-flash storage system not support?
- A . HTTP Sharing
- B . CIFS sharing
- C . FTP sharing
- D . SFTP sharing
- E . NFS Sharing
When engineers use the Iometer performance testing tool, they can set operating parameters, start and stop tests through the graphical user interface.
- A . True
- B . False
In Huawei OceanStorDorado series storage, the cache write policy is set to write-through by default. The write policy may change when battery failure, system single control, etc. occur.
- A . True
- B . False
Huawei’s all-flash storage supports enabling or disabling the SmartCache function for a specified () or file system.
A financial customer purchased a Huawei flash storage for subsequent business deployment. During the storage configuration process, the administrator found that after mapping the LUN for the application server, the mapped LUN could not be found on the application server side. Please analyze which of the following reasons may cause this abnormal phenomenon? (Multiple choice)
- A . Storage pool failure
- B . Serial port connection parameter settings are wrong
- C . In Unix or Linux environment, the device node file is lost
- D . In the HP-UX environment, the application server does not have a LUN mapping with host LUN ID 0.
